Do you Need a New Roof?

Your roof probably doesn’t take too much of your attention. It does it’s job perfectly well, until it doesn’t. Then you might encounter water leaks, structural damage, mould and numerous other problems that can cost you tens of thousands of dollars in extra costs and clean up.


Your roof, unless it is metal, is not going to last forever. There is a limited lifespan to even the best quality roofing materials, so it’s best to be proactive and bring in a professional roofing company to inspect your roof if you notice any signs of deterioration. Tony William Roofing & Exteriors offers inspections that will tell you the exact state of your Calgary roof. 


How to Safely Inspect Your Own Roof

From time to time, it’s a good idea to keep an eye on the exterior of your home. Your roof, performs a critical barrier against sun, rain, snow, wind, falling debris and everything else that nature has to offer. It’s a good idea to make sure your roofing materials remain in good shape.

There is no need to climb up on your house and risk injuring yourself or damaging your roof. You can safely do a basic roof inspection from the ground. Visible damage such as missing, cracked or curled shingles are clear indicators of a needed roof replacement.

If you can see from the ground, take a special look around skylights, flashings, vents, chimneys, and other joints to see if they are damaged or pulling way. These are the areas most prone to water leakage.

If you are unsure about the state of your roof, give us a call at Tony William. We offer no-charge roofing inspections to give you an accurate evaluation you can trust. Having a professional climb on to your roof is the best way to gauge the current quality of your roofing.


Potential Shingle Damage to Look Out For

Missing Shingles

Shingles blown off in a storm or damaged by a fallen tree will need to be replaced quickly. If you see missing shingles on your roof or notice broken material in your yard, call Tony William for an inspection. Don’t wait for further wind and water damage to penetrate into the underlying roof structure.

Determining if your roof's shingles need replacement

Broken or Damaged Shingles

Shingles can be damaged from wind, snow removal and falling debris. Broken or missing shingles can allow water to penetrate under roofing materials leading to leaks and other serious damage. In Calgary, hail is a major cause of roofing damage, so if your home has been hit by a major storm, it’s a good idea to get an inspection. It’s likely you’ll be covered against hail and other weather damage by your home owner’s insurance. You will need to know the date of the storm to be covered by insurance, so make sure you make a record of when the damage occurred. 

Bare Shingles

It is normal for the the protective surface of shingles to wear off over time. As the asphalt begins to harden, the granules will begin to fall off and leave shingles bare in spots. This is another great reason to stay off your roof. Walking around your roof can prematurely damage the surface of your roofing materials.

Waving or Buckling of Shingles

Can you see signs of buckling or waviness in the underlying roof structure. If you notice any kind of warping or undulation in your roof, it is likely that shingle edges are lifted away from the roof, making them more susceptible to wind, rain and hail damage. Warping like this can often be attributed to inadequate ventilation in your attic, leading to moisture buildup and wood rot. Lower quality or thinner roof sheathing wood may also be a contributing factor.

Sun Damage

Did you know that Calgary has one of the highest amounts of sunshine in North America? Those long summer days take a toll on your roof, leading to deterioration of the shingle structure. South and West facing roofing sections will always have the most sun exposure so take a look at those areas to see if there are visible signs of sun damage. You might notice a discolouration of shingles or see some of the other problems mentioned above.


How much does it cost to replace a roof?

The cost to replace your roof can vary greatly by the type of roofing materials you choose. Inexpensive roofing materials will have shorter lifespans so you’ll need to replace your roof more often. In contrast, a metal roof, will often last longer than the life of your home. While more expensive initially, metal roofing and other high quality materials, will save you lots of money and hassles over the long run.

Our Tony William sales consultants will clearly explain all your options so you can choose the best roofing material for your home and budget.

Of course, the larger your home, the more roofing materials you will need. Roofing materials are measured by the “square”. One square is 10’X10’ or 100-square-feet.

In order to accurately calculate the size of your roof, your roofer will multiply the length and width of each roof section to get the square footage. It’s common to add about 10 percent for waste. The total square footage of your roof divided by 100 is how how many squares you'll need.

For a rough estimate , a 2,200 square foot house will need about about 33 to 34 squares of roofing material. Keep in mind that the complexity of your roof’s shape and it’s slope can add to the total surface area.

