Allison Home Improvements | General Contractors & Roofing in Gwynn Oak, MD 21207

Yes, absolutely. When we build a deck or home addition, we carefully plan the roof integration and drainage. A poorly attached structure can disrupt your main roof's water flow, contributing to gutter overflow. Our team ensures proper flashing, grading, and downspout placement to direct water away from your foundation, protecting both your new project and your existing home from common local storm leaks.

It's possible. In many Gwynn Oak homes, persistent roof leaks or gutter overflow can saturate the ground and siding near a deck's ledger board (where it attaches to the house). This constant moisture can rot the wood and compromise the connection. When we perform deck repair, we inspect the adjacent house structure and roofing for contributing issues, ensuring our fix is comprehensive and lasts.

Protection starts with the roof. For any addition in Gwynn Oak, we design a roofing system that seamlessly ties into your existing structure with reinforced flashing and ice & water shield—critical for preventing storm leaks at the valley where roofs meet. We also size and position gutters specifically for the new roof pitch to handle heavy rain and prevent overflow, safeguarding your investment from day one.
