What causes the black roof stains in Williamstown? There is a form of bacteria called Gloeocaspa Magma that is feeding off of the limestone in the asphalt shingle. This Algae usually grows on the north side only but can cover both sides of the roof if you are in a heavily covered area of trees. It will form as streaks being wider at the gutter line then tailing towards the ridge line. Eventually if left untreated it will overtake your entire roof causing rapid granule loss leading to early roof replacement. Think of roof cleaning as maintenance just like changing your oil in your car. We do this to keep our cars running longer. At the same time we are cleaning the roof to keep the roof clean and to allow it to achieve its full life potential which is anywhere between 25-30 years for a dimensional shingle.
Roof Moss Williamstown
Roof moss is another culprit that will cause the roof to break down prematurely. Moss is usually caused by oak trees that are overhanging your roof. Every spring these trees drop their spore and cause the start of the moss on your roof. the moss in time will eventually grow under the edge of the tab causing it to lift. This can potentially cause the tab to be lifted off during a high wind storm and then cause a leak into your attic.
We treat the moss will our specialized cleaning solution. Our solution will kill the moss from the top down to the roots. By doing this it will allow for the moss to decompose and fall off naturally without any damage to the shingle. It will take anywhere between 2-4 months but this is the better option compared to power washing which will destroy your roof.
