Flat Rood Designs

Flat roofs are quite versatile. They come in amazing designs and these three are the most popular:

  1. Built-Up Roofing

This flat roofing design features at least three layers of ply sheets that are ballasted by smooth gravel. The gravel layer gives your roofing strength and durability. It also makes the roofing fire-resistant.

  1. Single Ply

This roofing design features a single-layered membrane that comes in different thicknesses. The most popular material here is EPDM. However, we have a few homeowners who go for synthetic rubber.

  1. Liquid Roofing

Often referred to as liquid applied or spray-on, this flat roofing design requires you to apply a spray solution to an existing roof to give it a flat orientation. In essence, you don’t replace your roof but you change the appearance.

Bottom-line

Flat roofs have everything you need in your roof replacement. Whether it’s a trendy design or durable material, there’s something that suits you in the flat roofing market. You just need to take the time to consider your options.
