Overlap On Roofing Paper

Cut a slit from the side of a paper roll to accommodate vent pipes.

Overlap on roofing paper. Section of paper on a steep roof or when it s windy. Staple down the tar paper. Use a utility knife to trim all excess paper on the last pass. Remember to always overlap roof paper at valley ridges and hips by six inches.

In general overlaying a new roof takes less time less labor and thus less money. Allow about 4 inches 10 cm of overlap between the bottom of the second row and the top of the first layer. It s best to wear gloves and protective eyewear for safety purposes. Apply each row in a perfectly parallel manner.

Most roof felt pieces have guidelines stenciled into them to ensure you apply them in straight parallel lines. Paper can be fitted around vent pipes by cutting a slit and then putting it over the pipe. Overlap and cut drip edges where drip edge pieces meet overlap them by at least 2 inches. The vertical leg of the drip edge should be at least 1 5 inches wide and extend at least 0 25 inches below the sheathing.

If you rolled the first row from west to east the new row should be east to west. However this can only be done once. Press the tabs firmly to make crisp corners with no gaps and attach with roofing nails. Roofing felt is required to overlap 2 inches over the lower felt course.

Where the drip edge meets a valley or a hip cut the pieces with overlapping tabs. This has advantages and disadvantages and each of those should be weighed carefully. Practice on a couple of 10 ft. Tack down the peak s tar paper.

When you overlay a new roof you attach the new shingles or other roofing material to the existing roofing material. Before securing the end of a row take time to walk the row smoothing out any rough spots and matching up the snapped chalk lines. Valley ridges and hips should have a 6 inch overlap of paper. The overlapping felt creates a secondary barrier for moisture and wicks water away from the shingles above and the sheathing below.

Adjacent pieces of drip edge should overlap at least 2 inches 51 mm. The spacing between the nails on the drip edge should be less than 12 inches apart. If you re fastening the paper with a staple hammer try to get a staple in every square foot of the paper photo 5. Install all subsequent courses with the same overlap until the top edge of the paper is within 6 inches of the roof s peak.

Therefore a 2 inch overlap provides redundancy at the edges where the barrier is weakest. Overlap seams on the same row 6 in. Pay special attention to movements on top of any roof. The drip edge should extend at least 2 inches on the roof.

Fold it down over the peak so that each side overlaps a piece of tar paper below the peak.
