Vinyl Siding Installation
The lap joints of siding should always be staggered. Usually staggered at half the distance on top of the last piece installed below. The key idea is not to have a seem running vertically covering all pieces of siding.
A piece of siding is installed. Notice the end 1-1/2 inches does not have a nail strip. The trimmed end allows two pieces of siding to overlap one another.
Also note, the siding is fastened using roofing galvanized roofing nails. Each nail is left sticking out about a 1/4 inch. This allows for expansion and contraction.
