Which is better, .... Rubber or Shingle for Semi-Flat Roof?
The Roof of my Family room is semi-flat roof and this morning we, the family found several small leaks streaming down from the the ceiling, due to past week's historic and rare massive snow storm, close to 3 feet.
We are aware of a price of Rubber is higher than Shingle, however because of semi-flat roof, I started to consider whether Rubber-Roof is more suitabable to the Semi-Roof?
One of neighbors told me, however that Rubber-roof has 'condension issue' that concerns me a great deal. In my guess, there is some moisture built-up between Rubber and insulation?
EPDM rubber would be the way to go. I prefer ISO insulation and it can be fully adhered or loose-laid over that. I guess, but don't know that felt could be laid under the insulation to prevent house moisture from causing those problems.
