The choice of the different types of flat roof covering is significant. Thus, there is a need to learn more about the different types of flat roofs.
Types of Flat roof coverings
The abbreviation GRP stands for Glass Reinforced Polyester. GRP composes of chopped strand mat glass fibers and polyester resin. Besides, they combine to form a laminated roof design.
Weight: GRP is the best option for green and lightweight roofs. Other materials may be heavy, but fiberglass offers protection and are more complex roof shapes.
Durable: They are powerful and last longer. Ensure you hire a professional to assist in installation. GRP lasts for almost up years.
No linkage: The flat roofs have no joints left on the roof surface. Besides, they leave a smooth, shiny finishing for the roofing system.
Colour choice: GRP comes with a diversified range of colors., thus a good choice for homeowners.
The type of roofing system uses rubber which is a bit traditional. Bitumen and asphalt were other choices, where one uses rubber for the flat roof covering.
Cost-effective: Flat roofs replacement and repairs are usually needed more often. Once you use EPDM, you will save maintenance costs for a more extended period.
Easy to install: Anyone can install since it is not involving
Durability: Due to them being durable and robust, there is no need to replace them more often.
Strong: EPDM membrane has a versatile material that is used on garage and apex shed roofs.
3. Torch on felt
It is also referred to as torch-down roofing or flat roof covering solution. It comes with modified bitumen of three layers which is melt welded on the top. Torch on felt bitumen has a system technology that includes App modified and SBS roofing systems.
Watertight seal: The roofing is remarkably resilient to the one installed. Besides, it seals up imperfections and more minor cracks.
Versatile design: They are relatively flexible when rolling up the sheets, and you can easily cut them into size and shape.

The felt roofing is considered to have a shorter life span. The installation process can be a fire hazard, and once you repair, the roof will not please the eye.
Difference between Warm flat roof construction vs. Cold flat construction
Warm flat construction
The insulating layer is placed above the timber rafters. Besides, it results in the loft and roof area being at the same temperature as the interior of the building. Warm flat roofs designs make the whole structure of the building relatively warm.
Cold flat roof construction
The construction involves placing an insulation layer between the level with the ceiling joist. Thus, leaving the timber and roof cold. Furthermore, it requires a breathable membrane between roof structure and insulation.
Flat roofs can be of different types. In addition, other types may include; Thermoplastic PV membranes which are single-layer materials. Others may consist of spray polyurethane foam roofs, which all fall into flat roof coverings.
