Roofing FAQs
Do you really beat any competitor quote?
Yes. Bring us a valid written quote from any licensed Ontario roofer for the same scope of work and we will beat it in writing. There is no haggling and no catch.
What types of roofing do you work on?
Ontario Roof Masters handles asphalt shingle roofs, flat and low-slope roofs, and all related repairs including leak diagnosis, storm damage, flashing, skylights, and plumbing vents. Both repairs and full installations are core services.
How do I know if I need a roof repair or a full replacement?
A roof under fifteen years old with localized damage is almost always a repair. Widespread granule loss, multiple leaks, sagging, or curling shingles across the whole roof usually means a full installation is the better investment. We give you an honest recommendation after an on-site inspection.
How fast can you respond to an active leak?
We offer same-day response for active leaks and storm damage in most cases, with priority scheduling so we can stop the water before it causes interior damage.
Are you licensed and insured?
Yes. Ontario Roof Masters is fully licensed and insured, and every repair and installation is backed by a workmanship warranty.
Do seniors get a discount?
Yes. Homeowners aged 60 and over save an extra 10% on qualifying roof repair and installation work. Just let us know when you request your estimate.
Do you offer free quotes?
Yes. All estimates are free, on-site, and no-obligation. We will give you an upfront, written price before any work begins, and beat any valid competitor quote you already have.
