Major Bentley Roofing | Roofing Services in Lenoir, NC 28645

Those black streaks or greenish stains are very common in our humid Lenoir climate and are caused by a type of algae called Gloeocapsa magma. It feeds on the limestone filler in asphalt shingles. While not immediately damaging to the roof's structure, it can retain moisture and degrade the shingles over time. We offer professional roof cleaning and can apply preventative treatments to inhibit future growth.

Finding granules in your gutters is a sign of normal wear, but excessive loss can be a concern, especially after the hailstorms we sometimes get in Caldwell County. Granules protect shingles from UV rays. Significant loss exposes the asphalt to faster deterioration. We recommend a professional inspection to assess the extent of the granule loss and determine if repairs or a replacement are needed to prevent leaks and further damage.

For long-term protection against our local issues, we recommend architectural shingles with algae-resistant copper or zinc granules. These shingles are thicker, offer better impact resistance for hail, and are specifically designed to inhibit the algae growth common in our area. During a consultation, we can show you options that provide superior durability and curb appeal for the Lenoir climate.