It’s always a good idea to save at least one extra bundle of shingles after a roof replacement for potential roofing damage after a hail storm or heavy winds.

Removing Old Shingles

Technically, it is possible to save money on your roof replacement by placing new roofing materials over the old. While building codes permit two layers of roofing materials, that is something we’d never do at Tony William Roofing & Exteriors. We ALWAYS completely remove old roofing materials to make sure there is no rot, water damage, or insect infestation underneath. That is the only way to guarantee a quality roofing installation.

At Tony William, we never cut corners. Every job has to be completed to the utmost perfection. It’s this attention to detail and unrelenting focus on quality that allows us to offer our 10-year roofing installation warranty.

After removing old roofing materials, we can fully inspect and repair the underlying structure of the roof. If the wood sheathing or rafters show signs of leakage, mould or other damage, they may also need to be replaced. There is no way to fully gauge the quality of the underlying roof and structure until the old shingles are removed. Starting with a sturdy roofing base, we then add a new moisture barrier roofing underlay before installing your new roof. That will keep your roof strong for many years to come.


Types of Roofing Materials

There are many different types of roofing materials, and to complicate matters, various roofing suppliers use their own brand names for similar products. Add in the numerous styles, textures, and colours available, and your roofing options become virtually endless. Don’t worry, our roofing advisors at Tony William are happy to take the time to explain all your options clearly and up-front.



Shingles are the most common roofing material and have the largest number of suppliers and types. Your roofing consultation will include an explanation of all the different options to help you choose the type of shingle best suited for your home. After that, you’ll be able to select the perfect colour and style. There are so many, beautiful options on the market now, so you’re sure to get exactly what you want.

Shingle Types

Fibreglass Shingles

In Canada, most shingles are fibreglass based. Fibreglass shingles are typically thinner, lighter, and carry a better fire rating than asphalt shingles. Fibreglass shingles are flexible and retain that flexibility in Calgary’s cold weather. That flexibility is important to withstand strong winds. Furthermore, the granules in fibreglass shingles are designed to reflect more sunlight to help reduce sun deterioration.

Organic Shingles

Organic shingles are simply asphalt shingles. They are not environmentally friendly or green, as the name may imply. The “organic” refers to the non-synthetic under layer of the shingles, as opposed to the synthetic fibreglass layer found in fibreglass shingles.

From the surface, both asphalt (organic) and fibreglass shingles appear the same. The base materials of both are still asphalt and granules. The only difference is the base material. Organic shingles typically use recycled paper such as newspaper or cardboard. The layer of fibreglass in fibreglass shingles tends to be more moisture and heat resistant than “organic” materials.

Asphalt Shingles

Asphalt shingles are the most common shingles on homes today. They have have been used for decades in North America. Modern asphalt shingles are made of fiberglass but are layered between asphalt and ceramic granules. These shingles are light weight, easy to install and tend to be the least expensive roofing option. Some manufacturers claim 20 or 30 year lifespans, but asphalt shingles are more susceptible to weather deterioration so are unlikely to last that long.

There are two main types of asphalt shingles: Laminated shingles (sometimes called "architectural" or "dimensional" shingles) and tab shingles.

Architectural Shingles (Laminate Shingles / Dimensional Shingles)

Laminate shingles, dimensional shingles and architectural shingles are all basically synonymous. They are thicker, layered shingles that can have the look of slate or wood shakes. They do not have slots and tabs, like the other main type of shingle, but rather have a strip laminated onto the base shingle giving them a textured appearance. Architectural shingles have become very popular due to their durability, great value and the breadth of colour and pattern options.

Tab Shingles

Tab shingles are the traditional style of shingles with tabs and slots that most people think of as shingles. They are manufactured in a single layer making them flatter and thinner than architectural (laminated / dimensional) shingles. Tab shingles are generally the least expensive type, but it’s important to note that architectural shingles having been falling in price in recent years.

The three-tab style is the most common, but there are also five-tab versions avaiable. Tab shingles are very versatile since and can be used on a roof slope as low as 2:12 when special application methods are applied. The Malarkey Alaskan tab shingle, in particular, performs well in low slope applications and in Calgary’s drastic weather extremes.


