If you’re thinking about installing a roof covering on the new house, you need to think about your choices and discuss all of them with an event roofer. Meanwhile, let us discuss the three primary kinds of flat roof: built-up roof, modified bitumen roof, and rubber membrane roof.
Fundamental essentials most everyday sort of flat roofs and can include the standard hot-tar-and-gravel roof. Featuring a minimum of 3 layers of waterproof material with tar and gravel in between each layer, these kinds of roofs are relatively affordable while taking advantage of improved technology which makes them stronger. One of the primary advantages of built-up roofs is they offer excellent protection against fire as gravel is a superb fire-proof. They’re also the least expensive flat roof system and therefore are a beautiful choice for those who have home windows that disregard the roof. However, built-up roofs are usually very heavy and joists may need extra support. Furthermore, system installation and repair isn’t suggested for that DIY-inclined as possible difficult to get the origin of leaks which product is untidy to set up.
Modified Bitumen Systems

These are typically single-ply folded roofing systems that act like ice-and-water shields, however they have a mineral-based put on surface. There’s two subtypes of modified bitumen roof: torch-lower systems and peel-and-stick systems. Torch-lower systems should be heated to be able to activate the adhesive whereas peel-and-stick systems don’t need to be heated which makes them safe and simple to set up.
Peel-and-stick roofs ought to always be installed with a professional roofer, but they’re simpler to manager for any DIY homeowner. However, torch-lower application is a lot more challenging and poses a substantial fire risk so must only be used by professionals. Furthermore, torch-lower systems shouldn’t be placed on occupied structures. Another advantage of those roofs is the fact that their light-coloured surface helps you to reflect heat and lower energy bills. These kinds of roof systems are moderately priced.
