We recently replaced the roof tile underlay ( waterproofing membrane) and battens on this old house in Winston Park.
Step 1: The roof tiles were carefully removed and pressure cleaned.
Step 2: Remove all battens, install new underlay and battens.
Step 3: Re-install cleaned roof tiles.
This project took approximately 5 days to complete. The roof was left water light at the end of each day, and the owner was allowed to remain in the house for duration of project.
