Roofing/new roof, decking, truss load concern


we have a manufactured home, built in jan, 1 2002., it is 1813 sq. ft., double wide of course, we're getting a new roof put on soon, , the way these  homes arte constr. , ok., we have 1x2 trusses,spaced at 2 ft. apart, they better be no more than that, anyway, I need to know , 1 inch thick pine sheeting, is too heavy for this kind of construction?, can we go with 3 quarter inch pine decking, and still be safe?, plus  there putting in a ridge vent, that's needed, , and 1 layer of 3 tab asphalt shingles, we get several ft. of snow here , most winters and , sometimes ice., we do need to get a sturdier decking, to prevent any sags, please help, I want the best, and safest course to go here, thank you , very much for your time, ruth dickey.

I'd need more info or pictures. 3/4" board should be sufficient. You're only looking to hold people and snow on the roof and not refrigerators. I don't know what a double wide home means. If you get a lot of snow be sure the roof has enough slope for shingles. Low slopes will leak with shingles.

All aspects of residential Roofing. This includes shingles and flat (low slope) roofs. I have knowledge in the installation as well as the design of roofs from an engineering standpoint.


I have been doing roofing for 40 years. This was my father's business and I took it over in 1980.

I have written responses to artcles that I felt needed a response to and those responses have been published in roofing trade magazines.
