Roof Stains

If you’ve noticed stains on your roof, it may be nothing serious, but it’s important to inspect it right away. Roof moss, lichen, and similar plants can go through shingles and to the roof deck. When they get in contact with wood it starts to rot. Rotting wood is extremely hospitable surrounding for mold to grow, and once you have a mold taken over your roof, you have a serious health hazard.

Now, there are always aesthetical reasons to keep your roof clean. Cleaning a roof can elevate your home’s market value and it can also be very beneficial for the house itself. Dark spots on the roof accumulate more of the sunlight and they create a significant difference in temperature. There are some different types of health risks when it comes to different roof stains, so let’s go through some of them.

  • Roof Algae – Blue-green type of algae, commonly found in warm climates with humid summer seasons. Their spores get carried away, and they land on the roof where they feed on the limestone filler commonly used with asphalt shingles. As they feed and grow, they accumulate more water, making their surroundings extremely susceptible to the development of other organisms.
  • Fungi – Fungi developing on your roof are probably one of the biggest structural risks that can happen to your home. The tar that is commonly used in roofing projects acts as a nutrient for fungi. The fungi keep feeding on asphalt granules as they provide a perfect source of nutrients. These granules act as a UV protection and insulation, so once they are gone, rapid deterioration will occur.
  • Mold – Not all mold species are harmful to our health, but any excessive growth should represent a problem. There are certain types of mold that can be seriously dangerous for your health. Our organisms have quite strong defense mechanisms against almost all type of fungi, but fungal colonies help create high concentrations of mold, with very dangerous organic chemical metabolites.
