Is any one-roof style better than another?

A. The worst kind of roof style is the Spanish style flat roof with a raised wall around its perimeter. It is swimming pool waiting for the next rain to fill it. It works well in the southwestern states where the climate is dry, but not in Florida. We have a lot to them in this area. This kind of roof is designed with drains to allow for run off. Often times they are not maintained and they become clogged. Generally, basic, simple roofs are the best. The fewer breaks and protrusions through the roof deck the better. In addition, a steep roof does better than a low slope roof. Steep roofs shed water more quickly and dry out much faster. A rule of thumb for low maintenance roofing is, stay away from flat or very low sloped roofs, (0/12 to 3/12) minimize breaks in the roof; dormers, multi-level roof lines all require detailing, flashing and are opportunities for moisture to enter eventually, keep it simple.  more
