Dear Mr. Scholtens:
I have visited the above referenced property and my observations are as follows:
1. The garage doors are 10' in width. The roof trusses rest on the door headers,
giving a uniform distribution load of:
10# DL and 30# LL = 40#/sf.
40#X 12'=480#/ft.
The headers presently used are 2-2 X 10's spanning 10'. Douglas Fir Use Book
indicates that the use of a 4 X 10 beam/1500 psi fiber stress will support 545#/ft.
(Uniform Loading) Therefore, use 1- 2 X 10 glued and nailed to the existing
headers.
2. There is also the issue of the header overhang not being sufficient by 2-1/2".
The solution to this is the addition of a 2 X 6 stud under the existing header
beam in the middle of the overhang as well as gluing and nailing 3" o/c a 7/16
OSB sheathing on the structure under the overhang.
