Following an extensive research and planning phase, we decided the best option was to use the same coating product used on the New Orleans Saints’ Superdome. Quality, warranty protection and anti-skid properties were the perfect combination for what we needed.
To waterproof the entire roofing system, Sika’s EP Primer was used first, followed by 621 TC as a base coat, Reemat Premium as a reinforcing layer, and 621 TC as a top coat. An additional layer of 621 TC was applied and seeded with aggregate and back rolled for traction.
With a single component roofing product, our installers were able to work quickly and efficiently, installing the entire system under less than desirable conditions. The “moisture triggered” RoofPRO product ensured that the entire roofing structure was waterproof almost immediately after application. In an area like Seattle, this is critical since weather can be unpredictable and rain showers are common.
Sika’s single component system, which did not require the typical mixing and mix stations as other two-component systems, was something the Space Needle management felt set our single component product apart and made it the most feasible for the workspace restrictions.
The customized and innovative roofing system was fully reinforced and was accompanied with the installation of a compatible deck surface with texture supports for safety purposes. A primer designed to bond to the existing surface was added to prevent any roofing failures or leaks into the mechanical room, which sits directly below the roof surface.
With a dedicated Project Manager assigned to the Space Needle project, our all-female team worked methodically and completed the project well within the deadline. This project is a true testament to Nations Roof®’s support of women in construction.
