Restoring or Maintaining Your Modified Bitumen Roofing Membrane

 

Dark surfaced membranes, such as modified bitumen roofing substrates, absorb a majority of the sun’s UV rays generating excessive heat on the roofs surface.  This heat gain can cause several damaging effects to your modified bitumen roofing membrane, including: premature aging, splitting and cracking, blistering, and overall brittleness of the membrane.  These symptoms are the primary cause your roof begins to leak. 

The Good News

Thankfully, if caught before irreversible damage has occurred, these destructive results are easily fixed with a high quality elastomeric roof coating.  National Coatings has specifically formulated asphaltic roof coatings for modified bitumen roofing membranes.  These coatings have unique bleed-blocking properties leaving your newly coated roof, exceptionally white and highly reflective, protecting your roof from the sun’s harsh UV rays.  

Maintain or Restore Your Roof

Depending on the condition of your roof, a roofing contractor can either install a roof maintenance system, such as an AcryShield Roof Management (ARM) System or a roof restoration system, such as an AcryPly Roofing System. The ARM systemmodified bitumen roofing (shown below) for modified bitumen roofing substrates uses a base coat directly over your existing roof.  Customized local reinforcement is put in place in areas where extra support is needed.  Then the highly reflective, bleed-blocking top coat is sprayed over the entire roof surface.  This imbeds the local reinforcement in-between the base and top coats, giving your roof the strength and protection it needs in those areas that have extra damage. 

 

The AcryPly Roofing System (shown below) for modified bitumen roofing substrates is an excellent alternative to a roof tear-off and provides needed reinforcement across the entire roof substrate.  This modified bitumen roofingsystem uses a base coat over the existing roof, followed by LiquiSeal asphalt emulsion, which fills in any cracks and voids, providing an added level of waterproofing and an excellent foundation upon which to build the balance of the membrane. Then polyester fabric is rolled out over the entire roof substrate for an extremely durable reinforcement layer. Next, the base coat is sprayed, allowing the fabric to be fully imbedded in-between the LiquiSeal and base coat, providing strength and support to your damaged roof.  Finally the highly reflective, bleed-blocking top coat is sprayed, leaving you with a fully-reinforced, custom installed roof that eliminates the need for a costly tear-off. 

Greatest Benefits of Coating an Existing Modified Bitumen Roofing Substrate

These roofing systems are 100% waterproof, renewable, and sustainable. They are installed on the exterior of your building with minimal noise disruption to your facilities daily environment. You can re-coat your roof several times without ever having to tear the roof off, saving you a great deal of money and allowing your business to stay open during renovation.
