Roof valleys are high-risk areas where two roof slopes meet, channeling large amounts of water. In our climate, ice dams, debris buildup, or worn flashing are common culprits for leaks. We repair them by first identifying the exact source, then carefully replacing damaged flashing, sealing gaps, and ensuring the valley is properly reinforced to handle heavy water flow, preventing future issues.

Underlayment is the critical waterproof barrier beneath your shingles. If it's compromised by moisture, age, or improper installation, it can lead to rot in your roof deck and structural damage. The fix involves carefully removing the affected shingles, replacing the damaged underlayment section with a modern, high-grade material, and reinstalling the shingles to restore your roof's primary defense against Wisconsin weather.

Keep an eye out for interior signs like water stains on ceilings or walls, especially near the roof's peak or in upper corners. Outside, look for missing, cracked, or curling shingles in the valleys, or rust spots on the metal flashing. If you notice granules from shingles in your gutters or suspect an issue, we recommend a professional inspection to catch and address it before major damage occurs.
