G & O Roofing | Roofing Services in Norcross, GA 30071

In Norcross, roof valley leaks are often caused by worn or damaged flashing, compromised underlayment, or debris buildup from our frequent storms. At G & O Roofing, we start with a detailed inspection to pinpoint the exact failure point. Our repair typically involves carefully removing old materials, installing new, high-grade valley flashing, and sealing it according to manufacturer specifications to ensure a watertight seal that can handle our local weather.

Chimney flashing leaks are common here due to thermal expansion and contraction, which can crack old sealant and loosen metal flashings over time. The best solution depends on the extent of the damage. For minor issues, a professional repair with new sealants may suffice. However, if the flashing is corroded or improperly installed, a complete replacement using step flashing integrated with the roof shingles is the more reliable, long-term fix we recommend to prevent recurring leaks.

Absolutely. Properly installed and maintained gutters are your roof's first line of defense. In Norcross, heavy rain can overwhelm old or clogged gutters, causing water to back up under the roof edge and into roof valleys or against the chimney—key leak points. Our gutter installation and replacement services ensure water is channeled well away from your roof's critical junctions. This proactive step is one of the most effective ways to mitigate common local leak issues.
