A flat roof system is a common architectural design that differs from pitched or sloped roofs in that it appears level, though it typically has a slight slope for water drainage. The basics of a flat roof system are addressed in this YouTube video and include:
- Roofing Material: Flat roofs are covered with a variety of materials, the most common being built-up roofing, single-ply membranes, or metal. The choice of material depends on many factors.
Video Source - Decking: The roof structure consists of a sturdy deck, usually made of wood, concrete, or metal, which provides a base for the roofing material. The deck is designed to support the weight of the roof system and equipment such as AC units.
- Insulation: Flat roofs require insulation to regulate temperature and reduce energy costs. This insulation is typically installed above the deck or within the roofing system.
- Drainage: Proper drainage is crucial to prevent water from pooling on the roof. Most flat roofs have a slight slope, known as the “pitch,” to direct water toward drains or scuppers that channel it off the roof and into downspouts.
- Flashing: Flashing materials, such as metal or roofing membranes, are used to seal roof penetrations, seams, and edges, preventing leaks and water infiltration.
Regular maintenance is vital to ensure the integrity of the flat roof system. This includes inspections, cleaning, and repairs to address any wear and tear or damage to the roofing material. Check out the video today and learn more about flat roof basics and what to do to keep on in tip-top shape!
