Commercial Roofing

 

 

 

BUILT-UP ROOFING MEMBRANE


Built-up roofing, or “BUR” as it has commonly known, is essentially your standard tar-
and-gravel roof. It is built with multiple layers (piles). This is a flexible roof type as the
number of layers can be varied to help control costs or meet certain durability
requirements you may need to address. It is a very old low-slope roof system and is one
of the most cost-effective and tough roofing types available today.



METAL ROOFING


Metal roofing is an extremely popular commercial roof type because there are so many
kinds of metal materials available for use in such a roofing system, including:


 Corrugated galvanized steel
 Aggregates of zinc, aluminum, and silicon-coated steel
 Metal tile sheets
 Copper
 Aluminum
 Stainless steel
 Stone-coated steel
 Tin
 And lead


Since metal is susceptible to rusting, protective surface layers are added to manage
damage from prolonged exposure to sunlight and other environmental dangers. Metal
roofing also has the advantage of having an attractive, finished look, but when budget
and durability are of the utmost importance, it’s wise to go with what works best rather
than what looks best. Metal roofs do, however, have strong fire resistance ratings, and
are both stronger and more durable compared to traditional commercial roofing options.
They also help create a more sustainable design for your building.

 


MODIFIED BITUMEN ROOFING


Reinforced roof fabrics are applied to act as “carriers” for bitumen, which is later cut and
installed in layers. These roofing systems are generally fastened to commercial rooftops
as two-ply systems, adhered to the roofing deck for maximum stability and protection.
Maintenance of modified bitumen roofs are simple and can typically be handled with
annual inspections and cleaning. They offer enhanced tensile strength compared to
most other flat roof types that experience regular foot traffic, and that means if you
anticipate a lot of activity on your commercial building roof, modified bitumen may be
ideal.

 


 


EPDM


Thermoset roof system offers a long-lasting durability and versatility, paired with a
simple installation and ease of maintenance/repair when compared to most other
commercial roof types. EPDM boasts a strong resistance to ultraviolet light and ozone
and is constructed from a single-ply rubber material.
Other benefits include great flexibility in colder temperatures; resistance to some acids,
solvents, and alcohol; and reflective properties that help lower cooling costs.

 


 


TPO


Thermoplastic Polyolefin (TPO) and Poly Vinyl Chloride (PVC) roofing systems are
lightweight, highly reflective, and provide excellent weathering and resistance to UV
light, punctures/tears, and most chemicals, including oils, animal fats, and bacterial
growth. The seam strength offered by thermoplastic roofs make it ideal for second-
generation applications, too. The nature of these resistances makes thermoplastic roof
membrane popular for restaurants and other businesses that emit oils and/or fats from

their ventilation systems. Other benefits range from a high-temperature tolerance to
high resistance to fire and high winds.
