BYs Construction | General Contractors & Roofing in Williamsport, PA 17701

In our area, repeated freeze-thaw cycles can cause ice dams and allow melting snow to seep under shingles, damaging the roof underlayment—the critical waterproof barrier beneath. As a local roofing expert, we don't just fix the visible leak. We perform a thorough inspection to identify all compromised areas, replace damaged underlayment with high-quality materials, and ensure proper sealing and ventilation to prevent future issues specific to our climate.

While a handyman can tackle minor interior leaks, repairing or replacing roof underlayment is a specialist's job. It requires specific knowledge of roofing systems, local building codes, and safety protocols. As licensed general contractors and roofing specialists, BYs Construction has the expertise to correctly diagnose the full extent of underlayment damage from snow and ice, execute a proper repair that addresses the root cause, and warrant our work for your peace of mind.

A comprehensive repair for snowmelt damage goes beyond shingles. Our general contracting approach includes: 1) A full assessment of the roof deck and underlayment, 2) Replacing any rotted wood or compromised materials, 3) Installing new, ice-and-water shield underlayment in vulnerable areas (like valleys and eaves), 4) Ensuring proper attic insulation and ventilation to minimize future ice dams, and 5) High-quality shingle installation. We manage the entire project to ensure your roof is restored to withstand Williamsport's next winter.
