Those dark streaks are often a type of algae common in our humid climate. While not always an immediate structural threat, they can degrade shingles over time. We recommend a professional cleaning with specialized, roof-safe solutions. More importantly, we can install zinc or copper strips at the roof ridge—when it rains, tiny particles wash down and inhibit future algae growth, providing a long-term solution for your home.

Flashing seals the critical joints around chimneys, vents, and valleys—areas most vulnerable to leaks. Schenectady's freeze-thaw cycles and precipitation can cause metal flashing to corrode prematurely. We inspect for pitting and rust, then carefully remove the damaged sections. We replace them with new, high-grade metal flashing, sealed with professional-grade caulk or mastic to create a watertight barrier that will withstand our local weather for years to come.

In many cases, localized repairs are perfectly effective, especially for issues like isolated flashing failure or storm damage to a specific area. We'll conduct a thorough, honest inspection of your entire roof system. If the majority of the roof is sound and the problem is contained, we'll recommend a precise repair. We'll only advise a full replacement if it's necessary for the long-term protection of your Schenectady home, ensuring you get the most value from your investment.
