Replacing Flooring or Roofing over Radiant Heat

zmesh-under-woodOne of the selling points for our electric radiant heating systems is their longevity. In many cases, our low voltage systems will outlast your floor or roof! Today we thought we’d take a look at what precautions you can take while replacing your floor or roof covering with our products underneath.


ZMesh is a very versatile heating element and can be easy to work around when installing a new floor or shingles as long as proper care is taken.

First, the old floor or roof covering must be removed without damaging the mesh. Take care when pulling the nails from wood floors or shingles to not damage ZMesh, and do not cut carpet over the ZMesh. Additionally, the transition plates must be protected from damage.

Tuff Cable

For cable systems embedded in mortar or a similar material, it is often very difficult to replace the flooring without damaging the heating element. Tile should be removed carefully without disturbing the mortar bed, and then a new tile install can be done over the top of the embedded cable.

Keep in Mind

Some additional things to remember for any system:

  • Know where your cold leads are (the start and stop points that lead back to the control unit). If the heating element needs to be replaced, and the cold leads are in place and accessible, there is a great chance you will be able to connect new heating element to the existing cold leads and reuse the control units.
  • In flooring installations, you will want to keep an eye out for a floor temperature sensor. If your system has one you should avoid damaging it while tearing out the floor.
  • If the cable or mesh is damaged, a repair may be possible. Consult your installation manual for details on this process or contact our technical support team at Warmquest.
  • Always make sure to turn the breaker off before working on any electrical system.

If you plan to redo a floor or roof with a Warmquest system installed, give us a call first. Our trained experts can give you detailed guidance related to your specific system and project.

US Snow Infographic

Looking to move somewhere with ample snow? Or perhaps you are fed up with the snow the latest storm left on your driveway. We’ve put together this snow infographic illustrating some of the snowiest places in the country.

Looking for the major US city with the most snow? Syracuse, NY gets over 10 feet per year. Most snow in a single storm? Silver Lake, CO holds that record with nearly 8 feet. Browse the graphic for additional facts and data, then head over to our post on how much snow weighs and try not to feel overwhelmed.

Flat Roofs and Snow

ZMeshonMembraneFlat roofs come with their own unique challenges. In areas with regular snowfall, managing snow load and drainage is critical. While structural design is an important part of handling snow and ice, let’s take a look at some areas where radiant heat can play a role.

Snow Load

All roofs must be able to handle the weight of snow and ice, but flat roofs are particularly susceptible to snow accumulation. This is handled in many ways, and radiant heat can play an important role in preserving and protecting a roof.

To ensure snow never accumulates, the entire flat roof can be heated. Alternatively, large sections of the roof can be heated, lowering the total snow load and increasing solar gain as the sun works to clear the rest of the roof.


Drains are often used to keep flat roofs clear. As snow and ice melt, drains provide additional paths for water to run off the roof. This only works however if the drains stay clear and accessible. Adding roof deicing to areas around drains can keep them flowing all winter long. Paths can also be created for water to run to drains.

Snow Drifts

In some instances, snow drifts occur on roofs. In nooks and crannies, and shaded areas, these snow drifts can build up to the point where they pose a threat to the roof. Heating these areas is a great way to prevent drifting snow and ice and protect the roof. This case study reviews the installation of a deicing system to prevent drifting snow on a membrane roof.

Maintenance Access

It is not unusual for large commercial buildings to require maintenance access to the roof. In this instance, heating the roof can provide safe paths for employees to access critical areas.