Metal Roofing

Metal roofing, although more expensive initially than shingles, has a much longer lifespan and offers many benefits. Advantages of metal include easy installation and it is ultra-light weight reducing the burden on roofing structures. Of course, metal roofing doesn't burn, making it very fire resistant. Metal is also a great sun reflector, keeping your home cooler in summer when we have those long, Calgary sunny days. You can find more benefits on our Metal Roofing Page.

Metal roofing can be steel, aluminum, copper, or alloy, and comes in a wide variety of colours, textures and shapes. Steel is the most commonly used material because of it’s durability and lower costs. Softer metals, like aluminum, aren’t recommended because they can weaken over time, particularly at joints, from the stresses of wind and winter contraction.

Metal is not the cheapest material but it is becoming more popular due to its long life expectancy.

Copper Roofing

The greenish tinted roofing of Ottawa’s Parliament buildings are made of copper. Over time, its surface acquires a greenish patina that can be very attractive. However, copper is extremely expensive, so it is not practical for most home owners.

Pre-finished steel

Pre-finished steel (galvanized steel with a heavy protective coating) is the most commonly installed metal roofing material. It is very strong, durable, lightweight and is available in many styles.

Pre-finished steel is used for the manufacture of both metal roofing tiles and panels. An underlay is mandatory beneath any metal roofing due to condensation, which regularly occurs on the underside of the panel.


Rubber Roofing

Rubber Roofing CalgaryThe durability, environmentally friendliness, and beauty of rubber have made it a popular roofing material over the last decade. The Euroshield rubber shingles that Tony William installs are made from 95% recycled materials, with as many as 1000 rubber tires used in the average residential roof. With long lasting durability, rubber is considered a permanent roofing solution. It is likely that a rubber roof will outlast the life of your home. Euroshield offers a transferrable limited lifetime warranty to on their rubber roofs.

Rubber shingles simulate the look of slate or shake, offering all the beauty without the maintenance. Rubber is extremely durable, long lasting, environmentally friendly and walkable. Rubber roofing is very quiet and offers extreme hail resistance.


Wood Roofing

The two most common wood roofing materials are cedar and pine and come in either shakes or shingles. Wood shingles and shakes differ in their texture. Wood shingles are cut by saw, so they have smooth flat surfaces. Wood shakes are split to produce a thicker, irregular surface that can look more natural.

Calgary Pine Shakes

In the late 1980s, the Alberta provincial government approved the use of untreated pine as a roofing material. Untreated pine was expected to have a 25 year lifespan, but the reality is that it deteriorated much faster. It was not until 1998 when pine shakes were removed from the building code as a roofing material in Alberta. If you still have a home with untreated pine shakes, it is certain that your roof needs to be replaced.

Cedar Roofing Grade

Number 2 Grade cedar shingles is the minimum requirement for the building code. However, Number 1 Grade is often required by warranties. Shakes are required to be Number 1 grade. Higher grade of wood will reduce warping and splitting as the wood ages.

Wood Treatments

All wood shingles and shakes should be treated to resist decay and fire. Anti-fungal agents and fire retardants are applied to extend the life of the wood and protect against fire.


Clay Tiles

Clay is one of the oldest roofing materials and in many countries around the world, remains the most commonly used. Clay tiles are heavy and thick, making them a good insulator against the sun. Clay is not used in colder climates like Calgary where freezing can crack the tiles.


Concrete Tiles

Concrete tiles have been used as a roof covering in Canada for many years. They look very similar to clay tiles and are applied the same way. Concrete tiles are much heavier and more expensive than asphalt shingles. They are also more labour intensive to install. Not all residential roofing structures can support the heavy weight of concrete tiles, so they are not widely used.


Slate Roofing

Slate roofing is a natural stone that is extremely durable, fireproof and very beautiful, but also heavy, expensive and difficult to install. Slate roofs can last for hundreds of years if installed correctly, but the weight makes them best suited for brick or concrete constructed buildings. Slate roofing is available in Calgary but it is rarely installed. Modern rubber or metal roofing materials offer a similar aesthetic and performance at a much lower cost.


