How to staple roof underlayment.

Cut drip edge flashing at an angle at the corner press it lightly against the eave end. I checked certainteed and all i saw was that they. Overlap each row at least 3 to 4 inches. Install new flashing metal.

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. The overhang to the next strip should be 3 8 inch. Overlap and cut drip edges.

Start the roof felt at one bottom corner of the roof. I looked at gaf website and their instructions say in bold do not use nails or staples without caps. If you live in an area with inclement weather you should consider using a special ice and water protector. The paper should then be nailed in or stapled every three to four inches across.

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. With staples or plain roofing nails the heads can sometimes tear right through the underlayment. All nails and staples should be placed on the lower half of the paper. 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.

I only recall one saying they used caps. Apply drip edge to the eave. Start by laying asphalt felt or other underlayment over the roof. They re certainly faster and easier to install.

Where a roll ends and a new one is begun the two rolls should be overlapped by four inches. A recent post on underlayments brought up another subject of underlayment attachment.
