I never see shake roofs


Recommended Posts

The felt strips should be 18". The bottom edge of the felt should be above the bottom of the shake at twice the exposure. For example, with 24" shakes, felts extend up 14" onto the sheathing. Done correctly, I usually have to use a flashlight to look up under the courses to even see the felts.

The spacing between shakes should be between 3/8" and 5/8". Forget the Caravan, my full size Dodge conversion could pass through.

The side lap appears to be less than 1 1/2" between joints in adjacent courses.

I agree with Bill, way too much exposure of the felt and not enough offset. This guy needs to go back to school. Around here, that roof would begin leaking at about the 8 to 10 year mark after the felt had completely rotted away. Can't speak to Nebraska. I don't know what your sun/rain conditions are there. Go to the Shake and Shingle Bureau's site and get the correct skinny. You'll find them at http://www.cedarbureau.org.

The roof appears to have been installed while the material was wet with incorrect spacing and inferior, sub standard material.

The grade goes like this

Grade 1 Handsplit Resawn 24' x 3/4" Heavy Cedar Shakes.

Premium Handsplit Resawn 24" x 3/4" Heavy Cedar Shakes. (Add 15% to the first choice)

So..........the butt of the shake is a first give away ..1/2"

Here the correct installation method,

Is this acceptable? - NO

The tar paper is going to fade and wear out, no? - YES

I'd be looking for loose or missing and rotted shingles.
