but i have checked this out,no manufacturer of either vinyl siding or reflective foam mention this as a concern
I agree....I don't believe color or reflectivity has much bearing when installed in a location that is protected from direct sunlight.

I would be introducing myself and asking what they think about their roofs and other issues they may be having with their new house.

A quick update....

There really is no update! The builder is still dragging their feet on this. Over a month ago, they told me the temps had to consistently be in the 80's before they could even do an evaluation.

Well - it has been in the mid 70's to low 80's for a few weeks, and they still haven't come out. They either ignore my inquiries, or give me an excuse.

Attached are a couple pics. One is of my next door neighbors house. The house is 6-7 months old and as you can see - same problem. The house with the dirt visible is currently under construction. Again - same issues as my roof. This picture isnt the greatest as you can only see the horizontal lines because of the lighting - but the vertical lines are there. Trust me!

I will keep everyone updated when I learn more.

I think it's "lawyer up" time.


What you seem to be experiencing is a builder that knows there's a problem and doesn't want to deal with it.


Sort of like the EIFS stucco problems from a few short years back.


I bet this product will undoubtedly end up as the basis of many lawsuits as well....

It looks to me like this "Solarboard" is dimensionally unstable under heat load, and is expanding and buckling under same.

I would have used minimum CD Exposure 1 - 5 ply 19/32 Fir Plywood properly spaced on a home of this quality.

What you are probably going to hear is that this is normal and will not effect the performance of the roof, regardless of the fact that it looks like crap. I do not see a problem with the rafters, but maybe someone sees something that I do not. An out of plane rafter, or one that is not crowned would result in a swale running from eaves to ridge, not what we are seeing here.

Google "Solarboard, class action suit" and see if anything pops up.

I just went to Solarboards website and watched their video. I noticed a couple of things.

1. Their mockup has no underlayment or shingles on it.
2. The foil side goes down. That means that the reflected heat is being sent right back into the OSB and the shingles. To me, this is idiotic. Wood moves a lot under normal circumstances, why microwave it. The delta-T on the sheathing must be enormous, which leads to:
3. Notice in the short video that the guy nailing this product appears to be using gigantic nails, on the order of 20 penney. Look at the nail, its huge. Could they be trying to restrain the board against movement?
4. The product in the video has large MFGR Imprints on the back of the board. I dont see those on yours. Did your builder use "Its just as good as a Zerox" on your home made in upper Slabovia?

Finally, what is wrong with simply applying proper venting to the attic space to eliminate heat passively?

And finally, finally.

JUST BECAUSE IT IS ALLOWED BY CODE DOES NOT MEAN THAT YOU SHOULD DO IT. AND IT CERTAINLY DOES NOT MEAN THAT IT IS GUARANTEED TO LOOK GOOD. JUST BECAUSE YOUR FOOT WILL NOT GO THROUGH IT IF YOU ARE A 150 LB PERSON, DOES NOT MAKE IT ADEQUATE FOR THE INTENDED PURPOSE. CODES ARE BASED ON THE ABSOLUTE MINIMUM YOU CAN GET AWAY WITH.

This is an absolute shame. A brand new Beautiful house constructed of brick with a roof that looks like it is about to cave in.........nice.

Did the sheathing get wet before it was roofed? I've seen this several times. The decking gets wet and the edges will swell, dry and stay swollen. If you look the high spots are usually around the perimeter of the deck sheets with the top edge (the one that got the most water in it) swelling the most.

If my realtor tried to show me that home and I saw that, I would pass without a second thought. Maybe it is structurally sound, maybe it is not. But it looks ugly to me and I would see no reason to invest the time and effort to find out what the problem is when I could just go look at houses with normal looking roofs. That is the problem that you will encounter when you try to sell this house. I cannot believe the builder has continued to do that through multiple homes and not figured out a way to prevent it.

Agree wholeheartedly. The problem is people coming up with things that simply do not make any sense from a materials engineering standpoint, in an effort to achieve, or more appropriately, Claiming to achieve an increase in energy efficiency. There is also the ridiculous mind set of tract builders trying to gain an edge over the competition by using something that is allowed by code. They would be much better off selling the fact that they build a quality home, and it costs more to do so.As I already stated, If I was building a new home, the minimum roof sheathing on 24 inch center supports would be 5 ply minimum Fir Plywood, 19/32 thick.
