Any gaps can be filled with an expanding foam adhesive to stop the trapped air lifting the membrane. If you are installing a timber deck over the insulation a cheap visqueen membrane can be installed under the timber deck, this is also a great way of ensuring that the expanding air doesnt cuase the membrane to lift.
How do I get rid of bubbles in my flat roof?
The true fix to cracks or membrane ruptures is to apply a brand new coating to your flat roof. Before applying be sure to clean the roof of all debris and particles. The next step is to place a primer down that is compatible with your roof deck. Apply the coating and reinforce the coatings with fiberglass mesh strips.
What causes a rubber roof to bubble?
When the rubber membrane is bonded too quickly, and prior to the adhesive drying, bubbles will appear under the membrane caused by the trapped vapour from the adhesive. In time the bubbles will decrease as the membrane is partly breathable. In the most severe cases the membrane may need to be peeled back and re-bonded.
How do you get wrinkles out of EPDM roof?
Using a heat gun, gently heat up the surface of the EPDM membrane and smooth out the creases using a silicon roller. Fig 2: Heating the EPDM membrane and smoothing with the silicon roller. Work quickly and efficiently across the creased area without remaining in one place for too long.
What are common problems with EPDM roofs?
Three most common problems with Rubber Roofs is improper installation, shrinkage and the seams. While the rubber roofs are known to be durable, they also need maintained. EPDM roofs are fully adhered or as many call it glued down. The system is not attached mechanically.
What causes EPDM to swell?
EPDM is a hydrocarbon polymer, which swells excessively in hydrocarbon fluids such as mineral oils and hydrocarbon fuels, because of lack of polar groups in the polymer chain. An example of its swelling behavior is presented in Table 1.
How do you fix a bubble in a foam roof?
If you can get the area clean between the foam and the old roof, spray a thin coat of foam and re-adhere the foam, or cut out the uplifting foam and respray the area, then apply an acrylic coating. Moisture trapped while foam is being applied can cause high spots, or “blisters” in the foam.
How long does an EPDM roof last?
EPDM roof membranes remain stable over time and can have a life expectancy of over 50 years. ** Made from synthetic rubber, EPDM roofing membranes have two primary ingredients, ethylene and propylene, which are derived from oil and natural gas.
Can EPDM roofs be repaired?
It can be repaired, but a repair may have to be done again before the roof is worn out because of abnormal movement in the membrane. The roof has torn at the overlap at the outside edge of the seam. If it was caused by 3rd party damage, repair it with new EPDM material or EternaBond repair material.
