Our roofing systems are specifically engineered to withstand the demands of Alberta's climate, built for durability, longevity, and lasting performance.
We install wind and impact resistant shingles that provide reliable protection against moisture, extreme winds, heat, and ice, all while boosting your home's energy efficiency and curb appeal. Every job is completed with the right components and materials to ensure long-term protection, and to guarantee that your manufacturer's warranty remains fully intact.
Choosing the right roofing company is not a decision most homeowners take lightly, and for good reason. Your roof is what stands between your family and Calgary's harshest weather, from heavy snow loads and freeze-thaw cycles to hail storms and strong winds.
At Sunwest Roofing, we keep things simple: show up, do the job right, and treat every customer the way we would want to be treated.
Over the past decade, we have replaced more than 4,000 roofs across Calgary, and our reputation has been built one satisfied homeowner at a time.
We pay attention to the details, give honest recommendations, and see every project through from the first inspection to the final cleanup, leaving your home protected and your property exactly as we found it.
We stand firmly behind the quality of our work, offering a 10 year labour warranty alongside our 50 year shingle warranties. Our commitment to superior craftsmanship means you can trust that every installation is completed to the highest standard. When you invest in your roof with us, you are not just getting a durable, long-lasting result, you are getting the peace of mind that comes with knowing your home is protected for decades to come.
When it comes to addressing roofing issues, the right choice depends on the extent of the damage and the overall condition of your roof.
Repairs may be a suitable solution for localized damage on newer, structurally sound roofs with no underlying moisture concerns. However, when damage is widespread, shingles are aging, leaks are recurring, or repair costs are steadily mounting, a full replacement is often the more practical and cost-effective long-term decision.
Sunwest Roofing takes the time to walk homeowners through both options clearly and honestly, ensuring you have a thorough understanding of long-term costs, warranty coverage, and expected performance before committing to a solution that is right for your home.
Here are some signs that your roof may need replacing:
Most roofing systems have a lifespan of 15 to 25 years depending on the materials used and the climate they are exposed to.
If your roof is approaching or has surpassed this age, it is worth having it professionally assessed to determine whether a replacement is the smarter long-term investment
Alberta's unpredictable weather can take a serious toll on your roof, and storm or hail damage is not always visible to the untrained eye.
Even minor impact damage can compromise your shingles' protective layer, leaving your home vulnerable to leaks and further deterioration over time.
Damaged or deteriorating shingles are one of the most obvious signs that your roof is struggling to do its job.
Left unaddressed, these problem areas can allow moisture to penetrate the underlying structure, leading to far more costly damage down the line.
If leaks keep coming back despite previous repair attempts, it is a strong indication that the issue runs deeper than a simple fix can resolve.
Persistent water stains on your ceilings or walls are a warning sign that should never be ignored, as ongoing moisture damage can affect your home's structural integrity.
With over 4000+ installs, Sunwest Roofing has been providing reliable roofing services to Calgary homes since 2011. Fully licensed, insured, and backed by strong warranties, we combine craftsmanship with superior materials for results that last.
If your home currently has cedar shake roofing, converting to asphalt shingles is a smart move for durability and reduced maintenance. We handle the full process, removing the old shake and replacing it with modern shingles that look great and perform far better.
Class 4 shingles are the highest impact-rated shingles available, built to stand up to severe hail and extreme weather. They tend to last longer than standard shingles and can qualify you for insurance discounts, making the upgrade well worth considering for many Calgary homeowners.
Steep roofs are one of the most common roof styles in residential construction, and they require a specific skill set to install safely and correctly. Our crews are experienced working at height and on sharp pitches, ensuring every shingle is laid properly and every detail is done right.
Class 3 shingles are a reliable, cost-effective option for homeowners who want solid protection without the premium price tag. They offer moderate impact resistance and perform well in most weather conditions, making them a popular choice across Calgary neighbourhoods.
Acreage properties often feature larger, more complex roof systems that require additional planning and crew coordination. Whether it’s a sprawling farmhouse or a custom rural home, we bring the same standards and quality workmanship out to you no matter where you’re located.
We work on a range of commercial roofing projects, from low slope flat systems to larger multi-unit buildings. We understand the complexity that comes with commercial work and delivers the same honest pricing and quality results our residential clients expect.

