Cardinal Roofing and Exteriors | Roofing Services in Fort Smith, AR 72908

Fort Smith's heavy rains can overwhelm the valleys—the critical intersections where two roof slopes meet. Leaks here often stem from worn flashing, improper installation, or debris buildup. Our fix involves a detailed inspection to locate the exact failure point, clearing all debris, and either resealing or completely replacing the flashing with durable, waterproof materials to ensure a long-term seal against our local downpours.

The humid climate in Fort Smith creates the perfect environment for Gloeocapsa magma, a type of algae that feeds on moisture and limestone in asphalt shingles, leaving dark streaks. Yes, they can be safely cleaned! We use a low-pressure, specialized cleaning solution that kills the algae without damaging your shingles. We also offer preventative zinc or copper strip installations to inhibit future growth.

After major storms, check your attic for any water stains or moisture near roof valleys. From the ground, look for visible debris in valleys and any dark, streaky discoloration on your roof's north-facing slopes, as algae thrives with less sunlight. If you spot these signs, call us for a professional assessment. Early intervention on valley leaks or algae can prevent much more costly repairs down the line.
