Here are the steps:
1. Install a fiber base paper directly over the stone with large washer plates sand screws
2. Install an SBS self-adhering modified Bitumen base over the Fiber Base paper
3. Install a Modified Bitumen Torch Down White granular Cap membrane
These types of roofs will last 40 years and beyond without shrinking or causing any leaks due to seam failures or any other reasons.
