Commercial Roofing in Malden, MA

Durable flat and low-slope roofing for commercial buildings, storefronts, and multi-family properties across Malden and the surrounding towns.

EPDM rubber, GenFlex, and Firestone systems, installed to last.

A commercial roof has one job: protect what is underneath it without interrupting the business inside. When a flat roof starts to leak, it does not just threaten the building, it threatens your inventory, your tenants, and your bottom line. Mark Brady Roofing installs and repairs flat and low-slope commercial roofs across the Malden area, using proven rubber membrane systems built for New England conditions.


We are a family run roofing company with 40 years behind us, and the owners, Mark Brady and Glen Curtis, are on the job themselves. That matters even more on a commercial roof, where the details in the seams, the flashing, and the drainage are the whole difference between a roof that lasts 25 years and one that leaks in five. We are fully licensed and insured in Massachusetts, HIC Registration #(781) 324-4312.


Flat roofing is a different discipline from shingles. It comes down to a watertight membrane, properly bonded seams, and drainage that actually moves water off the roof. We install .060 EPDM rubber and single-ply systems from GenFlex and Firestone, and we install them right the first time.

Commercial & Flat Roofing Systems We Install

We work with proven single-ply systems chosen for durability in our climate, not whatever is quickest to roll out.


.060 EPDM Rubber Roofing. A 60-mil rubber membrane built for flat and low-slope roofs. The extra thickness adds puncture resistance and a longer service life, and EPDM stays flexible through New England's temperature swings, from summer heat to deep winter cold, without cracking. With fewer seams and strong seam bonding, it is one of the most dependable, cost-effective ways to protect a large low-slope roof.


GenFlex Systems. GenFlex single-ply membranes are engineered specifically for flat and low-slope commercial applications, delivering consistent weather resistance and dependable long-term performance.


Firestone Systems. Firestone is a long-established name in single-ply commercial roofing, known for durable membrane systems built to stand up to years of weather and foot traffic.


We help you choose the right system for your building, your drainage, and your budget, and we give you a straight recommendation rather than a one-size-fits-all pitch.

What Makes a Flat Roof Last

A flat roof is only as good as the installation behind it. Most flat-roof failures are not the material, they are the details. We focus on the things that keep water out and the membrane intact for the long haul:


  • Drainage and slope. We make sure water actually moves off the roof instead of ponding and working its way into seams.
  • Bonded, watertight seams. Seams are where flat roofs fail first, so we bond them properly and check them.
  • Flashing at every penetration. Walls, curbs, drains, vents, and skylights all get flashed correctly, because these are the most common leak points.
  • Secure edge and perimeter detailing. Proper edge work keeps wind from getting under the membrane and peeling it back.
  • Membrane fastened for the long term. The system is attached to perform for decades, not just to pass a first glance.


Signs Your Commercial Roof Needs Attention

Catch these early and you avoid a far more expensive problem down the line:


  • Water ponding on the roof for more than a day or two after rain
  • Cracks, splits, or shrinking in the membrane
  • Seams that are lifting, open, or separating
  • Blisters or bubbles across the membrane surface
  • Interior leaks, ceiling stains, or damp insulation
  • Rising energy bills that point to a failing roof system


If you are seeing any of these, an inspection now is far cheaper than an emergency later.


Our Commercial Roofing Process

Common Commercial Roofing Questions

  • How long does a flat commercial roof last?

    A well-installed EPDM or single-ply commercial roof typically lasts 20 to 30 years, depending on the system, the drainage, foot traffic, and maintenance. Even the best membrane can fail early if seams, flashing, or drainage are done poorly, so installation quality matters as much as the material.

  • Should I choose EPDM or another membrane?

    It depends on your building and goals. .060 EPDM rubber is proven, flexible in our temperature extremes, and cost-effective for larger roofs. Other single-ply systems suit different needs. We assess your roof and recommend the system that fits your drainage, budget, and how long you plan to hold the property.



  • Are flat roofs more likely to leak?

    Not when they are installed correctly. Most flat-roof leaks come from poor drainage, bad flashing, or failed seams, not the membrane itself. Because low-slope roofs handle water differently than pitched roofs, the details decide everything. Proper seams, flashing, and drainage are what keep a flat roof watertight.

  • Will replacing my roof shut down my business?

    We plan the work around your operations to keep disruption low. In many cases a business can keep running while the roof goes on above it. We walk you through the schedule and access needs up front so there are no surprises.



  • What thickness EPDM do you install?

    We install .060 EPDM, a 60-mil rubber membrane. The added thickness improves puncture resistance and durability compared to thinner options, which helps the roof stand up to weather, foot traffic, and years of New England seasons.
