At Henris Roofing, we treat every commercial installation as a long-term investment in your property, and we approach the work with the same care we have brought to roofing projects for over 80 years.

Planning the Right System for Your Building

Before a single roll of membrane or panel is delivered, we start with an assessment of how your building is actually used. A warehouse with heavy rooftop mechanical equipment has different structural and drainage demands than a retail plaza, a medical office, or a manufacturing facility with process exhaust. We evaluate roof deck condition, existing insulation values, slope, penetration points, and how water is currently being directed off the surface. This planning phase is where costly surprises are prevented, and it is why we never rush it.

We provide free estimates with no conditions, so you can understand the scope and options before committing to anything. During this stage we walk you through the material choices that fit your building profile, your energy goals, and your timeline. Whether you are constructing a new facility or replacing an aging system, the planning conversation shapes every decision that follows.

Commercial Roofing Systems We Install

Different buildings call for different systems, and matching the material to the structure is where experience pays off. We regularly install and work with a range of proven commercial roofing options.

  • TPO and single-ply membranes: reflective, energy-efficient surfaces well suited to flat and low-slope roofs seeking to reduce cooling loads.
  • EPDM rubber roofing: a durable, flexible membrane that performs reliably through freeze-thaw cycles and temperature swings.
  • Modified bitumen and built-up roofing: multi-layer systems offering strong resistance to foot traffic and mechanical wear.
  • Metal roofing: long-lasting panel systems ideal for facilities that want minimal maintenance and a clean profile.
  • Solar-integrated roofing: as a Timberline Solar Roofing Contractor and Energy Solar Certified installer, we can integrate energy production directly into the roof system rather than mounting it as an afterthought.

How We Handle the Installation

Installation begins with protecting your operations. Commercial buildings often stay occupied and active during a roof project, so we sequence the work to minimize disruption to your business, your customers, and your employees. We stage materials thoughtfully, keep access routes clear, and coordinate delivery schedules around your peak hours whenever possible.

From there, our crews remove or prepare the existing surface, address any deck repairs, and install insulation to meet the thermal targets we established during planning. Membrane or panel installation follows, with careful attention to seams, fasteners, flashing details, and every penetration where leaks most commonly begin. Rooftop units, drains, scuppers, and edge metal all receive detailed treatment, because these transition points determine how long a roof truly lasts. Throughout the project we respect your property and are mindful to clean up after ourselves, leaving your site orderly at the end of each workday.

Credentials and Standards Behind the Work

Manufacturer certifications matter on commercial projects because they tie directly to warranty coverage and installation quality. Henris Roofing holds GAF Master Elite status and ShingleMaster Pro recognition, distinctions earned by contractors who meet rigorous training, workmanship, and reliability requirements. These credentials mean the systems we install can qualify for enhanced warranty protection that non-certified installers simply cannot offer.

We also build environmental responsibility into our process, using best practices and materials that reduce waste and improve building efficiency. Reflective membranes and solar-ready systems help lower energy consumption, which translates to measurable operating savings for property owners across Petaluma, CA and surrounding areas. Serving clients throughout Petaluma, Penngrove, Novato, Rohnert Park, Cotati, Santa Rosa, & Sonoma, CA, we combine that environmental awareness with practical, hands-on execution.

Support That Continues After Installation

A roof project does not end when the last panel is fastened. Commercial buildings face storms, equipment changes, and unexpected events, which is why we offer 24/7 emergency service to keep small problems from escalating into interruptions. As a professional, reliable, efficient, and established company that supports our local community, we stand behind the systems we install.
