Roof Repair Services in North York

Dominion Roofing has served North York for over 100 years – since 1922. That’s more than a century of local expertise you can trust on your roof.

When your roof leaks, you don’t want a contractor driving in from across the GTA –  you want the roof repair North York crew based ten minutes away. Our repair teams dispatch daily from our Cartwright Avenue headquarters to homes across Willowdale, Don Mills, York Mills, Downsview, Bathurst Manor, and Lawrence Manor.

Some of the services we offer include:

  • Roof Leak Repair. We trace leaks to their true source – not just the ceiling stain – and repair the underlying flashing, valley, or membrane failure so the fix lasts.
  • Shingle Repair & Replacement. Missing, curled, or wind-lifted shingles are matched and replaced before water reaches the deck. Common after North York’s freeze-thaw winters and summer windstorms.
  • Flashing, Chimney & Skylight Repair. Roof leaks often develop around chimneys, vents, and skylights. We reseal and reflash these areas to help keep water out.
  • Flat Roof Repair. As the GTA’s longest-standing flat roof specialists, we repair blistered, ponding, or split flat roof membranes on North York homes and businesses.
  • Eavestrough & Soffit Repairs. Overflowing eavestroughs rot fascia and back water under shingles – we repair the full drainage path, not just the visible damage.
  • Full Assessment. Whether you’re buying a new property or simply want to assess the health of the roof in your home, let us give you a full inspection. Our knowledgeable expert staff can give you a full accounting of your roof’s health so that you can budget for any needed maintenance, repairs, or replacements.
  • Roof Repair. Our repair services include replacing missing shingles, fixing minor leaks, repairing damage caused by storms or other aspects of nature, skylight repairs, gutters and soffit repairs.
  • Gutter Cleaning. A healthy roof is a clean roof. We offer Gutter cleaning services to keep your gutters properly maintained and avoid costly damage due to lack of maintenance.
  • Tear Out and Re-Roof. Sometimes a simple repair is not the optimal solution for your roof. If it’s time for a complete tear out, we can remove and replace the existing roof and replace it with a quality roof to last for years to come.
  • New Construction. Contractors and homeowners in the North York area trust Dominion for the highest quality in new construction roofing.

Frequently Asked Questions

Reroofing should not be done when the structure over which the replacement shingles will be laid is not strong enough. If there are large holes, lots of rotten shingles, wood, or other materials in the original roof, they will not provide an adequately robust foundation for the new shingles. The Dominion Roofing team assesses each job individually to make sure that the right method is used to make a roof good again.

Reroofing can be a good idea when the old roof structure has not begun to rot. Laying new shingles over the top of the old ones means that the repair can be done faster and that fewer materials are needed. As a result, reroofing is often cheaper than installing a full replacement. Contact us today and we will inspect your roof and let you know which option is best for you as well as provide you with a quote.

Before choosing a new roof, call in Dominion Roofing and let us explain all of the options to you. This will enable you to make an informed decision. So, that the new roof you choose will look good, protect your property from the elements and do so for many years to come.

Dominion Roofing provides free, no-obligation quotes. Call 416-789-0601 and we'll assess your roof before you commit to anything.

Because our headquarters is right on Cartwright Avenue, we can typically reach any North York home the same day for emergencies. We offer 24/7 support: our crew will secure and tarp the leak immediately, then complete the permanent repair once conditions allow.

Yes, flat roofs are Dominion's founding specialty. We repair blistering, ponding, splits, and membrane failures on flat roofs across North York's homes, additions, and commercial buildings, and we've been doing it since 1922.

You can stay in your house while the roof is being replaced, but it is usually better if you move out. Replacing a roof is a noisy and dusty process. It is also potentially dangerous to be around while it is being done, especially if you have children or pets.

Yes, it is possible for you to extend the service life of your roof. Regular maintenance (cleaning, inspections, restorations, etc.) can greatly increase your roof’s service life. It is also a good idea to properly maintain your attic to prevent excessive moisture from causing damages to your roof.

Significantly. Annual inspections and maintenance – clearing eavestroughs, resealing flashing, replacing individual worn shingles – catch small issues before water gets in. Our Roof Tune-Up maintenance program is designed exactly for this and typically pays for itself by preventing a single emergency repair.

If damage is isolated - a few missing shingles, a single leak point, worn flashing – a repair is almost always the smarter spend. If your roof is near the end of its lifespan (20–25 years for asphalt shingles) or has widespread deterioration, replacement saves money long-term. Our inspection gives you an honest assessment either way; with over 100 years in business, we never sell a replacement where a repair will do.

Watch for water stains on ceilings, missing or curled shingles, granules collecting in eavestroughs, daylight visible in the attic, moss or algae growth, and sagging rooflines. In North York's climate, also check for ice dam damage along eaves after winter.
