If you are planning to add a new roof to your home or shed, be sure to consider all the available options. Pitched roofs come in a variety of styles, such as gable, cross gable and hipped, all of which are sloped to different degrees. Flat roofs have no slope, and are available in built-up, single-ply and sprayed polyurethane foam designs. Consult with a roofing contractor to determine which roofing option is best for your individual needs.
Both flat and pitched roofs require regular maintenance. However, although pitched roofs may be more difficult to clean and inspect, due to the sloped structure, flat roofs often require more maintenance throughout the life of the roof. Flat roof drainage is not quite as effective as a pitched roof's, and without regular inspection, drains can become clogged, leading to damage and leaks. The roof requires a waterproof seal, which must be maintained regularly to prevent leaks and costly repairs. Many flat roof leaks are due to a lack of regular inspection and maintenance, so be sure that you have the time to check your roof regularly if you choose a flat roof for your property.
According to Improve Net's online roofing calculator, a flat roof is significantly cheaper than a pitched roof. A 900-square-foot flat roof in the San Francisco area, made of concrete tiles, costs approximately $6,108 to $7,635, whereas a moderately pitched roof with the same specifications ranges from $7,878 to $9,848. Of course, if you live in an area that receives a large amount of rainfall each year, any money you might save in flat roof installation costs might be compensated for in future repairs. Flat roofs' repair costs are more expensive than pitched roofs' are, and because they are less prone to moisture damage, a pitched roof may be more affordable in the long-term.
Consider whether the basic structure of a flat or pitched roof is right for your property. A pitched roof provides more structure and stability than a flat roof, as well as excellent drainage in areas that receive large amounts of rain. However, a flat roof is an inexpensive and practical option for those who live in areas that receive little rainfall. Flat roofs are also characteristic of modern design, so if you want to design a contemporary home, use a flat roof or a pitched roof with a very low slope.
