ROOFING SYSTEMS 

Encore Roofing specializes at designing, incorporating, and delivering various roofing systems for your business.

TPO ROOF SYSTEMS

TPO roofs are seamless roofing systems that has quickly become a favorite of real estate developers, building owners, architects, general contractors and roofers.

TPO (thermoplastic olefin) became a popular roof membrane in the mid-1980s. TPO is a thermoplastic which means it can be welded together with hot air; therefore, not requiring seams to be taped or glued.

Combined with its lengthening track record, low comparative cost, and high reflectivity, TPO has quickly become a favorite of real estate developers, building owners, architects, general contractors, and roofers. Also, because of the versatility of the membrane and the multiple application choices available, TPO is a viable product on almost any project.

 

Whether you need to recover an existing built-up roof with fleece-back TPO in hot asphalt, fully adhere to TPO to achieve a higher wind uplift rating, or mechanically fasten TPO, this membrane should be considered as an option on your building. Because of these reasons, the use of TPO membrane continues to grow exponentially. TPO membranes are typically white but are available in other colors as well.

PVC ROOF SYSTEMS

PVC roofs are seamless and are resistant to certain chemicals, making them a durable roofing system.

PVC (polyvinyl chloride) roof systems offer many of the same benefits as TPO. PVC is also a thermoplastic which means it can be welded together with hot air; therefore, not requiring seams to be taped or glued. Although PVC is slightly higher in cost than TPO, it is lower in cost compared to asphalt roof systems, and just like TPO, PVC is a highly reflective roof membrane.

PVC roof systems offer the same versatility as TPO but PVC is more resistant to certain chemicals. The chemicals in oils, fats, and grease may cause a TPO membrane to prematurely deteriorate, while the PVC membrane may be more durable in those environments. If your building houses a restaurant, manufacturing plant, or some other business that may vent chemicals through the roof, PVC will provide a cost effective option that will perform under the circumstances presented at your property. PVC membranes are typically white but are available in other colors as well.

EPDM ROOF SYSTEMS

EPDM roofs have black thermoset membranes that are taped or glued down.

EPDM (ethylene propylene diene terpolymer), by nature, is a black thermoset membrane which can’t be remolded or welded. As a result, seams must be taped or glued as opposed to being welded together like TPO or PVC seams. For years EPDM has been losing market share to competing white single-ply thermoplastic membranes. That does not mean that EPDM does not have a place in the current roofing market.

There are many scenarios that EPDM may make sense. As an example, in a re-roof scenario on a building that has an existing ballasted EPDM membrane, structural calculations may require the ballast to remain on the building. In that case, replacing the existing EPDM with new EPDM membrane may provide the most durable roof system scenario.

Also, reflection from a white single-ply roof may create a problem in a multi-story building with lower roof areas. If a white membrane is used, light may reflect onto the side of the building and into the windows above creating unsightly aesthetics and an uncomfortable atmosphere for employees or owners

ASPHALT ROOF SYSTEMS

Asphalt roofs use multiple layers of asphalt to create a durable, waterproof membrane.

Asphalt based roof systems have a long track record of excellent performance. Unlike single-ply roof systems, an asphalt system uses multiple layers of asphalt, held together with felts or modified materials to create a thick, durable waterproofing membrane. These multiple layers make asphalt systems highly resistant to punctures.

 

Asphalt systems also have many surfacing options that can increase solar reflectivity and increase the life span of the roof. Surface options widely available today include coatings, gravel and granular surfaced cap sheets.

PRECISION SHEET METAL FABRICATION

A sheet metal roof is a roofing system made from metal pieces or tiles characterized by its high resistance, impermeability, and longevity. Zinc, copper, and steel alloys are commonly used.
