Are there any roofers here that can tell me how long your basic 30 pound roofing felt/paper can last exposed to the elements? I papered my garage roof over three weeks ago, and it has rained almost daily here in Illinois ever since. The felt is not torn, but it is looking a little worn and faded out. How long before it will loose its water resistant properties?
I was called by a homeowner. The home was 5 years old. Only had 30# on since new. Was still good. took the strips of and shingled it.
You have a long time to go.
Roofed a garage once with 3 year old totally exposed paper. And it Looked fine to me.
For five years the 30# felt was the only protection that roof had? Maybe I'll just skip the shingles, heck ...I might be dead in 5 years anyway
Lefty, 5 years really? thats nuts
A few weeks wont hurt it, anything beyond that and I would check daily. If its a new construction garage, I wouldnt be terribly worried... if its a reroof application, be more prudent with checking on it, you dont want to get your stuff wet!
Doesnt take much rain, wind, or sun to find a weak spot.
I myself would not shingle over felt that has been exposed to the elements for a prolonged period of time, but that is just me...
People were living in the house, that whole time. They paid as they went. The roof was the last thing they saved money for.
20 sq. cheap felt= $150.00, so why use old weather beaten paper.Shingle Mate is 200.00.
I said that is just me. I also replace drip edge with a new roof, and I have seen guys re-use metal vent, and all sorts of other things to save a buck. Again it is just me, but I believe that a new roof means the entire system is all new...I have thrown away plenty of rolls of paper in the past that got left in the truck on a late night , and it rained the next few days....once it is wet, it is rippled and I will not fight with junk...And also papered a few rofs that it rained over night , and I ripped off paper and re- papered it with new...
I guess that since I started using Shingle Mate paper I am spoiled,lol...it will lay flat in a few minutes in the sun after it gets wet...
