I am inspecting a ranch style house with a gabled roof today. Originally it was built with a asphalt shingled roof and recently redone with concrete tile. I have not been in the attic yet but I am guessing I will see the standard engineered wood trusses that are so common to Phoenix.
Any advice? Are there certain things that would normally be done to re-enforce the structure?
here you can not reroof with tile unless you have an engineers report…they will not even take your app. until you have this report. I would check with your local building dept. but then again going this deep on the roof would be way over the sop…
I would recommend evaluation by a structural engineer if the client cannot produce documentation showing that the change to a heavier roof-covering material was approved by a structural engineer (for the reason Jeff mentioned).
I’ve seen pictures of rafters that broke under the weight of a tile roof. One house was so bad that the building department was notified by a HI and they basically condemned the house. Asphalt is about 2# per square foot and tile is 8-19# per square foot.
