Liquid EPDM Coatings Are Effective Roofing Material


EPDM rubber (ethylene propylene diene M-class rubber), a type of synthetic rubber, is an elastomer which is characterized by wide range of applications. The E refers to Ethylene, P to Propylene, D to diene and M refers to its classification in ASTM standard D-1418. The “M” class includes rubbers having a saturated chain of the polymethylene type. EPDM exhibits satisfactory compatibility with fireproof hydraulic fluids, ketones, hot and cold water, and alkalis, and unsatisfactory compatibility with most oils, gasoline, kerosene, aromatic and aliphatic hydrocarbons, halogenated solvents, and concentrated acids.
Liquid Roof Provides amazing results to those who used it, and they are highly satisfied, you can read our testimonials. Liquid EPDM coatings are just as effective roofing material as the sheet form coatings commonly used in the roofing industry. In many cases, they are better. They combine all the benefits of EPDM rubber roofing with the flexibility of using a liquid.
EPDM rubber is used in vibrators and seals; glass-run channel; radiator, garden and appliance hose; tubing; washers; belts; electrical insulation, and speaker cone surrounds. It is also used as a medium for water resistance in high-voltage polymeric cable jointing installations, roofing membrane, geomembranes, rubber mechanical goods, plastic impact modification, thermoplastic, vulcanizates, as a motor oil additive, pond liner, electrical cable-jointing, RV roofs, and chainmail applications.

Roof Leaks Repair Procedures

There are too many different types of roofing membranes to tailor emergency repair procedures for each. However, if literature cannot be located and/or if procedures are not detailed for emergency repairs, the following guidelines are suggested:

Protect the interior: Control the spread of water in the interior by collecting the water in containers or by using plastic sheeting to protect the building contents.

Remove excess water from the roof: Check roof drains and scuppers to be certain that they are open and functional. A frequent cause of roof leakage and roof collapse is excessive ponding on the roof surface due to clogged drains and/or scuppers.

Caution should be exercised when clearing debris from drains. Significant suction forces can be created by draining water, which can suck tools, hands, or arms placed within these vortices quickly into the drain.

Locate the source of a leak: In attempting to determine the source of a leak, locate the point on the roof surface above the area of leakage in the building interior. From this point, first check the condition of rooftop mechanical equipment, then check all flashings at terminations and penetrations. Second, if the system is ballasted remove ballast from the immediate leak area, then check the membrane surface for cuts, splits, or punctures. Finally, check the seams (laps) in the roofing membrane.
Perform emergency repairs: Once the source of a leak is located, the materials and procedures which will cause the least amount of damage to the roofing membrane should be chosen. Please refer to the following list of suggestions to perform emergency repairs by roofing system type.

Roof Leaks Identification

Step 1:
The first and perhaps most obvious place to look for a roof leak is directly above the leak in a ceiling or exterior wall. Use a flashlight to inspect the attic floor over the leak while it's raining. Look for standing water, water stains, mold, wet insulation or other exposed insulation.
Step2:
Examine the underside of the roof for wetness or mold around points of penetration (plumbing vents, chimneys), wherever different roof planes intersect (valleys) and near dormers. These symptoms indicate holes in the flashing or faulty flashing installation.
Step3:
A leak away from such locations suggests a problem in the roofing material. Keep in mind that water may travel sideways before passing through a joint in the roof sheathing, and may travel in a horizontal joint before falling on the floor or ceiling.
Step4:
Take measurements from points inside that you can also locate from outside. Measure down from a ridge and horizontally from the center of a valley or sidewall; or measure distances from a chimney or other point of penetration.
Step5:
If your ceiling is attached to roof rafters, as would be the case for a cathedral ceiling, all you can do from inside is take the measurements that will help you locate the leak externally, and attempt to control the damage internally.
