Heated Cables For Your Roof

How to Install Ice-Melting Roof Cables | Ask This Old House

Colorado winters are tricky. In an instant, the temperatures can plummet and the snow can begin falling relentlessly. While some places along the Front Range are worse than others, nobody gets off too easy.

One of the consequences of heavy snowfall and cold temperatures especially combined with the chance of the intermittent warm day can cause ice to build up in your gutters, forcing moisture under your roof and into your home.

Use Equipment Such As Cable Clips Zip Ties T

These supplies are typically available right through the cables manufacturer itself.

The actual installation process can differ on a case-to-case basis, which may also include special equipment and references that are specific to your chosen heating cable system. That is why you should only take these points as a general guideline and refer to the detailed manual that comes with your heating cable for further information.

Should You Install Heat Cables To Prevent Ice Dams

Heat cable has its place in the world, but I usually dont recommend it to my customers, for a few reasons.

Heat cable, heat tape, heat wiretheyre different names that mean the same thing. Theyre hot wires that run up and down your roof to melt snow and prevent ice buildup on your overhangs and in your valleys.

Heat cable has its place in the world , but I usually dont recommend it to my customers, for a few reasons:

Heat Cable Problem #1: Its often a Band-Aid.

Heat cable doesnt fix the root cause of the problem: too much snow on a roof thats overheated because warm air is leaking into your attic.

90% of the time that problem is fixable, and it all starts with a quality home energy audit from someone who understands insulation, ventilation, and ice dams. Youll probably be urged to seal up spaces where warm air is sneaking into your attic like around light fixtures, outlets, etc. These areas that allow air-leaks into your attic are called attic bypasses. Your energy auditor may also tell you to double down on your insulation, or to improve your ventilation, or both

Heat Cable Problem #2: Its an energy-drainer.

Even very good heat cable may add about 20% to your energy bill all depending on how often you power it on. Thats no better on your wallet than it is on the environment.

Heat Cable Problem #3: It melts snow that can just refreeze.

Heat Cable Problem #4: The warranty is a joke in most cases.

Heat Cable Problem #5: Its ugly.

Which Heat Cable To Use For Ice Dam Prevention

As I described in great detail in Part Two of my ice dam prevention series, there are only two classes of heat cable one can use for ice dam prevention: Constant Wattage , or Self-Regulating . We install Heat Tape Pro exclusively, but Raychem Winterguard is another excellent self-regulating heat cable our installers have used in the past. To a large extent, it doesnt matter which cable system you use as long as it is self-regulating and made by a reputable company. The limitations of constant wattage systems far outweigh their only advantage, cheap prices.

Ice Melting Systems For Roofs

Roof Heat Cable

After your roof accumulates a large amount of snow, sunlight and changing temperature naturally induce the thawing process for it. While the melted snow water easily travels down your roofing material to your gutter, some cold spots on your roof can often stop this melted snow in its tracks.

When this happens, the melted snow water freezes again. Over a short amount of time, this cycle can turn the frozen water into small ice walls or ice dams. Since these ice dams are made of solid ice, they are tough to break and problematic to keep on top of your roof.

Along with adding excess weight at the edge of your roof, these ice dams also stay true to their name and block melted snow water from passing through. This causes problems such as roof leakage and sagging from standing water.

With heating cables for roofs and gutters, you no longer have to worry about these walls of ice. After these systems are installed on your property, their emanating heat can prevent any ice dams from forming at freezing temperatures. From cold spots to water blockage, this system addresses all associated problems of ice dams in an effortless way.

What Are The Pros And Cons Of Installing A Roof Heating Cable

Had some roof work done last year after mother nature abused my house by way of an errant tree branch. I had always suspected my roof had poor ventilation, most notably when I wound up with a 200 lb chunk of ice going from roof to ground , so when the roofing contractor repaired the roof I had him install a ridge vent and ventilation system along the back wall .

