We install and service low and steep-slope roofing, sheetmetal, and various types of wall panels (aluminum composite , insulated metal, and single skin sheet metal) – for commercial, manufacturing, industrial, government/public work, as well as religious, educational, and hospital facilities.
Some of the various types of roof systems we install and service include single ply, standing seam metal panels, coatings including rooftop paver systems, modified bitumen, and built-up. Pickens Contracting is also an authorized applicator for all major roof system manufacturers for low and steep slope roof applications, and many wall panel system manufacturers.
There are various single ply roof systems available including TPO, PVC, KEE, and EPDM being among the most common.
Metal roofing and siding are preferred options due to their durability, versatility, customizability, and low maintenance. Our sheet metal fabrication shop is well equipped and highly capable of manufacturing most metal roof and wall panels and components.
This type of roof system is typically made up of two to three layers of modified bitumen rolls with a ‘cap sheet’ installed as a top layer. The cap sheet traditionally has granules adhered to it that are available in a variety of colors and varying thermal reflectivity properties. These can be installed with adhesives, or torched (which heats the asphalt and allows it to soften and adhere to layers below). Modified bitumen roofing systems are made up of asphalt-based roof components that include modifiers that are added to roofing asphalt to replace plasticizers removed during distillation. Bitumen is reinforced with polyester fiber or fiberglass matting to increase durability and strength. This system is typically utilized on low slope roofing applications for commercial properties
Built-up roofing, or BUR, is a roof system that has been around for over 100 years. Although the materials and installation have evolved over that time, the methodology and concept is very much the same as it was decades ago. It is a system comprised of three basic parts – bitumen material (hot or cold asphalt), ply sheets (made from organic felts, or fiberglass felts), and one or more surfacing materials. This type of roofing can be installed with hot bitumen or cold bitumen.
Each ply sheet layer is laid over hot or cold bitumen to bond it to the roof system. Surfacing materials form the top layer and generally consist of small gravel.
These types of roof systems provide excellent waterproofing and UV-protection. They are also highly fire-resistant due to the aggregate covering.
Slate is a rock, quarried and cut for use in roofing applications. It is a shale-type sedimentary rock that is by its nature incredibly durable and maintenance free. When used in roofing applications, the lifespan of a slate roof can be 75 years or many more. Slate roofing is available in a variety of sizes, colors, and thicknesses.
Tile roofing is also a durable and trouble-free roofing product. Typically made from either concrete or clay components and formed into a variety of shapes, tile roofs offer an aesthetically pleasing roof system.
These roofing materials both have benefits including the ability to increase resale value of a property and enhancing the architectural style of a building. They also both are fire and mold resistant and resist damage from ice and snow. Additionally, they are both hail and high wind resistant.
TPO (Thermoplastic Polyolefin):
TPO is widely desirable for use as a roof system for its cost, durability, energy efficiency, and ability to be recycled. It is designed to promote longevity of the physical structure and reflect UV rays for reducing heating inside the building and on the roof. TPO is also resistant to such damaging materials as debris, dirt, bacteria and algae, which makes it even more durable. It is comprised of strong seams that are welded together. Typical TPO membranes incorporates both a cap and core membrane with a polyester reinforcing scrim encapsulated between these layers. The cap is up to 75 percent TPO polymer with 25-35 percent fire retardants, as well as small amounts of pigment and UV stabilizers. The core membrane is similarly composed but includes up to 15 percent recycled TPO and it does not need UV protection.
PVC (Polyvinyl Chloride):
Excellent puncture and fire resistance are some of the main benefits of PVC roofing. Additionally, a PVC roof is highly resistant to oxidation reactions. This makes it exceptionally safer than other types of roofs. PVC is composed of ethylene and chlorine. In its compounding process, vinyl resin is blended with biocides, color pigments, heat stabilizers, ultraviolet light inhibitors and plasticizers. A PVC roof consists of a single-ply membrane composed of two layers of PVC material covering a reinforcement scrim. The top layer is UV-resistant and flexible and can take on color through pigmentation. The bottom ply is often grey or black PVC and contains more plasticizers for flexibility and weldability. The reinforcements for PVC are typically polyester or fiberglass (when not mechanically fastened) and are added to provide increased strength, longevity and dimensional stability, thus improving performance and enabling the material to be a long-term, proven roofing solution with multiple installation options.
KEE (Ketone Ethylene Ester):
KEE based PVC roof membranes offer superior chemical resistance, flexibility, and durability. It is indisputably known to be the highest-performing thermoplastic roof membrane on the market. KEE is a high-molecular-weight polymer with elastomeric properties and favorable melting properties for thermoplastic processing. It is manufactured solely by DuPont™, under the brand name Elavloy®. KEE provides additional desirable characteristics in roofing membranes, including easy heat welding due to melting properties, weather resistance, resistance to microbial growth, and retention of energy efficiency over time.
EPDM (Cured Ethylene Propylene Diene Monomer):
EPDM is traditionally black in color and has been available since the mid 1960’s for use as a roofing system. The material can be extruded or calendered into sheet form and can be reinforced with a polyester scrim for higher tear strength performance. EPDM performs well because it is highly UV stable due to the carbon black component in its make-up and has relatively high installation efficiency and consistency. Well-constructed, thoughtfully installed, and consistently maintained EPDM roof systems are very resilient. EPDM systems are known for their longevity, lasting 30 years or more. They have been proven to withstand extreme weather events. EPDM is resistant to the ozone, as well as scuffing, abrasion and impacts from hail. The roofs are durable, even against thermal shock, and resistant to heat and fire.
Standing seam roof panels are roll formed and available in various widths and panel profiles. They are generally installed with concealed clips atop a roof deck and insulation. They offer a strong, safe, and maintenance free roof system. This is due to the nature of sheet metal to guard against hail and wind damage and provide a long-lasting finished color.
Single skin metal panels, available with either concealed or exposed fasteners are highly customizable and available in a wide range of widths and profiles. These are commonly used in soffit and siding applications.
Insulated metal panels (IMPs) are exterior wall and roof panels with steel skins and an insulating foam core. Insulated metal panels are known for their superior thermal properties, design flexibility and fast installation time – in addition to their great looks. Insulated metal panels are weather-tight and provide a strong thermal and moisture barrier. These panels engage with joints that provide protection from wind, rain and moisture and allow aesthetic integration of a multitude of profile types. These are available in a wide array of textures and finishes to match any project.
Our metal shop is capable of fabrication of a wide variety of specialty fabricated sheetmetal items commonly used in roofing applications, and just about anything our customers could need from native metals such as zinc, copper, aluminum and brass.
