Single Ply Roofing System by Mast Roofing

If your building endures extreme temperatures, frequent high winds, damaging hail storms, snow storms, and even fire hazards, you need extreme roof protection.
MAST Roofing can provide you with security and peace of mind through our Single Ply Membrane Roofing Systems.


Recognized by major code approval agencies.
This Elvaloy®-modified PVC provides rugged protection from the elements. Its unique chemical formulation is naturally fire-resistant, making Flexion an excellent choice for both new and re-roofing applications.


Durable in the harshest of environments
Made with Chlorosulfonated Polyethylene (CSPE), Hy-Crown has proven its durability and longevity over decades of exposure in the harshest environments.
Conklin’s highly reflective roofing coatings also provide significant energy savings. By reflecting up to 85% of the sun’s energy away from the roof, cooling costs are drastically reduced. Temperatures of a roof surface are reduced by 80% or more when comparing a traditional black roof with a Conklin white coating system.

Saving Energy Pays for Installation

Energy Star The white surface reflects up to 85% of the sun's heat, creating a significant saving in reduced cooling costs. This "cool roof" energy saving has prompted state and federal governments to offer incentives for retro-fitting light colored roofing.
We strive to be leaders in promoting energy conservation , and reflective roofing is markedly energy efficient. Check with your local utility provider or go to for additional details on tax rebates and credits.

Featured Customer Review

It is my pleasure to write this letter of reference for David Mast and his company, Mast Roofing.

During a time of financial crisis in California Schools, we found ourselves needing roofing solutions for several older, portable buildings in the District. These buildings had been plagued with leaks for many years and we had no choice but to find a solution that would solve the problem. However, it was very important for us to contain costs at a time when financial solvency was a daily concern.

Mast Roofing provided a very reasonable quote, completed the work in a timely manner, and they worked very well with my maintenance staff to accommodate our scheduling needs. The installation crew worked quickly and professionally and we have been very satisfied with the results.

My maintenance manager also reported that Mast roofing went "above and beyond" when doing the critically important preparation for the roofing upgrade to ensure that we would have a long-term solution.

I highly recommend the company and their product.
