I'm looking for advice regarding my intention to build/have built a deck on the flat roof of my single car garage. The garage is at the side of my house and access to the deck would be round the rear corner via a new balcony and french windows to our upper floor bedroom.
The garage walls are single brick with supporting pillars. The base is concrete and the roof is tarred felt.
Obviously once the deck is laid I will have no access to refelt.
Anyone got experience on doing this?
