Do I need a building permit to replace my roof in Oshawa?

For a straight like for like reshingling where nothing structural changes, the City of Oshawa generally does not require a building permit. You do need one if the work changes the roof structure, alters the roof line, or involves replacing sheathing over a significant area.

How quickly can you get to Oshawa for an emergency leak?

Most Oshawa addresses are about twenty minutes from our service base, so active leaks are usually same day or next day for an emergency tarp, with the permanent repair scheduled straight after.

Why do Oshawa homes get ice dams so badly?

Proximity to Lake Ontario means more freeze and thaw cycles than areas further inland, and each cycle rebuilds the ice ridge along the eaves. The fix is ice and water shield membrane along the eaves, correct attic insulation depth, and enough intake and exhaust ventilation to keep the deck cold.

Can you install a roof in Oshawa during winter?

Yes. Asphalt shingles need warmth to seal their adhesive strip, so in cold weather we hand seal where required and the shingles finish sealing when temperatures rise in spring. Emergency repairs happen year round.

How long does a roof replacement take in Oshawa?

Most Oshawa homes are finished in one to two days once we start. Larger or steeper roofs, multiple layers to remove, or significant deck repair can push it to three.

Tony explained what caused the leak and he rectified the issue. Also, Tony followed up a few weeks later just to check if everything was ok.

 Trustindex verifies that the original source of the review is Google. A week ago my roof was leaking and I went to find in Google who has the best review since we are new in Ajax and I found Metro roofing has the best one . I called Tony and right away he came to my house and see the issue and discussed what need to be done with fair pricing. He will not recommend extra work that has no value in your roof. He is very honest. I definitely recommend him.

 Trustindex verifies that the original source of the review is Google. Recently got our roof done by Tony and his crew. Got a few quotes and he was competitive but what won us over is that he was the only one that went on our roof after we told him about our leak issue, and he confirmed the issues prior to giving us a quote. Very professional and responsive. Job was done right and on time !

Over 40 Years Right Here in Durham Region

Metro Roofing is a roofing contractor in Oshawa serving homeowners, landlords and property managers across Durham Region. Our crews repair, replace and maintain asphalt shingle, metal and flat roofs throughout the city, from the older streets around downtown and Lakeview to the newer subdivisions north of Taunton Road. We work out of Ajax, which puts most Oshawa addresses about twenty minutes from our yard. That matters when you have water coming through a ceiling and you need someone on the roof this week rather than next month. Every roof we quote in Oshawa gets an onsite inspection first. We photograph what we find, explain what is actually failing, and give you a written price that separates what needs doing now from what can reasonably wait a season. No pressure and no vague verbal numbers.

Our Roofing Services in Oshawa Include

We have been on roofs across Durham Region since the 1980s, and Oshawa throws a particular mix at us: lake driven freeze and thaw along the south end, wide open wind exposure below the 401, and a housing stock that ranges from 1920s brick near downtown to subdivisions barely twenty years old up past Taunton. We carry the materials and the crews for all of it, from a single flashing repair to a full tear off and rebuild.

Your Oshawa Home Deserves a Roof Built Right the First Time

Most Oshawa homeowners call us at one of two moments: a leak has just appeared, or the roof has quietly hit the twenty year mark and they want to know how long is left. Both are worth an inspection. A leak caught early is usually a repair rather than a replacement, and knowing you have three good years left is worth as much as knowing you have none.

Ice damming along the eaves

Cold air off the lake combined with repeated freezing and thawing through January and February builds ridges of ice along the bottom edge of the roof. Meltwater backs up behind that ridge, finds its way under the shingles, and shows up as a stain on a bedroom ceiling in March. The shingles are usually not the problem. The real cause is almost always attic insulation and ventilation letting warm household air heat the underside of the deck. We check the attic before we quote, because replacing shingles without fixing airflow just buys you one more winter.

Wind uplift on exposed streets

Homes south of Highway 401 and anywhere with an open exposure toward the lake take steady wind loading. Over time this lifts and loosens shingle tabs, especially along ridges, hips and rakes. Once the seal strip lets go, the next storm takes the shingle with it.

Aging housing stock in south and central Oshawa

A large share of homes around downtown, Lakeview and the older streets near the former General Motors works were built between the 1920s and the 1960s. On these roofs we regularly find board sheathing with wide gaps, two or even three layers of old shingles, and original flashing that has simply rusted through. These jobs need a full tear off and often some deck repair, so pricing them from the street is guesswork.

Newer subdivisions reaching replacement age

Taunton, Kedron, Windfields and Samac filled in through the late 1990s and 2000s with builder grade three tab shingles rated for roughly twenty years. A lot of those roofs are now due. If your home is in this group and you are seeing granule loss in the eavestroughs or shingles that look curled at the corners, you are close.
