Roof Replacement in London, ON
Your roof is the first line of defence against Ontario weather, and it ties into everything below it — soffit, fascia, and eavestrough. We handle asphalt shingle replacement: tear-off, deck inspection, ice-and-water shield, new underlayment, flashing, and shingles. Because we work on the whole exterior, the roof, roofline, and drainage get done as one coordinated job — not three separate trades pointing at each other. Permitted where required and installed by licensed roofing crews.
What's included
- Tear-off and deck inspection — we don't shingle over hidden problems
- Ice-and-water shield at eaves and valleys for winter protection
- Coordinated with soffit, fascia, and eavestrough work
- Full cleanup and magnetic nail sweep on completion
- Manufacturer shingle warranties plus written workmanship guarantee
- One point of contact for the whole exterior, roof included
Roofing We Install
A range of roofing options to suit your home and budget.
Asphalt Shingle Replacement
Full tear-off and re-roof with architectural or three-tab shingles, including deck inspection and rotted-sheathing replacement where needed.
Flashing & Valleys
Step flashing, valley metal, and penetration boots — the spots where most roofs actually fail — replaced and sealed correctly.
Ice & Water Shield
Self-adhering membrane at eaves and valleys to protect against ice damming through Ontario winters.
Roof Ventilation
Balanced intake and exhaust venting to extend shingle life and reduce attic moisture — coordinated with your soffit.
Roofline Coordination
Roof, soffit, fascia, and eavestrough handled together so the whole roofline drains and finishes as one job.
