Flat roof advice needed
I’m building a carport and breezeway in southeastern Michigan and I’m struggling with construction methodology and products for the proposed flat roof.
Flat roof? I know…Martin’s Ten Rules…But… I would like to use all this roof real estate. This roof will cover a substantial portion of my small urban lot and I think, in the future, this could be valuable space. A Small Deck, a Modular Green Roof, Potted Gardens, Solar Panels…
Lots of options show up when you search flat roofs on the internet. Overhangs & Gutters seem logical to me and would be similar to standard residential sloped roofs. Built-Up Curbs & Scuppers are common on commercial buildings. Built-Up Curbs & Scuppers seem more complex and expensive to me, would they allow for a wider variety of future uses?
I’m finding that EPDM and Torch Down Rolled Roofing are the most commonly referenced systems. I’m not thrilled with the prospect of having a black roof baking in the sun right outside my house.
Angled Sleepers or Sloped Rigid Insulation? Sleepers would seem to promote better drying. Insulation is said to provide a softer and more forgiving base for the roofing. A little Insulation would be nice, but these are unconditioned spaces.
Any thoughts or recommendations would be very much appreciated.
