Respecting and properly designing a commercial rooftop has beneficial effects on the lifespan of the building and on reducing energy losses. This project must be carried out by commercial roofing Connecticut specialists, who will take into account the concrete conditions of the building. The main part of the construction of a flat roof consists in the optimal design that should take into account all the components of the roof.

The simple construction of a flat roof involve several components such as: a floor, a perimeter attic, slopes for water drainage, water drainage holes, thermal insulation and waterproofing as protective layers.

Ensuring easy access to a non-circulating flat roof is not necessarily a priority, as you can use a hatch or an external metal staircase. The costs are lower than for circulating roofs, as they do not include specific finishes or staircases. A non-circulating roof can still be walked on for maintenance, periodic checks ups or accessing technical appliances stored on the roof (conditioning units, solar panels etc.).

In order for a non-circulating roof to become circulable, it must be covered with a resistant membrane, the elevation of the perimeter parapet must have minimum 1m in height, and the roof must also be easily accessible.

Both types of flat roofs (with circulating or non-circulating surface) have the same system of waterproofing and thermal insulation layers.
