Commercial buildings have all kinds of roofs but, when we speak of it, we are generally concerned with large commercial flat roofs. The major types of commercial roofing in South Florida are:

  1. Hot asphalt & modified Bitumen

  2. Single Ply – TPO and PVC

  3. Industrial roofs are mostly metal. More HERE

Hot Asphalt & Modified Bitumen Roofing Commercial Roofing

Both of these systems use hot asphalt to create the roofing membrane. Roofer ‘s refer to this type of roofing as “Hot”. Low sloped asphalt is heated in a kettle to 550 degrees and pumped in a pipe to a “mop cart” on the roof. Crew members apply the asphalt (“hot”) with a mop and the roofing plies are rolled out into the hot asphalt. These systems have multiple layers of redundant protection and are a great selection for roofs with high traffic. Modified bitumen roofing is different than traditional hot asphalt because rubber is melted in with the asphalt. The practice was originally conceived in Europe as a way to remove old car tires from land fills. It turns out however, that the practice not only recycles the rubber but that the addition of the rubber gives the final product more Ultraviolet Ray protection, greater elasticity and a longer life expectancy. The recycled rubber actually improves the product. Asphalt based roofing systems can qualify for up to 25 year warranty. Generally speaking the more layers of rolled roofing, the longer the warranty

Torch applied applied roofing versus hot asphalt Roofing

Modified bitumen roofing came on really strong in the 90’s. It’s a lot easier for a roofer to carry a bottle of propane on a roof and simply use a torch to apply the rolled roofing materials than it is to set up an asphalt kettle and pump 550 degree asphalt up there. It might be convenient, but we don’t think it’s so great. The lines parallel in the picture above are lines of uneven heat application by the torch. In those areas the bond may not be adequate and a leak can result. Also, with a torch applied system you  only get the asphalt on the roll. As opposed to the additional asphalt that the hot mop provides. We highly recommend hot mop applications for asphalt built-up roofing.

Single-ply roofs

Single-ply systems where originally referred to as Co-polymer Alloy (CPA) or Thermoplastics. The term Thermoplastic refers to the heat welding used to weld the sheets together.These systems use plastic to cover a polyester scrim. There have been many formulations developed over the years. PVC was a popular formulation for many years. Today the modifier of choice is termed TPO (Thermoplastic Polyolifin). Single-ply TPO commercial roofing is by far the most popular commercial flat roofing system today. The first advantage is that they are white and reflect heat. In fact, for some installations FPL will give a rebate for the reflective quality. The big factor for the single-ply roofing’s popularity is its lower cost. The material cost for these roofs is simply less than that for conventional roofing. There is one downside however. As the name “single-ply” implies, there is just one layer. Conventional roofs have multiple layers that offer redundant protection. If for any reason a hole develops in a single ply system, you get a leak. If you get a hole in an area with ponding water, you have a new drain. If your commercial roof is a high traffic roof then you probably want to consider a thicker 60 mill membrane for a little added protection

Single-ply systems are rolled in place loose laid with a six inch lap to adjacent rolls. Screws and plates are used in the laps to anchor down the roof. The laps are heat welded together using hot air guns. Quality commercial roofing contractors like us use robotic heat welders to ensure perfect welding.

There is one advantage to single-ply roofing systems and that is their ability withstand ponding water. Single-ply roofing was developed as an offshoot for tank and pond liners. While asphalt roofing is broken down through oxidation by water, these single-ply system can have water on them 24/7 without damage.

Polyurethane Foam Roofing

Polyurethane foam roofing might be considered a third category but it represents such a small percentage of the commercial market share it cannot really be considered a contender (Not to mention its poor performance record).

Does your flat roof need to be sloped?

Believe it or not, many years ago, it was thought that having water “pond” on your roof offered insulating benefits. There were many roofs designed to pond water. Today we know better and in fact, under the new Florida Building Code, new roofs are required to be designed and shed water. This does not mean that your existing flat roof has to be re-redesigned to shed water. So lets clarify that! If you have an existing flat roof without a pitch, and you are re-roofing it, you do not have to install a pitch for the new roof. [Update! some building departments are now requiring retrofit slope to drain on roofs. One such City is Delray Beach]. The new Florida Building Code says that flat roofs must be sloped on all newly constructed buildings, not as a retrofit. So, if you have a commercial contractor telling you that you have to provide a pitch for a new roof, call us fast!

Is it better to have a sloped roof? You Bet!. But you don’t have to pay for it is your don’t want to.

Roofing Warranties

Roofing warranties are really the dirty little secrete of the roofing industry. This is particularly true with commercial roofing systems. Most roofing warranties are written highly in favor of the manufacturer and contractor. Those of us in the industry affectionately refer to these warranties as “taillight” warranties. When you can't see the roofers truck taillights anymore, your warranty has expired. At Preventive Maintenance Support Services Company we really do stand behind our work. We are not afraid to return and  fix anything that’s needed. We can also step it up a notch and provide you with a system warranty by the manufacturer. The advantage being the manufacturers have bigger pockets and in most cases have set up funds for warranty claims.

Roof Maintenance 

We cannot overemphasize how important it is to conduct regular roof maintenance. We recommend annual inspections to check for any hidden damages and to reinforce the flashing around your skylight, rain gutter, vents, and other fixtures. Our roofing technicians will also remove any debris to prevent water from collecting on the roof and damaging it. We will also identify and repair small. Good roof maintenance will improve the condition of your roof and roofs in good condition last longer.Its that simple

Metal roofs are common among commercial properties. Standing seam metal roofs add a great touch to your architecture and do not wear out as quickly as other materials. These roofs may come with a fifty-year warranty. Corrugated metal roofs are less costly than standing seam, but are just as durable; they are usually installed on sheds, barns, and other small buildings. Our team specializes in metal roof repair, so if you choose this material you can rely on us to service any problems. 

Asphalt shingles are a common option and generally come with a thirty-year warranty. These shingles have gone through several improvements over the years and are available in a range of colors.
