Late last week the team from Oak Roofing worked on sealing the seams in the dome. Our water test showed that the dome was leaking at the seams. As a possible solution for the leaks, the dome's seams were opened and fused together.
The dome is made of lead. Originally the seams were folded over and pounded to a tight seal. This picture shows one of the seams fused together to create a solid barrier against water.
