What Types of Material Do We Use for Commercial Roofs?

Our services encompass the installation of white membranes, reflective coatings, and cool-hued shingles to enhance energy efficiency and elevate interior comfort throughout the year.

We offer comprehensive roof maintenance aimed at preventing leaks, extending system longevity, and improving performance through regular inspections, cleaning, and minor repairs. Our assessments, debris clearance, seam resealing, and drainage evaluations help property owners avoid costly disruptions, protect warranties, and maintain uninterrupted waterproofing for all commercial roofing systems.
Metal Roofing
Metal roofing boasts a remarkable lifespan of 40 to 60 years and can reflect as much as 70% of solar heat, establishing it as one of the most energy-efficient and sustainable choices for commercial applications. With outstanding wind resistance rated up to 140 mph, these roofs also contribute a contemporary, polished look that enhances the visual appeal of commercial buildings.
Flat and Low-Slope Roofing Systems
Flat and low-slope roofs are engineered for superior drainage and waterproof performance, minimizing leaks and water accumulation that can cause costly damage. They feature high-R-value insulation and seamless membranes, forming a strong barrier against the elements. Consequently, these roofs enhance building durability and ensure year-round energy efficiency, reducing heating and cooling costs while maintaining indoor comfort.
What Types of Material Do We Use for Commercial Roofs?
Ponding Water
Ponding water occurs when insufficient drainage or irregular insulation results in water gathering on flat or low-slope roofs, accelerating membrane wear and resulting in leaks. We tackle this problem by regrading the surface with tapered insulation, clearing any blockages from the drains, and applying waterproof coatings to guarantee proper runoff and avert future pooling.
Flashing Failure
Poorly installed flashing around vents, HVAC units, or roof edges can cause water intrusion and leaks, risking structural integrity and leading to costly repairs. We remove damaged flashing, clean the areas, and reseal or replace it with durable materials like premium metal or TPO-compatible options. We also reinforce seams for long-lasting waterproof protection, ensuring peace of mind against future leaks.
Damaged Roofing Membrane
Over time, roof membranes may encounter problems such as cracking, blistering, or puncturing due to influences like UV exposure, foot traffic, and temperature changes. Our expert team employs thorough patching, seam resealing, and infrared moisture scanning to identify vulnerabilities and reinforce a watertight barrier, all without needing a full replacement.
Storm or Tree Impact Damage
Intense winds, broken branches, and storm debris can result in punctures, tears in the membrane, and considerable roof damage. Our specialists conduct emergency assessments, remove debris, reinforce affected sections, and perform thorough membrane restoration or panel replacement to bring your roof back to its original condition.

Various factors, including roof accessibility, necessary tear-offs, and local regulations, can impact pricing.

How Long Does a Commercial Roof Replacement Take?
