Question Answers

How does roof cleaning in Ontario help prevent flashing corrosion?

In Ontario, debris, moss, and algae can trap moisture against your roof's metal flashing, accelerating corrosion. Our professional roof cleaning safely removes these elements, allowing the flashing to dry properly and extending its lifespan. This preventative maintenance is crucial for protecting the vulnerable seams around chimneys and vents from the leaks that corrosion causes.

Why do skylights in our area seem to leak so often, and how do you fix them?

Ontario's temperature swings and sun exposure can cause skylight seals and flashing to degrade faster. A leak often starts small at the sealant or where the flashing meets the roof. Our repair service involves a thorough inspection to find the exact failure point, then we meticulously replace seals, re-flash the unit, and ensure a watertight integration with your roof shingles to stop the leak for good.

Can you repair a leaking skylight without replacing the entire roof?

Absolutely. In most cases, a skylight leak is isolated to the unit itself or the flashing directly around it. Our expert technicians can perform a targeted repair that addresses the specific leak source—whether it's cracked sealant, damaged flashing, or a compromised shingle layer—without the need for a full roof replacement, saving you significant time and money.
