Frequently Asked Questions
Not sure what your flat roof needs? We hear these questions all the time. If you don’t see your question here, give us a call.
How long does a flat roof last in Calgary?
With proper installation and maintenance, most flat roofs last 20 to 30 years. EPDM and TPO systems typically reach 25+ years, while SBS modified bitumen performs exceptionally well through Calgary’s freeze-thaw cycles. Lifespan depends on materials, workmanship and how well the roof is maintained.
What’s the best flat roofing material for Calgary’s climate?
It depends on your building and budget. EPDM rubber handles temperature extremes and is cost-effective. SBS modified bitumen stays flexible in cold weather, making it ideal for Alberta winters. TPO reflects heat and offers energy savings. We install all three and can recommend the best fit for your property.
How do I know if my roof needs repair or replacement?
If you have isolated leaks or minor membrane damage, roof repair usually makes sense. Signs that point to roof replacement include recurring leaks, widespread cracking, sagging areas and a roof over 20 years old. We provide free assessments and honest recommendations.
Do you offer roofing services for other roofing types, including sloped roofs?
Yes, we offer roofing services for sloped roofs. We primarily work with asphalt shingle roofs and provide both repair and replacement services.
What areas do you service for flat roofing in Calgary?
We provide flat roofing services across the greater Calgary area, including Airdrie, Cochrane, Okotoks, Strathmore, Langdon and Chestermere.
Why is my roof leaking?
Common causes of roof leaks include failed seams, damaged flashing, punctures and poor drainage. Calgary’s freeze-thaw cycles also stress membranes over time. Our roof repair team can locate the source and fix it properly.
Is flat roof replacement worth it or should I just keep repairing?
If you’re calling for flat roof repairs every year, replacement is usually the smarter investment. A new EPDM, SBS or TPO system can last 20 to 30 years with minimal maintenance. We’ll give you an honest assessment of repair vs. replacement.
What flat roofing systems do you install in Calgary?
We install EPDM rubber roofing, SBS modified bitumen and TPO membrane systems. Each has different strengths for Calgary’s climate. EPDM is durable and affordable. SBS handles extreme cold. TPO offers energy efficiency. We help you choose the right one.
How much does roof repair or installation cost in Calgary?
Cost depends on roof size, materials and scope of work. We provide free on-site assessments and detailed quotes with no hidden fees. Contact us for a roofing estimate tailored to your property.
Can you help with emergency roof repairs in Calgary?
Yes. We respond quickly to stop active leaks and protect your property from further damage. Call us for emergency roof repair across the greater Calgary area.
Why should I hire a flat roof specialist instead of a general roofer?
Flat roofs require different techniques than sloped roofs. Drainage, membrane selection and seam welding all require specialized knowledge. We focus exclusively on flat roofing in Calgary, which means better results and fewer callbacks.
What’s included in a flat roof installation?
Our flat roof installations include substrate preparation, insulation, membrane application, seam sealing and proper flashing details. We install EPDM, SBS and TPO systems and stand behind every project with manufacturer and workmanship warranties.
Do you provide free roofing estimates in Calgary?
Yes. We offer free on-site assessments for flat roof repair, replacement and installation across Calgary and surrounding areas. No pressure, just honest advice.
