FEATURE SELECTION FOR PROPOSED ROOF SYSTEM

 

Select the roof system features of your choice by placing a check mark below in the appropriate margin. Then add any additional features and comments to the comments section at the end of the form. CIA will be pleased to prepare a bid proposal utilizing a roof system which includes the features you selected.

ROOF MEMBRANE

Sheet membranes: Custom job fabricated membrane:
____ 2, 3, & 4 plies built up membrane 30-60 mils ____Single membrane thickness1,500 to 2,000 mils
____ Membrane plies are 36" wide with seams that run the full roof length, plus seams at roll ends, at penetrations and at the roof edge. ____Membrane is one monolithic sheet no seams.
____ Method of attachment to the roof deck: loose laid and ballasted with aggregate, or mechanically Fastened with screws and plates, or glued with adhesive. ____Chemically self adhered- bonds chemically and becomes unitized to the under lying surface. The roof membrane is 100% fully adhered.
____ Sheet metal counter flashing is necessary to water-proof membrane ends, all penetrations through the roof, and at the perimeter. ____Membrane is self - flashing --- chemically adhering to both horizontal and vertical surfaces. Counter Flashing is not required.

 

 

WATERPROOF

____Membrane is a vapor barrier. ____Membrane is not a vapor barrier - Breather perm rate of 3.0.
____Traps leaked water in under the roof. ____Permeable Self Drying allows trapped water membrane to evaporate and pass out through the membrane.
____Leakage and condensation saturates the roof and insulation. ____Membrane will not saturate from leakage or roof and insulation. Condensation, water vapor passes to the outside.
____Trapped water requires the roof & insulation to be removed and replaced. ____Membrane insulation will not absorb liquid. The water will evaporate out.
____Wet roof insulation causes loss of energy efficiency and corrosion of the deck. ____Membrane is Breathable allowing vapor to pass through to both the interior or exterior.
____ Thin membrane easily punctured. ____The entire membranes 1,500 mil thickness is waterproof, additionally the membrane is protected by a " to 1" blanket of aggregate.
____ Source of leaks are difficult to define as water can travel long distances between the membrane plies or the membrane the roof deck. ____Should a leak occur its source is easy to locate since the membrane is fully adhered, water and can only flow vertically through a puncture.
____Membrane is easily damaged and leakage from foot traffic, hail, abrasion, wind blown debris, trapped moisture and thermo movement. ____1,500 mil membrane with 1" blanket of aggregate is highly resistant to damage and leakage.
____ Repairs are difficult due to trapped water and the location of the leak is not easily found. ____Easily repaired via application of sealant or to re foam an area. With scheduled maintenance THE ROOF need never be replaced
____ Catastrophe potential for loose membrane to be blown off in a storm. ____Membrane is 100% adhered to structure.

TESTED RATED

____ UL 790 CLASS A FIRE RATED

____ UL wind up lift rating to I - 90

____UL 790 CLASS A FIRE RATED

____UL wind up lift rating to I -165

ENERGY EFFICIENCY

____ Membrane is black absorption of heat is transferred into the building. ____The URETHANE membrane is also an insulation, it repels heat from the outside before it can enter into the building, R-11 at 1,500 mils.
