How Do You Install Roofing Paper

How do you install roofing paper.

Do not nail the drip edge to the fascia. Step 4 over the peak. If you install roll roofing using the double coverage method it will last longer. If you run out of a piece of tar paper halfway across a strip you re laying cut a new piece and overlap the old one by five inches continuing across the roof.

If your roof contains any vents or flashing place a small piece of tar paper above each one overlapping the top edge of the vent to prevent water from running down and into the roof. If you take the time to properly prepare the roof then laying the felt will be easy. It also helps if you first install a layer of roofing felt. Step 5 secure ends.

For extra durability you may install roll roofing in two layers. But as with so many other projects the key lies in the prep work. Do the same when you reach the peak from the other side of the roof. It should hang freely over the edge.

To install roll roofing you ll need to cut the material into long strips of the correct length for your roof and lay it flat. Because your roof deck might not lie perfectly straight or flat a layer of roof paper gives an even uniform surface upon which you can install your shingles. Roll the roof paper up and over the peak. Once you understand what it does and you know which one you need you are ready to lay the underlayment for your roof.

Applying roofing felt first will better protect the sheathing against condensation as well as against leaking. Felt paper also called tar paper or builder s paper helps shed water that gets under the shingles protects the asphalt shingles from the resins in the wood decking increases. Before you install the underlayment fasten the drip edge that covers the fascia on the eaves. When you install the paper on the roof forming the other side of the valley lay the ends so that they overlap the paper already there by about a foot and again cut the ends parallel to the valley.

The strips should always be horizontal. Whether you re building a new house or putting a new roof on your existing house installing tar paper first helps waterproof the roof and prevent leaks. Step 3 overhang paper. Allow for a inch overhang of paper down each side of the roof when unrolling the paper.

This overhang will ensure water will not enter underneath the paper getting trapped on top of the wood roof planks.
