how do i know if i need a new roof if i have no leak? i know my shingles are old, but i don't know if a replacement is necessary. i have black streaks on parts of the roof. what are the signs you need a new roof?
What kind of roof? Is it wood? How old is it? What about any flashing, what condition is it in?
The black streaks, are likely moss and that is a different problem, but can cause the roof to go bad.
Curling corners and visible loss of color granules exposing the black base layer on fiberglas/asphalt shingles. Splitting in wood shingles.
The black streaks can/should be cleaned off.
It's usually best to head these types of problems off at the pass...meaning, if you think it's time for a new roof, it probably is. Go reputable, my son. Tom
When you have to sweep bits of shingle off the driveway every few days, it's time.
