Tack down the peak s tar paper.
Overlap on roofing paper.
In general overlaying a new roof takes less time less labor and thus less money.
Most roof felt pieces have guidelines stenciled into them to ensure you apply them in straight parallel lines.
It s best to wear gloves and protective eyewear for safety purposes.
Use a utility knife to trim all excess paper on the last pass.
The spacing between the nails on the drip edge should be less than 12 inches apart.
This creates a waterproof barrier similar to the scales of a fish.
Where the drip edge meets a valley or a hip cut the pieces with overlapping tabs.
Valley ridges and hips should have a 6 inch overlap of paper.
Section of paper on a steep roof or when it s windy.
Staple down the tar paper.
Position the next course of tar paper farther up the roof so that its lower edge overlaps the upper edge of the paper in the first course by 1 foot.
Paper can be fitted around vent pipes by cutting a slit and then putting it over the pipe.
Roofing felt is required to overlap 2 inches over the lower felt course.
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.
Practice on a couple of 10 ft.
The drip edge should extend at least 2 inches on the roof.
Allow about 4 inches 10 cm of overlap between the bottom of the second row and the top of the first layer.
Sections until you get the hang of it and don t roll out a 25 ft.
The overlapping felt creates a secondary barrier for moisture and wicks water away from the shingles above and the sheathing below.
If you re fastening the paper with a staple hammer try to get a staple in every square foot of the paper photo 5.
This has advantages and disadvantages and each of those should be weighed carefully.
However this can only be done once.
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.
If you rolled the first row from west to east the new row should be east to west.
Overlap seams on the same row 6 in.
Fold it down over the peak so that each side overlaps a piece of tar paper below the peak.
Remember to always overlap roof paper at valley ridges and hips by six inches.
Apply each row in a perfectly parallel manner.
Press the tabs firmly to make crisp corners with no gaps and attach with roofing nails.
When you overlay a new roof you attach the new shingles or other roofing material to the existing roofing material.
Cut a slit from the side of a paper roll to accommodate vent pipes.
Pay special attention to movements on top of any roof.
