I want to have my roof inspected.
It is Not leaking for 6 years now and was replaced about 10 years ago.
I Do lose 2 or 3 (tar) tiles annually when wind kicks up though.
Also, there are a few 12-18 inch areas where previous owner has masked
old damage with acoustic.
It's possible that was before last roofing was done.

Is it foolish to wait until leaks happen?

Anyone know what I should be looking for regarding credentials etc..?

Should I look for someone who does roofs exclusively when getting estimates?
I'm assuming estimates are free???
