Bauhu home designs with flat roofs use EPDM (ethylene propylene diene monomer) manufactured by Firestone, which is a synthetic rubber roofing membrane commonly used in flat or low-sloped roofing systems. EPDM roofs are durable, flexible, and resistant to a wide range of weather conditions, making them a popular choice for commercial and residential buildings.

There are several different types of EPDM roofing systems, including fully adhered, mechanically attached, and ballasted systems.

In a fully adhered EPDM roofing system used for Bauhu Homes, the EPDM membrane is adhered directly to the roof deck using a special adhesive. This type of system is effective in preventing water infiltration, but it can be more labor-intensive to install and may require the use of heavy equipment.
