Are their any testing methods that roofing manufacturer’s use to determine cause of wear or defects?
I inspected a house in September 05 that had a few areas of very damaged shingles (house is 1 year old). The contractor replaced shingles due to damages. Well, the roof is getting worse in the other areas and the manufacturer said they tested the material to find out that the roof was pressure washed (and it may have been pressure washed by the previous owner, why I don’t know)
Is this possible to determine if a roof was pressure washed besides just a visible inspection?
No blame on me… I am just trying to help a past client figure out how to handle it.
