John Martin roofing and renovations

A new roof is one of the largest single investments a homeowner will make — and a bad installation can leak for years before anyone notices the damage. A licensed roofing contractor in Douro-Dummer handles roof inspections, leak repair, full roof replacement, gutter installation, skylight fitting, and storm damage assessment. When hiring, verify the roofer holds a state roofing licence (required in most states for jobs over $500), carries both liability insurance and workers’ comp (roofing has one of the highest workplace injury rates in construction), and offers a manufacturer-backed warranty on materials plus a separate workmanship warranty on installation. Beware of storm-chasers who knock on your door after hail — many are out-of-state contractors who vanish when warranty claims arise. Fieseros lists roofing businesses serving Douro-Dummer, with verification status visible on each profile so you can quickly filter for providers whose identity, business, insurance, and licensing have been independently checked. In Ontario, the cold climate and prevalence of basement foundations mean roofing work must account for snow load and ice-dam prevention.
