Polynum
My roofer says this is the best for lowering bills and general satisfaction.
What say you who have had it installed?

Electric, it is supposed to be superior to a radiant barrier.

Pretty much, yes.
I don't know anything about it and it seems we're not alone.

That sounds mighty familiar. Part of the big remodel project was a new roof. It is a 30 year roof with the ridge vents and IIRC that is what he called it. It's only been up about a month if that long. I expect if it's going to make a difference we'll be a celebratin' come August.

No, I think it is stapled under the roof decking, where a radiant barrier would be.

You would have known, since this is an expensive option, from what I can ascertain. I have this question on 3 forums and nobody seems to know much as of yet.

I'll soon find out.
I am totally clueless about this, thought I would ask on some forums, and so far nobody has responded. Don't know if that's good or bad, but I was wanting to hear that it was the next best thing since sliced bread and stuff.
Nothing....

If you are looking to lower your cooling bills, go with a white steel roof. It is the best radiant barrier you can install, and it is on the outside of your roof, not under it.
Attics with a white steel roof rarely get above ambient temps, even in direct sunshine. Shingled roof attics will get over 150 degrees on a hot sunny day. And they do not hold heat and bake your house for hours after sundown like a shingle roof will.
Steel will also last 3X longer than shingles.

I would love a steel roof, not only for the things you mention, but the sound of the rain.
Unfortunately my HOA doesn't share my sentiments.

It's kind of like plasticky-foil covered bubble wrap.
I haven't used that brand, but a similar one from Home Depot or Lowes. I've used it in my shed and in HVAC applications in a pinch. It's.... Okay.

Poking my nose around the Web, I don't think I would do it.
For the extra investment, I foresee it paying itself off in time to do the roof again.

A properly installed steel roof sounds no different than a shingle roof. You are thinking of a tin shed roof, not the same thing.
Your HOA is only about 30 years behind modern construction. A steel roof is a premium roof,. Some of the most expensive homes in America have steel roofs.

Some of the better builders in NV and AZ use something similar in new homes. It does make a quite difference.

I have some experience with several options. For my previous 30 year old house, I had the rafters sprayed with closed cell foam. I kept a record of electricity and after the form was applied my bill was 25-35% less than before the foam. More savings could be obtained by foaming the walls and adding double pane windows. Prior to the foam the attic could reach 140 in the summer. after the foam, the max was 110. The savings in electricity paid for the foam in 4 1/2 years.
In 2009 we built a new house. The external studs were 2X6 and foam filled after all electrical and plumbing was installed. Foil backed 1" foam board was applied over the outside of the house before the brick was put up. Foam was applied over the rafters. No insulation was put in the ceiling so the attic is conditioned. It never gets over 10 degrees more than the living area. Windows were double paned argon filled. I have 2550 sq ft living area and last month my electricity bill was $98.
Please note that my living area has no external vents. I do have a dehumidifier that keeps the house at 50% and there is external air feeds to the cooling system. Without the dehumidifier, moisture buildup could cause mold issues in a sealed environment.
I bought 100 ft rolls 4 ft wide of the foil backed bubble wrap at Home Depot for $40 a roll in 2010(I do not know what brand), and I stapled that in the attic of my garage on the bottoms of the rafters.(I now wish that I had foamed that from the start). I have a laser temperature gauge and if I point it at the sheathing that I could not reach, when it is 140, the bottom of the foil is 110. The foil stuff would work better if it was complete and if the roof had ridge vents.

I looked at the Polynum website. They are showing several ways to use their product. It is a radiant barrier and can be used in a variety of ways. They used it under the brick where we used foil backed foam board. Anything that blocks the heat will save you money in the long haul.
