This cedar roof repair project in Forest Hill, Toronto, required a high level of craftsmanship and roofing expertise. The home featured a custom-built drainage channel surrounding the cedar roof, which had started to show signs of age and deterioration. Our client reached out after noticing minor water pooling and concerns about long-term performance.

Our roofing team inspected the entire roof structure, focusing on drainage, flashing, and the integrity of the cedar shingles. It was clear that the old channel system was no longer effective, and worse, several original installation flaws posed risks for future leaks.

Custom Drain Channel Removal Without Siding Damage

The most complex part of this project was the careful removal of the drain channel while ensuring the home’s beautiful cedar siding remained untouched. In Forest Hill, homes often have unique architecture and high-end finishes, so preserving the exterior was non-negotiable.

We used specialized hand tools and protective materials to remove the existing drain system without damaging the woodwork. Every shingle and flashing point around the parapet and roof edges was documented and safely restored.

Detecting and Repairing Cedar Roof Installation Defects

While the drain channel was being removed, we uncovered multiple installation defects beneath the cedar shingles. These included improper underlayment placement, insufficient shingle overlap, and weakened roof-to-wall flashing.

Our cedar roofing experts corrected these issues by:

• Reinforcing critical seams and valleys

• Installing new waterproof underlayment

• Realigning mislaid cedar shingles

• Reflashing all affected roof-to-wall transition points

These proactive repairs ensured that any potential future leaks were eliminated before they could cause internal water damage.

Final Results – Leak-Free & Siding Fully Preserved

By the end of the project, our client had a fully functional, aesthetically preserved cedar roof with no risk of future leaks. The siding was untouched, the roofline looked seamless, and the new flashing blended perfectly with the original materials.

The homeowner was thrilled with the result — noting our professionalism, cleanliness, and attention to detail.
