1001 underlayments

Just took the time to read the Nov. issue of Roofing Contractor. In the back they did a layout of underlayment comparisons. I was reading through it with interest. Apparently, the manufacturers submitted the data themselves by filling out a questionaire>>>

I was talking to the manager of a supplier on Friday. He told me that the wholesale price of felt is dropping, but back in July and August when things were rapidly rising, their buyer thought he was being smart by stocking up. Now, with the slowdown the>>>

J.M. made the best shingle of all time, the Woodlands, which you cannot get any longer, and now they have discontinued the best lightweight underlayment of all time, Durabase, which is the most remarkable sheet I have used in years. I'm almost out of it>>>

Just spent $450. for 2 rolls of the breathable. Scheeeechh!>>>

Unless felt started dropping like gas, I'm paying $12 a square for IKO 30 lb. The last feltex that I bought was for the temp (base) felt on a 200 square house. I picked it up as needed three different times over 5 months as they had things framed. Pri>>>

Come down? Hopefully they'll stop going up!! TheRoofing God is correct. Been told those facts for years working for manufacturers before moving to distribution sales.

There have not been any new refineries built over so many years but nearly every e>>>

I am still waiting for the price of shingles to come back down.>>>

We had a long duiscussion on this on the old RCS.

I am still prone to vent my roofs thru the venting system, not the underlayment. I mostly require my felt to lay flat under comp shingles-- Roofers Select for immediate coverage. 30-lb. for if it sits for>>>

Don't mis-interpret what I fuss about all the time. I use felts and I&W both. I like I&W on the eaves as a back-up. But I never worry about felt tears or gaps as a rule. If it won't roll up a penetration tightly, I remove it if necessary so my metal is>>>

Same here OS. It's the new wave of roofers touting underlay which is also new. Where I came from, the roof was the ONLY line of defense and I had to know how to do it right.>>>

Tinner, we nailed on thousands of squares of shingles with no felt years back. FHA specs used to be just one or two courses along the bottom of the roof. I remember when there was a "shortage" of felt and you could only get about 10 rolls of felt per>>>

I saw the same article, EGG. I noticed that Monier/Lifetile had their own synthetic. For years they insisted they would be neutral as to organic vs synthetic felts. I bet they're not so neutral now.>>>

Does anybody remember that the old 15 year asphalt/rag shingles were good for 18 years avg. with or without any underlay??????? It was only dependant on installion technique. Interesting.>>>

All the reps tell me it's important that no holes get in the materials so the roof won't leak. Seems they have no confidence in their asphlt roof products. 2 rolls of GAFDA came in for me. I'll try them under 2 copper roofs I'm doing.>>>

Definitely not .04. I would think not even 16, either. This is a question that deserves more attention than I have thrown at it but I'm wondering what the goal is actually if we have to ventilate anyway. What's the point other than the fact that kno>>>

It was indeed "interestin". One of the few mags i amy keep for reference. But still, what is the magic perm number?>>>
