What Are Your Flat Roof Replacement Options?

When does a commercial or industrial flat roof need to be replaced?

Depending on the condition of your flat roof, a replacement may need to be in store. When the roof is old, has multiple leaks and other issues and repair costs add up to equate to the cost of replacement, it is better to invest in a new flat roof altogether. Flat roof replacement on commercial and industrial buildings may sometimes also be the only option depending on whether the problem can be detected in the roofing system.

Below are your options for commercial and industrial flat roof replacements:

Metal Flat Roof – This type of roof has its appeal due to its durability and its lifespan that can last up to over three decades. Nowadays, most metal flat roofs are made of aluminum, which is non-combustible and helps lower a/c costs by redirecting heat from the sun’s rays away from the building.

Single Ply EPDM Flat Roof – EPDM flat roofs are affordable, flexible, durable and take little time to install, making them a favourite in the flat roofing industry.

Double Ply Modified Bitumen – A modified bitumen flat roof is a good eco-friendly option due to its reflective properties. Similar to an asphalt roof, the installation process involves rolling the material onto the roof and blowtorching it to create a strong seal.

Four Ply Built-Up Roof – This roof type has been around for a long time, consisting of gravel and hot tar. These materials add extra weight to the roof system, meaning there may be need for structural reinforcement prior to installation. It is an inexpensive fire-retardant option.

Single Ply PVC and TPO – This is a great option due to its impenetrability to water and resistance to pooling of water. This roof system is applied in rolls and has to be installed expertly to prevent gaps at the seams. The material is lightweight and therefore lower in cost.
