Seal and Protect Your Metal Roof

Why Does a Metal Roof Need Ongoing Protection?

Metal roofs are known for their long service life, which is why they're a common choice for commercial buildings. Even so, they face enough wear over the years that investing in additional protective measures can make a big difference in how they perform.

This is precisely what our fluid-applied roof coatings offer. They help keep moisture out while slowing the spread of rust and addressing existing corrosion. Without that level of protection, leaks can become more frequent and repairs much more extensive than they need to be. You don’t have to stop production to get started, either. We can complete the work while you and your team carry on beneath, keeping disruption to an absolute minimum.

How Metal Roof Flashing and Seals Deteriorate

Metal roof flashings and seals are constantly expanding and contracting as temperatures change through Southern Ontario’s increasingly extreme seasonal transitions. That movement can pull at seams and create small openings where water begins to work its way into the roof system. Left alone, those weak spots rarely stay small for long.

We start by repairing these vulnerable areas before the roof coating is applied. Seams, flashings, and roof penetrations are reinforced with high-strength fabric embedded in ASTEC® WPM #9 fluid membrane, or with the WPM #10 where the roof calls for it. This creates a continuous seal across the areas where leaks are most likely to develop.

Can Loose Roof Fasteners Cause Leaks?

Roof fasteners hold the metal panels firmly in place while helping the roof withstand movement and changing weather conditions. Every fastener plays a part in keeping the roofing system secure, so even a small number of failing fasteners can allow water to find its way in.

When loose fasteners aren’t identified, the surrounding areas often become more vulnerable as well. During restoration, we strengthen and encapsulate these critical areas. It’s not enough to address the fasteners alone, though, which is why this process is preceded by the necessary preparation work and followed up with the eventual coating application.

National Coatings Of Canada Inc: Invest in Metal Roof Longevity

We help businesses invest in roof longevity by addressing the problems cutting a roof’s service life short and restoring it before replacement becomes necessary.

We focus on the details that make the biggest difference, including:

  • Corrosion control before new coatings are applied
  • Sealing around fasteners, seams, and penetrations
  • Reinforcement in the areas most likely to admit water
  • Reflective finishes that reduce heat buildup on the roof
  • Coating systems matched to the condition of the surface
  • Follow-up monitoring that helps catch new concerns early

Why Metal Roof Coatings Require Attention To Detail

The quality of a roof coating comes down to the work that happens before, during, and after it's applied. It’s not just about the product or the system. Every fastener, seam, flashing, roof penetration, and finish coat has to be handled with care for the system to perform.

This is where our experience shines. We’ve been restoring commercial metal roofs since 2002, and our crews are trained and certified to apply leading fluid-applied roofing systems. We follow manufacturer-approved application methods every step of the way because that's what delivers the finished result our customers expect.

All commercial, agricultural, and industrial spaces especially demand a higher level of workmanship, and that's exactly what we bring to every roof we work on. Don’t settle for shortcuts when your roof deserves a proven restoration process.

How Many Layers Does a Fluid-Applied Roof Coating System Include?

A fluid-applied roof coating system isn't finished after a single coat. Each application has a job to do before the next one can begin. This comes back to our emphasis on meticulously attending to every part of the system and building on each progressive step of the restoration.

Once the roof has been prepared and reinforced, the first finish coat makes up part of the foundation of the system. A second application completes the restoration, producing a smooth, reflective surface that helps manage heat, resists moisture, and remains flexible as the roof moves through seasonal temperature changes.

Will Your Commercial Metal Roof Look Different After Restoration?

Your commercial metal roof will look different once restoration is complete because every stage of the process is designed to improve both its condition and appearance.

Some notable visual changes include:

  • A brighter, more uniform roof surface
  • Rust stains and corrosion addressed
  • Seams, flashings, and roof penetrations blended into the finished surface
  • Mechanical units and curbs restored to a clean appearance
  • A commercial roof that looks maintained instead of neglected
  • A seamless coating across the entire roof