If you live in Calgary, you already know that hail season is no joke. Choosing the right shingle impact rating for your home can be the difference between a roof that holds up and one that doesn't.
Class 3 shingles are a solid, budget-friendly option that handles most of what Alberta weather throws at them. Class 4 shingles are built for the worst of it, offering the highest impact resistance available along with better long-term value and potential insurance savings.
Not sure which one makes sense for your home? That's what we're here to help you figure out.

When it comes to roofing materials, we're selective on purpose. Sunwest Roofing exclusively installs Malarkey and Owens Corning Duration® shingles because we've seen firsthand how they perform through Alberta's harshest seasons. These aren't just well-marketed products, they're shingles that genuinely hold up, and are backed by manufacturers who actually stand behind their warranties when it counts.
The Duration® shingle is built around Owens Corning’s proprietary SureNail® fastening technology, which means a stronger hold, better wind resistance, and a shingle that stays put when Alberta weather gets serious. On top of that, Duration® shingles are engineered for long-term granule retention, so your roof keeps its performance and curb appeal years down the road.
Malarkey shingles are purpose-built for impact and wind resistance, making them one of the smartest choices for Calgary homeowners who deal with hail season every year. Select lines even feature smog-reducing granules, adding an environmental benefit on top of an already impressive package of durability, weather protection, and solid warranty coverage.

Metal strip installed along the edges of your roof that directs water away from the fascia and into the gutters, preventing rot and water damage at one of the roof’s most vulnerable points.
Secondary moisture barrier between your decking and shingles, offering superior protection against wind-driven rain and tear-through compared to traditional felt, keeping your home dry if the outer layer is ever compromised.
Self-adhering waterproof membrane installed at eaves, valleys, and other high-risk areas to prevent water infiltration caused by ice dams and heavy rain, which is especially critical in colder climates like ours.
Seals the most water-intensive areas of your roof where two slopes meet, channeling heavy runoff away from the seams and preventing leaks that can quickly lead to rotted decking and interior damage.
This maintains a balanced airflow between your attic’s intake and exhaust, regulating temperature and moisture levels that, if left unchecked, can cause premature shingle aging, ice dams, mold growth, and structural deterioration.
Finished row of shingles installed along the peak of your roof that seals the ridge vent opening from the elements while giving the roof a clean, polished look — making it both a functional and aesthetic cornerstone of a complete roofing system.
We start with a free, no obligation roof inspection and provide a clear, written estimate with options and line items so you can make an informed decision.
Once we have your approval and desired material choice, we enter your project into the schedule and send you the estimated install date and other updates via email.
You will receive another set of emails notifying you of material delivery, and the day before the install, so you have time to make parking arrangements and other considerations.
Our experienced professionals complete your install exactly as specified. If there are any unforeseen weather delays, we will take all necessary precautions and return at a better time.
After installation, we perform a thorough cleanup of the work area. A final walkthrough ensures the job meets our standards and yours.
Your project is backed by a workmanship warranty, along with applicable manufacturer warranties. Our team is always available to answer any questions or concerns that may arise later.

We used sunwest to complete our hail repairs after last years hail storm. Couldn’t be happier with the end result as they even helped us get 2500$ back from our insurance company for upgrading to the class 4 shingles

Look for missing, curling, or cracked shingles, granules collecting in your gutters, dark stains or sagging on your roof deck, and water stains on your ceilings or attic. If your roof is approaching 20–25 years old, it’s worth having a professional inspection even if there are no obvious signs of damage.
We carry only the best roofing materials such as Owens Corning Duration and Malarkey Vista & Legacy.
The shingles we carry will last 25=40 years. Proper ventilation, installation quality, and regular maintenance all play a significant role in how long your roof holds up.
Most residential roof replacements can be completed in a single day, though larger or more complex roofs may take 2–3 days. We always clean up thoroughly before we leave so your property is left in great shape.
We work carefully to minimize noise and always complete a thorough cleanup once the job is finished.
