Tri-flex underlayment eliminates moisture intrusion through the roof thereby helping to prevent mold.

Monday – Starting to wrap the dome in Tri-Flex roofing underlayment.

Tues. — Did not start until 3:00pm. This part of the dome is the hardest part to deal with – it’s too hard to work from the top using a rope and harness and it’s a long climb up the ladders from the ground. However, the weather has warmed up and the temperature is 24°F.

Wed. 10:30am — Starting to apply Tamko ice and water shield membrane to cupola.

Wed. 4:00pm — Finishing up Tamko ice and water shield membrane on dome – just in time for rain that is forecasted for tomorrow.

Done! Even Tyvek on the Cupola.
