Cold Applied Roofing Services

If your flat roof needs attention but you’re not ready for a full tear-off (or if you’re looking for a more cost-effective alternative to traditional roofing methods), cold-applied roofing could be the solution for you. At On Top Roofing, we install cold-applied roofing systems that stand up to harsh weather and protect your home for the long haul. Because this process doesn’t require heat, it’s faster and more budget-friendly than many other flat roofing options. So whether you’re repairing an aging system or starting fresh, we’ll make the process easy with quality materials and service you can count on.

Cold-applied roofing is a system that is installed without the use of heat. Instead of torching or heating materials onsite, we use specially formulated adhesives to layer membranes and build a watertight seal. It’s often used for flat or low-slope roofs since it provides a durable, seamless finish that resists leaks and weather damage.

Why choose a cold-applied roofing system?

No flames or hot asphalt

Cold applied systems don’t require torches or kettles, making the installation process safer and less disruptive—especially around vents or HVAC units.

Quick, clean installation

There’s no need for bulky heating equipment, which means faster setup and less mess. That’s good news if you need repairs done fast or want to minimize downtime.

Great for repairs and overlays

Cold-applied roofing works well for restoring older roofs without a full replacement. It can often be installed directly over an existing surface, saving you time and money.

Reliable protection

These systems are designed to be flexible and weather-resistant. They can handle UV exposure, ponding water, and seasonal changes better than many traditional roofing materials.

Budget-friendly results

Cold-applied options are often more affordable than heat-based systems. And with proper installation, they still offer years of dependable protection.

Cold-applied Roofing FAQs

What types of roofs are compatible with cold-applied roofing?

These systems are ideal for flat or low-slope roofs, like those on garages, sunrooms, porches, additions, or commercial buildings. If your roof doesn’t drain quickly or has ponding water issues, a cold-applied system can be a smart, durable solution.

How long does a cold-applied roof last?

With proper installation and routine maintenance, a cold-applied roofing system can last 15–20 years. Periodic inspections, especially after storms, help catch small issues before they turn into big ones, so your roof can potentially last even longer.

Can it be installed over my existing roof?

In many cases, yes. Cold-applied roofing is often used as a restoration system, meaning it can go over an existing layer if the structure beneath is sound. We’ll do a full inspection to confirm your roof is a good candidate if you want to go that route.

Is it safe to install around vents or skylights?

Yes, and that’s one of the biggest advantages of cold-applied systems. Since there’s no open flame or hot tar, we can safely apply materials around delicate features like skylights, chimneys, and HVAC equipment.

Does cold-applied roofing require a lot of maintenance?

Not much at all! These systems are built to be low-maintenance. We do recommend an annual inspection and minor touch-ups as needed, especially if your roof gets heavy snowfall or debris buildup.

How long does installation usually take?

It depends on the size and condition of your roof, but most cold-applied roofing projects are completed in 1–3 days. Since there’s no heating equipment to set up or manage, installation tends to move faster than other roofing methods.
