Roofing Tar Paper Overlap

Even if there s older tar paper in place you should simply rip it off and replace it.

Roofing tar paper overlap.

Install all subsequent courses with the same overlap until the top edge of the paper is within 6 inches of the roof s peak. Make sure the rolls overlap by at least four inches and staple them into place on the wood. Step 6 overlap next roll. Roll the roof paper up and over the peak.

Therefore a 2 inch overlap provides redundancy at the edges where the barrier is weakest. Once the tar is applied tar paper can be carefully placed on top of the hot tar using a mop to sink the paper into the asphalt. Roofing felt is required to overlap 2 inches over the lower felt course. Step 5 secure ends.

This will help give you a moisture barrier on the roof. Some roofers prefer to attach felt underlayment with 1 inch roofing nails or special nails with plastic washers but most codes allow staples which are easier to drive. The roofing felt should be applied in layers that overlap. It is used for temporary roofing for weatherproofing and as an underlayment under shingles or other permanent roofing materials.

Experienced professionals never allow the hot tar to clump up or build up in any area. Tack it firmly in place. Climb onto the roof and lay a second strip of tar paper above the first strip overlapping it by about 5 inches. Roof felt also known as tar paper is a waterproof fiberglass product.

Once you get close to the top add another layer of felt so that you overlap the ridge of your roof by about 1 foot 0 30 m. Secure the outside edges with plastic capped roofing nails at 12 inch intervals. Step 4 over the peak. The overlapping felt creates a secondary barrier for moisture and wicks water away from the shingles above and the sheathing below.

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. Make at least three layers. As you work the paper can be tacked down in the center so it won t blow away. As long as the wood on your roof is in good condition you can go ahead and put tar paper down.

Staple down the tar paper. This overhang will ensure water will not enter underneath the paper getting trapped on top of the wood roof planks. Continue overlapping strips up each side of the roof.
