It sounds good. You’re getting a new roof, so why not scrape off the shingles, put down roofing felt, a radiant barrier foil and the shingles right on top. What an easy way to install a radiant barrier, right?
The answer is NO. You just wasted time and money for no additional benefit.
Radiant Heat by is electromagnetic radiation that travels in a waveform across a void, either an air space, gas, or a vacuum. Without this space you cannot have radiant heat. If no radiant heat exists you can’t have a radiant barrier.
I keep hearing of some roofers starting to push foil products installed between the shingles and the roof deck as radiant barriers.
If you are getting a new roof, beware of roofing companies who are selling radiant barriers under shingles. Radiant barriers without an air space don’t exist. They laws of physics always apply. [No Air Space = No Radiant Heat = No Radiant Barrier].
What do you do if you are re-roofing and want a radiant barrier? There is a way to incorporate radiant barrier foil into a re-roofing application. The only way is if you can create an air space on one side of the foil. There are several types of roofs that have an air space between the roofing material and the roof deck. Barrel-type tiles, or roofs installed over wood battens, which create the needed air space.
With these types of roofing systems, a radiant barrier can be incorporated easily and economically. It is also recommended to “notch” the battens or leave spaces between the battens to allow for more airflow between the roof deck and the roofing material.
This method of installing a radiant barrier is low cost, and very effective in reducing heat gain into the home. Plus, it is profitable for the roofing contractor. Homeowners will appreciate saving money and having a radiant barrier installed the right way.
