The NWT presents unique challenges: extreme cold (reaching -50°C in northern communities), very long retention periods (October through May—7+ months), and remote locations where building failure means catastrophic supply chain disruption. Unlike southern provinces where mid-winter thaw events shed loads, NWT snow compacts over months, creating enormous end-of-winter masses. Additionally, many NWT communities are fly-in only, making structural repairs logistically impossible mid-winter. Snow guards aren't a luxury—they're essential safety infrastructure. Systems must be engineered for both extreme cold (materials brittleness, fastener degradation) and persistent load conditions.
Can Canada Snow Guards ship snow guard systems to remote NWT communities?
Yes. Canada Snow Guards ships palletized orders to Yellowknife regional distribution hubs, and systems can be redistributed to remote communities via Arctic cargo carriers (First Air, Canadian North, Calm Air). For remote communities, planning is critical—place orders 4–8 weeks ahead of the June–September construction season. We coordinate with local band offices, municipal authorities, and GNWT procurement departments to ensure systems reach fly-in communities. For large institutional projects (government buildings, health centres, schools), our team can work directly with territorial procurement processes.
Which snow guard systems work best for diamond mine facilities in NWT?
Diamond mining operations (Ekati, Diavik, Gahcho Kué) demand the highest safety standards. We recommend bar snow retention systems for large-span processing facilities, equipment maintenance buildings, and accommodation camps. These systems handle extreme loads, resist cold-induced material degradation, and meet the engineered safety standards required by mine operators. Systems can be installed during mine site construction (summer/early fall) and function reliably through the full 8-month Arctic winter. Mining operations often engage engineering firms for snow load analysis—we coordinate directly with these engineers to supply engineered specifications and system performance data.
NWT Communities & Institutional Needs
From the capital to remote diamond mining camps, metal-roofed buildings across the territory face extreme snow retention challenges.

Roof failure = weeks without critical services. Prevention is essential. Cargo-dependent supply chains.
NWT System Selection Framework
Choose your snow guard system based on roof type and building class. All NWT systems must be engineered for extreme cold (-40°C+), persistent multi-month snow loads, and remote logistics.
Standing Seam (Institutional & Modern Commercial): GNWT buildings, hospitals, schools, modern commercial facilities. Metal clips bond to standing seams without penetration. Superior aesthetic and reliability. Handles compact, refrozen Arctic snow without degradation. Lead time 4–6 weeks.
Bar Systems (Large-Span Industrial & Mining): Diamond mine facilities, equipment maintenance buildings, large commercial warehouses. Heavy-duty horizontal bars engineered for maximum load. Fully engineered design available. Installation during site construction (June–Sept) critical. Coordinates with mine site scheduling.
Corrugated (Older Buildings & Modular Construction): Community buildings, storage structures, portable/modular buildings. Cost-effective, widely compatible, proven performance. Ideal for smaller communities and retrofits. Fastest deployment (off-shelf availability).
Contractors, GNWT Procurement & Remote Community Orders
Whether you're a general contractor managing institutional projects, a GNWT procurement officer sourcing materials, or a remote community coordinator building essential infrastructure, Canada Snow Guards offers streamlined ordering, bulk pricing, and logistics coordination. We work directly with territorial procurement processes, provide engineered designs for large-span systems, and coordinate Arctic cargo shipping to Yellowknife and beyond.
Northwest Territories Snow Guard FAQs
Does Yellowknife get enough snow to require snow guards on metal roofs?
+
Yes, absolutely. Yellowknife averages 143 cm of snowfall annually, but the critical metric is retention time. Snow persists from October through May—over 7 months. Unlike southern provinces where mid-winter thaw events shed loads, NWT snow compacts and refreezes into dense ice layers. By April/May, roof loads can be enormous despite modest annual precipitation. Snow guards are essential for all metal-roofed institutional and commercial buildings. Even small community buildings benefit from systems to prevent April/May shedding events and manage ice dam formation.
What snow guard system works best for NWT government institutional buildings?
+
Standing seam snow guards are ideal for GNWT facilities. Most government buildings (hospitals, schools, offices) use standing seam metal roofing. Our clip-on systems install without roof penetration, provide superior aesthetics, and handle extreme cold without degradation. They're engineered specifically for institutional applications with high occupant liability. We work directly with GNWT procurement and can provide full engineering documentation, performance testing, and installation guidance for large institutional projects.
How does the extremely long NWT winter affect snow load calculations on metal roofs?
+
The long retention period (7+ months) allows snow to compact and refreeze multiple times, converting it to dense ice and increasing roof load dramatically. Standard snow load tables (NBC) assume seasonal thaw events that don't occur in NWT. A modest 143 cm of precipitation, spread across 7 months of compaction, can equal or exceed 200+ cm equivalent of wet snow loads. This is why NWT buildings often have steeper roof pitches and reinforced framing. Snow guards must be engineered not just for initial snow load, but for compacted, multi-month accumulated mass. Our systems are tested specifically for these conditions.
Are bar systems required for large NWT commercial and institutional buildings?
+
For very large-span buildings (warehouses, processing facilities, major institutional buildings), bar systems provide maximum load capacity and redundancy. They're engineered for distributed loads across long roof sections and can handle the extreme masses at spring breakup. For medium-scale GNWT buildings, standing seam systems provide adequate performance with lower visual impact. The choice depends on roof size, load class, and building function. We recommend engineering analysis for buildings over 1,500 m² or in critical service roles (hospitals, emergency services).
Can Canada Snow Guards ship to remote NWT fly-in communities?
+
Yes, we specialize in remote logistics. We ship palletized orders to Yellowknife hubs and coordinate redistribution via First Air, Canadian North, or Calm Air to remote communities. Lead time is critical—order 4–8 weeks before June–September construction season. For community projects (government buildings, health centres, schools), we coordinate directly with local band offices, municipal authorities, and GNWT departments. Bulk orders for multiple communities can be consolidated for cost efficiency. Contact our NWT team to discuss your logistics timeline.
What snow load specifications apply to NWT buildings under territorial building code?
+
NWT follows the National Building Code (NBC) with territorial adaptations. However, NBC snow load maps may underestimate actual NWT roof loads due to the long retention season and compaction effects. GNWT buildings are often engineered with higher safety factors. We provide load analysis, engineering drawings, and code compliance documentation for all system installations. For major projects, coordinate with your building engineer to confirm load classifications and system specifications. Our team can review your building code requirements and recommend appropriate systems.
