Modified Bitumen


Why Consider a Modified Bitumen Roof Coating Application

A modified bitumen roof coating can extend the life of your roof by 10 or more years. Asphalt degradation is a growing concern. UV-rays oxidize the surface of the asphalt and produces a chalk-like residue. As plasticizers leach out of the asphalt, a modified bitumen or “mod bit” roof becomes brittle. Cracking and alligatoring inevitably follows, allowing water to penetrate the system causing blisters, and cracks. Seam failure inevitably follows causing leaks.A black modified bitumen roof absorbs a lot of the sun’s heat in the summer. High temperatures and UV-rays accelerate asphalt degradation. To make matters worse, the heatbuild up raises plenum temperatures thereby increasing cooling costs in the building.

BEFORE: This modified bitumen roof has roof leaks in several locations. To make matters worse, the heat build up raises air temperature surrounding airconditioning units as well as the return plenum. This increases cooling costs in the building.

 

 

 

Modified Bitumen Roof Restoration Process
Cleaning and Surface Preparation

The entire modified bitumen roof was thoroughly washed using a 3,000 psi pressure washer. A biodegradeable degreaser was used to ensure a clean surface. All seams, flashings and penetrations were carefully sealed to render the roof watertight.

Priming

Priming ensures a good adhesion between the roof surface and the elastomeric coating.

Top Coating
30 dry mils of elastomeric roof coating is applied on the entire modified bitumen roof in 2 coats.

A fabric reinforced system is recommended for this job since there are plenty of seams that required sealing. The entire roof was primed with PrimeLock and while the coating was still wet, 40″ wide PolyScrim roofing fabric was rolled out. PrimeLock was reapplied on the fabric to saturate it.

AFTER: A leak-free, seamless roofing membrane now covers the old, weathered modified bitumen roof. The cool roof coating reflects about 90% of the heat from the sun. The roof-top airconditioining units also operate more efficiently since the temperature intake air around the units have been noticeably reduced.
All these benefits for about half the cost of replacement. What more can you ask for?

      I ordered a gallon of Liquid Rubber last summer, and inquired if it could be spread with an adhesive applicator trowel; the sales person was not aware of this having been tried. I tried using a commercially available trowel with 4 sawtooth teeth per inch, and 0.135 inch notch depths, holding the trowel at about a 45 degree tilt.

      Everyone was SUPER helpful and knew the product, properties and application methods well. I applied to product on the trailer in about a 2-hour period one evening. It was tricky with the application, from a novice who had not done this before.

      Donna,your staff and your customer service is the reason we buy from you. You had asked us several months ago if we would write up something for your Website. We wanted to get some additional orders first before coming to conclusions.

      We have completed the resurfacing of our commercial roof back in April and ordered a few more pails for areas where we probably did not apply it thick enough. Just wanted to share these photos with you.

      You have a great product here and we will be ordering for future jobs we have. We were a bit skeptical at first but when it was fully dry it looked as if we installed a new 15,000 sq piece of sheet EPDM.

      This will be the third time our firm has ordered. We completed a project in 05 in the fall and waited for the winter. This was actually the first winter without any leaks. Great product overall.
