Why is my flat roof bubbling?

Blisters form when there are pockets of air or moisture trapped between layers of your roof's membrane or between the membrane and the roof deck. As the sun heats the roof, those pockets expand and stretch the membrane. In severe cases, the membrane will actually crack when the pressure becomes too great.

Why does my roof have a bubble?

Blisters often occur when excessive heat damages the roofing materials. When you have no shade to block direct sunlight to a roof, small blisters can form. Poor attic ventilation is another reason blisters will appear.

Should a rubber roof have bubbles?

Vapour from bonding adhesive

As EPDM is partially breathable, these bubbles are not a huge problem long-term, and will gradually settle down over time. However, in severe cases, it could mean that the membrane has not bonded correctly, and the membrane may need to be peeled back and re-applied.

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.

Will bubbles in rubber roof go away?

Will bubbles in the rubber roof go away? No. The bubbles in the rubber roof will not go away. They may shrink, but the constant heating and cooling of the roof will cause more problems the longer the bubble remains in the roof and is not repaired.

How do I know if my rubber roof is bad?

Rubber roofing Looks wrinkled and not tight

When wrinkles or ripples appear in the rubber it could indicate that moisture has entered under the rubber membrane and deteriorated the adhesive that glues the rubber to the insulation board. The rubber wrinkles as it is no longer glued down in that spot.

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.

What does roof blistering look like?

Blisters look like pockmarks and are characterized by a loss of asphalt, sometimes to the extent that you can see the mat, as in this photo. The mat is visible in these close-ups. You don't need to identify the cause of blistering.

Should a TPO roof have bubbles in it?

A TPO roof doesn't have “bubbles” UNLESS it was fully adhered and the contractor didn't let the bonding adhesive flash off. Now, there may be wrinkles from the application which are “normal” if they are minor. They will go away when the weather warms up…not in a year or two.

How do you get wrinkles out of a rubber 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 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.

Are EPDM roofs any good?

An EPDM roof lasts a long time. In fact, even with only minimal attention, an EPDM roof can last 50 years or even longer. New formulations for the rubber make these roofs virtually impervious to radiation and damage from UV rays. They are wind resistant and stand up well to hail as large as three inches across.

Do flat roofs always leak?

So leakage is not strictly an issue with flat roofs. The reality is that a flat roof can often last up to 30 years without issue if it is properly installed and maintained.
