Everything you need to know before hiring a Toronto roofing or masonry contractor.
Key signs include: shingles that are curling, cracking, buckling, or missing; granule loss in the gutters; daylight visible through the attic; water stains on ceilings or walls; and a roof that is 20–25+ years old. A free inspection by our Toronto roofing team will give you a clear answer and honest recommendation — repair vs. full replacement.
EPDM (rubber membrane) is flexible, durable, and excellent in cold GTA winters. TPO is a white single-ply membrane that reflects UV rays — great for energy efficiency. Torch-on (modified bitumen) is a two-ply heat-applied system popular for its proven track record. We'll recommend the best system for your building type, slope, and budget during your free estimate.
Most residential roof replacements in Toronto and the GTA are completed in 1–2 days. Larger homes, complex roof shapes, or multi-layer tear-offs may take 2–3 days. We work efficiently and clean up completely at the end of each day so your home is never left exposed overnight without reason.
Tuckpointing (also called repointing) is the process of removing deteriorated mortar joints from brickwork and filling them with fresh mortar. You need it when mortar joints appear cracked, crumbling, recessed, or discoloured — these are all signs that water is entering your wall structure. Left unaddressed, failed mortar leads to spalling brick, interior leaks, and costly structural repairs.
Yes. Ontario Pro Construction maintains active WSIB (Workplace Safety and Insurance Board) coverage and full liability insurance. We are happy to provide WSIB clearance certificates and proof of insurance to any homeowner or property manager before work begins. This protects you from any potential liability during the project.
