• Easy Installation: The straightforward design often allows for quicker installation processes.

Common Uses for Flat Roofs

Flat roofs are commonly found in commercial buildings like warehouses and retail spaces but are also gaining traction in residential constructions. Their versatile nature makes them suitable for various applications.
