FLAT ROOF – Access Hatch
I have a mansard roof and want to install an access hatch on the top (flat) portion. Beats clambering up a 12:12 pitch. It has three layers of paper in a flood coat of tar, gravel over.
I am looking for good advice on how to build and waterproof the curb as it may be in standing water from time to time. I don’t want to make any holes I might regret until I settle this detail. Self-adhering membrane? What would you do?
