Leaky Garage Roof...gotta fix it ASAP
Got a day to fix a roof!!!
It's supposed to rain tomorrow.
Having never ever in my life ever really thought about roofing, I've not got a day and a half to stop our garage roof from leaking.
First, I had to determine where exactly it was leaking from. From inside the garage I closed the doors and went looking for sunlight showing through the underside of the roof....well, I found it. There appear to be three main spots where the roof is leaking, though having been up there and seen the condition of the roof I'm surprised it's not leaking in many more places. I stuck yellow pipe cleaners up through the holes so I could see them from above.
One of the main leaks and most light showing is this disintegrated cap shingle.
I don't think that there is a lot of water coming in through here but it has the most light.
From underneath
I found two other leaks, interestingly enough, where the roof sheathing has a joint.
I believe these leaks are where most of the water is coming in. It gets through the shingles and runs down the underside of the roof where it drips off in various places. See that horizontal crack in all those shingles? That coincides with the roof sheathing joint...coincidence? Those shingles are cracked totally in half and you can see right through into the garage...
Underside view
This, I believe, is the main leaking spot. Look at that fungus damaged sheathing...it's pretty spongy...as in, I don't think it'll take a nail...
Other Side
This leak looks more recent and the sheathing is still pretty solid.
The Plan:
I don't have one. Help...I need to stop this roof from leaking and have the patch hold through this wet season and probably one other...
I've been looking at the roofing isle in Home Despot and hey, you can buy shingles in singles! But you can not buy cap shingles that way...?
I guess my plan is to attach some solid plywood to the underside of the rotted out stuff and then use REALLY long nails to attach the shingles to the roof? How do I do that correctly?
The cap shingle...how do I plug that hole if I can't get a cap shingle to replace the rotted out one?
Any useful advice would be greatly appreciated.
