Trust in Our Experience

With 125 years of experience, Sanderson Roofing is Ottawa’s flat roof repair specialist. We can install, repair, and replace any type of flat roof, including:


Built-up roofs

A built-up roof or BUR is one of the oldest roofing systems. It is one of the most common roofing materials used on low-slope roofs, such as tar, gravel, coal tar and asphalt. Built-up roofs are incredibly durable, offering enhanced protection against external forces like winds, etc. Built-up roofs offer outstanding waterproofing and protection against UV rays, are low-maintenance and are energy-efficient. So if you are looking for a stress-free roofing solution, then built-up roofs are the right choice!


Modified bitumen (roofs)

A modified bitumen roofing system is composed primarily of polymer-modified bitumen reinforced with one or more plies of fabric, such as polyester, fibreglass, or a combination of both. Factory surfacing is composed of mineral granules. The bitumen provides primary waterproofing protection, while the reinforcement adds strength, puncture resistance, and overall system integrity. The granule coating offers UV protection.


Single-ply roofs: PVC, TPO and EPDM

A single-ply roof is a broadsheet that is meant for low-slope roofs. It doesn’t require asphalt installation. In addition, it comes with prefabricated detailing accessories, making the installation process easy. Some of the most commonly used single-ply membranes are PVC, TPO and EPDM. PVC single-ply roof membrane is used in a low sloped and flat roofing system. Similarly, TPO as a single-ply roof membrane comprises a single synthetic layer used to cover flat roofs. Both PVC and TPO are durable and wind-resistant.

EPDM, on the other hand, consists of a synthetic rubber compound that makes it flexible. It is also quick and easy to install, and long-lasting.
