How to staple roof underlayment.

Overlap each row at least 3 to 4 inches. Start by laying asphalt felt or other underlayment over the roof. With staples or plain roofing nails the heads can sometimes tear right through the underlayment. Using your staple gun secure the felt to the roof.

I looked at gaf website and their instructions say in bold do not use nails or staples without caps. Apply drip edge to the eave. They re certainly faster and easier to install. However depending on local roofing and fire codes it may be appropriate to secure synthetic underlayments with staples.

I checked certainteed and all i saw was that they. A recent post on underlayments brought up another subject of underlayment attachment. I am deciding on a contractor for a new roof and as i recall most said they simply staple the underlayment. Apply and attach drip edge.

Tack it in place at the corner with the end flush with the end of the roof and the bottom edge of the roll right along the bottom of the roof. Ideally the roof covering material would be installed as soon as possible but in reality the roof may be protected by only the underlayment for days weeks or sometimes months. If you live in an area with inclement weather you should consider using a special ice and water protector. The overhang to the next strip should be 3 8 inch.

Where a roll ends and a new one is begun the two rolls should be overlapped by four inches. Roof underlayment prevents the roof deck from being exposed to the elements before or while the roofing material is being installed. All nails and staples should be placed on the lower half of the paper. Overlap and cut drip edges.

I only recall one saying they used caps. Start the roof felt at one bottom corner of the roof.
