Hi all,

A year or so ago i have a limb go right through the roof of my shed. At the time I did a total hack job on the repair and, no surprise, its now leaking. I’d like to repair it now but have never done any roofing before.

I’m attaching pictures of the roof from inside the shed and one of the roof of the shed (sorry for the sun glare on that one). It appears to be very simple, maybe some 1x material with the shingles directly on top.

I’m thinking I cut the damaged portion out and screw in some pressure treated plywood or replacement 1 x material then the shingles on top of that.

Does that make sense? Anything i need to aware of? Can the shingles go directly on top of the plywood, or does something need to be in between? Any special shingles or does it not matter?

Any advice is appreciated.

Nathan

The best way is to do it right. If you are not experienced with “interweaving” a shingle repair, then here’s my recommendation for doing it right:

1. Carefully remove the ridge cap shingles.

2. Strip all shingles and substrate (tar paper) from the affected half. If you are insistant on both roof halves being an exact color match, then strip BOTH sides.

3. Make the wood roof repair. Looks like your rook is sheathed in 1×12s, so it shouldn’t be too difficult to cut away the bad and add in a repair patch.

4. Cover the repaired half in 15-pound tar paper stapled down.

5. Nail on new shingles of the same type and color.

6. Nail on new ridge caps.

You should be able to complete the job in a weekend given the apparent size of the shed.

Good luck.

Cheers!

For that small an area, you could use a heavy duty trowel to slide under shingle and lift nails until you got several shingles up, down, left and right of the damaged area.

An ideal tool for cutting out the damaged section is an oscillating tool. Even a Harbor Freight might do. However, a circular saw set to the depth of the ply will work fine. Use either to cut at the center of the 2x’s, so the piece of replacement ply and the existing both have support, just enough to cut a square and remove the damaged piece.

Drop in your new piece and secure it.

Get some tar paper or even Tyvek from a construction site and install it over the patch and any other exposed wood. It should slip under shingles yet on the roof.

Now all you have to do is install your rows of shingles, starting from the bottom and with the new ones sliding under old, existing ones. Secure each row as you go.

This is about the same as my recent installation of a roof mount blower for ma’s kitchen.

yep they got it covered. I use flat bar to loosen nails from shingles, so you can slide out bad ones and slide in new. I generally use piece of ice n water when making repairs but not necessary. Also I don’t think it’s necessary to mess with ridge cap, and green treated may be corrosive on your roofing nails.
