Coatings Project Profile

Alamo Shrine

San Antonio, TX 

Completion Date: July 27, 2012 

Building Overview 

  • Attracting two to four million visitors annually, the Alamo is one of Texas’ most treasured landmarks.  

The Challenge

  • An engineer’s report in July 2010 stated that water intrusion in the roof was the “single largest threat to the continued viability of the Alamo structure.” There were three main challenges to this project: preservation of the existing main roof (standing seam copper, hand formed circa 1937) with all its character, restoration of the leaking flat roof areas, and rectification/waterproofing of the untreated parapet areas. The architect sought a product that would preserve the character of the existing roof while providing sustainable, watertight solutions for the other areas of concern, namely the flat roof areas and parapet walls. 

Solution

  • HydroStop™ PremiumCoat® System was selected as the most suitable and sustainable roofing/waterproofing product to restore the historic landmark. PremiumCoat® System is a liquid-applied, reinforced, water based acrylic elastomeric roof membrane that has been FM 4470 tested for water leakage, wind uplift, hail damage, flame spread, and resistance to foot traffic. The PremiumCoat® System was an ideal choice for the unique shape and structure of the Alamo Shrine roof. In a sense, PremiumCoat® acted as a “custom-fit” product, completely adhering to every curve while maintaining the historic “character” of the metal panels.  

Key Facts

  • To preserve the historic appearance of the roof, a custom PremiumCoat® Finish Coat color was tinted to match the color of the aged metal panels. Officially named Dover Grey, the color was nicknamed “Alamo Grey” on site.
