Common signs include interior water stains on ceilings or walls, damp spots in your attic, and granules from shingles accumulating in gutters. In Waltham, where underlayment is a frequent issue, it's also wise to check for curling or buckling shingles after heavy weather. If you notice any of these, it's time for a professional inspection to prevent further damage.

We start by safely cleaning existing algae stains with specialized, low-pressure solutions that won't harm your shingles. For long-term prevention, we often recommend and install algae-resistant shingles, which contain copper or zinc granules that inhibit future growth. This is a smart investment for Waltham homes, as our humid climate can encourage algae to return.

In many cases, localized underlayment damage can be repaired without a full roof replacement. Our approach is to carefully remove the affected shingles, replace the compromised underlayment section with new, high-quality material, and reinstall the shingles. We'll provide a honest assessment—if the damage is widespread or the roof is near the end of its life, we'll discuss all options with you.
