Types of Commercial Roofing

TPO PVC EPDM Modified Bitumen Membrane: SBS Modified Bitumen Membrane: APP

TPO

TPO (Thermoplastic Polyolefin)

Thermoplastic polyolefin (TPO) is leading the trend in white, reflective, energy-efficient, single-ply roofing systems—and is the fastest-growing commercial roofing membrane on the market today. TPO has garnered broad industry acceptance for its many installation and performance advantages, including its ability to be heat-welded, creating a monolithic roof while providing strength and durability. Its white reflective membrane also meets the criteria of LEED®, ENERGY STAR® and other environmental programs. TPO & PVC are one of the top flat roof options due to its ease of installation and its resistance to water ponding. The seams in the TPO/PVC system are “Hot Air” welded using a computerized robot in most case creating less maintenance and/or repair visits. TPO sheets contain colorant, flame retardants, UV absorbers and other proprietary substances to achieve desired physical properties.

Best for: ENERGY EFFICIENCY • HEAT REFLECTION • PERFORMANCE

PVC

PVC (Polyvinyl Chloride)

PVC is a flexible, thermoplastic membrane manufactured using ultraviolet-resistant polyvinyl chloride. The membranes are produced in numerous colors, though gray and white are the most common.TPO & PVC are one of the top flat roof options due to its ease of installation and its resistance to water ponding. The seams in the TPO/PVC system are “Hot Air” welded using a computerized robot in most case creating less maintenance and/or repair visits.

Best for: DURABILITY • HEAT REFLECTION • WITHSTANDING TOUGH WEATHER + CHEMICALS

EPDM

EPDM (Ethylene Propylene Diene Terpolymer)

EPDM has the longest proven performance record of all single-ply membranes. Its high-performance synthetic rubber compound provides exceptional weathering in climates across the globe. The material is easy to install and can be either fully adhered, mechanically attached or ballasted. The EPDM system seals are bonded with adhesives and this makes the seams vulnerable over long periods of time. The sealing system/process may lead to maintenance and/or repair issues. Over time, EPDM Rubber Roofs tend to shrink and pull back.

The membranes commonly are black, but white is available.PDM roof membranes can be installed fully adhered, mechanically attached (using batten bars) or ballasted. Most EPDM membranes do not receive surfacings.

Best for: DURABILITY • FLEXIBILITY • UV RESISTANCE

Modified Bitumen Membrane: SBS

SBS (Styrene Butadiene Styrene)

A standard modified bitumen roof system has a base sheet or ply then a waterproofing sheet similar to single-ply. Modified bitumen’s use a traditional waterproofing medium — asphalt — modified with atactic polypropylene (APP) or styrene butadiene styrene (SBS).

SBS modifies the asphalt by forming a polymer network within the bitumen. SBS gives the bitumen rubber-like characteristics and improved resistance to aging and weathering. Most SBS modified bitumen sheets are set in hot mopping asphalt, torch-applied, or adhered with cold-process adhesives. SBS modified bitumen sheets that do not have factory applied granule or foil surfacing need some form of field-applied ultraviolet protective coating.

Best for: COLD ENVIRONMENTS • DURABILITY

Modified Bitumen Membrane: APP

APP (Atactic Polypropylene)

APP (Atactic Polypropylene) is a thermoplastic polymer, which forms a uniform matrix within the asphalt. This enhances the bitumen’s performance by increasing its UV resistance, increasing its flexibility at low temperatures, and improving its flow resistance at high temperatures. APP modified bitumen sheets are applied using a propane-fueled torch. Applicators use the heat to soften the modified bitumen on the underside of the sheet. The sheet’s bottom surface becomes a molten adhesive, which flows upon the substrate and then cools to form a waterproof adhesive bond. Some APP sheets can be applied with cold-process adhesive.

Best for: COLD + HOT ENVIRONMENTS • DURABILITY • UV RESISTANCE

Gutters

Commercial gutters and downspouts play a critical role in prolonging the quality of life of your business’s exterior.

While they might not seem that important, after years of experiencing harsh elements such as rain and melting snow, a system of sturdy rain gutters will make all the difference in how often you need additional exterior and landscaping maintenance.

Play a critical role in prolonging the quality of life of your business’s exterior.

Gravel Stop

A gravel stop is a metal flashing shape attached to roof structure to protect the roof edge against water penetration and to contain a built-up roof and prevent its gravel surface from falling over the roof edge. They are used where flat roofs end to provide a weathertight transition between roof and wall.

Where possible, gravel stops are installed over cant strips or raised curbs. When installed on a concrete or a steel deck, a wood nailer is required. Gravel stops are, in general, about 3/4″ high and formed from copper sheet 8 to 10 feet long. The copper apron extends 4″ onto the roof deck. The sheets are fastened to the roof deck by nails spaced 3″ O.C. The ends are lapped 3″ minimum. The lapped joint on the horizontal flange is set in mastic or elastic sealant. On vertical surfaces, the lapped sheets are held together by a clevis seam. On sloped surfaces, the clevis seam is filled with sealant before assembly.

Provides a professional appearance while securing roofing membrane.

Drip Edge

A drip edge is a non-staining and non-corroding material applied on a roof’s edge to give water the ability to filter out of the roof system. In other words, it is the metal flashing located at the edge of a roof. A drip edge is installed with an intended tilt, which is specifically meant to direct water away from a roof while assuring the foundation of your roof is not exhausted prematurely by holes or fissures.

Drip edges not only act to preserve the appearance of your roof, but they help shield your property from potential damages.

Gutter Apron

Coping Cap

The coping cap is the protective cap or cover on a wall, typically slanted or curved to shed water, protecting the wall from water infiltration from above.

This unique type of cap is designed to cover the top of parapet walls. Many buildings have flat roofs in certain areas specifically for air condoning units and etc. At the edge of these roofs, parapet walls are commonly found, and are vulnerable to leaks if not flashed correctly.

Stops water infiltration into walls that can lead to water damage
