Membrane Installation

Flat Roof Membrane is installed directly over the rigid insulation. Membrane is the weatherproofing portion of the installation, and needs to be fully installed over the rigid insulation and any roof penetrations to make the building watertight. There are many different membrane products that can be used, and many different installation techniques. Every type of membrane product used in flat roofing is unique with its own strengths and weaknesses. For more information on the most commonly used membrane products, see our pages below on: Single Ply membrane roofs, like EPDM Membrane and TPO Membrane, can be installed a few different ways. The most commonly used membrane installation methods are: Asphalt based products, like modified bitumen and built up roofs (BUR) have their own installation methods. No matter what roof membrane product you use, the installation is comprised of two aspects: Field work and detail work. The field work, for the most part, is the easy portion where the membrane is installed over open, flat areas. The detail work is the harder portion, which includes areas like HVAC units, skylights, walls, roof hatches, and other penetrations and rooftop equipment in the roof system. Over 90% of flat roof leaks come from the detail portion of the flat roof work, so it is important to have an expert crew performing any membrane installation work. After the membrane […]

PVC “Vinyl” (Polyvinyl Chloride)

PVC Roofing Systems have been installed since the 1960’s and was one of the first single ply materials used in roofing. PVC Roofs come in thicknesses from .036 mil to .090 mil, can only be reinforced. PVC is typically white, tan or gray in color. A PVC membrane installation can be mechanically attached, fully adhered, Rhinobond or ballasted. Like TPO roof systems, PVC Membrane rolls and flashing membrane are heat welded together, creating the strongest bond available in a roofing system. A PVC Roof installation is heat welded together using computerized hot air equipment that reaches temperatures of around 800 degrees in the seams. For welding the seams on open membrane rolls, an automatic “robotic” welder is used that automatically sets the correct temperature, applies the perfect pressure, and sets the best speed to perfectly weld the two membrane sheets together. For smaller areas, like rooftop units and curbs, a hand-held heat welding gun is used, along with a rubber roller. These smaller detail areas rely heavily on the craftsmanship of the roofing mechanic to achieve the correct temperature, pressure and speed required for a perfect weld. Benefits of a PVC Roof PVC Roofing systems have solid strengths. Some Benefits of a PVC Roof are: Drawbacks of a PVC Roof In the roofing industry, PVC roof systems are being overtaken by TPO, because TPO holds […]

What You Need to Know About Flat Roof Designs

Flat roofs are among the most common and versatile types of roofs globally. While they are not the most glamorous and enchanting option, they have unique advantages. It’s important to note that flat roofs require special attention, care, and handling. Flat roofs differ from their contemporary counterparts in more than outward appearance. Costs, materials, and versatility benefits are distinct capabilities of flat roofs. So, if you’re a commercial building owner or a private real estate developer, you will most likely have to deal with flat roofs firsthand.Here’s what you need to know about flat roof designs: 1. Cost The cost of a flat roof system can vary dramatically. If you need to complete a full tear off, you also need to install code-compliant insulation, which can add dramatically to the cost. There are also big cost differences between the products available (TPO, EPDM, PVC) and how they are installed (Fastened, adhered, etc). Make sure you do your homework and know what you are getting before approving a proposal. 2. Maintenance On a flat roof system, maintenance is very important. Clogged roof drains and minor defects can create big problems down the road. It is very important to walk your roof at least once a year, clearing vegetation and checking for defects. An annual maintenance program can go a long way in making sure your roof […]

4 Reasons to Avoid Built-Up Roof Systems

A built-up roof system, also known as BURS, is a multi-tiered roofing system for flat roofs. Built-up roof systems provide roof protection against the elements with multiple layers of protective systems. A built-up roof system is also known as a tar and gravel roof. The number of layers in the system will depend on the owner’s preferences and usage of the building. Typically, it is installed in 3-5 layers. The more layers, or plies, the stronger the BUR system and the longer it will last. The first layer of a built-up roof system is typically a base felt paper. This prevents the BUR system from being adhered directly to the structural decking, making removal down the road difficult to impossible. Then, alternating layers of asphalt/tar are applied between additional layers of felt paper. Install felt sheet, mop on a layer of asphalt, repeat. The top layer of a built-up roof system usually consists of gravel. In a built-up roof system, gravel acts as UV protection, which will prevent the asphalt roof system from cracking and breaking apart over time. In some cases, coatings are applied instead of P-stone. This serves the same purpose, UV protection. However, in some cases, they also serve as a heat-reflective top layer that reflects sunlight and heat away from a building to help keep it cool and lower energy bills. […]

Adding or Renovating Your Property? Consider Upgrading Your Roof

The average roof will last 15 to 30 years in the United States. However, if you own a commercial building, you should not take anything for granted. It would be best to regularly inspect your roof and take proactive steps in renovating and upgrading your roof before problems develop. Here are three ideas on renovating or upgrading your roof to save money and improve the aesthetics of your commercial property. Related: EPDM Warranties Explained (And Why It’s So Popular) EPDM Over 50% of American buildings have mild to serious mold infiltration problems. Many people think leaky pipes cause expensive, façade damaging and health-endangering mold problems but sometimes, mold can infiltrate your building from the top. It would not take a lot of water infiltration via the roof for a mold problem to get out of control. Ethylene propylene diene monomer, more commonly known as EPDM, is a sheet material made of synthetic rubber. EPDM is used to line flat roofs and most commonly as the lining for artificial ponds because of its durability. EPDM lining is held in place with masonry pavers, ballast, glue, or fastening. It is a lightweight, relatively inexpensive material that offers enhanced insulation. As long as EPDM sheeting is installed expertly, leaks won’t be a commonplace occurrence. If your commercial property is located in a region with colder weather, then the […]
