SPF roofing contractors, Central Coating Company fully restored two leaking metal roofs using an AcryShield SPF Roof Restoration System.

The Produce Packing facility located in Northern California was experiencing several common roof issues with their current aging metal roof. The roofs were leaking, had condensation build-up and some of the metal panels were weak and not performing as intended. They needed a watertight, cost-effective solution that would be good for the environment and provide energy efficiency benefits. With plans in the near future to add solar panels to the roof, the building owner wanted a system that would compliment the solar panel capabilities.

A Solar Ready, AcryShield® SPF Roof Restoration System

Central Coating Company offered them National Coatings' Solar Ready, AcryShield SPF Roof Restoration System as it checked off all their needs and provided them with additional benefits. The SPF System delivered excellent waterproofing, condensation control, durability and strength across the entire roof surface and an insulated barrier for the cold storage facility. The SPF coupled with the bright white, highly reflective roof coatings lowered energy usage and consumption costs for the building. These highly reflective coatings will also provide optimal reflection from the roof to the solar panels for increased energy savings. 

The Produce Packing Facility was very pleased with receiving a watertight, energy efficient, durable roof that eliminated the need for a metal roof removal and replacement. The AcryShield SPF Roof Restoration System also came with a renewable 20-year full warranty.

Restoring Metal Roofs with Roof Coating Systems

Posted by Nicole Gale on Tue, Nov 15, 2022 @ 11:44 AM


How Does Metal Roof Restoration Work?

Depending on the system that is best for your roof, some features may change but in general our metal roof restoration goes something like this... To ensure excellent adhesion and outstanding resistance to flash rusting, the RustShield A120 is applied across the roof field. All seams and fasteners are reinforced with butyl tape to provide a tight seal at these locations. For additional insulation, or custom slope, SPF can be applied. Then roof is then coated with a pass of our AcryShield base ensuring all components of the roof have been coated and protected. Next, a coat of AcryShield top coat (which can be custom tinted to match your building scheme) is applied delivering industry leading UV protection, longevity and brightness. These top coats are formulated for superior dirt pick-up resistance and protection against biological attack, such as algae and mold.

Failing metal panels are removed and replaced with new paneling to remove areas of weakness, leaks and rust.

Metal Butyl Seam Tape

The photos above show butyl seam tape as it is applied over every seam, nail, screw, joint, penetration, etc... delivering a long-lasting, superior watertight roof membrane.

End Results
You are left with a building that now has a fully protected, fully adhered, seamless, and watertight Cool Roof Membrane. These roofing systems (in white and light grey color) are loaded with high levels of UV blocking pigments that fight against early roof degradation caused by sun damage and UV rays, reducing your roof maintenance costs. At the same time, the UV blocking pigments reflect the sun’s heat away from the building and in turn, keep the air temperature inside the building substantially lower.

Metal Roof Process

In the photos above, the "during" shows a sand colored base coat to ensure the entire roof surface is coated and sealed. The end result is a bright white, highly reflective fully restored metal roof top.

Sustainable Metal Roof Restoration Solutions

Sustainable Metal Restoration final

National Coatings offers several roof restoration systems that allow building owners to restore their existing metal roof with an environmentally-friendly, cost-effective approach to solving your roofing needs. These systems provide an alternative to a metal roof replacement with half the cost and much less time and labor as well as several other added benefits.

A Cost Effective, Innovative Approach to Metal Roof Failures

Choosing a fluid applied roofing system to restore your aging, failing and/or leaking metal roof eliminates a roof tear-off completely. National Coatings acrylic roof coating systems have lower material costs and less labor intensive than traditional roofing options. Depending on the condition of your metal roof, your building can be fully reinforced or have customized reinforcement/replacement of weak areas and panels. These systems provide you with custom solutions for your roofs particular needs. 

Minimal Disruption to Activities Inside the Building

Our metal roof restoration systems allow you to operate your business as usual, with no loss of time to the tenants or occupants inside the building - allowing your business to stay open during application with minimal noise disruption and no harmful or strong odors.

Environmentally-Friendly and Sustainable

With the ability to renew your roof every 10-20 years, you can avoid a roof tear-off indefinitely; eliminating landfill waste and the additional costs associated with a roof removal and replacement project. Renewing your roof increases its ability to remain watertight while benefiting from a newly applied highly reflective surface.

Energy Efficient

The AcryShield roof coating line provides the roofing industry with some of the highest rated roof coatings for long term reflectivity and solar roof index (SRI). These top coats are specially formulated to lower energy cooling costs, provide superior UV protection against premature roof degradation and increase the overall roof life.

Custom Insulation

When choosing an AcryShield SPF Roof System over your aged metal roof, you have the additional benefit of custom insulation with R-values up to 6.5 per inch thickness with more thermal resistance using less material than any other type of commercial insulation material. This prevents transfer of heat, cold, sound and/or electricity - saving you more money associated with heating and cooling costs.
