To stop the damage
Roof organisms are damaging your roof, these organisms, specifically lichens, algae and moss are busy feeding off of the organic material in your shingles. Basically, your shingles are their food source. And the longer you allow them to stay, the more damage they are going to cause.
Wood rot
Your roof lichens, algae and/or moss can eat right through your shingles and into the deck, this causes wood rot. And when your wood rots, moisture will start to get in through the cracks and create an environment hospitable to mold growth. Having mold growth in your home could pose many health risks to people and pets. You shouldn’t ignore roof stains. By having your roof properly cleaned, costly roof repairs can be avoided before there is any permanent roof damage.
Homeowners policy
Your insurance company is allowed to cancel your homeowners policy if you have a filthy roof. Insurance companies are becoming more and more demanding that homeowners have their stained roofs cleaned. And often, they will only give you a short notice to get it done. There have been many cases where the homeowner has been given less than a week to comply or they lose their insurance coverage. This is why it is extremely important to be proactive and to have your roof stains removed by professionals before the notice from the insurance company arrives. Your insurance company knows that an untreated rof stain problem will negatively impact the overall integrity of the roof, and that it can also lead to mold growth inside your home. Having a roof stain is seen as a risk that could cost your insurance company money in a claim.
Reflecting sunlight
If your roof is covered in moss, algae etc, it will no longer be able to efficiently reflect sunlight. The algae covered shingles will absorb the heat and thereby over-heat your attic and increase your cooling costs. A proper roof clean will gently, safely and completely remove the stains and restore your roof back to it’s former health and efficiency.
