Karcher & Son Roofing | Roofing Services in Watchung, NJ 07069

In Watchung, the most common cause is worn or improperly installed flashing in the roof valleys, where two roof planes meet. Heavy rain and snowmelt funnel through these valleys, and over time, the sealant can fail or the metal can corrode. Our fix involves a thorough inspection to locate the breach, removal of any compromised shingles, and the installation of new, code-compliant flashing sealed with high-grade waterproofing materials to ensure a lasting repair.

Signs of underlayment damage often appear inside your home as water stains on ceilings or walls, especially after a storm. From the outside, you might notice curled or buckling shingles. The underlayment is your roof's secondary water barrier; if it's compromised, water can seep directly onto your roof deck, leading to rot, mold, and structural damage. We address this by carefully removing the affected shingles, replacing the damaged underlayment with a modern synthetic barrier for superior protection, and reinstalling new shingles to match your existing roof.

It depends on the extent of the damage and the age of your roof. A localized leak in a valley on a relatively new roof is typically an excellent candidate for a targeted repair. However, if the leak is widespread, the underlayment is saturated, or the roof is nearing the end of its lifespan (typically 20+ years for asphalt shingles), a full replacement is often more cost-effective and reliable in the long run. We provide a honest, detailed assessment to help you make the best decision for your home and budget.
