Leaks, missing shingles, flashing, storm damage.
L&B Roofers handles residential and commercial roof repairs across the Greater Toronto Area. Our team diagnoses the real cause of the problem — not just the visible symptom — and repairs it to hold up through the next Toronto winter.
Visual and physical inspection of shingles, flashing, valleys, penetrations, vents, and attic-side signs of moisture. You get a plain-English explanation of what we found.
We trace active leaks to their source (which is rarely where the water shows up inside) and repair flashing, seams, seals, and membrane rather than papering over the symptom.
Replacement of missing, cracked, or lifted asphalt shingles. Re-flashing of chimneys, skylights, sidewalls, and pipe boots using compatible materials.
Patch repairs on TPO, modified bitumen, and built-up flat roof systems — heat-welded or torched to bond correctly with the existing membrane.
After a Toronto windstorm or hailstorm, we assess and repair blown-off shingles, lifted ridge caps, damaged vents, and displaced flashing.
Most residential roof repairs are completed in a single visit. Larger repairs or complex flat roof work may take longer — we'll give you a firm timeline with your written estimate.
We aim to schedule non-emergency roof repair visits within a few business days. Active leaks and storm damage are prioritized — see our emergency roof repair service for same-day response.
In most cases, yes. If the underlying deck is sound and the majority of the roof is in good condition, a targeted repair is the right call. If the roof is near the end of its service life, we'll tell you honestly and quote a replacement as an option.
