These are all samples derived from a 10 year old roof.
While these shingles may only appear to be dirty, there is much more going on with your shingles.
We were able to take some excellent photos to give our clients a microscopic view.
This hopefully will assist you in understanding that removing them is crucial in the preservation of your roofing system.
Keep looking further down the page for an excellent close - up!!
