three tab shingles

[jodil]

Three tab (interlocking) shingles are very commonly used up here and I was wondering if someone could tell me why they dont adhere to eachother as do other asphalt shingles? Is it the interlocking design that is suppose to maintain a good seal? In ND where the regular wind speed is 40mph and the rain comes down sideways I am puzzles as to why this is a commonly used material and why they dont adhere to eachother.

Thanks

I thought that the interlocking shingle was made for high wind areas. They are stronger than a normal 3-tab shingle with an adhesive strip when it comes to the wind.

I don't know, I have never seen a three tab interlocking shingle.

The three tab interlock is not rated for " high wind areas". They need to be hand sealed and nailed according to the man. company. East coast it is called hurricane nailing and fastening. Don't know what you would call it in ND.

Hi,

I don't think Jodi is talking about the conventional 3-tab. When I lived in Colorado I used to see a lot of T-lok shingles which have tabs designed to be held down by other shingles.

I very rarely see them around here; when I do they're typically at least a quarter of a century old, however they were common as lice on a rat in Colorado where it's pretty windy. I'm betting that's what she's seeing.

I rarely see those type around here either (in PA). When I do, they also are on older homes.
