Commercial Roofing Solutions for Your Business
When your commercial property needs roofing work, you need a contractor who understands the unique challenges that come with large-scale projects. At Cran-Marsh Inc., we bring over 50 years of family-owned expertise to every commercial roofing project we undertake. Our experience spans across New England, Cape Cod & The Islands, providing businesses with reliable roofing systems that protect their investments and operations.
Commercial roofing differs significantly from residential work in terms of scale, materials, and engineering requirements. We specialize in flat and low-slope roofing systems commonly found on warehouses, office buildings, retail spaces, and industrial facilities. Our team possesses the technical knowledge and equipment necessary to handle projects ranging from small storefront repairs to complete roof replacements on expansive manufacturing facilities.
Types of Commercial Roofing Systems We Install
Our expertise covers the full spectrum of modern commercial roofing technologies. TPO (Thermoplastic Polyolefin) roofing has become increasingly popular due to its energy efficiency and durability. This single-ply membrane reflects UV rays effectively, reducing cooling costs by up to 30% during summer months. We install TPO systems using either mechanically attached or fully adhered methods, depending on your building’s specific requirements and local building codes.
EPDM (Ethylene Propylene Diene Monomer) rubber roofing remains a cost-effective choice for many businesses. This synthetic rubber membrane offers excellent weather resistance and can last 20-30 years with proper maintenance. We also work with modified bitumen systems, which provide multiple layers of protection and perform exceptionally well in areas with significant temperature fluctuations. For buildings requiring maximum durability, we install built-up roofing (BUR) systems that combine multiple layers of bitumen and reinforcing fabrics to create a continuous sealed surface.
The Commercial Roof Replacement Process
Understanding when to replace rather than repair your commercial roof requires careful evaluation. We begin every project with a comprehensive inspection that examines not just the visible surface but also the underlying deck structure, insulation layers, and drainage systems. Our assessment includes core sampling to determine moisture content within existing roofing layers and infrared scanning to identify hidden wet areas that could compromise your new roof’s performance.
Once we determine replacement is necessary, we develop a detailed project plan that minimizes disruption to your business operations. This includes scheduling work during off-hours when possible, implementing safety protocols to protect employees and customers, and establishing clear zones for material staging and debris removal. We coordinate with your facility management team throughout the project, providing daily updates on progress and addressing any concerns immediately.
Energy Efficiency and Building Performance
Modern commercial roofing systems play a crucial role in overall building energy performance. We help businesses throughout New England, including Cape Cod and the Islands reduce their environmental footprint and operating costs through strategic roofing choices. Cool roofing materials with high solar reflectance can reduce roof surface temperatures by up to 50 degrees Fahrenheit compared to traditional dark roofing materials. This temperature reduction translates directly into lower air conditioning loads and extended HVAC equipment life.
Beyond material selection, we focus on proper insulation installation to meet or exceed current energy codes. Polyisocyanurate insulation boards provide excellent R-value per inch of thickness, while maintaining compatibility with various roofing membranes. We also address thermal bridging through fasteners and penetrations, ensuring your building envelope performs optimally year-round.
Maintenance Programs and Long-Term Value
Protecting your roofing investment extends well beyond initial installation. We offer comprehensive maintenance programs designed to maximize your roof’s service life while preventing costly emergency repairs. Regular inspections allow us to identify and address minor issues before they develop into major problems. Our maintenance services include:
- Bi-annual inspections covering all roofing components, flashings, and drainage systems
- Debris removal from drains, gutters, and rooftop equipment areas
- Sealant and caulking renewal at penetrations and termination points
- Documentation and reporting with photographs and recommendations for budgeting purposes
Industry Certifications and Quality Assurance
Our GAF Master Elite Certification and CertainTeed Master Shingle Applicator status demonstrate our commitment to installation excellence. These certifications require ongoing training, proper insurance coverage, and proven track records of quality workmanship. Less than 2% of roofing contractors achieve Master Elite status, placing Cran-Marsh Inc. among the industry’s most qualified professionals.
Being family owned and operated for over five decades means we’ve built our reputation on trust, competence, and honesty. We’re big enough to handle substantial commercial projects yet small enough to provide personalized attention to each client’s specific needs. This balance allows us to deliver exceptional results while maintaining the collaborative partnerships that define our approach to business.
