MODIFIED BITUMEN (Torched
Applied Roofing) A commercial roofing waterproofing
membrane either granulated or smooth surfaced composed of
asphalts blended with polymers and reinforced with polyester
fabric or fiber glass mat. Torch down refers to the application
method of using heat from the torch to melt the adhesive embedded
in the material. Hot mop refers to the application method
of using hot asphalt from a kettle as the adhesive.
BUILD-UP ROOFING
Commonly referred to as a Tar & Gravel roof.
By today's codes this commercial roofing consists of the use
of steep asphalt (normally type III) instead of coal-tar pitch
as used by our forefathers. The type of substrate dictates
the type of insulation and base sheet materials to be used,
ply's of felt (generally 3, 4, or 5) are installed by integrating
hot asphalt between each ply installed, to build an overlapping,
redundant system. This system is then flooded with more hot
asphalt in order to seed the application of 400 to 600 pounds
of gravel per 100 square feet (1 square).
POLYURETHANE FOAM (
Spray in Place)
This commericial roofing system is designed strictly
for use on commercial flat roof applications. Its sprayed
in place application creates a monolithic seal over the entire
roof. It is covered with aggregate and the use of electrometric
coatings are limited to areas the aggregate doesn't cover,
such as parapet walls, canted areas, and protrusions. Please
see our link on Spray Polyurethane Foam.
METAL ROOF COATING
A single component, water based 100% acrylic, latex
coating. Ideal forcommericial roofing due to, easy application
over prefabricated metal roof panels as well as corrugated
galvanized sheeting. This flexible system stays cool in sunlight
by reflecting 90% of the suns rays significantly reducing
air conditioning costs while insuring water-tight integrity.