The Most Important Roofing Features

Fire rating

Roofing systems are rated with a Class A, B, or C rating. Fire ratings are measured in two ways; resistance to fire from above the roof and fire exposure under the roof. It is not only the shingles, or other roofing material that is evaluated. Fire ratings will also be influenced by the roof sheathing below the surface roofing materials.

For non-combustible materials like metal, only the spread of the flame on top of the roof is measured. The maximum flame spread is 6 feet for a Class A roof, 8 feet for Class B, and 13 feet for Class C.

It’s important to note that thinner roofs will often have a better fire rating simply because there is less combustible material to burn. Thicker, more durable roofing will last much longer, but may have a lower fire rating due to the large mass of materials used.

In general, you’ll want to look for roofing with the highest fire rating of Class A. For example, Malarkey Laminated Architectural Shingles come with a Class A fire rating.

It’s important to note that some very high quality roofing materials may have lower ratings due to other factors like flame spread.

Here is some more information on roofing fire ratings.





With the exception of commercial and flat roof projects, we are currently quoting residential projects to commence in 2021. Thank you for your understanding.

There are two general types of roofing warranties offered, the manufacturer’s warranty to replace defective installation and the installation warranty offered by the roofing company. Warranties are only good as the company that provides them. Make sure you choose a reputable roofer, with a long established business so that you can rely on them to fulfill any potential warranty obligations.

Tony William Certified

At Tony William, we offer a 10 year installation warranty on all our roofing renovations so you can trust that your roof will last. Tony William has been doing business in Calgary since 2008 and has completed thousands of roofing jobs. You can trust that we honour our warranties. 

Manufacturer’s Warranty

Roofing manufacturers will provide warranties for the replacement of defective materials. Most warranties include full reimbursement for materials and installation for a limited time. Manufacturer’s warranties are up to 10 years for asphalt shingles and can be 50 years for composite slate and metal roofing. Be sure to inquire about the manufacturer’s warranty for the roofing material you select.

Prorated Warranties

Some manufacturer’s warranties are prorated which means the warranty value will decrease over time as your roof gets older. There may be a non-prorated period in the beginning and then a prorated period after that. The shingles Tony William uses are a 10-15 year non prorated warranty- and then a limited lifetime warranty after those years.

Limited Lifetime Warranties

After the initial warranty has expired, some roofing materials come with a limited lifetime warranty to cover material defects. For example, Malarkey offers a pro-rated limited lifetime warranty on it’s laminate and Alaskan 3-Tab shingles.

Other Manufacturer’s Warranties

Manufacturers offer additional warranties for more specific types of protection. The GAF and Malarkey shingles that Tony William installs are warrantied for winds up to 130 mph. Malarkey Scotch Guard protected shingles are warrantied against staining and discolouration for 20 years from the date of installation. Your Tony William roofing specialist will explain all the warranties for the products you are considering.

Installation Warranty

Manufacturers only guarantee the roof materials, they will not cover incorrect installation. Trust that Tony William Roofing & Exteriors will install your roof up to and surpassing manufacturer’s requirements. That is why we back all our roofs, with our own 10-year installation warranty. That will give you piece of mind knowing that your roof will last the test of time.

Lifespan of Roofing Materials

In addition to the warranty, the longevity or expected lifespan of your roof is an important consideration. It’s possible to save money up front by installing lower quality roofing materials, or going with a cut-rate roofing contractor, but you’ll very likely need to prematurely replace your roof or deal with damage from leaks and other problems. That expression, “you get what you pay for” is true in roofing as it is in most things. Make sure you research all the roofing contractors you are evaluating to choose a reputable company you can trust and one that will be there for the long term.

A new roof is a big investment. When deciding on your next roofing material, current costs are important, but also think about when your next replacement will be. Will you be replacing your roof in 10, 15, 20 or 50 years or more. What are those extra years of life worth to you today. A good roof is an investment that will not only protect your home for years to come, but also save you money.


Roof Pitch

The slope, angle or pitch of your roof will affect the materials and cost of replacing your roof. The pitch of a roof is calculated by the number of inches it rises vertically for every 12 inches it extends horizontally. For example a 6:12 slope has a vertical rise of 6” for every horizontal run of 12”.


