most contractors will warranty workmanship for just one year. If the roof
didn't leak for the first 3 years I wouldn't think that the shingle
installation wasn't the problem anyhow. shingles are warranted between 20
&
40 years but read the small print on the package, if they find one nail on
the whole roof penetrated the shingle anywhere but in that one inch strip
of
tar embedded in the shingle , the warranty is void. in other words the
shingle warranty & 39 cents can get your happy meal supersized.
my guess on the leak is that:

A) you had ice dams last winter & water backed up under the shingles on an
over hang or cricket or valley,

B) previous high winds have pulled some shingles or flashing up or away
from
a surface

C) it was a driving rain that blew in from some direction

D) your gutters need cleaning

E) a tree branch has damaged your shingles


need I continue?

PLEASE DO CONTINUE
ITS A LONG SHOT.........BUT WHAT THE HELL!
