When plywood is used on your roof, it has two main purposes. First is to support the weight of the shingles on your roof, as well as the weight of anyone who needs to be on the roof; and the second purpose is to anchor the shingle nails. So when choosing roofing plywood, the thicker the better, because it supports more weight, as well as adding another layer of protection for your home. Here at UBS we have a wide selection of roofing plywood, and we're sure we can find the right kind for your budget. Give any of our friendly sales personnel a call and we can fix you right up with a roof that your home can be proud of.
