Two Problems That May Develop With Asphalt Shingles in Gainesville, FL

by | Sep 25, 2019 | roofing

Asphalt Shingles in Gainesville FL can develop stains from a broad range of causes. Staining is usually dark in color, making it most noticeable on light-colored shingles. Roofing contractors can eliminate certain types of stains and prevent the problem from occurring again. Another problem that occurs with shingles is granules coming loose and washing off with rainfall. Homeowners find the granules in the gutters and at the bottom of downspout extenders.


Stains on asphalt shingles in Gainesville FL may be caused by plant growth, such as moss, algae, or lichens. Moss is easily removed manually, while lichens require some additional care. Many people don’t realize that the dark streaky stains they see on roofs are caused by algae growth. They worry that this is mildew, especially because the streaks tend to appear in shady areas. Roofing contractors eliminate those marks with a bleach solution and gentle power washing.

The algae growth can be prevented in the future by the installation of zinc strips near the top of the roof. Zinc ions are released from the rods when the metal gets wet, and those ions kill algae.

Granule Loss

It’s natural for shingles to lose some granules at first after a new roof installation. They also will gradually shed some over time. Those small particles are intended to provide extra protection from weather elements, so they are integral in asphalt shingle roofing.

If rain tends to pour down harder on one part of the roof, those protective granules will be shed sooner than on other areas of the structure. For example, a rain gutter on the second story that pours rain down on the first-story roof causes significantly more wear and tear on the shingles. Upper-story rain gutters should empty into another gutter or a downspout to the ground. If the gutter design can be modified, a roofer can replace shingles that have become very worn in this part of the roof.

Once most of the granules have washed away from most of the shingles, it’s time to consider roof replacement by a contractor such as Keeler Roofing. Get more information on this particular contractor at the website.
