Roofing Contractor Sacramento Algae Growth  

Algae Growth
Algae growth causes a dark discoloration on the roofs. The algae is usually brown to black in color which results in a streaked, dirty looking roof. It can be mistaken for soot, dirt or tree droppings, which typically produce only localized discoloration. It’s caused by the growth of airborne algae which deposits on your roof. The algae does not affect the service life of your roof, however, moss feeds on algae. When moss grows on shingles it attaches to granules. When moss is removed from the roof, it takes granules that reflect UV rays with it, exposing waterproofing asphalt and shortening the roofs life.

Indoor Symptoms for Roof Replacement

Roofing Contractor Sacramento Indoor Symptoms  

There are a number of indoor signs to indicate that your roof may be in need of replacing including ceiling spots, sagging between rafters or an outside light that is visible through the roof. The most obvious of the signs, which are ceiling spots, are easily visible and would be a clear indication of leakage. If a roof is found to be leaking, and appropriate repairs or a reroof is not installed, the water damage may cause additional damage to your insulation and increase your energy costs.
