Leaky Garage Roof...Patched?

Okay, I got up on the roof yesterday morning and did my super awesome high end roof patch job....

After talking over options with several pros I came up with this half-assed repair idea. I would use this fancy roofing repair caulk to fill the holes where the shingles had cracked apart and use a piece of flashing metal to make a temporary metal cap shingle.

First off, gotta get up on the roof safely.

I love this ladder...I think some pros might think a ladder like this is 'gimmicky' but it's been super useful for us. We've used it as a straight ladder, a platform when we were grinding all those flooring nails down at Chez 2.0. Here it's being used as a nice roofing ladder (won't F up the gutter).

The Supplies

Yep, can't ya just tell that its going to be a 'high-quality' job? Before I went on the roof I used the clear packing tape on the underside to seal the holes that went all the way through.

And then I just filled all the cracks with the goop....it cleans up and tools with mineral spirits...I probably should have brought some up on the roof with me to tool the caulk but I didn't...I THINK I forced the caulk down and got it where it needed to go...we'll see....we got a one day reprieve from the rain so I'll have to wait until tomorrow...

Now for the super ghetto-fab metal cap shingle.

I ran a BIG bead of caulk around the area before laying the 'shingle' on it. Then I tried to nail through the caulk bead. Just in case I spooged a bit of caulk on to cover the nail heads.

Looks pretty sweet doesn't it?

Of course when I was all done and out of fancy goop I noticed this...

The cap shingles under where I had put my stuff are looking like they are about to go...dang...

Let's hope that it rains tomorrow and I get no leaks....
This roof is totally trashed and really, really needs to be replaced...let's just hope that we can band-aid it along for at least this rainy season....

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

Doesn't it look all spooky with the real spiderwebs?

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.
