In May, the Alamo began preservation work on the roof of the Alamo Church. As one of the oldest buildings in Texas, the Church has gone through many changes.

During the Battle of the Alamo in 1836, the Church did not have a roof. In 1920, the Daughters of the Republic of Texas added the reinforced concrete roof.

“This work on the roof is very important,” Alamo Conservator Pam Jary Rosser said. “It helps us determine if the roof that is above the church today should continue to be above this 300-year old structure, or if another type of roof would do a better job at protecting the church for future generations,” Rosser added.

The crew began by removing the “membrane” of the roof, an outer layer made of hydro stop and rubber. Then, they scanned the roof and spray painted it to identify the locations of rebar, which will help them determine the corrosion rate within the concrete roof.

“This type of analysis has never been done before,” Rosser said. “Once we know the corrosion rate and the level of water infiltration, we will be able to determine the longevity of this roof.”

Even with preservation work like this, the Church remains open (at no charge) to the public during the Alamo’s operating hours. For updates on preservation work on the Church, follow @OfficialAlamo on social media or visit
