Your commercial property faces relentless sun, monsoon flooding, and the constant wear of HVAC units and foot traffic. A compromised roof doesn't just risk inventory—it halts operations, disrupts tenants, and drains your budget. Mulcock Roofing specializes in flat and low-slope systems that keep Tempe businesses watertight and energy-efficient year after year.
Tempe's dense commercial corridors—from Mill Avenue to the Elliot Road tech hubs—demand roofing solutions that balance durability with cost. TPO, EPDM, and modified bitumen membranes each offer distinct advantages for Arizona's climate, and choosing the wrong system can cost you tens of thousands in repairs. Research from the Cool Roof Rating Council shows that white TPO membranes can reduce rooftop temperatures by up to 60 degrees, cutting cooling expenses by 20 percent or more.
Every project begins with a thorough moisture scan, substrate evaluation, and load-capacity review. You'll get a transparent scope of work, material certifications, and a project timeline that minimizes tenant disruption and maximizes uptime.
Flat Roof Challenges Unique to Tempe
Tempe sits in the Salt River Valley, where summer heat islands push surface temperatures above 160°F on black roofs. Ponding water from monsoon storms accelerates membrane degradation, and UV radiation breaks down substandard sealants in months rather than years. Commercial properties near Arizona State University and Tempe Town Lake face added stress from dust particulates and urban pollutants that clog drains and degrade coatings.
Flat roof systems require positive drainage, code-compliant scupper placement, and reinforced penetration flashings around HVAC curbs and skylights. The International Building Code mandates a minimum slope of one-quarter inch per foot to prevent standing water, yet many older Tempe buildings fall short. Studies indicate that standing water reduces membrane lifespan by up to 50 percent if left unaddressed. Every inspection includes a drainage analysis and recommendations for tapered insulation or crickets.
Thermal shock—rapid temperature swings from day to night—can crack rigid insulation and open seams in poorly installed membranes. Contact us today for Commercial Roofing in Tempe and safeguard your investment with a system designed for Arizona's extremes.
