What We Build. What We Protect.
From new installs to storm damage repairs, Sina's Roofing & Repair delivers commercial-grade workmanship on every residential and commercial job in Richmond Hill and the GTA.
Roof Replacement
When patching no longer cuts it, we tear off and rebuild your roof from the deck up. We use premium asphalt shingles, proper underlayment, and sealed flashing — installed to last 25+ years in Ontario winters.
Roof Repair & Storm Damage
Leaks, missing shingles, ice damming — we diagnose fast and fix it right. Emergency repair service available so water damage doesn't compound into a bigger bill.
Flat Roof Systems
TPO, modified bitumen, and torch-down flat roofing for low-slope residential additions, garages, and commercial buildings. Watertight seams, proper drainage, and a clean finish every time.
Eavestrough & Soffit
Gutters that overflow or soffits that sag undermine your whole roofline. We install, repair, and replace seamless eavestrough systems and ventilated soffits to keep moisture where it belongs — out.
Skylights & Flashing
Most roof leaks trace back to bad flashing around skylights, chimneys, or valleys. We re-flash and seal these vulnerable points with metal step flashing and proper counter-flashing — no caulk-only shortcuts.
Roof Inspection & Maintenance
A professional inspection catches small problems before they become major repairs. We deliver a written assessment with photos so you know exactly what your roof needs — and what it doesn't — before spending a dollar.
Transparent Pricing. No Surprises.

Common Questions Before You Call
We hear the same concerns from Richmond Hill homeowners every season. Here are straight answers — no fluff, no upsell pressure.
If your roof is under 15 years old and the damage is localized, a repair usually makes sense. If shingles are curling across the whole surface, granules are in your gutters, or the deck is soft in multiple spots, replacement is the smarter investment. We'll give you an honest assessment on-site — never push replacement when a repair will do the job.
