Storm & Wind Damage

Toronto weather can be unpredictable, and your roof often takes the brunt of it. High winds, hail, ice, and driving rain can all cause sudden damage that compromises your home’s protection. As an experienced roofer serving the GTA, Ontario Downspout Service responds quickly to storm-related issues, helping homeowners assess the damage and get repairs underway before things get worse.

Whether you’re dealing with lifted shingles, punctures from hail, or ice-related cracking and leaks, we know how to spot even subtle signs of damage. Wind damage might not always be obvious right away, but left unchecked, it can lead to major structural issues. Our goal is to restore your roof’s integrity with smart, efficient repairs—so you can get back to normal without added stress.

Ice Dam Repair

Ice dams are a common winter headache for Toronto homeowners, often forming when melting snow refreezes at the edge of your roof. This creates a barrier that traps water, leading to leaks, damaged shingles, and even interior water damage. As a trusted roof repair company in Toronto, Ontario Downspout Service specializes in ice dam repair that tackles both the symptoms and the root causes.

Our team provides emergency repairs when ice dams cause immediate issues, as well as preventative solutions to help minimize the risk in future winters. We safely remove ice buildup, restore proper drainage, and assess your attic insulation and ventilation to stop the cycle from repeating. If you’re dealing with an ice dam—or want to avoid the next one—we’re here with the tools and expertise to help protect your home all winter long.
