Kardynal Roofing & Siding | Roofing Services in Stamford, CT 06906

The underlayment is a critical waterproof barrier beneath your shingles. In Stamford, with our heavy rain, snow, and ice, damaged underlayment is a primary cause of leaks. It prevents water that gets past the shingles from soaking into your roof deck. When it fails, especially in vulnerable areas like roof valleys, it can lead to interior water damage, mold, and rot. Our inspections specifically check underlayment condition to catch problems early.

Roof valleys, where two roof planes meet, channel a lot of water. In Stamford, leaks here are often due to worn valley flashing, improper installation, or underlying underlayment failure from ice dams or debris. Our fix starts with a precise diagnosis. We then repair or replace the damaged underlayment and install new, correctly sized metal valley flashing using industry-best practices to ensure a seamless, water-shedding channel that handles our local weather.

Often, yes. If the shingles are still in good condition but the underlayment is compromised in specific areas (like around a leaky valley), we can perform a targeted repair. We carefully remove the affected shingles, replace the damaged underlayment section with a high-grade synthetic barrier, and reinstall the original shingles. This cost-effective solution addresses the root cause of the leak while preserving your existing roof where it's still sound.
