T & T Roofing Siding & Remodeling | Roofing Services in Greensburg, PA 15601

We repair or replace separated flashing by carefully removing the compromised material, preparing the underlying surface, and installing new, high-quality flashing sealed with durable, weather-resistant compounds. It's common here due to our temperature swings and freeze-thaw cycles, which cause materials to expand and contract, eventually breaking seals. Proper installation is key to preventing leaks around chimneys, vents, and skylights.

The safest approach is professional remediation. We gently remove existing moss without damaging your shingles, then apply an EPA-registered treatment to kill spores. Crucially, we identify and address the cause—often shaded, north-facing slopes or overhanging trees common in Greensburg's neighborhoods. We can also install zinc or copper strips at the roof ridge for long-term, chemical-free prevention.

Absolutely. Both issues can lead to significant secondary damage common in older Greensburg homes. Compromised flashing allows water into your attic and walls, leading to mold, rotted wood, and damaged insulation. Moss holds moisture against the roof decking, accelerating rot, and its roots can lift and curl shingles, creating entry points for water. Addressing these problems quickly prevents much costlier interior repairs.
