4180 sw 99th Roof Leak

We bought the house at 4180 in April, and moved in June after doing repairs.

The roof leak slowly drools water down the corner between the garage and the front of the house. The actual underside of the leak at the bottom is hidden by a triangular space enclosed by plywood. This is under a valley in the shallow hipped roof between the 1960 house and the 1963 garage. There is one layer of 10 to 20 year old shingles on the roof.

There is also some plastic in the attic above the dining room, and there is a very small amount of water damage (now dry) on the living room wall. There is no sign of a leak in the attic, and no moisture on the plastic, just dust that has been there a long time. This leak was probably repaired years ago, and the plastic left in place.

We also would like to properly install an attic fan, now improperly attached to a small roof vent.

Here are some pictures:

0392 Leak near ceiling - discolored wood, possibly replacing original decking. Water drools down the exposed house side, possibly getting under the siding.

0393 Farther down the wall, moist drywall. If we can put a non-ugly tarp on the roof to temporarily keep the moisture out, we can finish and paint the drywall

0342 View from outside. No water noticed on wall outside, but top of soffit was wet

0343 View of valley. The garage roof to the left, the house roof to the right. The house is pitched about 4 in 12, the garage about 3 in 12, the valley 2.5 in 12. A gutter cleaning helper put some soap on the moss to allegedly kill it a few weeks ago - didn't work.

0345 The gutter was loose, with an edge digging a hole through a shingle. We reattached it with the two gray hex-head screws. The hole was farther down than the leak, though.

0346 Garage roof fits under house roof. The deep inside corner (dry) is above where the water dribbles down the wall

0347

0348 We put some extra shingle fragments between house gutter and garage roof to keep the gutter from sagging again.

0350 Looking up through soffit to wet spot on garage plywood. This is NOT the roof decking, but a piece of plywood just below it

0351

0352 Here is the leak from the inside of the garage, where we are installing drywall

0353 Misc roof shots from garage, some through the hole into the triangular cavity between house roof and garage roof

0373 View from attic towards the corner. The roof and the soffits are too shallow to physically reach the corner. The rockwool is dark but may not be damp
