Most roofers rush the job to move on to the next one. We do the opposite. Every project starts with a thorough inspection, proper flashing, and full deck prep before a single shingle goes down.
From older homes in established Toronto neighbourhoods to new builds across the GTA and Durham Region — flat roofs, steep-slopes, dormers, valleys — if it's overhead, we've done it. We use Owens Corning and CertainTeed products because they're engineered to handle Ontario's brutal freeze-thaw cycles.
Residential and light commercial. Any size. The standard never changes.
Full tear-off and replacement using premium architectural shingles. Most projects completed in a single day.

Optima Roofing & Construction was built on one simple idea: homeowners deserve a roofing company that shows up when it says it will, does what it promises, and stands behind its work.
We're a family-run crew — not a franchise, not a call centre. When you call us, you speak to the people who'll be on your roof. We've been protecting homes across Toronto and the Greater Toronto Area since 2001, and every job we take gets the same level of care.

Most residential roof replacements in the Greater Toronto Area range from $8,000 to $20,000+ depending on the size, pitch, materials, and number of layers being removed. We provide free, no-obligation quotes with a full line-item breakdown — no hidden fees.
Most standard residential roofs are completed in a single day. Larger homes or complex roof lines (multiple dormers, steep pitches, skylights) may take two days. We'll give you a realistic timeline before we start — and we stick to it.
No — most homeowners go about their day. We'll confirm access requirements beforehand, take before-and-after photos, and walk you through the finished work when you're back. All we need is access to the exterior and a safe distance from the work area for pets and children.
We back every full replacement with a 10-year workmanship warranty, plus the manufacturer's product warranty on qualifying shingles. All repairs carry a 2-year warranty. Both warranties are transferable to the next owner if you sell your home.
Absolutely. We have experience working directly with all major Canadian insurance carriers. We can help document storm or hail damage, prepare the scope of work, and communicate with your adjuster to make the claims process as smooth as possible.
