Been in the roofing business 25+ years, but never heard of "Tech Shield". What is it? Some kind of underlayment?

Radiant barriers I understand. Be careful. If not well thought out, use of these products can cause an attic space to overheat.

Radiant barriers are very popular these days.
Many roofers suggest them.
Shingle manufacturers do not void entire warranties over them, but they don't like them.

The big question for most is:

Does the radiant barrier "absorb" the heat,....or "reflect" the heat?
A shingle manufacturer will answer....."It doesn't matter. It is doing something the the shingle was not designed for."

Hence...if the radiant barrier causes the shingle to age prematurely, it will probably not be covered under the terms of the warranty.

Thumbs up Tech Shield Rocks!

We installed Tech-Shield as our roof decking when we built our home 3 years ago. It is basically OSB w/ a silvery metallic coating on one side. That side is put towards the attic. It reflects heat back out to the exterior. Our attic is routinely 20-30F cooler than our neighbors' attics (so says the cable and A/C guys).

It does interfer w/ some cell phone reception if using a cell indoors. Also, you cannot put a TV antennae in your attic to catch free TV. You have to have cable or satellite to get TV, or run a free-standing antennae on a pole outside your home.

Lightning struck our home Friday 6/25. The electrical engineer said the T/S probably prevented a fire, as the metal dissipated the energy to the entire roof and down ground lines, rather than remaining concentrated in one point and starting a fire. Everywhere there is a nail poking thru or a deck clip, there is a char spot! We are in the process of contacting T/S to see if the integrity of the decking is comprimised for energy effieciency or future lighting strikes. We are very grateful for Techshield.

Radiant barriers do not void warranty. I cannot find a roofing manufacture anywhere, who will not warranty their shingle, on a radiant barrier roof.
The post says, roofing company. Maybe those roofing companies, need to be schooled on the profession.
