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

Case Study
Lihue Airport in Kauai, HI

Size: approximately 146,875 SF

Want More Info? Download our FREE  Metal Coatings  Guide  Lihue Airport, located on the Island of Kauai, had an aged metal roof with several leaks. One of their biggest challenges was they needed a roof system that would restore their roof while allowing them to continue normal, day-to-day operations. This airport is the primary airport on Kauai and the main gateway for visitors, so there could be no business disruptions or closures during the application process. The airport is open 24/7 and is occupied throughout the day and evening. 

A roof maintenance system was selected as the ideal building material to get the job done with the least amount of disruptions. They chose to change the color of the existing roofs to a custom color, deep jungle green, to match the vibrant and beautiful green scenery surrounding the airport. Lihue Airport was very happy with the outcome. (Click here for more information on colored coatings)

The roof coating system provided the Lihue Airport with superior waterproofing, excellent reinforcement for seams, a leak-free and monolithic roof membrane, and most importantly - there was no business closure or disruptions!

Challenge - Aging, Leaking Metal Roof
  • Aged metal roof with several leaks
  • Rusted sections
  • Occupied business
  • Custom colors needed
  • Multiple roof levels
Solution - AcryShield® Restoration System  
  • Superior waterproofing and reinforced seams
  • RustShield A120 primers used after rust was removed for protection against future rust growth
  • No business disruptions or closures during application
  • Custom tinted coating color matched to existing building scheme
  • Watertight, leak-free hundley_hardware32-resized-219

E.M. Hundley Hardware Company's building was an aging metal roof system, over twenty years old, that was revealing inconsistent nuisance leaks to the interior sales floor. IRC specified a National Coatings' AcryShield Roof Restoration System consisting of a localized, reinforced, two-coat, 100% acrylic elastomeric custom color coating system with polyester fabric reinforcement at all metal panel end joints.

"National Coatings makes this approach feasible not only with excellent coating products but also with the wide range of accessory products from rust-inhibitive primers to individual butyl caps to encapsulate the existing panel fasterners."

- Project Manager, Mr. Rob Worthing
