Tar Paper Facts
Hi, I'm Tim Carter and I want to talk about a little about tar paper and how it is a great weather barrier. Tar paper is being installed on the sides of the shed I am building.
Tar paper has been used for well over 100-years as a highly effective weather barrier. It is waterproof and work under any type of siding or brick. It will keep your OSB or framing dry from any water that gets behind the exterior finish. It is affordable and effective. Tar paper is time-tested and it works. Installation is simple and easy.
On other remodeling jobs where I have taken apart some of the exterior, I have found tar paper that is 80, 90 or 100-years old, it may be brittle now, but it is still water repellant. The wood behind the tar paper was as dry as the day the house was built.
Tar paper really works. There are some other newer weather barriers out there, and tar paper might not be the latest, but it still is worth a look on your next project.
Since tar paper is such an effective barrier to moisture, won't it prevent interior moisture from escaping? Isn't that the reason for the newer vapor barrier products?
Dear Mr. Tim,
Having been a commercial roofer for a few years, I love roofing felt! In fact over 20 years ago, I used it to protect the treated lumber on a raised bed. The bed is still good. An employee of a Big Box store was telling me his wife wanted raised beds and the wood decayed after a couple of years. I suggested he line it as wood doesn’t do well when subjected to damp soil. Folks would be aghast that I used the TSYP that is now not sold to the general public. But Texas A&M did a study many, many years ago and proved there was no leaching or at the most little leaching of the dreaded chemical. It’s unfortunate their study went ignored.
Hi Tim, I had a house built in Clermont County, OH in 1990. When it came to roof, I specified 30# Felt be put down under Roof. Builder said they didn't use Felt, just put shingles down on roof. Needless to say I had felt put on and when I had roof replaced, I had No damage to decking were as all other of the 38 + homes had to have many roof sheets, 1 - 12+ sheets replaced. Felt was a good investment. Bill
Great Resource. Looking forward to the newsletter.
