When installing new shingles on new sheathing or plywood are you supposed to remove the cellophane strip covering the tar on the back? Normally I do but have heard conflicting info lately. Does it matter for summer or below freezing?

Carson, you've been out in the sun too long. How long does it take you to pick that plastic off a bundle? Joe H
*Carson, the tar is there to help bond the layers of shingles together and make it more difficult for wind and driving rain amongst other things to lift up the edges and possibly damage the shingle and allow the elements to get to the sheathing. Yes remove any cellophane.
*Carson, are you putting the shingles down with no felt? Or does it just read that way? Joe H
*I have done some sheds without tar paper (felt) but what we are working on now has paper down. Does it matter as far as the cellophane goes?Carson
*you picked up on that too Joe? Carson what does the tar strip com in contact with? the shingle on top of it. although you should be using felt the tar is for the shingles and nothing more.
*Carson, I built a detached garage about ten years ago and I did NOT remove the strips, as per the instructions. Well....needless to say, the shingles are starting to curl up a bit and I think that had something to do with it. The roof on the house is over 20 years old and it looks great. From this experience, I think I would remove the cello strips if I had to do it again.
*Carson, the plastic on the shingles doesn't need to come off. Did you read the wrapper? There's a lot of info on those wrappers, but nothing about peeling off that plastic. If it had to be removed, don't you think they'd have used something a little easier to get off? Ever seen thousands of those things blowing around a building site? Here's a site that has some info re underlayment & why. Any search for asphalt shingles will turn up plenty of sites that will explain the whys of failures, but those plastic strips aren't going to cause curls or whatever. Bad nailing and staples are the most common reasons. Joe Hhttp://www.casma.ca/cas_tech.html
*ROTFLMAO!These guys are pulling your legs off!!!!!!!!!!Your shingles come with dabs or a strip of tar to seal them together after they are installed on the roof. This is to stop the wind from tearing them off. We used to have to dab roofing asphelt under each individual tab by hand in high wind areas or use T-Lock style shingles. Now the manufactureers do it for us. Now get this - That same strip of factory installed tar would seal the shingles together in the bundle so that you'd never be able to separate them to install. So they add a strip of cellophane to let them separate when you want them to. Folks who have torn it off every shingle to install them are one of the biggest jokes in roofing. Sorry you got caught, I'm sure you're just trying to do the best job possible.
*I couldn't hardly ever believe that people were really peeling this little strip off, but evidently enough were that Tamco has put it right on the wrapper to leave the strip alone.
*carson....wasn't that fun ?and boy is my face red... i think i did that once about 1975.... hah, hah, hah....those damn strips were in all the trees for blocks...
*Just in case there are any lingering doubts, here's an illustration showing why it's unnecessary to remove the cellophane.
*So there you have it...
*i are you supposed to remove the cellophane strip covering the tar on the back? I read this to say that the cellophane had adhered itself to the tar strip itself. then you would have to remove it. anybody care to argue the linguistics here?
*Sure. Around here, we don't get "cool" shingles like Elk. We get Certainteed or OC. The little cellophane strip says, in big letters every 3": DO NOT REMOVE. Easy enough, even for most of us posting here.
*Ok but if the cellophane had adhered to the strip the writing would be backwards and then it should raise a question.
*The cellophane IS on the glue strip. It stays there, it likes it there. Leave it there. How long does it take to do a roof peeling those things off? Joe H
*glues strip good tar strip bad
