Flat Roofing Types We Install

We offer multiple flat roofing solutions designed for Alberta’s challenging climate. Each system provides distinct advantages depending on your building’s needs and budget. Our team installs the industry’s best-performing materials. So, whether you need energy efficiency or maximum durability, we have the perfect roofing option for your property.

TPO Roofing

TPO roofing delivers excellent energy efficiency and cost-effectiveness for your property. This single-ply membrane reflects UV rays and reduces cooling costs significantly. TPO systems resist punctures and weathering exceptionally well. Installation is straightforward and reliable for most commercial and residential buildings.

EPDM (Rubber) Roofing

EPDM rubber roofing provides proven durability in extreme weather conditions. This material flexes with temperature changes, preventing cracks and failures. Our crew installs EPDM systems with precision sealing techniques and expertise. Your roof withstands Calgary’s harsh winters and dry summers reliably for many years.

Modified Bitumen Roofing

Modified bitumen (SBS) combines asphalt with rubber polymers for superior performance. This roofing type offers excellent adhesion and weather resistance. Our technicians torch-apply the material for complete membrane coverage and durability. It’s one of the most affordable flat roof options available today for residential properties.

Built-Up Roofing (BUR)

Built-up roofing with tar and gravel provides multi-layer protection for your property. Each layer strengthens the overall system and extends lifespan considerably. We install BUR systems with precision, ensuring proper drainage and water management. This traditional choice remains popular for many commercial buildings.

Benefits of Flat Roofing

Flat roofs offer significant advantages for modern buildings and residences. They maximize usable space, reduce costs, and provide clean aesthetics. Additionally, flat roofing systems require less material than sloped alternatives. So, you’ll see savings across installation, maintenance, and energy expenses. A properly installed flat roofing in Calgary protects your home every season. Also, many property owners appreciate the contemporary look and functionality.

Energy Efficient and Cost-Effective

Our flat roofing systems reduce heating and cooling costs substantially. Light-colored membranes reflect sunlight, keeping interiors cooler during hot seasons. Because TPO and PVC materials offer superior insulation properties, your energy bills drop noticeably. Additionally, installation costs are typically lower than traditional sloped roofing solutions.

Modern Aesthetics and Clean Lines

Flat roofs create a sleek, contemporary appearance for any building. This modern design suits both residential homes and commercial structures perfectly. We ensure clean lines and professional finishes on every roofing project. So, your property gains visual appeal alongside practical functionality and performance.

Additional Usable Space

Flat roofs allow you to use rooftop areas for equipment, gardens, or patios. This extra space increases your property's functionality and real estate value significantly. Our installation methods ensure proper drainage so water damage never occurs. Because of this design advantage, many property owners choose flat roofing systems over sloped alternatives.

Easy Maintenance and Accessibility

Flat roofs are easier to inspect and maintain than sloped alternatives. Our technicians can walk safely on your roof during maintenance visits. We perform thorough inspections to identify potential issues before they cause damage. Also, routine maintenance extends your roof's lifespan considerably.

 Trustindex verifies that the original source of the review is Google. I hired Diamond Cut for my roof replacement .  They are just finishing up now.  Steve was great to work with, his crew is beyond anything I’ve worked with before.  They did an excellent job but they come with a bonus.   My property was immaculate when they were working on the roof and was cleaner when they left.  I work for a builder and see a lot of crappy workmanship along with debris everywhere.  You won’t be disappointed with Steve and his crew.

 Trustindex verifies that the original source of the review is Google. I had an excellent experience with DiamondCut Roofing. They had the most reasonable estimate for the roofing and sidings damage caused due to hailstorm. The price they quoted was almost half compared to others. They did not charge for repair inspection and the ICC siding color evalution report. Stephen is very knowledgeable as no other vendor had advised me that the siding color might have been discontinued from market so better get the color report before starting the work. He not only provided high quality service but took the ownership to finish the work without any hassle. I will highly recommend DiamondCut Roofing for genuine service for roofing and siding replacement

 Trustindex verifies that the original source of the review is Google. Diamondcut Roofing (Steve)  recently replaced our cedar shakes with Class 4 shingles, and the entire experience exceeded our expectations. From the start, their pricing was fair and accurate compared to the many other quotes we received, and their professionalism and organization really stood out.
With a 35-year-old roof, we expected to run into surprises, but Diamondcut was able to mitigate every issue along the way. They kept the pricing reasonable and transparent, so we never once felt caught off guard.
The installation was completed to a very high standard, with excellent attention to detail, and the cleanup afterward was just as thorough. We were also able to upgrade some of the vents to 360 vents, and even with that addition, the total cost still came in lower than competitors.
We’re so glad we took the time to do our due diligence, because finding Diamondcut meant finding the best roofer for the job. Highly recommended! plus our neighbors were all very impressed with their workmanship.

