A flat roof, also referred to as a low-slope roof, is a system that combines durability with affordability. Having an angle of ~10° to avoid water build-up, the slight slope prevents leaks and collapses. Many commercial buildings are made with flat roofs because they’re modern, stylish, and practical. Flat roofs can be installed with a variety of materials, making them a versatile option for many different buildings, whether they’re residential or commercial. These roofing systems have a clean design, and they require little maintenance.


What are the advantages of flat roofs?

Since they cover a smaller surface area than sloped roofs, they require fewer materials, making them more cost-efficient. They also have more strength than pitched roofs due to their level surface, which means they can be walked on. Flat roofing provides space for a rooftop patio, solar panels, and/or a garden. 


What types of flat roofs are there? 

Various membranes and materials are used in the construction of flat roofing. We’ll go over some of the most common to give you a better idea of what you need: Single-ply membranes like TPO, PVC, and EPDM are cost-effective, easy to install, and will reduce your cooling costs due to their reflective properties. Modified bitumen roof systems are 2-ply and use an asphalt-based material. They are durable and have a good level of elasticity, which means they can withstand low temperatures. You may want built-up roofing, which uses layers of tar and gravel to create a thick and sturdy roof. It offers protection against water, is low-maintenance, and the alternating layers have the strength to withstand foot traffic. Each material comes at a different price point, so you should consult with a roofing contractor to find out which is the best fit for your residential or commercial building.


Why do buildings in Winnipeg have flat roofs?

If you’re a Winnipegger, you’re no stranger to the fierce winters that we experience in this city. A flat roof has the strength to stand up to piles of snow without caving in. Commercial businesses look refined and modern with a flat roof; they are clutter-free and efficient. 


What are some repairs that flat roofs need?

If standing water accumulates on the flat roof, it needs to be removed immediately to prevent a leak. Keep an eye on your roof after it rains to see if water builds up. The same goes for heavy snowfall in the winter - if your building has an excess of snow on top, it’s a good idea to shovel it off once in a while. A flat roof should be inspected twice a year to make sure it’s in top shape. If you need roofing services - that’s our specialty!

How long do they last?

The endurance of a roofing system is dependent on how well it’s taken care of - it also varies depending on the material used. Without proper installation and preventative maintenance, a flat roof may need a replacement sooner than you’d expect. A flat roof that’s regularly maintained and installed by experienced contractors can last up to 30 years.
