While flat roofs tend to be common on large buildings, such as condominiums, and outbuildings, they can be found on single-family homes, too. Flat roofs offer many advantages, but there are some considerations to know if you’re thinking of purchasing a home with a flat roof. Learn about the pros and cons of a flat roof for your house.
Advantages of a Flat Roof
Flat roofs cost less than pitched roofs, in part because the material used to cover these roofs is cheaper. A flat roof can also be used for outdoor living space, such as a garden, patio, or roof deck.
Solar panels are becoming more popular these days among homeowners who value energy efficiency. Solar panels can be easier to install on flat roofs, which can bring down the cost of this home repair.
Then there are the benefits to your home’s interior of a flat roof. Interior rooms have more overhead space, because the ceiling doesn’t need to slope at the eaves. With a pitched roof, air can congregate in the ceiling, leading to a loss of energy efficiency. The shape of flat roofs can lead to a higher energy efficiency, because there’s not this extra space where air can gather.
Disadvantages of a Flat Roof
Flat roofs tend to last ten years on average, which is far less than a pitched asphalt roof.
Flat roofs don’t drain well; their shape doesn’t allow it. Standing water can cause water damage if it puddles and seeps under the roofing material. Come winter, snow and ice can accumulate on the roof. A bad winter may mean a heavy snow load that compromises the integrity of the roof. Thus, flat roofs may work better in warmer climates where snowfall is light than in areas that experience significant winter weather.
Green roofs have become popular on both pitched and flat roofs. With any green roof, proper care and installation is critical; if the roof is not constructed properly, plant roots can grow through the roof! Water can seep through the roof as well, causing significant damage.
