Restore your Metal Roof without an Expensive and Time Consuming Roof Replacement Project

metal_roof_image1-resized-600.jpgMetal roofs provide an excellent solution for protecting your buildings’ assets. However, over time, like most roofing materials, the grommets and sealants can break down and weather, causing leaks and rust to develop which weaken the long-term performance of the roof. You’ll have two options, replace the roof entirely (which will cost a fortune and take awhile to complete) or you can restore your metal roof with a Metal Roof Coating System.

FREE GUIDE: Metal Roof Coating SystemsNational Coatings’ Metal Roof Coating Systems restore and enhance the performance of your existing metal roof - allowing you to fix your current roof without tearing it off and replacing it. These systems have minimal steps/stages to ensure high performance. During the preparation process, all the rust is removed, next a high performance rust primer - RustShield A120 is applied to prohibit future rust growth from occurring. Butyl tape or caulk and polyester fabric is placed over all seams and screw penetrations to guarantee a watertight, durable roof. The AcryShield A510 is then applied as a base and top coat over the metal roof, providing superior waterproofing, longevity, brightness, dirt pick-up resistance, and protection against biological attack. The A510 base and top coat for metal roof substrates offer the following benefits:

  • High Reflectance
  • Durability
  • Long-Term Proven PerformanceNeed Help? Contact a Roofing  Professional  Zero Obligation
  • Seamless Waterproofing
  • Fully-Adhered Installation
  • Energy Savings
  • Prolonged Roof Life
  • Reduced Life Cycle Costs
  • Renewable
  • Low VOC 

The AcryShield A510 has been rated and approved by the following institutions to ensure you are receiving an excellent metal roof coating:

  • Exceeds ASTM D6083 requirements offering excellent tensile strength, elongation and wet adhesion.
  • Energy Star® Partner - Product in white, meets the Energy Star®guidelines for energy efficiency.
  • UL 790 Class A Rating

Seal and Waterproof with Butyl Tape Metal Roof Products

Posted by Nicole Gale on Tue, Jun 16, 2015 @ 08:30 AM

004Metal roofs respond extremely well to roof restoration installations. The metal roofs are initially installed by snapping sections of metal panels together, which are then fastened down with rubber grommet screws and finally all the seams are sealed with a sealant to create a watertight metal roof. Eventually, these seams wear down and begin to fail, leading to water penetrating the newly exposed seam, initiating the development of rust.

When restoring a metal roof that has been exposed to these conditions, National Coatings removes the rusted areas and uses a high performance rust inhibitive primer to protect the roof from any future rust growth. Then the roof is sealed and waterproofed with a butyl tape metal roof product to ensure a watertight building. This tape is 4-inches in width to provide complete coverage of all necessary seams on both edges of the panels. It has extremely high tensile strength, allowing the tape to stretch and expanding with the building, without breaking, ripping or tearing. The butyl tape used by NCC is polyester-reinforced for durability and consists of butyl rubber sealant for excellent sealing capabilities on edges and seams of metal roof panels. After the butyl tape is installed, a topcoat of roof coating is sprayed over the entire metal roof, covering the butyl tape. The building owner is left with a brand new, fully restored metal roof that has excellent waterproofing capabilities, reflectivity, strength and durability. This roof can be renewed in the future to prolong or avoid a roof tear-off indefinitely, saving the building owner a lot of time and money.

The butyl tape metal roof product provides these roof restoration systems with the following benefits:

  • Extremely Easy to Apply
  • Superior Adhesion to the Metal Surface
  • Instant Waterproofing
  • Long-Term Durability
  • Excellent Flexibility over a Wide Range of Temperature Fluctuations

RustShield Provides Superior Resistance to Corrosion on Metal Roofing

Posted by Nicole Gale on Tue, Nov 04, 2014 @ 09:30 AM
Metal roof substrates are very popular for commercial roofing because of their strength and ease of application. After some time, these roofs need to be maintained because the grommets and sealants begin to weather, causing rust to develop. Over time, the rust will weaken the long term performance of the roof, causing leaks and other damage to the substrate.

National Coatings has a lasting and durable solution to solving rust issues - RustShield A120, a high performance rust primer that inhibits the future growth of rust after it has been removed in the preparation phase of application. 
RustShield A120 is a single component, low VOC, water based rust-inhibitive primer. It is used over ferrous and non-ferrous metal surfaces to provide excellent resistance to flash rusting and outstanding corrosion protection.

This primer is ideal over:
  • Metal Roof Decksnasa-1
  • Metal Side Walls
  • Rail Cars
  • Pipes and Other Metal Equipment
  • Tank Exteriors
  • Structural steel
NASA chose National Coatings' RustShield A120 product to be used on their Ares I-X rocket due to its superior strength and ability to shield against rust. RustShield allowed NASA to maintain the rocket's exterior integrity while it passed through the salty air above the ocean before entering into Space.