Anywho to make a long story even longer, it’s winter here and I’ve got some ice dams in the gutters and icicles hanging off the roof. When spring rolls around I’m considering putting up a roof heating wire along the gutter and up the first 5-6 feet of roof on both sides of the house. I’ve heard various pros and cons from friends and family about these heating wires and just wanted to get opinions from the fine folk here as to what they think of this system.

I live in the “snow belt” region of Ohio . So if you live in a similar area or know someone who does I’d love to hear your point of view.

I’m a contractor in Maine and we certainly have a lot of experience with ice dams. An ice dam can be the quickest way to force water under the roof shingles even on a roof in good shape.

I have had mixed results with heat tapes. When they are used properly, they can be somewhat effective. Most folks expect to see a nice bare zig zag pattern along the edge of the roof with the ice gone around the tape. Not how it works!

Good luck with your project.

They Can Be Dangerous

Think about it you are putting heated pieces of wire on top of your roof. According to a Washington Post Safety notice citing a Consumer Product Safety Commission report, roof heat cables are responsible for around 2,000 structure fires every year and over 100 injuries. So are roof heat cables dangerous? They absolutely can be. But roofing safety isnt the only concern related to this de-icing method.

What Is Roof And Gutter Deicing And Why Do You Need A Heated Metal Roof

While metal roofs are usually better at handling snow load, ice dams, and icicles build-up, they are still not an alternative to a proper heating cable deicing system.

Ice and snow accumulating on the roof, inside your gutters, or in the metal roof valleys can cause costly water damage to your home or business.

WarmlyYours Ice Shield Roof & Gutter Deicing Cable System provides a reliable solution for ice damming that occurs on metal roofs, especially in the problematic areas like valleys, dormers or simply when the pitch is not steep enough.

How The Heating Cable Works

Heat Cable Installation | Colorado Roofer | Excel Roofing

The heating cable is usually used to protect the water pipe, drain line from freezing. Also, it is used for roof and gutter protection.

The heating cable has many layers such as an outer jacket, copper braid, insulation jacked, bus wire, and conductive core where self-regulating action takes place.

The conductive core is made of special plastic infused with millions of microscopic conductive electrical cells or pathways. At low temperatures, the core moves closer and turns the core into a resistive heating element.

Again, when the temperature is high, the core expands and lowers the temperature.

When To Call A Professional

On very tall homes with high roofs, the prospect of working many feet above the ground on an extension ladder may be unnerving. If you feel uneasy about this, don’t tempt fate. A nervous DIYer is an accident-prone DIYer. A roofing specialist or professional handyperson can do this work at an affordable price. Professional heat cable installation is also a good thing to consider if you are already having new gutters or new roofing installed.

Can You Put Heat Tape In Gutters

. Accordingly, how do you install heat tape on gutters and downspouts?

Run zigzags to create 15″ wide triangles, running the cable from the overhang to the warm area of your roof. Secure the roof cable with brackets, affixed to each shingle where the roof cable bends. Run the end of the roof cable along the inside of your gutter and down the gutter’s downspout. Plug it into a GFI outlet.

Likewise, how hot does gutter heat tape get? Lower power densities and temperatures, with maximum temperatures ranging from 150°F to 500°F, and including low-intensity cables well suited for freeze prevention. Higher power densities and temperatures, ranging from tapes with a maximum of 305° up to very-high-temperature tapes rated for up to 1400°F .

Also know, does heat tape work for ice dams?

Heat tape for ice dam preventionThe purpose of heat cable is ONLY to create relief channels through snow and ice, not to keep the eaves completely free of snow. When a high-quality cable is used and it’s installed by someone who knows what they’re doing, heat cables can provide a decade of reliable ice dam prevention.

Can you leave heat tape plugged in?

You can leave these models plugged in. The problem is that some people leave them plugged in for decades. Tucked away in a garden shed or crawl space, the tapes get hot in summer, cold in winter and soaked with moisture off and on year-round.

