A Guide to Commercial Flat Roof Repair

A Guide to Commercial Flat Roof Repair

April 5, 2023

Many different factors can cause a flat roof repair, but one constant is a water leak that causes a roof leak repair is where the problems begin. If you need a roof leak repair in Markham, a roof repair in Mississauga, a roof repair in Oakville or a flat roof repair in Etobicoke, the services of a professional roofing company will be necessary. Damage can be caused to your commercial inventory or equipment when a roof leak demands a company that offers a flat roof repair near me. Safety is always job one in any occupation or economic sector, but roof repairs can often be cost-prohibitive if the leak isn’t that bad.

We at Integrity Roofers have heard many concerns expressed by our customers when their roofing systems start to degrade. Rest assured, when you contract our company to eliminate problems, you have chosen one of the best roofing companies in the Greater Toronto Area. We provide the right roofing solution – every problem is unique, based on the roofing system and the problem besetting the roofing system – at the right price for commercial business owners.

What are Common Flat Roof Problems?

The commonality of roofing problems can be categorized into a few different scenarios. Still, the bottom line is your roofing system faces challenges based on other variables that equate to roof repairs. We have compiled a short list of the most common afflictions a roofing system suffers from and some solutions to keep a solid roof overhead.

  1. Roof leaks
  2. Low spots or ponding water
  3. Material warping
  4. Seam gaps
  5. Accumulated debris
  6. Water damage inside your building

When you observe any or all of these conditions, your first call should be to your roofing company. If you don’t have a roofing company caring for your roofing system with twice-a-year inspections, this might be the time to initiate such an arrangement.

What is the Best Product for Flat Roof Repair?

When you contact us at Integrity Roofers, we want you to know that we work with the top roofing supply companies in the business using top-flight products that have an industry reputation for longevity and quality that is unsurpassed. The nature of the roof repair will dictate the product used for the repair, and the type of flat roof you have will also significantly influence what products will be required. Built-up roofing systems require different materials than TPO or EPDM roofing systems – a professional roofing company knows the difference and their experience and expertise will provide a successful conclusion to your roofing problems. Here is a list of products we use and how they offset roofing problems.


Acrylic is an incredibly durable substance that requires a primer layer, a fabric reinforcement for strength, and two coats of acrylic.


Silicone is a roof coating providing excellent energy savings and convenience.


Polyurethane is known to work against ponding water and is another layer of insulation for your roof.


Butyl coatings work to reflect UV rays, and it helps your roof as a vapour barrier.

How Can I Stay on Top of My Flat Roof Repair?

Preventive maintenance and seasonal maintenance are the only way to go. You have your car in for winter maintenance; why not your roof? As we mentioned above, regular roof inspections in the spring and fall take of minor problems before they grow into large ones, and the inspections tell where future issues will come from. Executing maintenance plans is a cost-effective way of extending the life cycle of your roof. Many commercial roofing systems will fail in a decade if not maintained. If you purchased a roof with a 20-year lifecycle, get your money’s worth with a maintenance plan that will save you money in the long run. Spending just over a dime per square foot for your roofing system on maintenance can add a decade’s worth of life to your roofing system.

How Do I Know If My Roof Needs a Repair or Replacement?

Several factors affect roof repair and roof replacement. It comes down to age. Say you bought a 20-year roofing system, and you’re at the 15-year mark and roof defects are showing up due to weather and old age. Pouring money into the roofing system might not be cost-effective in light of the fact that the roof will be replaced in a few short years anyway. Take the repair money and use it for a replacement to save money on additional repairs that the roof would require before the end of the life cycle of the roof.

Signs of Heat Damage on Your Roof

Missing or Damaged Shingles

When the heat pounds down on your asphalt shingles, they will dehydrate and lose flexibility. Once the shingles have become deprived of moisture, they become brittle and start to crack. Then water leaks into the cracks, which is not a good situation to be in. Once your shingles are brittle, they are susceptible to high winds that can take them right off the roof, and you have exposed areas where water can soak through.

Shrinking and Blistering

When unseasonably high temperatures beat down on your roof shingles, they will shrink and bubble causing blisters that create thin spots on the shingles. As the shingles shrink, they cover less area and water always seems to find the gaps where the shingles don’t cover. Once the blisters have eroded to the next layer, the inner surface of your roof is exposed to the elements – like rain – and the water permeates the surface.

Mould Damage

You can expect standing water on your roof if your gutters are blocked. In the hot weather, water is the perfect petri dish for mould to grow and cause roof rot topside. Heat and humidity working in concert will spur mildew growth, and if the growth is close to a roof vent, the mildew can end up in the air return system, exposing employees to respiratory infections.

How to Protect Your Roof from Summer Heat

There are a couple of low-cost solutions to keep your roof cool in the summer. The first one, solar panels, creates a couple of other wins for the building owner. The first advantage is generating electricity from solar panels – utility cost savings. The second is the panels are a form of insulation, reducing heat radiation into the building. That, in turn, reduces the stress on your HVAC system and lowers the cooling costs of the building. The other solution is planting a rooftop garden as a means of protection. The UV radiation from the sun can’t penetrate the garden soil adding another layer of protection for your roof and HVAC system.
