Duro-Last roofing systems are designed to be virtually maintenance free. In order to protect your investment in flat roof repair or restoration, there are steps that you should take to ensure the longevity of the membrane system and maintain the warranty.
Regular inspections should be performed to prevent premature failures of the roofing membrane. Detecting minor problems before they become serious allows for quick repair without disruptions. Roofing inspections should be performed by a professional who is knowledgeable in Duro-Last membranes. These inspections should be completed twice each year in average climates.
One inspection should be performed in the early spring to make note of any potential problems that harsh winter weather may have caused. This also allows any repairs to be completed in a timely manner during reasonable weather conditions. The second yearly inspection should be completed in mid to late fall, before snow or ice can accumulate.
The fall inspection allows debris to be removed from the roof surface that could otherwise present a drainage problem. Additional inspections should be performed after any heavy storms, nearby fires or when the building has undergone construction work that involves the rooftop.
During the inspection of the Duro-Last system, notes should be made regarding any unusual wear patterns or deterioration. A record should be kept with notes about any areas with poor drainage or substantial debris accumulation. While Duro-Last does not exclude standing water under the membrane warranty, the problem should be resolved to prevent structural damage. If any ballast is used on the roof, loss or displacement of the ballast should be noted.
Areas that use sealants or caulks require careful inspection. Sealants are prone to peeling, cracking or splitting and repair work should be completed immediately, before water can begin to penetrate the area. Any sealants used for flat roof repair should be a Duro-Last product. This ensures the quality of the sealant and the compatibility with the membrane material. A white roof membrane should be washed with a non-abrasive, non-sudsing cleanser to help maintain the solar reflectivity.
Duro-Last flat roof repair membranes are prefabricated before installation. This eliminates up to 85 percent of the installation work and seaming that would otherwise be completed on the site. Seam work done on the roof top is completed with heat welding, which provides a stronger seal than glues or liquid products. With regular roof inspections, your Duro-Last flat roof repair should provide you with years of superior service.
