Corrugated Metal Roofs

This photo shows a HotShingle installation. Again, HotShingle is installed on all new construction and new roof projects. The roof material installed here was asphalt composite shingle, however, the material could have been standing seam metal, corrugated metal, pro-panel metal, wood shake, cedar shingle, synthetic shingle (DeVinci), slate shingle, etc. The key is HotShingle easily installs on any roof edge if new construction or a new roof is being installed. It is NEC (Article 426) compliant since the heat trace cable is partially exposed for inspections, maintenance, and replacement! It heat a roofs edge on a continuous basis using a single heat trace cable as seen in this photo. This is a high snow load region and because all HotEdge designs rely on direct heat transfer, 90% of the time a HotEdge design will prevent ice dams and icicles from forming using a single cable! This is a fraction of the heat trace cable needed for other concepts which rely on indirect heat transfer.

This commercial building is located at 11,300 foot elevation. Ice dams used to be a hazardous reality for this property and leaks would result. Installed on this copper standing seam metal roof is HotValley and the HotEdge Rail. As you can see, ice dams have been eliminated and the small icicles visible are from years of damage to the roof caused by using manual methods to remove ice.


Two products are shown in this photo which are often necessary to manage snow pack on all low sloping metal roof edges; (1) continuous edge heating product and, (2) snow retention. Without snow retention system, snow-pack would continually slide to roof edge and hang off roof edges eliminating the benefit of a continually heated roof edge. Without a continuous edge heating product, ice dams and icicles would develop below a snow retention system. HotEdge is a single source manufacturing company for both products.


This photo shows Hotvalley and HotDrip performing on standing seam metal roof in high snow load region of the Rocky Mountains. Critical melt path in valley are maintained to prevent problematic ice build-up.


Because of all the factors contributing (high steep slopes, wind blowing snow, and high elevation) to major compaction issues in the wide valley on this commercial property, two HotValley runs were installed.


This photo show the importance of a two part roof ice management system; snow retention with the HotEdge Rail. Without the snow retention, snow pack would migrate and hang on the roof edge mitigating the performance requirements of the HotEdge Rail and ice dams and icicles could develop. Without the HotEdge Rail, ice dams and icicles would develop below the snow retention system. This is true for most low and medium sloping metal roofs.


This photo shows a common roof design which is very problematic in high snow load regions. Snowpack will slide from the upper standing metal roof as it was designed to do however once it slides into a lower sloping roof problems begin. To prevent problematic ice to develop on the lower sloping lower roof, HotSeam was installed to eliminate 100% of snowpack on the lower roof.


This close-up photo of a HotSeam installation shows how commercial grade heating cable is routed and secured and compressed against existing metal panels to prevent the accumulation of ice and snow-pack.


Always barely detectable on all metal roof edges, the HotEdge Rail was installed here to prevent ice dam and icicle problems. Also often necessary on metal roofs is a snow retention system. HotEdge provides both systems.


Shown here in this photo is HotSeam and HotFlashing installed to prevent damaging ice buildup against roof wall and on a standing seam metal roof where commercial windows are below. HotSeam can be installed to prevent 100% of snow pack on a roof deck as was the objective for this commercial property.


HotDrip was installed on the roof edge of this commercial hotel in the Rocky Mountains to eliminate icicles and ice dam formations. HotDrip creates a metal edge for heat transfer from commercial grade heating cable where a roof edge did not exist.


HotSeam was installed on the roof edge of this mountain condominium property to partially prevent ice dams and icicles from forming. With long fascia boards it is possible to extend the HotSeam sticks to prevent snow melt water from re-freezing on fascia boards.


The objective for HotSeam on this project was to maintain 100% elimination of problematic snow-pack and ice that would build behind the dormer structure. Without HotSeam, a glacial like block of snow-pack/ice would slide into the backside of the dormer during spring melt causing damage and leaks would result.


If you view this photo closely, it might cause a degree of confusion. Beneath the snow retention system, the end cut of an aluminum metal track is visible. HotEdge was asked by the customer to remove the failed aluminum metal track system and install the HotShingleLOK on the roof edge in it’s place. Please do not mis-understand. Aluminum metal tracks work, they are just plagued with high maintenance cost and higher energy bills. That is what happened with this metal track on a high profile commercial building.


HotSeam was installed on this standing seam metal roof with the objective of 100% elimination of snow-pack and ice in this high snow load region. In this particular application, the homeowner did not want snow-pack on this portion of his roof.


Special order HotSeam was installed on this curved standing seam edge of a building on campus at a University. Hazardous snow-pack/ice would accumulate on this roof edge and pose a risk for everything and everybody below. That problem and liability has been mitigated with the HotSeam system.


