Flat Roofing – Low Slope Roofs
Bowles Roofing have been installing, repairing and replacing flat roofs in Tallahassee and the surrounding area since 1984. Flat roofs have many applications for both residential and commercial uses. For residential applications, flat roofs are ideal when a homeowner wishes to add on a lanai or sunroom. The flat roof will blend much more effectively with the home and look aesthetically better versus unblended roof pitches. Many commercial buildings prefer flat roofing as they offer a better way to place HVAC units and other equipment without tying up high traffic areas at ground level. This also allows easy access for HVAC maintenance or repair. Regardless of whether you are installing a new flat roof, replacing or repairing, the professionals at Bowles Roofing have a flat roof solution to meet your needs.
What are the Advantages of Flat Roofs?
Flat roofs typically have a lower cost associated with construction. Because they use less space than a pitched roof there are less materials and less labor needed to install, repair and maintain them
In a world where energy costs often fluctuate, flat roofs can save you money. In most cases flat roofs are more energy efficient. New materials, and innovative insulation methods where a membrane system is applied over rigid insulation, will keep energy costs down. Another popular option is to apply reflective material to the roof. This is called a “cool” roof and will also lower energy costs
For a business or home that wants to install solar panels, a flat roof makes an excellent base for their installation
In both residential and commercial usage, a popular trend has been to use the flat roof for rooftop gardens and as an area to lounge or barbecue

Types of Flat Roofing Material
Choosing an appropriate flat roofing material is a two-part process. On one hand, you want a substance that has nice aesthetics while fitting within your budget. You also want to know the product will last:
- TPO Single-Ply Membrane: 15 – 30 years’ expectancy. Thermoplastic Polyolefin (TPO) is a single-ply reflective roofing membrane made from polypropylene and ethylene-propylene rubber polymerized together. TPO is installed in a fully adhered or mechanically attached system and is arguably the most popular of all flat roofing materials. TPO membranes are composed of a single layer of thermoplastic material which is especially strong and durable. The seams are heat-welded to form a watertight bond. The welded seams are stronger than the material itself. TPO membranes, especially white-colored ones, are very energy efficient, coming with a 5-Star Energy Rating from the Department of Energy. TPO roofs have been vastly growing in popularity mainly due to their energy-efficiency and availability. TPO is said to offer the best of both EPDM and PVC in one package. The material is closer to a rubber roof in cost, but also features welded seems for durability like PVC membranes.
- PVC: 7- 20 years’ expectancy. PVC stands for polyvinyl chloride and is another single ply roofing membrane that chemically bonds rubber, ethylene, and propylene as well as numerous filler materials. Like most materials used on flat roofing, PVC comes in a membrane form. This membrane is rolled out onto the roof and adhered to the deck either with adhesives or nails. Like its counterpart TPO, PVC is usually heat welded at the seams. This is important because seams are the weakest part of any flat roof and the heat welding seals the areas and keeps them watertight.
- Modified Bitumen: 10- 20 years’ expectancy and modified bitumen features an advantage since it is a multi-ply roofing material. A base layer is mechanically attached to the roof deck with plates or bars. Then a strong, durable Granular top surface is applied to provide aesthetic and energy efficient properties.
- Built Up Roofing (BUR): 15- 20 years’ expectancy is better known by their ‘street name’ of tar & gravel roofs, BUR is just that. Built up roofing can include up to four plies or more consisting of alternating layers of bitumen (asphalt, coal tar, or other adhesive) with a topping aggregate layer of gravel or other materials. Built up roofs have been in use for over 100 years with their biggest advantage being the ability to withstand traffic and collisions with elements.
- Coating Roof Systems: 15- 20 years’ expectancy- Silicone or elastomeric coating is an example of a coated roof. The material can be applied right over some existing roofs. The biggest advantage of a coated roof is that it has no seems and its wide array of uses.
- EPDM: 10- 15 years’ expectancy and is commonly known as a rubber roof. One of the biggest advantages of EPDM over a PVC roof membrane is a much lower price. The seams of EPDM are not as strong as the PVC, heat-welded joints either. EPDM also tends to absorb heat, which can drive up utility bills for the property owner. It is more widely popular in the North as the membrane itself retains heat.
Bowles Roofing did a terrific job. They were extremely patient working with us on our decisions and when it was time to go (it's summer and always raining or so it seems) they were on the job and quick. The best part to me was...There were no surprises in the final bill. If you're in need of a new roof, I highly recommend Bowles Roofing.
