Alliance Roofing Contractors | Roofing Services in Sellersville, PA 18960

While it may seem unrelated, clean windows are a critical part of home maintenance. In Sellersville, our weather can cause debris and mineral deposits to build up on windows, which can then wash onto your roof and into your gutters. This debris can accelerate wear on shingles and contribute to gutter clogs that lead to water backup and ice dams—common culprits of flashing failure. Our thorough window cleaning service removes this debris at the source, supporting the overall health of your roofing system.

Absolutely. Chimney flashing leaks are a frequent issue we address for Sellersville homeowners due to the expansion and contraction caused by our temperature swings. Our repair process involves carefully removing the compromised old flashing, inspecting the chimney structure and surrounding shingles for water damage, and installing new, code-compliant flashing custom-fitted to your chimney. We use durable metals and proper sealing techniques to create a watertight barrier that will withstand our local climate for years to come.

In our Sellersville climate, repeated freeze-thaw cycles and thermal expansion are the main causes of flashing separation. The metal and roofing materials expand and contract at different rates, eventually breaking the sealant bond. Our lasting repair goes beyond just re-caulking. We assess the root cause—often improper installation or inadequate fastening—then re-secure or replace the flashing as needed. We use high-grade, flexible sealants designed for our temperature range and ensure the new installation allows for necessary movement, preventing a quick recurrence of the problem.
