Roof Recover & Overlay Systems

Recovery systems typically last 20-30 years or more, depending on the materials used and maintenance. TPO, PVC, and metal systems often exceed 25 years, while modified bitumen systems average 15-20 years. With proper maintenance, recovery roofs perform identically to new construction installations.

Your existing roof warranty is likely expired or near expiration if you're considering recovery. The new recovery system comes with its own comprehensive manufacturer warranty (typically 10-20 years), replacing any previous coverage. We handle all warranty registration and documentation.

Yes, when properly designed and installed. Most building codes allow up to two roof layers. We ensure all recovery installations meet current code requirements including fire ratings, wind uplift, and insulation standards. All necessary permits are obtained before work begins.

Most commercial low-slope roofs are candidates for recovery including BUR, modified bitumen, single-ply membranes, and even some metal roofs. However, the existing roof must be structurally sound with dry insulation. We perform a thorough inspection to determine compatibility and make honest recommendations.

All penetrations (HVAC units, vents, drains, etc.) are properly flashed and sealed as part of the recovery installation. In many cases, this is an opportunity to upgrade outdated flashing systems and improve weatherproofing around vulnerable areas that may have been causing problems.

Recovery systems typically add 2-5 pounds per square foot depending on materials used. We perform structural calculations to ensure your building can support the additional weight. Most commercial buildings are designed with sufficient capacity for recovery systems, especially when insulation upgrades are included.

With increased insulation, most buildings see 20-30% reduction in HVAC costs. On a typical 20,000 sq ft building spending $15,000 annually on heating/cooling, you could save $3,000-$4,500 per year. The added insulation often pays for itself within 5-7 years while extending your roof's lifespan decades.

Yes, many recovery systems can be installed year-round. Self-adhering modified bitumen and mechanically-attached single-ply systems work in cold weather. Some systems like spray foam require warmer temperatures. We'll recommend the best system and timing for your climate and schedule requirements.
