replacing ashphalt with cedar shingles - small roof


I am in the process of replacing a small roof ...sort of a lip over first floor..about 2 1/2 deep with cedar shingles...my contractor says he has done it before but i have doubts....i researched online ...got some good idea but am still confused.

most likely the current sheathing is plywood...does he need to put felt underneath...if yes , does felt need to cover entire area or does he need to leave some gaps for ventilation..this got me confused. also, i learnt that the first row should be double..is that true?

thanks

christy

If that site is confusing, you may want to purchase a book on roofing. The more pictures the better. I just installed about 120 square feet of cedar siding, this is a material that is a bit tricky to work with, since it can break easily, it can curl, and it is not dimensionally identical from piece to piece. Best to get a book that discusses all the ins and outs before you start work. If you are just trying to get up to speed so you can discuss the project with your contractor, a book would be good for that too.

This is for shingles and not shakes.

we are using shingles not shakes actually.. would it cause any problem if we completely cover the surface with felt?

No, not significantly if I understand the structure they are being applied to correctly from your description.

Is this an approximate 2 foot 6 inch ribbon decorative roof extending behond the exterior wall of the home?

If so, then ventilation will not be a concern.

But, the flashing detail where the sheet metal roof to wall angled apron metal goes would be.

Ed...you are correct...it is the decorative roof and you described it with 100% accuracy.

There is metal flashing already there...are you asking iif this flashing is present or not?

thanks

i found the answer in the video that is posted on cedarbereau site. they suggest that felt should be put under non-exposed part of the shingle only. As Ed pointed out, this roof is decorative ..so we may not have to follow these guidelines

The Cedar Bureau site is a good one and I think you have the answers you need.

The only thing I commented about as far as the roof to wall metal apron flashing goes, was to ensure that there was one in place and that it is re-usable or will be attended to if it needs to be replaced.

It is not critical as far as interior leakage goes, but you wouldn't want the overhang to get corrupted with moisture infiltration from an ongoing, albeit, slow and continual wall leak.

Good Luck,

Ed
