Cornerstone | Roofing Services in Meridian, ID 83642

In our climate, flashing—the metal strips sealing roof joints—can separate due to thermal expansion and contraction, improper installation, or wear from wind and hail. Cornerstone's experts inspect the flashing around chimneys, vents, and skylights, resealing or replacing it with durable materials to prevent water intrusion and protect your home's structure.

Roof valleys channel a lot of water runoff, making them a common leak source, especially with aging shingles or compromised underlayment. We repair valley leaks by carefully removing damaged materials, installing new waterproof underlayment, and ensuring proper shingle weaving or metal lining to create a seamless, high-capacity drainage channel for Meridian's rain and snow.

Absolutely. Proactive maintenance is key. We recommend annual inspections, particularly after severe weather, to catch minor flashing issues or valley wear early. Our preventative services include clearing debris from valleys, resealing penetrations, and reinforcing vulnerable areas, which can extend your roof's life and prevent costly emergency repairs for Meridian homeowners.
