Drainage for flat roofs

[Alma G.]

I read that scuppers are easier to maintain and are a cheaper way to drain flat roofs versus gutters or interior drains.  Would like input from anyone else who knows or have experience with flat roofs, pls.

A couple of notes:  my flat roof has a slight slope to allow the roof to drain to a particular side of the house. This helps you avoid having to put gutters on all sides of the house which is cost prohibitive. If you dont have a slope or arent sure, maybe you talk to a roofer and/ or gutter specialist and start getting quotes for your options. they would have to look and let you know what you can do. I recommend cutting back your trees to prevent overhang if possible. those guys are more of a liability for dirtying your gutters and breaking off and destroying a gutter or your building in a storm. try to be proactive or it might cost you down the line more than tree trimming cost. Easiest step is to add gutter downspout extensions on all downspouts to draw water away from foundation. you need to check the grade on each part of the house to make sure that water will drain away and downhill if possible from your foundation. some add soil to the side of house to grade water away from house as well. thats all I got. I'm sure others have other input.
