Those common black stains are often a type of algae that thrives in our humid climate. While they can look concerning, professional cleaning is usually the first step. We use specialized, low-pressure cleaning solutions to safely remove the stains without damaging your shingles. It's important to address this promptly, as the algae can trap moisture and accelerate granule loss, shortening your roof's lifespan.

Signs of roof deck rot in Atco homes often include sagging roof lines, soft spots you can feel from the attic, or interior water stains on ceilings. This is a serious issue typically caused by long-term leaks or poor attic ventilation. If we find rot during an inspection, the affected decking sections must be replaced to restore structural integrity before new underlayment and shingles are installed. Ignoring it can lead to major structural damage.

The decision depends on the extent of the damage, the age of your roof, and the cause. For isolated issues like a few damaged shingles or a small area of deck rot, a targeted repair is often sufficient. However, if your roof is nearing the end of its lifespan (typically 20-25 years for asphalt shingles) or if the damage from algae or rot is widespread, a full replacement is usually the more cost-effective and reliable long-term solution for your home.
