Installing WarmlyYours Roof and Gutter De-icing System on a Slate Roof with A Concord Carpenter

If you want to know how effective the roof and gutter deicing systems from WarmlyYours are, watch this A Concord Carpenter review as he installs the system.


Rob Robillard, of AConcordCarpenter.com, is an expert installer of snow and ice melting cable systems that utilize electric heat to keep roof surfaces clear. Watch as Robillard takes us through how to install an electric roof and gutter de-icing system on a slate roof. By following his instructions, you can install your roof snow and ice melting cable system in no time.

I’m Rob Robillard from aconcordcarpenter.com, and today we're going to be installing WarmlyYours roof, snow, and ice melting cables. These are the cables, here, that you use specifically for snow and ice melting products. We're going to be installing it in a problematic area on this house, where there are ice dams and, as a result, there was some interior leaking and water damage.

What we've decided to do is, below this deck is a basement entry area with full access to electrical panel and stuff like that, and it's also an entryway. This downspout, here, goes down to a dry well. What we're going to do is we're going to run our snow-melt cables down through the downspout and come out into an electrical weatherproof box mounted to the house; under the deck, so it's out of public view. That way we don't have any cables or conduit showing and we also don't have to fish and break through the walls on the inside. That's what we're going to do. We're going to start to fish our wires down to the cable, come out to an electrical box, I'll show you that later, and then we're going to start to lay our saw tooth pattern on the roof. Let's get started.

OK, we're up on the roof, here, and I'm just showing you how I installed. I came up through the downspout here, right here, with the gutter heat cable, and I ran these aluminum clips with the special adhesive tape in the gutter. I did it about every eight feet, and I ran it all the way down. What we're going to do next is we're going to install the heat tape on the roof. I wanted to show you this right here, I don't know if you can see this, those marks were made by a hammer-claw. In fact, if you look closely, right here, the hammer-claw fits perfect. Some knucklehead was up here chipping ice on a slate roof to get rid of ice stands instead of doing it properly.

What we're going to do now is we're going to install these copper straps underneath the slate roof. All of these slate shingles have nails up here; and we're going to slide up and we're going to hook onto the nails with these slots that are on top of this, and that's how we're going to install our cable. Our cable will install in these clamps. I'm going to show you how to do that in one minute.

OK, coming down the dormer we have these clips right here. Then we go down and we start doing our zigzag pattern and then we run ourselves into the gutter. We actually put some of these clips into the copper gutter just to keep everything secure. Then it follows down this drain pipe to the bottom of the deck where we have the external weatherproof junction box where the power runs. It runs all the way down the gutter.

Up above, on this dormer here, you can see we've got the tapes draping over the side. We use these eye hooks and I'll show you what I mean right here. We use these eye hooks to actually get the heat tape over the edge and hanging into the gutter here. This is on top of the dormer. These shingles, it's not shingles, it's actually like an asphalt-roll roofing. It actually needs to be redone, it should be done in rubber; but for now we're going to make it through this winter with these heat tapes and probably end up putting rubber up here and then reapplying the heat tapes. This zigzag pattern actually runs about four-and-a-half, five feet, up to the slate, all the way up past this vent pipe. We originally were only going to go three feet and we decided to just do the whole slope and we'd just make up the difference. As far as overhanging, we decided to use a mechanical fastener as well. We used an eye hook just to catch it over the edge, to create that drip edge.

We just finished installing the WarmlyYours system on the roof. All the heat tapes are installed, it's all secured. The leads run down the downspout here, down below the deck, and we hid those wires below because that's where we’re going to put our exterior weatherproof junction box. The electrician is coming tomorrow, he's going to power that box up, he's going to make the connections for the heat tapes to that junction box. Then we're going to install the aerial mounted snow sensor and the thermostat. The two of them in tandem provide feedback to that controller we showed you, telling the system when to turn on and when to turn off.

It's a smart system, it doesn't use a lot of electricity, it's only using electricity during the event and when the melting occurs. In comparison, when you buy those cheaper heat tapes that you just plug in and it's got a built in thermostat, those things are on when the temperature gets low and they stay on. As a result, they subsequently burn out, and they use a ton of energy. This system does not. It's only using the energy when needed. I was really impressed with it, it's a high quality system, the materials are high quality, and the components are high quality. The service I got from WarmlyYours was great, as well. From start to finish, they helped me design this system. I provided them photographs and drawings, they laid it out for me. Because it's a slate roof it's a problematic installation; they provided these copper clips which slide under the slate roof and attach to the slate nails, and give you a mechanical connection, a secure connection, to mount the tapes to.

Really nice, and like I said, attention to detail all the way. I would recommend this. I've got some familiarity with the WarmlyYours systems; I've installed a very similar system in a sidewalk melt system, snow melt system. It's the same components, we're just doing them on the roof now. The cable's different, but it's the same components. Highly recommended, it's a system that's going to last a long time. If you’re just re-roofing and you have ice dam problems, and you install it when you put your new roof on, it's going to outlast the roof. If you have a slate roof like this, and slate roofs are designed to last 100 plus years, this is the system you want. It's commercial grade, it's going to last, it's a smart system and it doesn't waste electricity when not needed.

I'm Rob Robillard, you're at aconcordcarpenter.com, and we just installed a roof, ice, and snow-melt system by WarmlyYours. Take Care.