Low Slope Roofs

Most roofing materials designed for for slopes above 4:12. On flatter roofs with low slopes, like 3:12, some materials do not shed water adequately and are more susceptible to wind damage. Your Tony William Roofing Specialist will inspect your roof and inform you of the options available

Steep Pitch Roofs

If your roof has a particularly steep slope, of 7:12 or more, installation costs are likely to be slightly higher. It is difficult to safely walk on very steep roofs, making installation more complicated. The good news is that steep roof slopes shed water more effectively and make it more difficult for wind to penetrate between shingles so a wide variety of roofing materials are available.



Flashing refers to the metal strips that seal the seams and joints of the roof. Roofs are most likely to leak where two sections of your roof connect like wall edges or chimneys so metal protection is added. It is important to keep your eavestrough free of debris like leaves, so that water can flow freely off of your roof. Otherwise, water can build up under the flashing, potentially damaging the roof base, causing leaks or lead to rust and deterioration of the flashing.



Roofing underlayment is the material that is put on top of the roof base or roof decking and below the shingles or top roofing material. There are three main reasons for using underlayment:

1. Water Barrier - to keep water from reaching the roof base.  
2. Separation Barrier - to keep roofing shingles chemical mixture from leaking onto the base roof materials. 
3. Heat and Sound Barrier - added insulation from external heat and sound. 

Underlayment is installed as a barrier against water, heat and wind penetration. Long lasting snow accumulation and water pools, caused by clogged eavestroughs or ice dams, can damage a roof if underlayment is not installed. With Calgary’s long, cold winters and snow fall, underlayment can extend the life of your roof. There are two major types of underlayment:

Tar Paper or Plain Asphalt Felt

Commonly referred to as tar paper, asphalt felt is a heavy fibre material saturated with asphalt. Asphalt felt comes in 15 to 30lbs weights, with 30lbs offering the greatest water resistance. It can be placed on the roof perimeter or it can cover the entire roof for extra protection. Asphalt is sticky to work with and slippery to walk on making it harder to install.

Synthetic Underlayment

Synthetic underlayment is made of polypropylene, fiberglass, polyethylene and polyester. It is lighter weight than asphalt felt, yet still offers a water resistant barrier for the roof sheathing. Synthetic underlayment generally has a much longer lifespan than asphalt underlayment as it is less susceptible to weather and other deterioration with age. Synthetic underlayment is generally more expensive, however it is more effective in preventing water penetration.


Ice Shield

An ice and water protector, also know as an ice shield, is a rubber sheet that is used at eavestroughs, valleys, penetrations, low slopes and where there is frequent water run off. It can look similar to asphalt or felt underlayment but it offers significantly improved protection against water and wind penetration.

The ice shield has a sticky backing that adheres directly to the roof sheathing. On asphalt based underlayment, nail holes and overlapping areas can still let water underneath, but the rubber material of the ice shield and the sticky adhesive forms a tight seal.

Ice shields can be used on the whole roof, but they are typical used on the perimeter and trouble prone spots like joints, skylights, chimneys or valleys.


Other Considerations with Your Roof Replacement

A new roof is not complete without soffit, fascia, eavestroughs and downspouts. All are needed to maintain the structural integrity of your roof in the future.


Fascia refers to the vertical boards which cap the end of rafters outside your home and are used to hold the eavestroughs or rain gutter. Fascia is an important structural element to your roof.


The finished surface below the rafters is called the soffit. Soffit is vented to allow adequate airflow into your attic. Tony William carries many different types of soffit in a variety of colours and styles. We'll help you pick the perfect accent to your new roof replacement. 


The purpose of eavestroughs is to collect run-off water from the roof and drain it away from your home’s foundation. It is important to regularly inspect and clean your eavestroughs to keep them free of debris. Clogged eavestroughs can lead to water build up and roofing damage.


Downpipes drain water from your eavestroughs and pour it away from from the foundation of your home. Tony William offers downpipes in a variety of colours and sizes to match your new eavestroughs.


Full Service Exterior Renovations

Tony William Roofing & Exteriors is a full service exterior renovation company. That means we do all types of exterior renovations including roofingsiding, windows, doors, decks, in a wide variety of materials, styles and combinations. Tony William has extensive experience with both commercial and residential roofing and siding. We pride ourselves on our custom roofing and siding projects. We do complex, multi-material exterior renovations that most other contractors don’t have the expertise or equipment for.

