Brevard Roof Moss & Algae: Safe Prevention for Shingles and Metal
Living in Brevard means enjoying the beauty of a temperate rainforest. With over 60 inches of annual rainfall and heavy shade from towering trees, Transylvania County is a stunning place to call home. However, that constant moisture and lack of direct sunlight create the perfect breeding ground for roof moss and algae.
What starts as a few green fuzzy patches or black streaks can quickly turn into a major structural problem. Understanding how organic growth damages your roofing materials and how to safely prevent it is critical for homeowners in our region.
1. Why Moss is a Threat to Asphalt Shingles
While algae mostly causes cosmetic black streaks, moss is a physical threat to your roof. Moss does not have traditional roots. Instead, it anchors itself to the porous surface of asphalt shingles and acts like a massive sponge, soaking up and holding rainwater directly against your roof.
As the moss grows thicker, it begins to lift the leading edge of the shingles. Once those shingles are lifted, wind driven rain can easily blow underneath them and soak your wood decking. If ignored, a moss problem will inevitably lead to rotten plywood and the need for a costly roof leak repair.
2. Safe Cleaning: Put Down the Pressure Washer
When homeowners see a dirty roof, their first instinct is often to grab a pressure washer. Blasting an asphalt roof with high pressure water is one of the worst things you can do. The pressure strips away the protective granules that shield the asphalt from UV rays, effectively ruining the shingles and voiding the manufacturer warranty.
The only safe way to clean an asphalt roof is through a process called "soft washing." This involves applying a specialized, low pressure chemical treatment that kills the moss and algae at the spore level without damaging the roofing material.
3. Preventative Strategies for Shingle Roofs
The best way to handle moss and algae is to stop it before it takes hold. You can drastically reduce organic growth by trimming back overhanging tree branches to allow more direct sunlight to hit your roof. Sunlight is a natural enemy of moss.
If you are planning a roof replacement soon, make sure your contractor installs algae resistant shingles. These premium shingles are manufactured with copper lined granules that naturally inhibit the growth of black algae streaks and delay moss formation.
4. The Ultimate Prevention: Upgrading to Metal
If your home is nestled deep in the woods with heavy tree coverage, fighting moss on an asphalt roof can feel like a losing battle. For homes in deep shade, the smartest long term investment is often upgrading to metal roofing.
A standing seam metal roof has a smooth, slick surface that sheds water and debris instantly. Because metal does not absorb moisture, moss and algae have virtually nothing to anchor onto. This same principle applies to flat commercial roofing systems like TPO, which provide a smooth, water resistant barrier that naturally deters organic growth on large facilities.
5. Protecting Your Investment
Maintaining a healthy, moss free roof extends its lifespan and protects your home from water damage. If your roof is already severely compromised by lifted shingles and organic growth, it might be time for a fresh start.
