Flat Roof Repairs in Calgary for Every Type of Flat Roof
How Our Repair Process Works
We do not patch and run. Instead, every repair follows the same steps:
- Find the Source
First, we trace the leak or damage back to where it starts and check the surrounding areas, so there is no second surprise. - Clear Quote
Then you get a written quote that explains the problem, the repair method and the price before work starts. - Proper Repair
Finally, our crew uses materials and methods approved by the manufacturer, so the repair matches your existing roof system.
Common Flat Roof Problems We Fix
Calgary weather is hard on flat roofs. In particular, hail, chinook freeze-thaw cycles and heavy wet snow cause most of the damage we see, including:
- Roof leaks and water getting into the building
- Blisters, splits and cracks in the membrane
- Open seams and loose flashings
- Ponding water and blocked drains
- Punctures from foot traffic or rooftop equipment
- Hail and wind damage
- Worn parapets and roof-to-wall transitions

Types of Flat Roof Damage
Every roof gets damaged eventually, and flat roofs are no exception. However, a lot of damage can be avoided with regular maintenance. For example, our seasonal inspections find and fix problems before they turn into leaks. Other damage, such as a hailstorm or a wind event, comes without warning.
Repairs fall into three groups. Here is what to expect with each one.
1. Active Leaks and Storm Damage
You have a roofing emergency when water is coming into the building or part of the roof is missing, peeled back or punctured. In that case, it is important to act quickly to protect the building.
Common causes include:
- Fire
- High or sustained winds
- Large hail or wind-blown debris
- Heavy rain, wet snow or fast snowmelt
There is never a good time for a roof emergency. So call the Calgary team at 1-888-4-ROOFER. Phones are answered 24/7, and we will book a crew visit during working hours as soon as possible.
2. Urgent Repairs
Some damage is serious but not an emergency yet. Often it has been building slowly, while most of the roof is still protecting the building.
Because these problems are less dramatic, they are easy to miss. Watch for these signs:
- Leaks or stains
- Drafts
- Damp air
- Uneven temperatures
- Birds or pests getting in
- Standing water on the roof
- Changes in the roof surface
If you notice any of them, call us and we will find the cause.
3. Scheduled Repairs and Maintenance
Early damage is usually found during regular inspections. Fixing it right away, therefore, saves time and money.
Our crews look for early signs such as:
- UV wear
- Damage from foot traffic
- Impacts and hail bruising
- Weak patches
- Damaged plies or layers
Whether it is an active leak, urgent damage or normal wear, we can help.
How We Handle Flat Roof Repairs in Calgary
Roof problems are stressful, so we keep the process simple. Every repair starts at the source of the problem. Then we document it with photos and a written quote, so you know the scope and cost ahead of time. During the work, we keep you updated and send before and after photos.
Warranty terms for repairs are set out in your repair quote, so you know exactly what is covered before we start.
Flat Roof Systems We Repair
We install, maintain and repair flat roofs across Calgary and area, following recognized industry practice, including guidance from the National Roofing Contractors Association. Whether it is an active leak or preventive work, we repair all of the following flat roof systems.
SBS MODIFIED BITUMEN (STYRENE BUTADIENE STYRENE) ROOFS
SBS modified bitumen roofs are multi-ply and very tough. When they do fail, it is usually at laps, flashings or hail-bruised areas.
We repair SBS with compatible membrane and proper heat-welded or cold-applied details, so the repair lasts as long as the roof around it.
EPDM (ETHYLENE PROPYLENE DIENE MONOMER) ROOFS
EPDM rubber roofs usually leak at seams, flashings and around equipment. In addition, punctures from foot traffic are common.
We clean and prime the membrane and install compatible EPDM patches and flashing so the repair bonds properly.
PVC (POLYVINYL CHLORIDE) ROOFS
PVC roofs are repaired by heat-welding new PVC membrane to the existing roof. As a result, a properly welded repair becomes part of the roof.
We also check seams and penetrations nearby, since one open weld often means others are close behind.
TPO (THERMOPLASTIC POLYOLEFIN) ROOFS
TPO roofs are repaired by heat-welding compatible TPO membrane over the damaged area. Older TPO may need cleaning and preparation first so the weld holds.
Hail damage, open seams and punctures are the most common TPO repairs we do in Calgary.
TAR AND GRAVEL (BUILT-UP) ROOFS
Tar and gravel roofs can often be repaired by removing the gravel, rebuilding the damaged plies and resurfacing the area.
However, when the roof has reached the end of its life, we will tell you whether a repair is still worth the money.

Flat Roof Repairs in Calgary: Frequently Asked Questions
Common questions about repairing flat roofs in Calgary.
What should I do if my flat roof is leaking right now?
Call 1-888-4-ROOFER. Phones are answered 24/7. We will help you limit the damage, such as moving valuables and catching water, and a crew visit is scheduled during working hours.
How much does a flat roof repair cost?
It depends on the cause, the size of the damaged area and the roof system. We quote every repair in writing before work starts. If we need to investigate a leak first, that investigation is a paid service and we quote the fee before we book.
Is a repair warranty included?
Warranty terms for repairs are set out in your repair quote, so you know what is covered before we start.
Can hail damage on a flat roof be repaired?
Usually, yes. We document the hail damage with photos, which helps with insurance, and then repair or replace the damaged areas.
When should I replace instead of repair?
If leaks keep coming back, the insulation is wet in several areas or the roof is near the end of its life, replacement is often the better spend. We will tell you honestly which makes sense.
