What's on My Roof Suffolk County?

November 15, 2018

 

 

Most roof stains are caused by the growth of algae, lichen or moss that feeds on the organic material found in the materials that make up roofing shingles, mainly limestone that makes up the shingle matting.

This organic matter is the the food supply for the roof staining on the shingles.

These organisms are literally eating away at your roof surface.

The parts of a roof that receive the least amount of daylight will grow more moss of alga, lichen  or moss .

This explains why some homes could have roof stains solely on one side of the roof and not the other, typically the northern and/or western exposure or in heavily shaded areas.

 


 ALGAE on my Roof

Algae is a living organism that thrives on a wet roof, and the organic materials that make up the roof shingles.

Dampness triggers the growth.

Algae grows on and behind the tiny granules that cover the shingles.

This leads to ugly stains and streaks on the roof.

Roofs with alga stains absorb heat instead of mirror it, resulting in a hotter attic and cause higher home cooling costs as well as reducing the natural life span of the shingles.
Why is there MOSS on your Roof

Thick growth with its shallow roots keeps the roofing materials damp for extended periods of your time.

This wetness promotes the growth and causes ganuals to lift up.

Moss generally starts to grow at the highest of the vertical slots between the shingles.

These areas of asphalt shingles are the last place water evaporates from your roof.

Moss, like lichen colonies, can damage cause to shingles.


LICHEN  on your Roof
Lichens is a form of fungus, that grow with algae, resulting in a composite organism that characteristically forms a crust-like or branching growth on shingle granules.

Lichens place out root-like tentacles that penetrate deep into the shingle’s organic, oil base for nourishment, eventually wrecking them by making dark spots, or pock marks wherever they grow on the shingle.
