Title of Question: Rooftop deck railing

 

Name: Janet    City: Toronto

Question: We are planning to build a rooftop deck. First, the roof needs re-roofing to correct a water pooling problem. For the decking material, we would like to use light weight decking tiles. My question is, how is a railing attached if it cannot permeate the roof membrane or be attached to heavier decking material (a safety railing is needed on 3 sides).
