This roof repair project in Toronto involved reversing significant structural and moisture damage caused by animal intrusion—primarily raccoons. The homeowner initially reported a leak, but upon inspection, we found over 10 different entry points created by wildlife.

Animals had removed shingles from weakened roof sections and chewed through the wood decking to gain access inside. One of the most common weak spots is plastic roof vents, which are easy for animals to chew from underneath. In most cases, only a close visual inspection reveals the actual entry points.

Once inside, animals often create further damage as they attempt to escape—chewing wires, tearing insulation, and making new exit holes. These activities not only compromise the integrity of the roof but also lead to long-term moisture infiltration and leaks.

🔨 What We Did:

• Identified and exposed all hidden entry points

• Replaced damaged shingles and plywood decking

• Installed a thin steel barrier beneath high-risk areas for added protection

• Sealed all roof vents and edges to prevent re-entry

• Performed a full water-tightness check post-repair

This repair ensured the home was leak-free and animal-proof moving forward. If left unresolved, even minor animal damage can lead to expensive roof replacements and interior damage.
