Have heard of critters eating on the roof,
in fact, isn't this one of the reasons they say to NOT wash roof with anything citric, cause it will attract Mother Nature's critters?? Correct me MOCer's if I remember that wrong.
Gotta watch those low hanging branches. Right now the trees are sooooooo bad on the road we have to take out of here it takes us 10 minutes to traverse the 1.5 miles to the paved road. I have called the county to request tree cutting, the gal gasped when I informed her I did not want to pay for a new roof, as expensive as they are.
Small holes, etc. can be patched, one of the fellas will happen along to explain that process.
Good luck, let us hear what you do for a fix.
