Step 2: Apply sticky tape to the surface

After cutting and cleaning the indicated area, the border of the hole is taped with adhesive tape such as butyl tape. Remove any excess adhesive material and place it in the right location.

Step 3: Set the roof curb

Place the roof curb on the adhesive tape and make sure it’s properly attached. If not, use screws to secure it.

Step 4: Fill up the gaps around the edges with caulk.

Finally, apply caulk around the periphery to ensure a tight seal.
