Common signs include sagging roof lines, dark stains on interior ceilings, a spongy feeling when walking on the roof, and musty odors in the attic. It's a frequent issue in Yuba City due to our climate—winter rain and summer heat can trap moisture in attics, especially if ventilation or insulation is inadequate. This persistent moisture slowly deteriorates the wooden roof decking from underneath the shingles.

We start with a comprehensive inspection to locate the source of the moisture intrusion, often a leak or condensation issue. After repairing the leak, we safely remove the wet, compacted insulation, which has lost its R-value and can promote mold. We then ensure proper attic ventilation is in place before installing new, high-performance insulation. This process not only restores energy efficiency but also eliminates the damp environment that causes rot.

It depends on the extent of the damage. We perform a detailed assessment to see how much of the roof decking (the plywood or OSB under the shingles) is affected. For localized rot, we can often perform a section repair by removing the damaged decking and shingles, replacing the structure, and seamlessly integrating new materials. If the damage is widespread, a full replacement may be the most cost-effective and secure long-term solution. We'll always give you a clear, honest recommendation.
