Quality Services,
Commercial roofs are investments that should perform reliably in every season, and precision installation is the difference between a strong system and future problems. At CVC Roofing, we serve Greenwood, IN businesses that need long-lasting and energy-efficient roofing, and as a Duro-Last installer we bring factory-trained skills and systems built for performance. When you call us at 317 557 0888, you reach a local team committed to correct installation, code compliance, and solutions that hold up in real Indiana weather.
We work with Duro-Last because it arrives custom fabricated, which cuts down waste and installation errors. Our role as certified installers is to follow the correct steps so your membrane fits, seals, and performs, and our crew brings experience that ensures every seam, every penetration, and every edge detail receives attention. Proper process matters just as much as material quality.
Key Information from a Duro-Last Installer
Inspection and Assessment
Every project begins with a full roof evaluation. We do not place a membrane over unknown issues. Before any Duro-Last installation, we check insulation condition, fasteners, deck stability, drainage design, and surface preparation needs. In Indiana, freeze/thaw cycles and seasonal expansion take a toll, so we verify the substrate can support the system.
We also take notes on rooftop units, vents, curbs, drains, and access points. That helps us plan fabrication and installation, so work is efficient and disruption to your business is minimal. A reliable roof starts with a clear plan, and we communicate findings, so you understand the path forward.
Custom Fabrication That Improves Installation
Duro-Last membranes are cut and welded at the factory based on your building’s measurements. That means fewer seams on site and less room for error. We handle precise measurements, details, and accessory lists, and the manufacturer fabricates panels that arrive ready for placement.
This approach eliminates much of the on-roof welding that other single ply systems require. With fewer field seams, performance improves, and long-term leak risk drops. Our role is to measure accurately and prepare properly so everything fits correctly when material arrives.
Surface Preparation and Insulation
A solid foundation is essential. We clear the roof surface, repair substrate issues, address wet insulation if present, and prepare the deck. We also install insulation or cover boards when needed to support long term durability and energy performance. Indiana buildings need thermal resistance in winter and heat reflection in summer, so our material layout supports both.
- We secure insulation to reduce movement
- We prepare edges, parapets, and penetrations
- We maintain drainage slope for water flow
This foundation ensures the membrane adheres or secures evenly and performs over time.
Membrane Placement and Fastening
Once prepared, we lay the custom panels, position them to avoid stress points, and secure them using mechanical fastening or adhered systems based on building needs. Seams arrive mostly welded, so we lock edges, flash penetrations, and heat weld remaining seams with precision equipment.
We also install prefabricated flashings, boots, and drains that come from Duro-Last, and we verify fit and seal around HVAC units, skylights, and other structures. Consistent fastening and seam quality remove weak points that cause trouble in extreme weather.
Quality Control and Walkthrough
After installation, we inspect every seam and flashing point. The manufacturer may also inspect it depending on warranty level. We test drainage, confirm fastening patterns, and address any detail that needs adjustment before we close the project. When we finish, we review maintenance steps, schedule future inspections, and answer operational questions.
Our goal is to provide a roof that protects your building for decades and a client who understands the system and feels confident in the work.
Expert Duro-Last Installer
A Duro-Last system is only as strong as the crew installing it. Certification means we follow required steps, use approved accessories, and complete training on the correct methods. That protects your warranty and ensures the roof performs as designed. Many commercial roofs fail not from material wear but from shortcuts and overlooked details. We treat every project with long term function in mind.
