Top Asphalt Shingle Brands Preferred by Ontario Roofing Experts
At T Dot Roofers, we’ve been helping Ontario homeowners with roof replacements and repairs since 2018. Over the years, we’ve gained firsthand expertise in identifying which shingle brands deliver durability, style, and value—knowledge that’s crucial for homeowners navigating roofing decisions.
While modern asphalt shingles typically last 25–30 years, older roofs using organic materials may degrade in as little as 12–18 years. Even entry-level shingles today boast multi-decade lifespans and robust warranties. Below, we highlight the top brands we install across Ontario, including two favorites that balance quality and affordability.
