Built Up Roof System

Elevate Modified Bitumen Roofing Systems provide architects, contractors, and building owners with the ability to design new roofs or re-roof systems that fit a variety of climates, environments, and applications. Material flexibility easily adapts to building movement while simple, economical installation options help save time and money.

But-what is BUR roofing exactly, and how can it offer such a variety of benefits?

As a system, built-up roofing (BUR) is a type of asphalt roofing that has been around for more than 100 years. It is one of the most common materials used on low-slope or flat roofs. Despite the system's established history, BUR technology continues to progress, especially in the hands of Elevate engineers, chemists, and technicians who develop and test the latest roofing advancements.

Elevate offers Ply IV (4) and Ply VI (6) asphalt impregnated, glass fiber mat reinforced roofing felts that can be installed in multiple layers with a flood coat and aggregate. They can also be used in combination with modified bitumen. Ply IV (4) and Ply VI (6) felts offer excellent durability and ease of application when constructing Elevate Built-Up Roofing (BUR) Systems.

BUR tends to be a preferred solution for low slope roofs, as it provides a continuous sealed surface to resist water penetration effectively.

FEATURES AND BENEFITS

• EASY TO APPLY: Offered in Ply IV (4) and Ply VI (6) asphalt-impregnated roofing felts, which provide durability and ease of application.
  

• DURABLE: Reinforced with a glass fiber mat, the felts are installed in multiple layers with hot asphalt and surfaced with a flood coat and aggregate or mineral-surfaced SBS membrane.
  

• FLEXIBLE: System flexibility allows specifiers to select the cap sheet suited to job conditions and local installation practices.
  

• STRONG: Thanks to its continuous sealed surface, built-up roofing effectively resists penetration from moisture. Built-up roofs also offer ultra-violet protection, fire-resistance, and minimal maintenance costs.

What goes into Elevate BUR products? Rounds of testing, years of commercial-grade technology and expertise, and layers of proprietary material. Elevate products are engineered with a unique elastomeric blend of polymers combined with select grades of refined asphalt for extraordinary flexibility and strength.

Elevate SBS or APP "Cool" UltraWhite Cap Sheet
The cap sheet is your BUR system's first line of defense against the elements. Two-ply SBS or APP assemblies incorporate high-quality Elevate SBS or APP Base and Cap Sheets.

Elevate Multi-Purpose Cold Adhesive
Elevate multi-purpose cold adhesive is modified with SBS. This modification increases adhesion to insulation and between piles for greater wind uplift resistance.

Elevate SBS or APP Base Sheet
Elevate SBS or APP base sheets support your BUR roof system from the bottom up by protecting the membrane, controlling moisture, and serving as a flame retarder for torch-applied membranes, among other benefits.

Elevate ISOGARD™ HD Cover Board
The cover board installs between the insulation and membrane. It serves as a barrier, preventing hot asphalt, certain adhesives, and foot traffic from damaging the insulation or other BUR layers. Elevate ISOGARD™ HD is a 12.7 mm thick polyiso board that combines impact resistance and installation ease in a single durable product.

I.S.O Twin Pack Insulation Adhesive
I.S.O twin pack insulation adhesive is a two-component, low-rise polyurethane adhesive designed for anchoring roof insulation to substrates and adhering multiple layers of insulation.

Elevate Fastener & Plate
Use Elevate fasteners and plates to ensure product compatibility and quality.

Elevate ISO 95+ GL Insulation
Elevate ISO 95+ GL flat or tapered insulation provides additional protection for the structure and promotes energy savings. Tapered polyiso insulation, in particular, is ideal for a substrate slope that does not permit efficient damage.
