About Our Roofing Service in Guelph
Your roof is the most critical component of your home's weather envelope. D&D Exterior Finishing performs full roof replacements, repairs, and emergency services across Ontario — using quality asphalt shingles rated for the province's wind and snow loads. From minor repair after storm damage to complete tear-off and re-roofing, we deliver roofing that protects your home for decades.
Ontario Building Code & Climate Context: Ontario's climate creates specific roofing challenges. Ice dams — formed when warm attic air melts roof snow that refreezes at cold eaves — can force water under shingles and into the structure. Ontario Building Code requires ice and water shield membrane on all eaves and in valleys. Wind uplift is also a concern in open areas of Southern Ontario; shingles must be rated for the local design wind speed. D&D Exterior Finishing follows all OBC requirements and manufacturer specifications for shingle installation in Ontario.

Frequently Asked Questions — Roofing in Guelph
How long does a roof replacement take?
Most residential roof replacements are completed in 1–2 days. We work efficiently to minimize the time your home is exposed. Weather permitting, most jobs are done in a single full day.
What roofing shingles do you use?
We install architectural (laminated) asphalt shingles from reputable manufacturers including Owens Corning, IKO, and BP Canada. We recommend products with strong wind and algae-resistance ratings for Ontario.
Do I need a permit for a roof replacement in Ontario?
Most like-for-like roof replacements (same material, same pitch) do not require a permit in Ontario. Adding skylights or changing the roof structure requires a permit. We advise on your specific situation.
How do I know if I need a new roof or just a repair?
Signs you need a full replacement include shingles over 20 years old, widespread granule loss, multiple areas of missing or curling shingles, or evidence of widespread moisture damage in the attic. Isolated damage areas can often be repaired. D&D Exterior Finishing provides honest assessments.
What is the warranty on your roofing work?
D&D Exterior Finishing provides a 5-year workmanship warranty on all roofing installations. This covers labour defects. Manufacturer warranties on shingles typically range from 25 years to lifetime depending on the product selected.
