PVC Roofing and Repairs

PVC roofing is a proven choice for flat and low slope buildings. It delivers strong seams, bright reflectivity, and dependable performance. Many owners choose PVC for its resistance to heat, sun, and rooftop activity. Hardesty Roofing installs and repairs PVC systems across Central and Eastern Virginia. Our team serves Richmond, Charlottesville, the Tri Cities, Northern Neck, and Tidewater.

What PVC Roofing Is

Polyvinyl chloride roofing is a single-ply membrane reinforced with a fabric scrim. Sheets are joined by hot-air welding to form watertight seams. The surface is often white, reflecting sunlight and reducing heat gain. You can also select gray or tan colors if the design requires. Manufacturers offer several thicknesses to match performance needs.

Why Many Owners Choose PVC Roofing

Energy performance is a major advantage. The reflective surface helps lower cooling loads and utility costs. Chemical resistance is another strength for restaurants and labs. Grease and many chemicals do not degrade PVC like other materials do. Fire resistance is typically strong and well tested. Seams are heat welded for consistent strength and durability. Maintenance needs are predictable with regular inspections.

Considerations and Drawbacks

Upfront costs can be higher than they are for some single-ply options. Skilled welding is required for quality seams and details. Older membranes can lose flexibility as plasticizers migrate. Cold temperatures may expose brittleness in aging surfaces. Heavy foot traffic can still cause punctures without walk pads. Incompatible products can harm the membrane if used incorrectly. Asphalt contact and certain solvents should be avoided.

Common Issues with PVC Roofing

Seam failure sometimes appears after years of movement. Contamination during welding can also weaken a seam. Punctures and cuts occur near equipment and service paths. Flashings at penetrations may crack or pull back with age. Perimeter shrinkage can stress terminations and copings. Ponding water reveals low areas and strains roof details. Chalking or surface wear may reduce reflectivity over time.

How We Diagnose PVC Roofing Problems

Accurate diagnosis guides cost effective repairs. Our technicians inspect the field membrane and critical details. Moisture scanning helps locate hidden wet insulation. Cores confirm membrane thickness and system build. Drains and scuppers are checked for flow and debris. We also review traffic patterns and equipment placement. Findings are documented with photos and a clear plan.

Repairs That Restore Performance

Hot air re-welding corrects many seam issues. Cover strips may reinforce long seams after re-welding. Compatible PVC patches resolve punctures and cuts. Prefabricated boots replace failing pipe flashings quickly. Termination bars and new sealants secure stressed perimeters. Walk pads protect service routes and reduce future damage. Tapered insulation improves drainage where ponding persists.

Addressing Chemical and Grease Exposure

Grease laden exhaust shortens the life of many roofs. PVC tolerates this environment far better than most alternatives. Grease guards and sacrificial sheets add extra protection. Regular cleaning prevents buildup that can trap heat and dirt. Our team inspects fans, curbs, and adjacent seams closely. Corrective actions are prioritized to prevent recurring leaks.

When Repairs Are Not Enough

Every roof reaches a point where patching becomes less effective. Widespread brittleness signals advanced aging. Multiple seam failures across large areas suggest system fatigue. Saturated insulation will also drive interior issues and odors. At that stage, restoration or replacement becomes the better plan. We explain options with realistic service life expectations.

Restoration and Replacement Paths

Some PVC roofs accept compatible restorative coatings. Coatings can refresh reflectivity and slow surface wear. Manufacturer guidance is essential to ensure compatibility. Recovery assemblies may allow a new membrane to be placed over a dry deck. Tapered insulation can be added to remove chronic low spots. A full tear off is chosen when moisture is widespread. Code needs and energy goals inform the final design.

How PVC Compares to Other Systems

TPO also delivers reflectivity at attractive costs. EPDM offers strong flexibility in many climates. BUR provides multi-ply redundancy and weight for traffic. Modified bitumen combines asphalt layers with modern modifiers. PVC stands out where chemicals and grease are present. The best system depends on use, access, and budget.

Maintenance That Protects Your Investment

Routine care prevents small issues from becoming bigger problems. Seasonal inspections catch seam and flashing concerns early. Drains and scuppers should remain clean at all times. Debris removal keeps surfaces bright and reflective. Sealants at terminations deserve regular attention. Walk pads should be added where technicians travel. Records of repairs help track patterns and helps in planning ahead.

Pros and Cons Summary

PVC offers excellent energy savings and chemical resistance. Fire performance and welded seams add confidence. Maintenance is straightforward with trained service teams. Initial costs can exceed those of some market alternatives. Aging membranes may lose flexibility and chalk. Foot traffic protection remains important for long life. Correct detailing and compatible products are essential.

Safety and Quality Considerations

Hot air welding requires consistent temperature and technique. Clean surfaces are necessary for strong welds. The weather can affect on-site welding windows. Experienced installers adjust methods to conditions. Manufacturer training improves outcomes and warranties. Hardesty Roofing invests in training and quality control.
