Synthetic underlayment is much more tear-resistant when exposed to high winds and foot traffic than asphalt felt underlayment. Since synthetics do not absorb moisture, they are resistant to fungal growth and are wrinkle-free. Synthetic underlayments are ultraviolet (UV) resistant for between six and twelve months.

Will tar paper keep rain out?

Tar paper, also known as Roofing Felt, is both a volatile moisture barricade, as well as the extra protective layer between the plywood and the shingles.

Is tar paper a good moisture barrier?

Fortunately a number of materials, including traditional asphalt felt (tar paper) have this ability to stop liquid water while remaining “permeable” to water vapor.

Is it OK to overlap house wrap?

Improper overlapping of roles of house wrap can cause air leakage. Overlap and seal vertical seams by at least 6 inches. Overlap and seal horizontal seams by at least 4 inches. Air leakage can occur if the house wrap does not reach the top of the wall.
