How To Staple Roof Underlayment

A recent post on underlayments brought up another subject of underlayment attachment.

How to staple roof underlayment.

Start the roof felt at one bottom corner of the roof. Overlap each row at least 3 to 4 inches. I checked certainteed and all i saw was that they. The overhang to the next strip should be 3 8 inch.

If you live in an area with inclement weather you should consider using a special ice and water protector. Using your staple gun secure the felt to 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. Cut drip edge flashing at an angle at the corner press it lightly against the eave end.

I am deciding on a contractor for a new roof and as i recall most said they simply staple the underlayment. I looked at gaf website and their instructions say in bold do not use nails or staples without caps. However depending on local roofing and fire codes it may be appropriate to secure synthetic underlayments with staples. Start by laying asphalt felt or other underlayment over the roof.

Where a roll ends and a new one is begun the two rolls should be overlapped by four inches. I only recall one saying they used caps. Overlap and cut drip edges. With staples or plain roofing nails the heads can sometimes tear right through the underlayment.

They re certainly faster and easier to install. Apply drip edge to the eave. Install new flashing metal. All nails and staples should be placed on the lower half of the paper.

Roof underlayment prevents the roof deck from being exposed to the elements before or while the roofing material is being installed. Apply and attach drip edge.
