This portion of the website was created to educate the consumer a little bit about roof systems that are readily available in the market “enjoy the learning experience!”

BUR - Built up Roof
Modified bitumen - polyester reinforced , rubberized asphalt roll,with a granule surface or smooth surface
Single Ply - reinforced, energy rated membrane(similar to plastic)
Green Roofs - Landscape and paver design for your roof ideal for penthouse apartments with large balconys  or tall buildings that want to put use to there roof top spaces
EPDM - Black Rubber
Foam Roof Systems - Spray on insulation and coating with sand blasted granules on surface
Mechanically attached - membrane or insulations that are fastened with screws and plates to the structure
Fully adhered - Membrane or insulations that are applied in adhesive
Décor profile systems - gives the appearance of a standing seam metal roof but in reality is a flexible membrane that is ideal in forming radius’s
Cool Roofs - sprayed or rolled applied system over your existing roof “ Legally it’s a new roof” energy star product and approved by the cool roof council
Tapered insulation - insulates building and provides positive drainage
Lightweight concrete - looks like there pooring a concrete slab but in reality this is a roof substrate Ideal when installing a top of line roof system positive drainage, biodegrable product, preserves the life of the roof system, contains the tempeture of your building

Definitions:
Aggregate - materials used in construction, including sand, gravel, crushed stone, slag, or recycled crushed concrete
Asphalt - is a sticky, black and highly viscous liquid or semi-solid that is present in most crude petroleums and in some natural deposits sometimes termed asphaltum
Coal tar - is a brown or black liquid of high viscosity, which smells of naphthalene and aromatic hydrocarbons. Coal tar is among the by-products when coal is carbonized to make coke or gasified to make coal gas. Coal tars are complex and variable mixtures of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds
Bonding adhesive -  is a mixture in a liquid or semi-liquid state that adheres or bonds items together. Adhesives may come from either natural or synthetic sources
Ballast - ballasted roof as a membrane roofing system that is usually loose laid on the roof deck and held in place by the weight of stone aggregate or precast concrete pavers. The weight of the stone or pavers employs the force of gravity to hold the roof membrane in place and counter the uplift forces of wind.
Heat weld - Heat welding is a process of thermo-fusing or heat sealing separate pieces of resilient roofing products together at a seam or joint
Hand Welder -welding device typically used when detailing
Robotic Welder -a device used when welding long continuous seams
Tar Kettle- is a machine used in preparing asphalt to be installed at the correct tempature usually contains a gas powered engine attached to pump hot asphalt to the roof
Hydraulic Hoist- used in hoisting heavy materials up a high rise building
Underlayment- Roof underlayments are designed to protect the roof sheathing and structure from moisture and penetration. Advances in materials and technology have created more options and increased manufacturers’ warranties.
Low rise foam - Spray applied polyurethane foam roofing adhesive.
Low-rise, two - component expanding polyurethane foams are becoming ever popular as roofing adhesives to adhere membranes and insulations directly to the roof deck, for a totally non-penetrating, fastener free, roof system application.
Fleeceback - is a fleece laminated to the back of a single ply roll or epdm acts as a substrate for the membrane. Ideal in recover systems without having to use insulations
