Other great roof felt tips and advice; Various roofing material can include shingles or tiles. Shingles are manufactured of various substrates, the most common being asphalt. When mounting the tar papers, ensure it’s the proper weight to support the roof’s sheathing and roofing materials. For asphalt shingles, customarily 20 weight roofing is used.
Before mounting the sheathing, ensure that it is dry. Wet sheathing will yield only problems later on which could result in your having to re-install all roof components. In severe climates dry sheathing is a good guarantee the roof will remain watertight.
Ensure when you install the tar papers, the strips are laying flat. Uneven felt surfaces could allow dust, moisture and mold to appear, resulting in dry or wet rotting.
The roof felts/tar paper should be applied to a dry, clean surface just after applying the sheathing. This will protect the felt from inclement weather. If the sheathing gets wet, it should be allowed to dry for 2 to 3 days. Thereafter the felts can be applied. It is important not to have any moisture trapped which may damage the sheathing.
Before you apply roof felt, be sure you establish which type of roofing you have. You will need to do this to be certain you have the proper application. To be certain that your roof will have a water-tight seal, it’s important to over-lap your roofing felt. Without overlapping the tar paper, small crevices or cracks could easily allow moisture to seep in.
