Material Selection and Preparation

We start by assessing your building’s structure and environmental factors to choose the ideal PVC roofing membrane. This includes selecting a membrane thickness and formulation designed for resistance to weather, chemicals, and fire.



Before installation, we conduct a thorough inspection of the roof deck to confirm it is clean, dry, and structurally sound. Precise measurements are taken to minimize waste and ensure proper fit. We also prepare necessary insulation materials to enhance energy efficiency and roof longevity.

Mechanically Fastened and Fully Adhered Methods

We use two primary attachment methods depending on your roof’s requirements: mechanically fastened or fully adhered systems.



In mechanically fastened installations, the PVC membrane is secured with plates and fasteners, providing robust resistance to wind uplift. This method allows for quicker installation on large commercial flat roofs.

For fully adhered roofing, we apply an adhesive to bond the membrane directly to the insulation or deck. This creates a smooth surface with enhanced waterproofing and resistance to membrane movement under thermal expansion.

Heat-Welded Seam Technology

To ensure the roof maintains its waterproof integrity, we rely on heat-welded seam technology. Using hot air welders, we fuse overlapping PVC membrane edges, creating a continuous, watertight bond.



This method prevents leaks better than traditional adhesives or tapes, offering superior strength and durability. Our trained technicians carefully inspect every seam for uniformity and coverage, which is crucial for long-term performance.

Durability and Longevity

Our PVC roofing installations are designed to last for decades with minimal maintenance. Polyvinyl chloride membranes resist deterioration from UV exposure, temperature fluctuations, and harsh weather conditions common in Joliet, IL.



Welded seams on PVC roofs create a bond stronger than the material itself, preventing leaks and water damage. This durability supports building protection against heavy snow, rain, and wind without sacrificing flexibility, reducing the risk of cracks or punctures over time.

Exceptional Chemical Resistance

We recognize that many commercial buildings face exposure to oils, grease, acids, and other industrial chemicals. PVC roofing systems stand out for their excellent chemical resistance compared to other roofing materials.



This property makes PVC an ideal choice for restaurants, manufacturing facilities, and other environments where chemical spills or fumes might occur. The polyvinyl chloride membrane withstands these substances without degrading, reducing maintenance costs and preventing premature roof failure.

Energy Efficiency and Reflectivity

Our PVC roofing membranes are highly reflective and energy-efficient, directly impacting cooling costs in commercial buildings. The white surface reflects sunlight, reducing the amount of heat absorbed by the building.



This reflective property helps keep interior temperatures lower during hot months, lessening the reliance on air conditioning systems. As a result, businesses can achieve measurable savings on energy bills while contributing to a reduced environmental footprint.
