Roofing membrane: The layer or layers of waterproofing products that cover the roof deck.
Roofing tape: An asphalt-saturated tape used with asphalt cements for flashing and patching asphalt roofing.
A roofing membrane not attached to the substrate.
Loose Steel Lintel
Lintel made of structural steel shape (usually angle) that is set loose and built into masonry construction.
Waterproofing membrane material can be considerably more expensive than just using felt. Most professional roofers recommend the extra protection, and for a do-it-yourselfer, it's good insurance against a leaky roof.
Rolling Out Builder's Felt ...
Waterproofing membrane systems include both negative and positive side waterproofing. Positive side waterproofing systems are applied to the face of the element that is directly exposed to moisture, the exterior face.
A piece of roofing membrane consisting of one or more narrow plies of felt usually moped in hot to seal the edge of insulation at the end of a day's work.
substrateThe surface upon which the roofing or waterproofing membrane
is placed, i.e. structural deck or insulation.tapered edge stripA tapered insulation strip used to elevate the
roofing at the perimeter and at penetrations of the roof.
When installed properly, it provides a watertight roofing membrane with a relatively long service life. The earliest built-up roofing was made of tar-saturated felts installed in 2-5 layers (plies) with a coating of hot tar between alternate layers.
Ply A layer in a built-up roofing membrane.
Point A fee charged by lenders at settlement equal to one percent of the loan amount. Points are charged so as to raise the lender's yield above the apparent interest rate.
It's also wise to install at least one row of rubberized asphalt roofing membrane, such as Grace Ice and Water Shield, which reduces the chance of roof leakage when ice forms at the eaves and water from melted snow builds up behind it.
If the existing roof covering (tiles, slates etc.) is being replaced it makes sense to insulate over the rafters and fit a breathable roofing membrane (waterproof, but air permeable to ventilate the roof structure).
Reinforced Membrane - A roofing or waterproofing membrane reinforced with felts, mats, fabrics, or chopped fibers.
Replacement - the practice of removing an existing roof system and replacing it with a new roofing system.
Moisture Relief Vent: venting device through the roofing membrane to relieve moisture vapor pressure from within the roof assembly.
Mole Run: a meandering ridge in a roof membrane not associated with insulation or deck joints.
Reinforced Membrane: A roofing membrane that has been strengthened by adding polyester scrims or mats, glass fibres or other material.

AIR POCKET/BLISTER-A bubble in the roofing surface formed by water vapor expanding between the layer of a built-
up roofing membrane. This condition can reduce the useful life of the roofing surface and is conductive to moisture ...
CANT STRIP - A beveled support used at the intersection of the roof deck with vertical surfaces so that bends in the roofing membrane to form base flashings can be made without breaking the felts.
Galvanized step flashing
Galvanized coil stock
26-gauge galvanized sheet steel (for prefabricated pieces)
Galvanized front base flashing
Self-adhering roofing membrane (ice and water barrier)
Polyurethane caulk
Drive-in expanding anchors ...
the format of the original, this book begins with an overview and introduction by Professor Tom Woolley discussing issues in green building before moving on to consider eight building component types: fencing products, flat roofing membranes, ...
Polyvinyl Chloride has some potentially serious toxicity problems during manufacture and disposal. I don't recommend the use of materials containing PVC such as: pipes, vinyl siding and some roofing membranes.
They also may paint or spray surfaces with a waterproofing material, or attach waterproofing membrane to surfaces. When dampproofing, they usually spray a bitumen-based coating on interior or exterior surfaces.
