Tips For Installing Replacement Roofing Felt


If one of your home improvement projects this spring is to install a new asphalt shingle roof on your home, then knowing how to work with roofing felt is very important. By taking care and correctly installing the felt layer for your roof, you can ensure that the roof will be waterproof and look professionally installed. To this end, here are some tips for installing replacement roofing felt for the first time:

Tip: Strip Everything Off of the Roof's Plywood Underlayment

As with a painting project, the success of your roofing felt installation hinges on you having properly prepared the roof's plywood underlayment for its installation. The more meticulously you prepare the underlayment, the easier it will be for you to install the new felt and shingles. 

When you strip off the old roof, you need to take the time to remove any wood splinters or nails that are sticking up from the plywood underlayment. Also, any underlayment that is damaged or has water staining on it needs to be replaced. 

Tip: Install Roofing Felt from the Edges of Your Roof Working Upward

In order for the seams of your roofing felt to be correctly orientated, you need to install the felt from the edges of your roof working upward. Each subsequent layer needs to be overlapped at least a few inches over the previous layer until you reach the peak of the roof. Once you reach the peak of the roof, cut the felt so that it meets together in a seam. Over the top of this seam, you need to install a strip of the felt so that it overlaps multi-inches on each side of the roof. This strip is vital to keep the roof waterproof.

Tip: Cut "X" Shaped Openings in the Roofing Felt to Install it Around Vents

Anywhere there is a vent sticking out from your home's roof, you need to install roofing felt around it. However, instead of cutting holes into the felt, you should cut "X" shaped areas in the felt. Lift the roofing felt over the vents and pull it down into place. Using this technique will prevent water from running down the vent and under the new roofing shingles. 

Finally, you will need to install flashing around any areas where you have a vent pipe. The flashing will further help to keep your new ashphalt shingle roof from leaking water when it rains.

repairing and preventing roof rot on your eaves

When the gutter system on your roof doesn't work as it should, your house could sustain serious water damage. The roof should never be exposed to more moisture than it needs to be, so the gutters are designed to carry the water away from the roof. One thing that homeowners sometimes forget is the protective drip sheeting that covers the edge of the roof just above the gutter. This will lead to expedited roof rot along the eaves.
