SYSTEMS

RCI Roofing installs a broad range of roof systems. From low slope applications using single-ply membranes, thermoplastics, and modified bitumens, to steep slope applications such as asphalt shingles and metal roof panels, you can expect a quality roof system installed by experts in the roofing industry.

Rubber (EPDM)

Ballasted EPDM Roofing System

The Ballasted EPDM Roof System utilizes large EPDM sheets held in place by smooth river stone or pavers. This system is extremely versatile and available in several different variations. When stone ballast is used this system is the most economical. The smooth stones used in this system offer an aesthetically pleasing surface appearance. The weight of the basic Ballasted Roof system is 12-14 pounds per square foot. Most Factory Mutual and Underwriters Laboratory recommendations can be met with this system. All EPDM membranes can be used in this system which includes 45 mil and 60 mil non-reinforced and 45 mil and 60 mil reinforced, but the 45 mil non-reinforced is the most commonly used.

Fully Adhered EPDM Roofing System

With the Fully Adhered EPDM Roof System the EPDM sheets are fully adhered to the substrate with bonding adhesive. This system is extremely versatile and can be installed on steep slopes. This system also adapts itself very well to curved roof surfaces. This system is lightweight -- less than 2 pounds per square foot with most applications. This system is easily repaired. All Factory Mutual and Underwriters Laboratory recommendations can be met with this system. All EPDM membranes can be used in this system which includes 45 mil and 60 mil non-reinforced and 45 mil and 60 mil reinforced, but the 60 mil non-reinforced is the most commonly used. A white EPDM is also available that offers heat reflectivity.

Mechanically Fastened EPDM Roofing System

With the Mechanically Fastened EPDM Roofing System the EPDM sheets are fastened to the substrate with mechanical fasteners. This system is extremely versatile and can be installed on steep slopes. This system also adapts itself very well to curved roof surfaces. This system is lightweight -- less than 2 pounds per square foot with most applications. This system is easily repaired. All Factory Mutual and Underwriters Laboratory Ratings can be met when using reinforced membrane with this system. All EPDM membranes can be used in this system which includes 45 mil and 60 mil non-reinforced and 45 mil and 60 mil reinforced.

Metal Retrofit EPDM Roofing System

For installation over failing metal roofs. The EPDM roof sheets are fastened to the existing roof support structure with specially designed roof fasteners. This system is less costly than complete replacement with a new metal roof. Plus there is no down time for the building occupants while this roof is installed. Weighs less than 3 pounds per square foot. The pans of the metal roof are filled in with roof insulation, then the entire roof is overlaid with roof insulation. The addition of this roof insulation results in energy saving, helping the building owner pay the roof cost. All Factory Mutual and Underwriters Laboratory Ratings can be met with this system. 45 mil and 60 mil reinforced membranes are used in this system.

Thermoplastics (PVC, TPO)

Ballasted Heat Welded Thermoplastic Roofing System

The Ballasted Heat Welded Thermoplastic Roof System utilizes heat-welded sheets held in place by smooth river stone or pavers. This system is extremely versatile and available in several different variations. When stone ballast is used, this system is the most economical of the heat welded systems. The smooth stones used in this system offer an aesthetically pleasing surface appearance. The weight of the basic Ballasted Roof System is 12-14 pounds per square foot. Most Factory Mutual and Underwriters Laboratories recommendations can be met with this system. Either the 45 mil or 60 mil membranes can be used in this system. The heat welded systems that include PVC and TPO membranes are somewhat chemical resistant and stand up well to animal fats.

Fully Adhered Heat Welded Thermoplastic Roofing System

With the Fully Adhered Heat Welded Thermoplastic Roof System the heat welded sheets are fully adhered to the substrate with bonding adhesive. This system is extremely versatile and can be installed on very steep slopes. This system also adapts itself very well to curved roof surfaces. This system is very lightweight -- less than 2 pounds per square foot with most applications. This system is easily repaired. All Factory Mutual and Underwriters Laboratory Ratings can be met with this system by following their recommendations. Either the 45 mil or 60 mil membranes can be used in this system. The heat welded membrane is available in two colors: white which offers heat reflectivity and black. The heat welded systems that include PVC and TPO membranes are somewhat chemical resistant and stand up well to animal fats.

Mechanically Fastened Heat Welded Thermoplastic Roofing System

With the Mechanically Fastened Heat Welded Thermoplastic Roofing System the heat welded sheets are fastened to the substrate with a type of mechanical fasteners. This system is extremely versatile and can be installed on steep slopes. This system also adapts itself very well to curved roof surfaces. This system is very lightweight -- less than 2 pounds per square foot with most applications. This system is easily repaired. All Factory Mutual and Underwriters Laboratory Ratings can be met with this system by following their recommendations. All heat welded membranes can be used in this system which include 45 mil and 60 mil reinforced. The heat welded membrane is available in two colors: white which offers heat reflectivity and black. The heat welded systems that include PVC and TPO membranes are somewhat chemical resistant and stand up well to animal fats.

Standing Seam (Metal)

Modified Bitumen


There are two general types of polymer modified bitumen membrane systems, atactic
polypropylene (APP) and styrene butadiene styrene (SBS). These polymer modified
membranes differ in chemical characteristics. Both modified bitumen membrane types
are thick, heavyweight membranes, reinforced with either polyester, fiberglass or a
combination of both. Modified bitumen membranes commonly come with a factory applied
mineral, granule surface or an approved coating which is applied after the product is installed.
Modified bitumen roofing systems are similar to traditional built-up roofing because of
the multiple-ply application. The ply application is usually in two layers and can
vary from hot or cold, asphalt bitumen attachment or torch applied adhesion.

Asphalt Shingle

Organic shingles

Organic shingles are generally paper (felt) saturated with asphalt to make it waterproof, then a top coating of adhesive asphalt is applied and the ceramic granules are then embedded. A portion of the granules contain leachable copper or more often tin to prevent moss growth on the roof. Organic shingles contain around 40% more asphalt per square (100 sq. ft.) than fiberglass shingles which makes them weigh more and gives them excellent durability and blow-off resistance. Shingles are judged by weight per square.

Fiberglass shingles

Fiberglass shingles have a glass fiber reinforcing mat manufactured to the shape of the shingle. The mat is then coated with asphalt which contains mineral fillers. The glass fiber mat is not waterproof by itself and is a wet laid fiberglass mat bonded with urea-formaldehyde resin. It's used for reinforcement. The asphalt makes the fiberglass shingle waterproof. Fiberglass reinforcement was devised as the replacement for asbestos paper reinforcement of roofing shingles and typically ranges from 1.8 to 2.3 pounds/square. The older asbestos versions were actually more durable and were harder to tear, an important property when considering wind lift of shingles in heavy storms. Fiberglass is slowly replacing felt reinforcement in Canada and has replaced mostly all in the United States. Widespread hurricane damage in Florida during the 1990's prompted the industry to adhere to a 1700 gram tear value on finished asphalt shingles.

Shingles are ranked by waranteed life, ranging from 25 to 50 years. A newer design of asphalt shingle, called laminated, uses two distinct layers and is heavier, more expensive and more durable than traditional designs. Laminated shingles also give a more 3-D effect to a roof surface.