This is very important for two key reasons. First, most small, independent roofing contractors will only specialize in a limited range of materials. That means you’ll be presented with fewer roofing options, and might even be encouraged to install materials less than ideal for your requirements.

For example, a small roofer specializing in standard 3-tab roofing shingles, is unlikely to have the experience and expertise to install metal roofing or add kayu batu wood accents on your home. That roofer may not do eavestroughs, and may need to hire an outside contractor that ends up delaying the project.

The second benefit of hiring a full service company like Tony William is that we manage the entire process for you. Do you need a new front deck, eavestroughs and siding along with your custom metal roof and hardwood soffit? We do it all for you. There is no need to screen, hire and manage multiple independent contractors. Tony William is your one point of contact. Everything gets completed up to the high standards of our company. It starts with the friendly and knowledgeable roofing expert that will meet you and guide you through the process, right to the final cleanup and follow up after your exterior renovation is completed. We work hard to minimize disruptions to your family and make your major renovation project hassle free.

Choosing a Roofing Contractor

A new roof is a major investment. Quality roofing materials, along with professional installation will ensure your roof will last for many years. You want to make sure you choose the best roofing materials for your budget, and equally important, you want the best roofing contractor you can find.

At Tony William Roofing & Exteriors, we know you’ll be comparing us to other roofing companies. We do the exact same thing when we are making large purchases.

Find a roofing company you can trust. You don’t want to be charged for extra services and options that you don’t really need. Roofs are constructed in many shapes, sizes, slopes, and with many other variables. These variations make it important to choose a knowledgeable professional to advise on exactly what is needed without overcharging.You want a professional installation that follows manufacturer’s requirements so that material warranties will be honoured. Most importantly, you want an installation warranty backed by an established, reputable roofing company to ensure your roof is installed to last.

Consumer Protection Agencies – BBB

The Better Business Bureau (BBB) website lists any complaints that have been registered against registered roofing companies, and whether or not those complaints have been resolved. This is by no means an indication of the qualifications or quality of the company. Online reviews and customer recommendations should be researched as well.


A roofing contractor must be insured for your protection. There are two mandatory forms of insurance in Alberta; insurance offered by the Workers Compensation Board (WCB) to cover worker injury, and general liability insurance in case of damage resulting from work performed.

Personnel Policies

Tony William Roofing & Exteriors has a strict code of worker behaviour and ethics to ensure that all our roofers are courteous and attentive. Our workers are always completely professional and never engage in inappropriate behaviour.

Safety Control Programs

Roofing contractors are required to have a safety program. A Contractor should be able to produce a certificate as evidence that the course has been taken. Tony William Roofing & Exteriors has held the Alberta Construction Safety Association's COR (Certificate of Recognition) each year since 2012.

The Contract


A specification (spec) is a detailed description of the materials, the work required and any other details required to complete your roofing project. The specifications document will clearly outline exactly what to expect so there won’t be any surprises. Specifications are more common for larger commercial projects, than residential, but most reputable roofing companies will clearly explain all the work, materials and costs up front. This should be part of the contract you receive.


Always get multiple estimates. Costs and quality can vary a lot from one roofing company to the next. A general rule is to get a minimum of 3 estimates. Make sure you are getting estimates on the same type of roofing systems and the same quality of installation so that you are comparing “apples to apples”. Not all roofing companies are equal. Choose the company you know you can trust.


The contract should be clear and understandable, and include the complete specifications of the project. Once you sign the contract, it is a legally binding agreement so make sure you know exactly what you are getting and agree to the terms. The contract will clearly outline the costs and payment schedule. There should also be information on the roofing company’s installation warranty.

Questions to Ask Roofing Contractors

When evaluating Calgary roofing contractors, don’t be afraid to ask all the important questions about the company, material choices and installation techniques. Reputable contractors won’t be offended, it’s their job to answer questions to your satisfaction. If the company’s representative doesn’t understand technical details or doesn’t seem willing to answer your questions, the company might not be right for your roofing replacement.

  • How long have you been in business?
  • How many roofing projects has your company completed?
