Naples Roofing has nearly 40 years experience installing a variety of different systems that work well for commercial applications. Analyzing life cycle cost, roof traffic, warehouse contents, and factors such as long-term ownership versus short-term lease are all factored into determining which type of commercial roofing system these large projects require. A commercial roof can be a big source of energy inefficiency. Commercial roofing systems are notorious for soaking up solar heat. While a facility’s ability to absorb heat might be advantageous for some facilities in the winter, it often means wasted money overall.
Modified Bitumen (Mod Bit) roofing is the next generation of the tried-and-true built-up roof. Typically comprised of 2-3 plies of asphaltic felts, they can be torch-applied or installed with cold adhesive. Mod bit roofs typically have a granule-surface cap sheet and are available in a variety of colors. Some manufacturers have modified cap sheets with enough solar reflectivity to meet LEED requirements. Modified Bitumen was first developed and utilized in Europe in the 1960s. This membrane is manufactured in uniform sheets comprised primarily of polymer-modified bitumen reinforced with one or more plies of fabric, or ply sheets. The fabrication can include polyester, glass, or a combination of the two. When applied in roofing, the finished version may be comprised of several sheets of modified bitumen and asphalt to create a uniform matrix. When used in conjunction with a thermoplastic polymer, APP (Atactic Polypropylene), a uniform matrix is created within the modified bitumen sheets. This matrix increases the bitumen's resistance to ultraviolet (UV) light, increases its flexibility in extreme temperatures, and increases it resistance to water penetration. This added resilience and enhanced durability under extreme conditions makes modified bitumen a prime choice when there may be movement or deflection of the underlying deck of a roof. Modified Bitumen roofing systems create watertight barriers that perform for many years at a time due to the multiple layers. When built-up, these layers of bitumen exhibit exceptional resistance to conductivity of heat between the exterior and interior of the building. This generates noticeable reduction in heating and cooling costs. The thermoplastic polymers used in the modified bitumen make it more fire resistant as well. The technology employed in creating this roofing system makes it affordable and easy to generate as well.
EPDM rubber (ethylene propylene diene monomer (M-class) rubber), a type of synthetic rubber, is an elastomer which is characterized by a wide range of applications. The E refers to ethylene, P to propylene, D to diene and M refers to its classification in ASTM standard D-1418. The M class includes rubbers having a saturated chain of the polymethylene type. Dienes currently used in the manufacture of EPDM rubbers are dicyclopentadiene (DCPD), ethylidene norbornene (ENB), and vinyl norbornene (VNB). EPDM rubber is closely related to ethylene propylene rubber (ethylene propylene rubber is a copolymer of ethylene and propylene whereas EPDM rubber is a terpolymer of ethylene, propylene and a diene-component). Ethylene Propylene Diene Monomer (EPDM) is a rubbery singly-ply roof membrane traditionally black in color, although white EPDM is available. It is resistant to temperature extremes, and exhibits the least brittleness of the common single-ply membranes in freezing temperatures.
Built-up roofing (BUR) systems typically consist of 3-4 plies of fiberglass felts applied over insulation or other materials embedded in hot steep asphalt or cold asphalt adhesive in a multi-ply configuration. Gravel applied over a BUR system serves two purposes; first to protect the membrane from ultraviolet rays and second, to act as a ballast to hold the roof in place. BUR systems are typically one of the least expensive roofing options due to their durability and speed of application, especially in large, new construction scenarios. On the downside, hot asphalt produces a strong aromatic odor during application, which may disturb building occupants &/or neighbors.
ThermoPlastic Olefin (TPO) is highly resistant to UV rays and is becoming increasing common in roofing. It may be applied on low-slope or steep-slope roofs, and can even have strips applied which give it the appearance of a standing-seam metal roof at a lower cost than metal. TPO is available in a wide variety of colors, including highly-reflective light colors eligible for LEED points and EnergyStar credits. TPO is the brand name for thermo-plastic polyolefin or Thermal Polymer Olefin. TPO is comprised of materials combined in a thermal reactor at a molecular level; once combined, the molecules fuse together and cannot be separated, as opposed to other materials that are ground up and melted together. TPO is one of the lightest, most recyclable materials on the market. With a built-in, Ultra Violet protection, it is also one of the most weather-resistant materials on the market. Because it is a polymer, it is a great insulator that also protects buildings from the elements, as it does not conduct sound, electricity, or heat; TPO keeps buildings cooler in the summer. Due to the nature of this material, it stands up to even the most extreme weather conditions without expanding or contracting, which is why the automotive industry uses it in fenders, bumpers, doors, and other body moldings. TPO is also very impact resistant and resilient, making it a prime choice when considering roofing systems that will stand up to extreme conditions and harsh storms.
Polyvinyl Chloride (PVC) roof membrane consists of two layers of PVC with a reinforcing scrim sandwiched in the middle. Like TPO, PVC roofs are installed with heat-welded seams which make them exceptionally watertight., however PVC membrane has the ability to withstand harsh chemicals. PVC stands for polyvinyl chloride, meaning it is comprised of carbon, hydrogen, and chlorine (from salt) on a molecular level. When heated sufficiently, thermoplastics temporarily shift from a solid to a semi-solid state enabling the sheets or panels that are overlapped to fuse together as a solid upon cooling. This process yields one, continuous membrane rather than several compressed particles. This process, referred to as heat-welded seam technology, is one of the most beneficial features of PVC. First appearing on roofs in Europe in the 1960s, PVC has the longest track record in roofing membranes of all thermoplastics. Since it has been widely tested and perfected, there are many options with this type of roofing membrane.
Architectural Sheet Metal is a specialized type of metal roofing, typically involving steep slopes. These roofs feature custom fabricated sheet metal flashing and trim and generally are used for historic, retrofit projects. We work with various gauge metals and various types of metals, ranging from pre-finished galvanized steel and aluminum to copper, stainless steel, lead and coated copper. Architectural sheet metal roofs are typically used on homes and smaller buildings, since most commercial buildings have gently-sloped or flat roofs that are better suited to other types of roofing systems.
