What Sarnia Says
Reviews from real customers
"Jeff and his crew tore off and replaced our roof in two days. Site was spotless when they left. Best contractor experience we've had — and we've done a lot of renos."
"Lost a bunch of shingles in a windstorm on a Sunday. Jeff was here within a couple hours with a tarp and a quote. Insurance approved it without a fight."
"Went with standing seam metal. Jeff walked us through every option, no upsell pressure. Looks incredible and we're set for the next 50 years."
"Bilingual service was a huge plus for my parents. Jeff was patient, explained everything in French, and the repair has held up perfectly through two winters."
"Honest pricing, showed up when he said he would, did exactly what was quoted. Hard to find that combo these days."
