9” ZMesh is sandwiched in between two layers of ice and water shield and stapled to the roof decking.  Shingles are then secured with nails directly on top.  Nails can pierce the ZMesh as long as the nails do not come in contact with any other metal objects.  The ZMesh comes in 9” wide rolls and is rolled out over the area to be heated.  Heating at least 6” above the roof eaves is recommended.

No, because it is “paper thin” no roof buildup or construction alteration is required.  ZMesh is 1/32” thick and 1/6” on the fold back.  This is not the case with other types of radiant heat systems.

ZMesh is a 9” or 12” wide durable bronze heating element that resembles screen door material.  It is used to melt ice and snow off roofs and is listed to be installed under shingles to UL standard 1588.

ZMesh is installed under shingles for several reasons.  Heatizon offers a long term solution to winter roof problems and we believe in do the project once and do it right.  ZMesh is protected when it is installed under the shingles and in most cases will outlast the roofing above. Thinking long term we offer an invisible solution as well as the longevity of a system that will perform for the long term so the customer will never have to worry again about winter roof problems. To install ZMesh existing shingles will need to be removed by a roofing contractor so it can be installed on the sub-roof with a layer of ice and water shield over the top of the system before shingles are installed back over it.