There Are Better Ways To Address Ice Dams

Perhaps the most important reason why roof heat cables are ineffective for preventing ice dams is that there are much better ways to prevent them. In most cases, ice dams are caused because heat is escaping from inside, melting snow on top of the roof and the melted snow runs down to a colder area of the roof and refreezes. Fixing these heat leaks is the most effective and beneficial way to prevent ice dams and lower your heating costs to boot.

Why Do You Need Heat Cable In Park City

Zig Zag Roof Heat Cables

Park City is one of the most incredible places to live, but our mountain weather causes many homes to develop ice dams.

Ice dams are caused by a constant thawing and freezing of rooftop snow that develops into ice on the eaves of a home.

Heat cable is one of the best ways to solve ice dam problems on a home.

As weâve shared so many times before, preventative measures are the BEST line of defense against ice dam buildup. And, consequently, theyâre also your best defense against the water damage that is almost sure to follow.

Since this won’t be our first wintertime rodeo, we have spent a LOT of time investigating how best to combat this recurring threat. And, we have an answer.

Roof Clips For Heat Cable System

The type of clip you will use for your roof and gutter deicing system will depend on the roof material on your home. The vast majority of heat cable is installed on standard asphalt shingles making the roof clip choice simple. The Grip Clip is the clip we use for all of our installations because it eliminates the need to drive nails or screws through your roof system. It also installs in about three seconds without the use of tools. We still use traditional nail-on clips for the installation of heat cable on rubber and metal roofs. Installers apply a dot of adhesive to the back of each clip before securing it with a nail or screw. We allow the adhesives to fully cure before installing the heat cable, a process that can take a few days or weeks depending on variables such as the roof material and the outdoor temperatures.

The Physics Of Ice Dams

Ice dams occur because snow and ice on the roof melt due to the home’s interior heat. When this mass travels down the roof, it freezes again as it reaches the colder exposed overhangs or eaves. Over time, the frozen melt-off can build up into a dam barrier that causes ice and water to back up under the shingles. Inside the home, the dripping water can damage the interior ceiling and wall surfaces. Additionally, the sheer weight of ice dams may damage the roof overhangs and gutters.

How To Install Metal Roof Deicing Cables

How to install Roof and Gutter Deicing Cables

The first step is to ensure that you have the proper length of cable for your heated metal roof. A WarmlyYours account manager can help you figure this length out. Then, make sure the roof, gutter and downspouts are free from debris, leaves, pine needles or any combustibles. Double-sided tape pads can only be applied to roofing materials at temperatures above 40°F .

When attaching cable in the gutter, use clips every 10 feet. For roof valleys, run the heating cable two-thirds of the way up and down the valley. Add this additional length to the overall cable length.

Add clips before and after each downspout. Because metal roofs may have damaging snow slides, it’s recommend to put in a single pass of heating cable up and down the seam to return to the gutter section below.

Install end seals and power connections before turning on power. The heating device should be connected to weather-resistant, non-heating leads.

After installation is complete, turn the circuit breaker on to give power to the cable. Standing water in the gutter should feel warm within one hour. Adding snow guards on the roof to prevent sliding of snow above can minimize other damages to the roof or gutters below.

What Is The Best Deicing Cable For Heated Metal Roofs

What is the Best Deicing Cable for Heated Metal Roofs?

There are two different kinds of heating cables for roof and gutter deicing systems: self-regulating and constant wattage. However, only self-regulating cable can be used for heated metal roofs because constant wattage cables are not approved for that kind of application.

So what is self-regulating heating cable? Its a unique and energy efficient type of heating cable that has a special conductive core between two bus wires. This core becomes more conductive during cold ambient conditions therefore the heating cable will increase its wattage per linear foot in response to the cold.

This feature makes it ideal to help protect the perimeter of your roof from ice dams and for keeping gutters clear of ice formations in the winter. This type of cable will also decrease its power output , in warmer conditions, when the higher temperature will make the special core less conductive, which helps limit wasted energy.
