How to tar paper a shed roof.

Tack one end of the felt in place so that it remains in place as you roll it out. It is placed between the roof decking or sheeting and the roof shingles. The ease of installation and affordability of felt makes it a must have for your next shed roof installation. Asphalt of course is one of the final products that comes out of a catalytic convertor that s used to refine crude oil.

It s purpose is to prevent water from penetrating the roof decking material like plywood or osb oriented strand board used for sheeting roofs. Felt paper is sometimes referred to as roof underlayment or tar paper. Start by measuring the length and width of one side of the roof in inches. This extra length will be folded over and nailed to the battens so that any water will drip off the edge without getting the wood wet.

Afterward multiply them to calculate the area. Roll out the tar paper along the bottom edge of the roof. The roofing felt should be applied in layers that overlap. For example if its length is 120 inches 10 ft and its width is 240 inches 20 ft the area is 28 800 square inches 200 sq ft.

Tar paper used to be made by soaking a porous paper made from cotton rag scraps with thinned liquid asphalt. As you work the paper can be tacked down in the center so it won t blow away. The most common weights are 15 pound and 30 pound tar paper. When investing in a shed a roll of tar paper is a small cost that can prevent costly damage.

Calculate the area of your roof by combining the area of each surface. Begin your first row of tar paper with the bottom of the tar paper slightly hanging over the edge of the roof. Cut lengths of shed roof felt to match the long side of the roof be sure to add 2 to 3 inches to the length at each end. 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 paper comes in different weights.
