Why Not???


I am a contractor, but not a Roofing Contractor. So I know nothing and that's just it. But for those of you who are, please comment on the following:

Is there a chemical compound that can be sprayed or rolled on a composition shingle roof that will waterproof and give good reflective qualities and reliability. (old roof but not yet leaking). Now I called Henry's and with their best sarcastic tone said, "No such thing." Now my question is, "Why Not"--it would probably sell well! We put a guy on the moon... or several of them and yet we can't do this? Or is there one? If so please recommend!

2nd question: for rolled roofing, what are some of the better compounds to use for waterproofing... what brands?

Thank you, Anchorite

Re: Why Not???


Is this a serious question? There are several coatings available and im sure a few would work.

However for starters it would look like dog

2 shingles shrink as they age and I feel that any coating that didn't look like pig slop smeared on the roof would crack in short order

Re: Why Not???


Roof coating flashing details are typically comprised of mesh and fibred coating. How do you think that would look on walls and facia

There is a product for coating Sheetgood substrate much better idea than coating the shingles.

Most people call it a tarp. Ha ha. It would be a big waste of money and create a terrible mess but I imagine you could hot mop it with asphalt. That is what the shingle are made of anyway. Woud look terrible and I bet would still be expensive.

Thank you, Anchorite
For shingles you have too many requirements. Particularly "reliability".

There is elastomeric roof coating. This is basically rubberized paint. The problem is that a shingle roof is a lousy candidate for any coating. Way too many voids and surfaces and irregularities. The "skin" only works if it maintains its integrity. Cracks and holes and weak spots would be close to impossible to avoid. Water that finds its way under the skin would have a hard time finding its way out. This would be bad.

Part 2

I assume you are asking about coating on an existing rolled roof. The elastomeric product might be a reasonable consideration for rolled roofing, so long as the "skin" can be established without compromise.

Coatings on 99.9% of roofs is like makeup. Looks good when you put it on, after a short period of time, it all comes off, looks worse than it did before and never did fix the problem.

Re: Why Not???


Look up Conklin Roofing products. We've used a lot of this projects to coat aged, rusty metal roofs with good success. Buys you another ten years of roof life leak free at a much cheaper cost than new. I believe they can put this over other substrates?
