:> I have an older ashphalt shingle roof
:> There is a spot about 2 swuare yards where water is seeping through
:> the nail holes.
:> replacing the whole roof is not yet an option.
:> What are possible temporary fixes to stop the leakage ?
:Go up on roof. Slip putty knife under shingles to break the seal. Cover
:nail heads with roofing cement (caulk gun or can) Dab a little more
:sealant around where you had to separate the original seal. Of course,
:don't bend the shingles back sharply when you pry them up. Being an older
:roof be extra careful on it.
:Keep in mind if the roof is in very poor of a condition, just walking on
:the shingles can cause additional problems. Not saying it's gonna happen,
:just that it could.
Do it when conditions are dry, if possible, but also when it's not too
hot. Walking on a hot asphalt shingle roof will damage the shingles far
more than when it's cool!
