Avoid This Costly Winter Prep Mistake on Your Metal Roof 🏠

WarmlyYours does not recommend installing de-icing systems on ribbed metal roofs. Ribbed and corrugated panel designs typically lack the flat surface area required to properly adhere standard mounting pads and clips. Without a flush mounting surface, heating cables cannot be safely secured to the roof structure. Always evaluate your roof profile and material compatibility before purchasing your de-icing cable.

WarmlyYours self-regulating cable is suitable for use on standard asphalt or wood shingles, angled cedar, tile or terra cotta, slate, flat membrane-type (rubber or EPDM) roofing, and metal roofing. For attaching, the same clips are used for both slate and cedar roofing. Always check local codes for approved methods of heating roofs and gutters.

Yes. Self-regulating de-icing cable can be installed on asphalt shingle, metal, membrane, tile, and wood roofs, and inside metal or vinyl gutters and downspouts. Mounting clips and attachment methods vary by surface, so tell us the roof type when you request your layout and we will specify the right hardware.

Two good reasons for this:  

1. Constant Wattage cables maintain a consistent heat output regardless of the surrounding temperature. Metal roofs, being highly conductive, can cause rapid temperature fluctuations which can lead to overheating and potential damage to the cable's insulation, potentially causing a fire hazard.
2. The UL approved installation method requires self-regulating cable for metal roofs.  If not installed per UL guidelines, there is no listing and thus no warranty.
