Snow Melting for Asphalt Surfaces

To ensure optimal performance, snow melting heating elements should be installed so that they are consistently 2"-3" from the finished surface. For installations using pavers, the maximum thickness for pavers installed over heating elements is 2.5". 

Yes, you can retrofit a snow melting system into a preexisting driveway made of concrete or asphalt. You can do this by using an appropriate tool to cut properly spaced lines (or trenches for tire tracks heating) in the surface. Then you can place the the heating elements in the lines (or trenches) before sealing them with either hot asphaltic sealer for asphalt retrofits, or backer rod and expansion joint sealer (SikaFlex or similar) for concrete retrofits. Of course, you'll want to make sure this step is done in accordance with the filler manufacturer’s recommended procedures. Check out our snow melting retrofit guide for more information about this process. 

Yes, with a retrofit installation. The process involves saw-cutting 2–3" deep channels into the existing asphalt, embedding the heating mats into the channels, and filling with hot asphalt. This works best for tire-track layouts where only two strips need to be cut.

Full-coverage retrofit is possible but more labour-intensive. If your asphalt surface is due for resurfacing, adding snow melting during the repaving is the most cost-effective approach.

See our Retrofit Application Guide for a step-by-step walkthrough of a real project.

Yes. Asphalt is an excellent surface for snow melting systems. Heating cables or mats are laid on the compacted base course (or on a binder layer of asphalt) and then paved over with 2–3 inches of finished asphalt.

Important: Only electric snow melting systems should be used with asphalt. Asphalt is installed at temperatures up to 330°F, which would melt the tubing used in hydronic (water-based) systems. WarmlyYours cables and mats are rated to withstand temperatures up to 450°F.

Yes, snow melting works on all three surface types, but installation methods differ:Asphalt:

• Heating cables/mats embedded in asphalt layer
• Best for new construction or overlay applications
• Cost: $8–$18/sq.ft. installed
• View Asphalt Design Guide

Concrete:

• Cables/mats embedded in concrete slab
• Ideal for new driveways or complete replacement
• Cost: $10–$25/sq.ft. installed
• View Concrete Design Guide

Pavers:

• Cables installed in sand base beneath pavers
• Best retrofit option for existing driveways
• Cost: $12–$22/sq.ft. installed
• View Paver Design Guide

Pro tip: Pavers offer the most flexibility for retrofitting existing driveways. All three options deliver the same reliable snow melting performance with proper installation.

Yes—and often longer. A heated asphalt driveway eliminates the two biggest causes of asphalt deterioration: freeze-thaw cycles and chemical deicers. Without salt and plowing damage, the asphalt surface stays intact longer.

The snow melting system itself is maintenance-free and designed to last the lifetime of the driveway. WarmlyYours cables and mats carry a 10-year manufacturer warranty.

With an embedded snow melting system, both surfaces melt snow effectively. Concrete has better thermal mass (retains heat longer), while asphalt absorbs heat more quickly due to its dark colour. In practice, the difference in melting performance between the two is minimal when a properly designed snow melting system is installed.

Without a heating system, asphalt's dark surface absorbs more solar radiation and naturally melts snow slightly faster than lighter-coloured concrete—but this depends heavily on weather conditions.

Snow melting systems use electric heating cables or mats embedded in outdoor surfaces to melt snow and ice as it falls.How it works step-by-step:

1. Heating element activation: When snow/ice is detected, the control system activates heating cables or mats embedded in the surface
2. Heat generation: Cables/mats generate 50 watts per square foot (mats) or 12 watts per linear foot (cables)
3. Snow melting: Heat melts snow and ice on contact, preventing accumulation
4. Water drainage: Melted water drains away naturally
5. Automatic shutoff: System stops when snow event ends (smart controls)

Control options determine operation:

• Manual control: You turn system on/off manually
• Thermostat control: Activates when temperature drops below freezing
• Moisture sensor: Detects snow/ice and activates automatically
• WiFi control: Remote operation + automatic weather-based activation

Why it's effective:

• Proactive (melts snow as it falls, not after accumulation)
• Automatic (smart controls require no manual intervention)
• Efficient (only runs during snow events)
• Safe (eliminates shoveling and slip hazards)

System components:

• Heating cables or mats (embedded in surface)
• Thermostat/sensor (detects temperature/moisture)
• Control panel (manages operation)
• Power supply (240V or 120V, depending on system)

A heated asphalt driveway typically costs:

• Product cost: $12–$22 per square foot for WarmlyYours snow melting mats or cables
• Installation: Adds minimal time to a standard asphalt paving job — the mats lay on the binder coat before the top layer is spread
• Controls: $200–$800 depending on manual vs. automatic with sensors

Tire-track coverage is especially popular with asphalt driveways. By heating only two 2-foot-wide strips, you cut product costs roughly in half while keeping the driveway passable.

Heated driveway installation costs $8–$25 per square foot, depending on size, surface type, and system choice:

• Small driveway (500 sq.ft.): $4,000–$12,500
• Medium driveway (1,000 sq.ft.): $8,000–$25,000
• Large driveway (2,000 sq.ft.): $16,000–$50,000

Cost factors:

• Surface type: Asphalt is typically cheaper than concrete or pavers
• System type: Mats ($249+) vs. Cables ($229+) affect material costs
• Labor: Professional installation adds $2–$8 per sq.ft.
• Controls: Basic manual ($200–$400) to premium WiFi ($800–$1,500)
