What Can Damage Your Flat Roof?

Poor Drainage and Roof Ponding

Roof ponding is one of the most common problems associated with flat roofs. Ponding occurs when water collects on the roof and doesn’t drain properly. This can cause the roof to sag, which can lead to leaks and other serious damage.

UV Damage

One of the biggest issues for flat roofs is UV damage. The sun’s ultraviolet rays can cause the roofing materials to break down, which can lead to leaks and other problems.

Snow and Ice

Flat roofs are also susceptible to snow and ice damage. If the roof isn’t properly insulated, snow and ice can melt and refreeze, which can cause the roof to leak.

Wind Damage

Wind can also cause damage to a flat roof if it wasn’t installed properly. If the wind is strong enough, it can lift the roofing material and cause it to tear or come loose. This can lead to serious leaks and additional damage.

Get Your Flat Roof Fixed

If you have a flat roof, it’s important to get any damage fixed as soon as possible. Ignoring damage can lead to bigger problems later on. Getting your roof coated can help prevent future damage and save you money in the long run. Contact us today for a free quote.

Flat Roof Replacement

If your flat roof is damaged beyond repair, or if it’s simply reached the end of its life, you’ll need to replace it. Our team at George Kent Home Improvements has extensive experience with flat roof replacement. We’ll select the right materials and install them correctly the first time.

The Different Types of Flat Roofs

The different materials used for flat roofs in Mississauga come in a wide range of options, depending on your needs and budget. Some examples include:

Single-Layer Membrane Flat Roof

Single-ply roofs use wide width sheeting designed for low slope roofs. They have far fewer seams than asphaltic rolled roof systems and don’t require dangerous torches or hot asphalt for installation.

Built-up Roof (BUR)

BUR Roofing includes multiple layers of protection to keep your building watertight. These systems come with guarantees or warranties of up to 20 years, and have been used for over 100 years.

Modified Bitumen

Modified bitumen is a type of roofing that is similar to the BUR system. It is made of asphalt combined with rubber or plastic, then reinforced with fibreglass to create a waterproof membrane.

Our Lifetime Roofing Warranty

At George Kent, we are proud to offer industry-leading lifetime warranties on materials and labour for our roofing installations — and our installations are not prorated. Additionally, your warranty is transferable to future homeowners and backed by the manufacturer (GAF).

Our warranties set us apart in an industry where typical roofing warranties are closer to five years or less. If you’re unhappy with your roof at any point after it has been installed, get in touch and we will be happy to resolve the problem.

We recently hired George Kent through Lowe's to remove our old insulation install new insulation in our attic and we are very pleased with the results. The crew was very respectful and professional; they were timely, cleaned-up after themselves and were very diligent. Our attic was in particular rough shape having had a pest issue in the past. The crew made sure EVERYTHING was removed prior to the new insulation being added. The crew really went above and beyond to explain everything that they were doing, to invite us to have a look for ourselves and they even added a few extras as an added-value. Refreshing to see that professionalism still exists these days

Great service! First impressions from Rasool were great, he was really knowledgeable about the roofs and insulation. He showed me every piece that went into my roof and answered all my questions with patience. The wait time they gave me was accurate and they have the best quality roofing. My roof looks great, I recommend them.

Modified bitumen is the cheapest commercial flat roofing system. While the lifespan of modified bitumen is shorter than other roofing systems, with regular maintenance you can maximize your investment.

What is the lifespan of a flat roof?

The materials used in a flat roof’s construction largely determines its lifespan. For example, a multi-layer built-up roof made of waterproofing, tar and gravel can last 15-20 years.

Do flat roofs require additional maintenance?

Flat roofs generally require more maintenance than sloped roofs, due to the accumulation of leaves and debris collecting on them.
