Is roofing felt paper necessary on a shed?


Roofing felt paper is necessary on a shed, as it not only protects the interior from water damage but also extends the life of the shingles, felt is asphalt-infused synthetic or wood composite paper that repels water. It provides a smooth, unbroken surface for the application of shingles.


How to install roofing felt paper?


Install roofing felt paper is not difficult. your biggest concern will be trying not to tear it when you install the shingles.

just as you would with shingles, your first layer of underlayment will be at the bottom.


Step 1: roll out the first layer of felt, starting on the left and rolling right. Make sure you nail one corner with plastic capped, galvanized felt nials,. Line up the left edge along the side of roof and nail the other corner.


Step 2: nail a maximum of every 8 inches along the edges. Your asphalt coated felt will self-seal the nail holes, so in theroy, your nail holes won't allow moisture to penetrate those areas.


Step 3: make sure your roofing felt paper goes over and above the drip edge on the lower edge of the roof. Do not nail too close to the top of the felt, as your net layer will overlapand you will nail through the overlap to fasten both rows at the same time.


Step 4: install the next layer of roofing felt paper, being sure to overlap up to 4inches over the previous layer. If you run out of felt and have to start a new roll on the same row, make surface your overlap by at least 6 inches.


Step 5:nail through the overlap to secure both piece of felt. Repeat until the roof is complete.
