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

How to staple roof underlayment.

I checked certainteed and all i saw was that they. Using your staple gun secure the felt to the roof. 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. I am deciding on a contractor for a new roof and as i recall most said they simply staple the underlayment.

Roof underlayment prevents the roof deck from being exposed to the elements before or while the roofing material is being installed. They re certainly faster and easier to install. 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. How to do it.

Cut drip edge flashing at an angle at the corner press it lightly against the eave end. However depending on local roofing and fire codes it may be appropriate to secure synthetic underlayments with staples. I looked at gaf website and their instructions say in bold do not use nails or staples without caps. The overhang to the next strip should be 3 8 inch.

With staples or plain roofing nails the heads can sometimes tear right through the underlayment. Start by laying asphalt felt or other underlayment over the roof. Apply drip edge to the eave. The paper should then be nailed in or stapled every three to four inches across.

Apply and attach drip edge. Overlap each row at least 3 to 4 inches. Install new flashing metal. Where a roll ends and a new one is begun the two rolls should be overlapped by four inches.

If you live in an area with inclement weather you should consider using a special ice and water protector. Start the roof felt at one bottom corner of the roof.
