Choosing a roofing contractor comes down to personal choice. You want someone with the resources to provide exemplary service when you need it, but also someone small enough to care about you. Luckily for you, Magnum Commercial fits the bill on both accounts. The Ottawa Region has come to rely on us for quality repairs and replacements at competetive prices. We’ll do whatever it takes to convince you that we’re the right choice.

Our History

Magnum Commercial was established in 2020 when Steven Crossthwaite the owner of Magnum Roofing (est. 1981) entered into a partnership with Pat O‘Neill owner of PLS Custom Roofing (est. 2010). Pat brings with him 20+ years of knowledge and unsurpassed skill in the flat roofing industry. He has mastered the application of a multitude of different products enabling him to take on a magnitude of flat roofing work. These include almost every roof system available from single-ply flat roofs to steel shingles. Some of the most common applications are 2 ply modified bitumen, built-up insulated roof systems, cold applied 2 ply, cold liquid applied re-enforced 3 ply with gravel topcoat, cold applied single ply (TPO, EPDM, SARNIFELD, DEC TEC), cold-applied roof refurbishing for existing modified bitumen roofs, and re-sloping existing flat roofs. Magnum Roofing brings its industry-leading reputation for quality workmanship using top-of-the-line products at a reasonable price point.
