Seems I've seen this in my past....

2 layers of wood shingles. (NOT shakes!) A wood shingle layover....is it possible?

I looked at a roof to redo one time that had two layers of wood shingles, covered by a layer of plywood and then a layer of 3-1's and then a layer of T lox. Wow! we didn't do it!

---Just did a heavy CCA shake roof. You can order any type of shake you want. ---I have torn off 2 layers of wood shingles but never done a recover with cedar over cedar. ---I have also seen some shake over shingle. ---1x4 is correct for the eaves & gutter. The gutter 1x4 keeps the old roof from dropping pieces into the gutter. On the eaves it is very important as a secure nailing board for the recover roof. Otherwise wind might peel back the new roof at the eave. Wood shingles over skip do not make a very secure nailing surface. Although the overhang is usually solid deck I still like that solid 1x4 to nail into. ---I worked in the woods cutting shake bolts one year. I cut logs over 7 feet thick and windfalls that had been down for over 800 years. I saved up enough blocks to handsplit enough shakes to roof my garage. I split them 1 1/4" at the butt and tapered them by flipping the block after each piece. I nailed them on with 16d galv. nails. ---We've also installed 24" shingles but not often. Install like shakes but look like shingles. ---We've also installed 16" "shorty shakes." They run at 7 1/2" exposure. Last time I did one the bundles cost $2.00 apiece with 7 bundles/square. That is $14/square. At the time shakes were about $50/sq. You saved money on the shakes and lost money on the labor. We charged 2x for "shorties." Lanny

Twil, the 1 x 4 wants to be the same thickness as the total thickness of the old roof. A 2 x 4 would be too thick. It does work however. Shakes are the thick hand splits, while "shingles" are resawn and are smooth on both sides. Shakes used to be heavies 3/4 to 5/4" thick and then mediums 1/2 to 3/4" Now they are all mediums, but they charge more for them. I haven't put on a shake roof or a wood shingle roof for years. did some wood shinlge siding 5 year ago.

Funny rd :laugh:

We have a Steam Show 'round here in Sept or so where they have a sawmill set up and they make the shingles. They are not tapered however. But they are duplicating 1800's stuff, so maybe they were common. Actually the wood seems to be oak also.

I am not sure if these were used for roofs or what. They made them, and I have one. And that's about it.....

Illinois is the same way. I've never been anywhere else so I don't know any better! I called them all shakes up until Tuesday, July 12, 2011 @ 5:16 AM, or shortly thereafter

On another note has anybody ever made their own wood shingles/shakes? I bought a shingle froe over the winter and I might actually use it this winter for a pavilion I'm going to build around my wood burner.

Went to the source "Red Cedar Shingle and Shake Bureau"

He said to do what O/S said to do. But he kept insisting on a 2x4 while I was thinking 1x4.....

Indiana is very weird about this. Everyone refers to wood shingles as shakes, yet.........if you see one shake roof in every town or city you are really looking very hard. OTOH, I can note several wood shingle roofs, plus the old re-sheeters. I will have to bring in my "Red Cedar Shingle and Shake Bureau" guidebook to show them the pictures at the suppliers......

That was very common back east. I tore off many like that. never did one though. They would put "horse feathers" on each coarse to level out the roof.

We have done that before. You just cut the edge back and install a 1 x 4 around the perimeter, then nail another layer over it. It works just fine. a bitch to tear off though!

I don't know but I think a bonfire is order! Last time I went to a call to tear off two layers of cedar shakes, they were counting the starter course as a layer bahaha
