Maryland Home Exteriors | Roofing Services in Towson, MD 21286

During a full roof installation or replacement, we meticulously address the flashing—the metal pieces around chimneys, vents, and valleys that are prone to corrosion in our humid climate. We remove all old, corroded flashing and install new, high-quality materials with proper sealing techniques. This proactive approach during a new install is the most effective way to prevent the leaks and water damage that often start at failed flashing points on Towson homes.

Absolutely. In many Towson homes, damaged or corroded roof flashing can lead to water running down behind the siding, causing rot, mold, and insulation damage out of sight. When we perform a siding replacement, we conduct a thorough inspection of the underlying structure and sheathing. If we find water damage from roof-related issues, we repair it before installing your new siding. This ensures your home's exterior system works together as a complete, watertight shield.

Those dark streaks are Gloeocapsa magma algae, which thrives in our humid environment and can slowly degrade roofing granules. While gentle cleaning can be a temporary solution, the most permanent fix is often incorporated during a roof replacement. We offer algae-resistant shingles, which have copper granules that inhibit future growth. Choosing these during a roof replacement with Maryland Home Exteriors is a smart, long-term investment to keep your Towson roof looking cleaner and functioning better for years to come.
