It is safe to walk on.

Is it ok for roofing felt to get wet. So yes roofing underlayment can get wet. However when the rainy season is here we make sure to work quickly efficiently and safely. The decking sheathing should have been tarped and work stopped as soon as it was evident enough rain was going to fall to wet the wood or water barrier felt. Keep the roof dry more or less until the shingles go on.

My concerns with wet or damp felt is that it causes the felt to wrinkle. Most is made of paper by the way helps. Serves as a moisture barrier of sorts and it provides a. The felt helps ensure water drains off the roof after a storm.

If the sheathing or wood is wet during the time of installation it can trap moisture inside of your roof leading to mold rot or other severe problems. Doesn t matter at all. Roofing felt should ideally be dry when shingles are installed to avoid ripping but it s still possible to install when wet. During clear 70 degree days we have more flexibility in our schedule.

This can be unsightly and disturbing to the home owner. Roofing felt applied over a wet roof deck or shingles applied over wet roofing felt traps a layer of moisture within the roof. This shortens the effective life of the shingles and can adversely affect the roof sheathing. Roof felt gives your roof a better appearance and will help it last longer.

Roof replacement is expensive. Having wet sheathing covered with tarpaper or membrane will trap the water in the sheathing very bad practice and contrary to industry standardss for roofing. A wet installation can also cause a new roof to fail. That s why planning is so important during a roof installation.

These wrinkles can hold up the shingles from laying flat till the moisture evaporates. Any moisture trapped in the roof will flow down and out. Moisture should evaporate between the shingles and the felt and not cause any issues or damage any of the roofing products. Roofing felt is not designed as a permanent exterior barrier against water.

Roofing felt that has gotten wet can be covered with shingles as long as it is allowed to dry out first the surface underneath did not get wet and it did not wrinkle bubble or rip. This moisture can lead to mold and mildew forming underneath the shingles. The bubbled felt can cause a minor lump on the finished roof depending on what sort of roofing you re using. But not for long periods of time.

Shingles and roofing materials may not adhere properly to slick surfaces with high humidity. The felt can be damaged if exposed to moisture too long.
