R L Geist Roofing | Roofing Services in Santa Rosa, CA 95403

In Santa Rosa, roof valley leaks are often caused by our heavy winter rains overwhelming worn flashing, cracked underlayment, or debris-clogged valleys. We fix them by first performing a precise leak trace to find the exact entry point. The repair typically involves clearing the valley, replacing damaged flashing with corrosion-resistant materials, and installing new, high-quality valley underlayment to ensure water is properly channeled away from your roof.

Signs of moisture-damaged insulation in your Santa Rosa home include higher energy bills, uneven room temperatures, a musty smell in the attic, or visible damp spots or mold on the underside of the roof deck. We perform a thorough attic inspection to assess insulation compression, moisture levels, and ventilation. If damage is found, we safely remove the wet insulation, address the root cause of the moisture intrusion, and re-insulate to restore your home's efficiency and comfort.

Proper attic ventilation is crucial here because it prevents the trapped heat and moisture common in our climate from damaging your roof system. Without it, summer heat can bake shingles from below, and winter moisture from the home can condense in the attic, leading to wet insulation, mold, and wood rot. We evaluate and install balanced intake and exhaust systems, like ridge and soffit vents, to create continuous airflow, protecting your insulation and extending your roof's lifespan.
