Those black streaks are actually a type of algae that thrives in our humid climate. While it doesn't always cause immediate structural damage, it can degrade roofing materials over time. We recommend a professional soft wash cleaning to safely remove the stains without damaging your shingles. More importantly, we can install zinc or copper strips along your roof ridge. When it rains, trace amounts of metal wash down, creating an environment that prevents algae from returning, providing a long-term solution common in our area.

This is a very common concern in Richmond Hill due to our weather patterns. Our process starts with a thorough inspection to locate the source of the leak. We then carefully remove the affected shingles and underlayment to expose the roof deck (plywood or planks). We assess all wood for soft spots, moisture, and rot. Any compromised decking is completely cut out and replaced with new, treated wood to ensure a solid base. We never just patch over rot, as it will continue to spread and compromise your home's structure. Our repair restores full integrity.

Absolutely. When we install a new roof for a Richmond Hill home, we build in preventative measures. We use high-quality, algae-resistant shingles that have built-in granules to inhibit growth. We install new, waterproof synthetic underlayment for superior deck protection against ice and water. We also ensure maximum attic ventilation, which is crucial in our climate to reduce moisture buildup that leads to rot. By addressing the root causes—moisture and organic growth—with premium materials and expert installation, we give you a roof designed to withstand local challenges for decades.
