Roof and Gutter De-icing
Prevent ice and snow buildup that can cause extensive damage to your roofs, gutters and downspouts. Read more to learn how to get heated gutters.
Freeze and thaw cycles create ice dams that can quickly damage or even destroy roof coverings, gutters and downspouts. Pooled water behind the dam may leak into the building, causing water damage, or climb over the ice-filled gutter, forming icicles. The resulting water damage to your home’s interior can be many times more expensive to repair than the roof or gutter itself.
How do roof de-icing cables and gutter heating cables work?
Warmup Roof & Gutter De-icing Cables offer the best solution to prevent these dangerous ice dams and icicles. They provide a continuous drain path for melted ice and snow from the roof through the gutter and downspout. And by using an automated snow and ice melting control, the cables will operate only when you need it, minimizing operating costs.
Versatile, reliable and cost-effective, these cables are the effective answer for roof and gutter de-icing applications.
How do I calculate the total amount of roof heating cable and gutter heating cable needed?
Length of roofline to de-ice = …ft
Zig-Zag on roof every 2ft and 2ft up/down
= roofline length * 2 = …ft
(Length x 2) x # of downspouts = …ft
(Add 3ft for in-ground spouts)
Add cable length for valleys (up/down)
Add cable length for dormers (around dormer)
What is the difference between the Self-Regulating Cable and the Constant Wattage Plug-in Cable Kits?
Warmup Self-Regulating Cable (NAMSR)
Self-regulating wires melt snow and ice to keep a drain path for water to flow freely away from the house from the roof and gutters.The self-regulating frost protection cables also work automatically to protect your pipes from freezing, bursting and causing damage from flooding. Suited for commercial use and residential with heavy snow fall.
Warmup Constant Wattage Plug-in Cable Kits (WRGH)
This cable prevents ice that can cause extensive damage to pipes. The 5.5W per linear foot, twin conductor heating cable, creates drain paths needed, enabling snow and ice to melt and drain freely. The resistance heating element has Fluoropolymer as a primary insulation covered with metal sheathing. It is UV resistant and environmentally friendly, making it ideal for outdoor use. Suited for light residential applications.
A full range of controllers and accessories is available, guaranteeing the optimal solution for all outdoor heating.
