If you live in a period home, you might be fairly alien to the concept of a flat roof. Roofs of this type were, after all, uncommon on Victorian homes. These days, flat roofs are much more common, but you should still be aware of the many implications of a flat roof before choosing one for your own residence.
How financially desirable is a flat roof?
If you would prefer to keep your new roofing fairly restrained financially, it could delight you that flat roofs tend to require a lesser upfront cost than pitched alternatives, as the Royal Institution of Chartered Surveyors explains. Furthermore, you are unlikely to have to wait quite as long for construction to be completed, as flat roofs have a simpler structure than traditional pitched roofs.
However, one major drawback of flat roofs is that they can necessitate more maintenance. Clearly, if your financial situation is consistently tight, you wouldn’t be too pleased if you have to regularly shell out for repairs to the structure. Those repairs could become needed especially often should the roof surface be disturbed or people often walk over that surface.
Water way to treat a roof
There is a good reason why, historically, roofs have often been pitched rather than flat. Rain is something from which your home can obviously often need to shield its occupants. When rain falls on a sloped roof, it can readily slide off due to the roof’s overlapping pieces that resemble fish scales.
However, flat roofs fail to shed water as easily, The Spruce cautions. This can be attributed to the roofs’ extremely low slopes – which, in roofs that have been properly constructed, can be between ¼” and ½” per foot. Therefore, flat roofs sometimes need to handle standing water.
If you do select a flat roof, you ought to check that its falls remain adequate for preventing standing water – otherwise called ponding – becoming a big issue. Flat roofs should also be sealed in a way that prevents water ingress.
How different materials can affect flat roofs’ effectiveness
It’s still crucial not to make or accept too many broad, sweeping statements about how effective flat roofs can be. Ultimately, it’s a factor that can be influenced by what the roofs are actually made of.
The various types of flat roofing include EPDM roofing, the most oft-used kind of membrane or single-ply roofing. EPDM comprises recycled rubber materials and, for that reason, is kind to the environment. This roofing is also waterproof and can stay intact for 30 to 50 years before a new installation is needed. The roofing can withstand water, wind and fire as well.
One alternative, however, is modified bitumen roofing. Invented in the early 1960s, it uses polymer reinforced roof wear layers or cap sheets to deliver notable durability. Safe installation of this roofing can, nonetheless, require special techniques. Fortunately, our roofers from Hartlepool can safely install roofing of various materials on residences in any city, town or county of the North East.
