For the ultimate "Cool Roof" there is now available a new and innovative thermal protection membrane for tile or metal roofs called "Thermal Control Membrane for roof underlayment" (TCMRU).
This product is comprised of several layers of patented membranes and reinforcement scrim which rejects over 95% of the radiant heat which previously heats up the roofing tiles, then the roof deck, then the attic. TCMRU not only increases comfort and significantly reduces energy costs, it virtually allows the bitumen based tile underlayment to last forever since most of the heat changes direction before it gets to the black paper.
Close up shot of the dried and brittle underlayment paper. This can happen in as little as ten years. If you live in a sunny climate and are considering replacing your roof this is your opportunity to put in place a product that will pay for itself for the life of the roof.
Benefits:
- Lower attic temps mean less heat to be removed
- Less heat also equates to increased comfort
- Twenty five year warranty against product failure
- Installs directly over conventional bitumen based roofing paper
- Attic is significantly cooler
- Ducts deliver colder air
- Easily integrates with existing tile roof underlayments or when using a metal roof
- Extends the life of the bitumen impregnated underlayment

This photo depicts one building with TCM Roof Underlayment and one building without and there was a 28F difference in deck temperature and a significant increase in comfort. The effects are immediate and long lasting. This is the path to the "coolest roof" in a hot sunny climate.

Great for metal roofs!
Shown above is TCM Underlayment being installed under a standing seam roof.
The lateral lumber is used as a spacer to create room for the 500 feet of Pex tubing that was installed to act as a pool heater.
This same design can be used to create domestic hot water or for space heating purposes.
TCM is the ultimate method for rejecting infrared heat before it even gets to the roof!
