Crystal Clear Energy Saving, Mold Resistant Roof Coating for “Stay Clean” Metal and Concrete Tile Roofs

For over a decade, Syneffex™ thermal barrier technology has been lowering heating and cooling costs for homes and buildings in all climates and seasons.

Crystal is a thermal insulation coating that provides energy saving insulation, UV protection, mold and moisture resistance, it has also been tested to be resistant to the specific type of bacteria that causes the “black mold” streaks on roofs. Maintain the beauty of your roof simply.

Customers for over a decade report payback from energy savings in 3-5 years. Crystal has a 10 year worry-free warranty.

Use over sloped roofs: Tile, Wood Shingles, Asphalt Shingles (in good condition), Metal Roofs. FOR TILE ROOFS: Crystal can be used over “color through” tiles (have a matte, porous texture) but not slurry or glazed tiles (have a shiny surface). Can be used over flat roofs with good drainage.

4 reviews for CrystalShield™ Clear Roof Coating

  1. Customer Review Highlights

    “My neighbors actually thought that I had new tiles put on, but in fact coating with Crystal was just a fraction of the cost of re-roofing. There is no more staining due to mold, like my neighbors’ tile, which makes my roof a standout on the block.

    My total monthly energy cost is down a minimum of 17% to maximum of 42% year over year!!! I did not expect that much.”
    -E.Tyler, Niceville, FL

  2. Customer Review Highlights

    “I had my tile roof coated with the Crystal roof coating a few months ago and on my most recent utility bill I had almost a fifty-percent reduction, from $1,022 to $604, which was an amazing result! I was so impressed that I just ordered several gallons of the Home Protect to begin my interior wall and ceiling coating and I am looking forward to further reductions in my heating and cooling costs.”
    -Dr. B, Beverly Hills, CA

  3. Customer Review Highlights

    “Just wanted to let you know that I’m thrilled with how much warmer my house is this winter. I live in El Paso, Texas where the summers are brutal, and coated the roof in May with the Crystal coating to cut down the heat. But, I never thought about the difference it would make it the winter. Wow and Wow!!!! I am now truly a believer and will be coating the rest of the house (walls, etc) in the coming months.”
    -D. Benedict, El Paso, TX

  4. Customer Review Highlights

    “The application was put on a Spanish tile roof. Water will not penetrate and the [‘insulation’] properties are just great. The customers say the home is approximately ’10 degrees cooler’. I have looked into other ‘clear roof products’, none compare to the quality and warranties of the Crystal coating.”
    -V. Monisera, Rhino Roof Protection Systems, Palm Beach Gardens, FL
