Use Roofing Felt Insulation to Prevent Leaks

Roofing felt insulation is fitted under the roof of your house to stop water leaking through into the space below. This though is only one of the benefits of roofing felt insulation.

If your roof is made out of wood, asphalt or shingles, then it needs another protective layer under it to stop water leaking into the house. The material for this usually comes in the form of roll of cardboard or paper saturated with asphalt and impregnated with bituminous coal and tar to make it water proof. All you need to do is cut the roll to the right length for your roof. Roofing felt also comes in varying thicknesses and needs to be looked after properly if it is to stay intact over a long period.

The tell tale signs of a damaged roof are damp spots, pores, cracks, blisters and changes in color. The benefits of roofing felt insulation include stopping this damage occurring in the first place.

As we as discussing the benefits of roofing felt insulation, we need to look at how you actually fit it. Before you start, you need to clean any decking thoroughly, making sure it is free of any debris or moisture, and also check for any damaged areas which will need to be replaced or repaired. Take out the nails with a flat-headed shovel and make sure the sheathing is dry.

For the best water shedding capacity, roofing felt should be fixed from the bottom of the roof in horizontal layers with the bottom edge of the deck covering the first layer of the felt. The layout of the edges should be drawn out before you start laying the felt on the roof.

Let us now turn to the installation of the new felt on your roof. The first thing to do is to chalk a line 33 5/8 inches above the eave line which will give you an overhang of 3/8 inches for the first strip of roofing felt. Moving up the roof, the lines should be separated every 34 inches.

You can then enjoy the benefits of roofing felt insulation.
