There are different types of flat roofs, depending on their destination and owners’ preferences.
According to their destination, they are divided into circulatable, non-circulatable and green. Depending on the execution option and the chosen insulation solutions (both hydro and thermo), there are classic, inverted and mixed roofs. Also, according to the thermal insulation material, flat roofs can be ventilated or unventilated.
When designing a flat roof, regardless its type, several details must be taken into account, which may be related to exterior factors (precipitation, sun exposure, the weight of the snow, wind load, temperature variations, roof top exploitation, etc.), or to interior factors (the building`s destination, the indoor level of humidity, etc.).
According to skilled commercial roofers Denver businesses recommend, the installation of a typical Denver commercial roof is performed according to its type and structure. All flat roofs have a diffusion layer, a vapor barrier, thermal insulation, a waterproofing layer, waterproofing protection and, in the case of circulated roofs, a support layer and a non-slip finish. It is a rather complex composition, but it is easy to install, and all these layers are necessary to avoid damage and to prevent the occurrence of water infiltrations.