 Trustindex verifies that the original source of the review is Google. Excellent company. Steve did wonderful work (all my himself!) on our little house and his invoice matched his quote. He was fast, clean, and very professional. Very good pricing also. He was competitive with all the annoying door-to-door roofing sales guys whom I pray will now stop knocking on my door now that we have a nice new roof. Thanks Steve!

Roof Preparation and Cleanup

Proper surface preparation is essential for successful installation. We remove old materials, debris, and damaged sections carefully. Our crew cleans the substrate thoroughly to ensure proper adhesion. Additionally, we protect your landscaping and surrounding areas during this phase.

Substrate and Underlayment

We inspect the roof deck and repair any damaged wood or insulation. Then, we install high-quality underlayment for additional protection against water intrusion. Proper slope and drainage are established during this critical step. Because of this foundation work, your roofing system performs optimally.

Membrane Installation

We install your selected flat roofing membrane using professional techniques. Our technicians ensure complete coverage and proper sealing of all seams. Whether torch-applied, adhered, or mechanically fastened, installation meets manufacturer specifications exactly. So, your system meets all warranty requirements.

Flat Roofing Cost in Calgary

DiamondCut Roofing offers competitive pricing on all flat roofing solutions in Calgary and surrounding areas. Most residential installations range from $5,000 to $15,000 depending on size and materials. Commercial projects typically cost more due to complexity and scale. So, understanding these cost drivers helps you budget accurately for your project.

What Affects the Price

Material selection significantly impacts your total project cost. TPO and EPDM typically cost less than PVC or modified bitumen options. Additionally, roof size, accessibility, and existing damage increase labor expenses. We provide detailed estimates so you understand every cost component thoroughly.

Flat Roofing vs. Sloped Roofing

Flat Roofing

Sloped Roofing

Flat roofing works exceptionally well for Calgary’s climate and modern buildings. Our team helps you choose the best option for your specific needs. Good flat roofing in Calgary keeps your property protected every single season. Each system offers distinct advantages depending on your priorities.

Flat Roof Leaks and Repairs

Leaks can develop even with quality flat roofing systems over time. Water intrusion causes interior damage, mold growth, and structural problems rapidly. We identify leak sources precisely and repair them permanently. So, addressing leaks immediately protects your entire building investment.

Common Leak Points

Seams and flashing typically fail first on flat roofs. Ponding water creates pressure that breaks down membranes gradually. Penetrations (vents, skylights, mechanical units) require careful waterproofing. Additionally, old caulking and sealants deteriorate over time, allowing water entry.

Professional Repair Services

Our team patches small leaks and performs complete membrane replacements. We use quality materials matching your existing roofing system. Each repair receives the same attention as new installation work. Because we address root causes, leaks don't return repeatedly.

Emergency Flat Roof Repair

Storm damage, sudden leaks, and unexpected failures require immediate attention. We provide emergency roofing services 24/7 for Calgary properties. Our rapid response prevents water damage and additional building damage. Call us immediately when roofing emergencies occur.

We respond quickly to emergency situations protecting your property. Storm damage, leaks, and failures demand professional attention immediately. Contact our team now for emergency flat roof repair services.

How to Maintain a Flat Roof

Regular maintenance extends your flat roof’s lifespan significantly. Preventive care identifies problems before they become expensive issues. Our team recommends professional inspections at least annually. Because proper maintenance protects your investment, it saves money long-term.

Clear Debris and Ponding Water

Remove leaves, branches, and other debris regularly from your roof. Ponding water should drain within 48 hours after rainfall. Standing water creates additional weight and membrane damage over time. Also, drainage problems require professional assessment and correction.

Check for Blistering and Cracks

Blistering indicates moisture trapped within the membrane layers. Small cracks can expand rapidly, creating serious leaks. We repair these issues before they cause extensive water damage. So, prompt attention prevents costly building damage later.

Inspect Seams and Flashing

Check seams and flashing twice yearly for separation or damage. Caulking should remain flexible and complete without cracks. Professional sealants maintain waterproof integrity against weather exposure. Because seams are critical leak points, they need regular attention.

Professional Annual Inspections

Schedule professional inspections every spring and fall. Our technicians identify potential issues invisible to untrained eyes. We document conditions and recommend preventive maintenance measures. Additionally, professional inspections help maintain manufacturer warranty coverage.
