Do the other side of the roof the same way also with an overlap at the peak.
Roofing felt paper overlap.
Start at the bottom of the roofline and work up so any water that gets through the roofing material will shed down the tar paper and will not go under it.
The overlapping felt creates a secondary barrier for moisture and wicks water away from the shingles above and the sheathing below.
As you work the paper can be tacked down in the center so it won t blow away.
Roofing felt or tar paper is infused with a petroleum based solution to provide an additional layer of roof protection under shingles.
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.
Install the roofing felt on all roof sides extending it over the ridge of the roof and overlapping 8 inches there just as you did on the sides.
The roofing felt should be applied in layers that overlap.
Therefore a 2 inch overlap provides redundancy at the edges where the barrier is weakest.
Work up the roof to the peak and fold felt over the top overlapping at least 3 inches and fasten it on both sides.
Remember to always overlap roof paper at valley ridges and hips by six inches.
Adjacent pieces of drip edge should overlap at least 2 inches 51 mm.
The drip edge should extend at least 2 inches on the roof.
Roofing felt is required to overlap 2 inches over the lower felt course.
For a flat roof the same applies start at the lower end first working to the higher end and this should resemble tiles on a roof.
Installing roofing paper or felt is an essential element to construct a waterproof roofing system.
Atlas roofing provides a complete selection of roofing felt underlayment.
The last layer should go over both sides of the roof overlapping both side covered in felt.
30 saturated felt underlayment is specified for use as an underlayment between the roof deck and the shingles.
It also acts as a layer of insulation and water protection underneath roof shingles.
The roof felts are asphalt saturated and are manufactured with a high grade organic mat.
Hence this is why tiles are fitted on top of each other rather than sideways.
