Roof
Repair Upper Marlboro Maryland:
Sometimes roof repairs are a result of a
questionable design that needs
better-than-usual roofing techniques.
This job was one of those situations.
The roofing shingle is the top of the line
Certainteed Grand Manor -- a lifetime
warranted model. |
A tremedous
amount of water comes rushing down this roof
valley, so the roofing work has to be perfect
to contain the water. |
The roof is
at least a 12/12 pitch; maybe steeper. |
|
This nail
"blow through" just past the center of the
California cut valley was one of the leak
points. |
|
The mud
streaks are evidence that the water was making
it past the shingles in the valley. We
will use some ice and water shield and a
slightly different technique to try and solve
the problem. |
|
The sheer
volume of water finally broke through the 15#
tarpaper, which was no match for this unusual
situation. |
Ice and
water shield was installed in place of the
leaking underlayment, and Geocel Tripolymer
Sealant was applied to help the metal
flashings contain the unusual flood of
water. |
Flat head
"roofing style" screws were used instead of
regular roofing nails to maintain constant
pressure on the shingles. |
|
|
The entire
valley was then sealed with Geocel Tripolymer
and should hold up to the extreme water
flow. |
So far,
so good, as of this writing it's been
almost a year with no leaks . . .
|
Another
success, and on to the next roof repair
project. |
