Tear-off, deck inspection, new roof installed to manufacturer spec.
When a roof is at the end of its life, patching stops making sense. L&B Roofers installs new residential and commercial roof systems across the GTA with complete tear-off, deck inspection, and materials chosen for Ontario weather.
We remove old roofing down to the deck rather than laying new shingles over old — the only way to inspect the deck and install a warranty-eligible system.
Every sheet of plywood or OSB is walked and checked. Soft, rotted, or damaged decking is replaced before any new roofing goes down.
Ice-and-water membrane at eaves, valleys, and penetrations (Ontario code minimum plus what the roof actually needs), synthetic underlayment across the field.
Asphalt architectural shingles for pitched roofs, or TPO / modified bitumen for flat roofs — installed to the manufacturer's specification so the material warranty is valid.
New flashing at all penetrations, updated ridge/soffit ventilation where needed, magnetic sweep of the property, and haul-away of all debris.
Most residential replacements are completed in a short timeframe — typically a few days depending on size, roof type, and weather. Larger homes, complex rooflines, and full flat roof systems take longer, and we'll give you a firm schedule with your written estimate.
Service life depends heavily on the material, the installation, ventilation, and maintenance. A properly installed architectural asphalt shingle roof and quality flat roof systems like TPO and modified bitumen are all designed to last decades when installed to spec and maintained.
We don't recommend it and we don't do it as a standard offer. Layovers hide deck problems, shorten the new roof's life, and often void the manufacturer's material warranty. Tear-off is the right long-term choice.
No. Most homeowners go about their day. We just need clear driveway access and a plan for any vehicles that need to move.
You get both the manufacturer's material warranty (varies by product) and our workmanship warranty on the installation.
