Joe Barta. I figured that was the case but I wasn't sure. Thanks for the info. In a typical project like a housing tract, the roof is papered and roofing material stocked on roof to distribute the load to bearing walls before stocking and installation of drywall material.

It is typical for the roof to be in this condition for days while other phases of the construction are completed. Cold makes it brittle and wind can tear it. Shingles need to go on ASAP. Did I understand you to say that the roof sheeting OSB got soaked? That stuff flakes in pieces when it gets wet.

Pitch a fit and either get the roof in the dry or get those shingles on. AAJW Lazenby. When he begins to loose faith, there is hell to pay following. Building paper flapping in the breeze causes hairline cracks in concrete, causes out of plumb rough openings, causes warped studs, causes leaks in the plumbing, causes colors that are wrong , causes an unhappy camper!

A common misconception. Those tiles wouldn't hold out weather alone. They are there to protect the building paper from the sun, etc. Shingles are the same. On 31 May GMT, jba Ever wonder why shingle manufacturers do not require building paper under shingles?

My roofer has talked me out of installing it; his feeling is that in some cases building paper actually causes premature problems. Travis Anton. I gotta disagree as well we have left osb outside on site for months at a time the osb is coated for temporary weather protection. I've left it stacked and uncovered probably longer than I should have and never had trouble.

The only areas that "swell" are the cut pieces and even that would need more than one rainstorm. You shouldn't patch with osb at all it's junk Is synthetic felt breathable? Synthetic underlayment products are quickly increasing in popularity in the roofing market because they are stronger and lighter, and install faster than traditional felts.

Proper ventilation, not a breathable roof underlayment, is required to prevent moisture from becoming trapped in the roof deck. Can you shingle over wet synthetic underlayment? Do not shingle over wet or damp roof sheathing or damp felt paper. The trapped moisture cannot evaporate when the sun heats the shingle. Do not use caulking, roof tar or asphalt mixes to cover flashing materials. What is the difference between 15 and 30 roofing felt?

The difference between lb and lb roofing felt paper lb felt paper weighed 15 pounds per sq. Some customers prefer lb felt paper because it is a thicker product, less likely to tear, and should wear better over time. Can you roof over wet plywood? A: It is never a good idea to install a roof over wet plywood or any type of roof sheathing. Trapped water will boil when the sun heats the roof and the shingles will then have small pits where the steam finally escapes.

Can I walk on my tile roof? First off, we don't recommend that you walk on your concrete tile roof, if you can avoid it. Sure, concrete tiles are strong. But they're not really made to be walked on. Every time you walk on the tiles, you put stress on them that can crack them or loosen them. Do I need tar paper under shingles? Answer: Roofing felt is a layer of tar paper installed beneath the shingles to provide a backup waterproof membrane in case of leakage.

Felt, otherwise known as underpayment, is required when asphalt shingles are installed as a first layer of roofing or when they are applied over wood shingles or a built-up roof. Besides, the Bitumen or Asphalt element we know undergoes petroleum distillation, making the roofing felt waterproof. Waterproof felts often gives temporary protection from water while you incorporate tiles, roof coverings, or shingles.

Although it is beneficial as roofing felts are not designed to be a permanent barrier for water. Underlayment is established like shingles as we overlay the edges assuring each inch of the roof to be covered. It is not enough here to withstand the winter. Thus, a Roofing underlayment can get wet.

Shingles must not be placed over wet or damaged roofing felt paper. Also, if the roofing felt remains wet for long, it may have a chance to get rip while installing shingles. When the roofing felt gets wet, it acts as a shield more than the sponge due to the water repel property. The roofing felt absorbs and later repels water, administering the roof to sigh. But, if the surface beneath is wet, it may lead to the dissolution of the subsurface as well as the roofing felt.

When Roofing felt gets wet, one can cover it with shingles until and unless it is allowed to dry first. Bubbles or wrinkles can generate some heat pockets that can ultimately damage the shingles with time, meanwhile rips host an ability of Roofing felt to secure the roof. Roofing felt is designed to repel water, but one needs to install it correctly following the guidelines. If you wrinkle while installing, it can develop cracks, causing a risk of leakage. Also, watch out for holes and tears, if any, in the felt.

Remember to overlay the felt while installing it. If you have ever acknowledged roofing felt, you might know that roofing felt is used as the underlayment. High winds drive water or the snow over the roof or under the tiles of shingles. During that, an underlayment of waterproof roofing felt intercepts the water.