HotEdge Rail was installed on the edge of this corrugated metal roof. Sufficient heat transfer exist between the compression of the commercial grade heat cable and the edge wave to prevent ice dam and icicle formations without modifications and with a single heat cable.


This location is in a very high snow load region where the HotEdge Rail was installed here on the edge of this pro panel metal roof edge to prevent ice dams and icicles on this iconic commercial property. Snow pack on a roof insulates travelling snow melt water until it reaches the roof edge. Without the HotEdge Rail, the snow melt water would re-freeze and ice dams and icicles would develop. With HotEdge Rail, ice dams and icicles are eliminated.


HotDrip was installed on the edge of this standing seam metal roof edge to prevent ice dam and icicle formations. Like most metal roofs, snow retention stops were needed to prevent snow pack from continually sliding to the roof edge and hanging there. HotDrip without snow retention; ice dams and icicles would develop. Snow retention without HotDrip; ice dams and icicles would develop. Combining the two systems on low sloping and medium sloping metal roof edges is the most effective combination to manage snow-pack on a roof.


HotEdge Rail was installed on this standing seam metal roof edge to prevent ice dams and icicle formations. HotEdge Rail was the first HotEdge system to be UL Listed for safety and compliance. HotEdge systems remain the only roof edge ice melt systems available to receive a UL Listing.


This photo show low profile and UL Listed HotEdge Rail installed on edge of standing seam metal roof to prevent snow melt water from re-freezing on the roof edge where ice dams and icicles typically develop. The heating cable is always partially exposed to comply with NEC standards and earn a UL Listing for safety and compliance.


This photo show HotSeam installed with snow retention system to manage snow-pack and prevent ice dams and icicles to develop on this edge over a walkway at a regional airport property in high snow load region. The snow retention system protects the commercial grade self-regulating heating cable that crosses over from HotSeam to HotSeam from snow pack migrations to the roof edge. If a gutter system existed, the heating cable would not crossover as shown in this photo and instead it would crossover in the gutter trough.


If you look closely, you will see severed ends of standing seams above the performing HotShingleLOK product. Although this is not typical since all our systems easily retrofit to all types of roof edges, the customer of this commercial property requested that we remove previously installed aluminum metal tracks to install the more energy efficient and reliable HotShingleLOK system.


This photo shows HotShinglePRO4X performing on a corrugated metal roof edge. It is important to note that in 90% of the applications, 2X, 3X, and 4X are not necessary to prevent ice dam and icicle formations. This customer requested 4X to achieve the visual of maximum melt back regardless of energy requirements.


HotDrip installed on this standing seam metal roof edge. HotDrip houses a commercial grade self-regulating heating cable and transfers heat to the HotDrip edge where snow melt water cannot re-freeze. Without HotDrip, snow melt water would re-freeze on the cold roof edge and hazardous ice dams and icicles would develop.


HotMetalPRO2X installed on a standing seam metal roof. Like all HotEdge systems, commercial grade self-regulating heat cable is partially exposed making it accessible for inspections, maintenance, and replacement. This detail qualified our systems to be UL Listed; the only roof edge ice melt systems in the USA that are UL Listed for safety and compliance.


This photo shows HotShinglePRO3X performing. Please know, for a more finished or custom look, HotEdge manufactures a HotCap that is installed on corners to conceal commercial grade self-regulating heating cable as it transitions from 1X to 2X, etc. Heat cable can be seen in this photo because customer did not have a need to conceal heating cable between transitions.


UL Listed HotShingleLOK can be seen here in this photo preforming in a high snow load region. A single run of commercial grade self-regulating heating cable is able to achieve this level of melt back to do a patented raceway design housing the heating cable.


Crew installing HotShinglePRO on this hotel property in a high snow load region. HotShinglePRO and all HotEdge systems are UL Listed for safety and compliance. The chief reason HotEdge systems are able to achieve a UL verification is because our designs allow for inspection, maintenance, and replacement of the commercial grade self-regulating heating cable.


Copper HotShinglePRO is being installed on this mountain home. Because copper is a softer metal than steel and aluminum versions of the same product, you can notice a small level of “oil canning”. Although this will not impact system performance towards eliminating ice dam and icicle development, it is a characteristic of the copper appearance which we need to disclose.


HotShingleLOK2X is shown in this photo performing. Although it appears that a small ice dam has developed, if examine closely, a pathway for snow melt water exists between the ice and asphalt shingle for snow melt water to safely reach the gutter system. It should also be understood that HotEdge systems are able to melt further up from a roof edge than any other market alternative available. So if the belief is that ice can develop above a HotEdge system (since this photo shows it), then the same is true to a greater extent (since HotEdge systems are able to melt back further) for all other market alternatives.


In this photo, HotFlashing and HotShinglePRO are shown performing on a commercial property. It was important that a system be UL Listed for safety and compliance.
