Commercial and retail environments house a diverse and fast-paced segment of business and customers who have to keep their companies up and running. That’s why our work with any number of commercial enterprises, shopping and retail centers comes down to responding quickly and efficiently so the “OPEN” sign stays lit.
Multi-family/condo environments create more than a “roof over your head;” it’s a soft place to land for everyone who calls your property “home.” That’s why so many residential property owners look to ARCH to ensure the safety and comfort their tenants deserve, and depend on.
ARCH understands industrial environments require specialized, often large and costly structures to support manufacturing, technical, and/or warehousing operations. Protecting your equipment, raw materials, products and most importantly, your work force demands customized and highly proficient roofing solutions.
ARCH builds roofs that bolster the functions and fundamentals of day-to-day operations, often factoring in engineering variables such as site geography and meteorological impact on sizeable buildings. Solutions to your roofing needs that keep you up and running.
People who have inspired and cared for us deserve nothing less than the most beautiful, comfortable and secure residential and health care communities possible. ARCH assures meticulous attention to detail, one of our own family values at these extra special places for the greatest generations. Now and to come.
We understand the important role that institutions of health, education and faith play within our communities. Schools, medical facilities and places of worship often hold historical and/or cultural significance. They are more than structures. They give structure to a community, and society depends on them.
To maintain their treasured integrity, ARCH recognizes the significance and sensitivity associated with protecting our institutions so that they may continue to inspire, and communities will prosper under the protection of an ARCH roof.
EPDM is an extremely durable synthetic rubber roofing membrane (Ethylene Propylene Diene Terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM is available in both black and white, and is sold in a broad variety of widths, ranging from 7.5 feet to fifty feet and in two thicknesses, 45 and 60 mils. EPDM can be installed either fully adhered, mechanically attached or ballasted, with the seams of the roofing system sealed with liquid adhesives or specially formulated tape.
BUR systems generally are composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. The number of plies in a cross section is the number of plies on a roof: The term “four plies” denotes a four ply roof membrane construction. Sometimes, a base sheet, used as the bottommost ply, is mechanically fastened. Built up roofs generally are considered to be fully adhered if applied directly to roof decks or insulation.
Modified Bitumen (MB) is asphalt that has had modifiers added to it to give it plastic or rubber-like properties. The most common types of modifiers being used are APP (Atactic Polypropylene) and SBS (Styrene Butadiene Styrene). Modified Bitumen roof systems consist of one, two, or three ply systems. The type of substrate will often determine the type of system being installed. Modified membranes can also be installed in conjunction with built-up roof materials (such as multiple plies of fiberglass felt) to form a “hybrid” roof system. Modifieds have proven performance on residential, commercial, and industrial applications.
The most common thermoplastic roof membranes are PVC and TPO.
PVC sheets are produced by calendaring, spread coating or extruding, and typically are reinforced with polyester or glass-fiber mats or scrim. PVC sheets contain plasticizers and stabilizers, as well as other additives to impart flexibility and achieve other desired physical properties. Some membranes are available with nonwoven fleece backing adhered to the underside of a sheet.
TPO membranes are produced by calendaring with lamination, extrusion with lamination, or extrusion-coating techniques. TPO sheets are a blend of polypropylene and ethylene propylene polymers and usually are reinforced with polyester. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties.
Steep Slope Applications
Steep-slope roof systems typically are composed of individual pieces or components installed in shingle fashion. Steep-slope roof assemblies typically consist of three primary parts:
Roof deck — The structural substrate, usually a wood-based material such as plywood or oriented strand board (OSB).
Underlayment — Provides temporary protection until a roof covering is installed and provides a secondary weatherproofing barrier. Sometimes underlayment is referred to as “felt” or “paper.”
Roof covering — The external water-shedding material, shake, shingles, slate, etc…
