Asphalt roofing is the staple of modern home construction. We service hundreds of homes every year with mossy asphalt shingles. Our method is the safest for your shingles and most recommended by roofing material manufacturers. Rooftop moss removal is a 3 step process:
- Physically remove the moss from your shingles.
- Apply treatment to kill microscopic, unseen moss material.
- Clean the gutters of fallen moss material (if not protected by gutter guards).
Power washing is almost always the most effective way to clean metal roof surfaces. Victoria Moss & Gutter services almost all forms of metal roofing with few exceptions such as metal shingle roofs. Normal metal roofing is quick and easy to clean and our treatment works very well at killing the types of moss, algae, and lichen that typically appear on metal roof surfaces.
Either concrete or clay tile is typically power washed. The porous surface of tile roofing make for excellent substrate for moss, lichen, and algae. Pressure washing cleans into these pores and does an terrific job of restoring your tiles back to their original look and color. Victoria Moss & Gutter cleans tile roofs on a case-by-case basis, so get in touch with us for a free quote to see if we can help your tile roof, and home, look beautiful again.
Victoria Moss & Gutter does not service cedar shake roof tops. In our professional experience, if your cedar shake roof is starting to sprout moss it may be time to replace your roof. Cedar is naturally resilient to moss growth. As your cedar roof ages it begins to lose that resilience. Moss growth is usually a sign that the shingles have begun to rot and may require replacing soon. We would typically not recommend getting us or any other company to de-moss your cedar roof as the potential for damage or future leaks is high.
Interlocking Asphalt Roof
Interlocking asphalt roofs are something we run into from time to time. They were most popular back when they were sold through Sears Home Services. These shingles did not last the test of time and were soon discontinued, and for good reason. These shingles are very brittle, posing a high risk for breakage, and can also be quite hazardous to walk on. For these reasons and more, Victoria Moss & Gutter does not service interlocking asphalt shingle roofs. If your interlocking asphalt roof is growing moss, it's time to replace it, even if you're well before your expected single lifetime. We would recommend that you the installer and have it replaced under warranty. We would not recommend having any company de-moss your interlocking shingle roof as the potential for damage or future leaks is high.
Concrete surfaces are best pressure washed to not just remove moss, but years of built-up dirt. Moss on concrete surfaces is usually growing into dirt and debris that accumulates over time. This acts as a nutrient rich substrate for moss growth to take hold and, with the right mix of shade and moisture, allows it to thrive. Power washing will blast away not just the moss, but also the dirt that your moss is living in. After the wash, Victoria Moss & Gutter applies our treatment to the surface of your driveway or patio to kill anything left behind too small for the naked eye to see. This ensures you don't have immediate grow-back of moss, lichen, or algae. Any remaining moss material dries up, dies off, and crumbles away within just a few weeks.
Asphalt surfaces are often much softer than concrete and can become damaged from pressure washing. Older concrete may also be a prime candidate for this cleaning method if the surface is starting to crumble away. Victoria Moss & Gutter first hand brushes the physical moss material from the surface with a metal brush. The metal brushes we use are gentle to the hard surface of your driveway, but very tough on the moss and lichen growing there. After most of the material is removed, we apply our very effective, environmentally friendly, and safe for pets and plants treatment to kill any remaining moss material that may still remain. This ensures no immediate grow-back of moss, lichen, or algae. Any remaining moss material dries up, dies off, and crumbles away within just a few weeks.
