Modified Bitumen Roofing FAQs
How long does a modified bitumen roof typically last on commercial buildings?
Modified bitumen roofing systems generally provide 20 to 30 years of reliable service when properly installed and maintained according to manufacturer guidelines and industry standards. Actual lifespan depends on factors such as installation quality, local climate, roof slope, maintenance frequency, and the specific materials used. Regular inspections and prompt repairs help your modified bitumen roof reach or even exceed its expected service life, protecting your long-term investment.
What is the difference between APP and SBS modified bitumen roofing?
APP (Atactic Polypropylene) modified bitumen uses polymers that offer excellent heat resistance and aging characteristics, and is typically installed with torch-down methods for superior adhesion and performance. SBS (Styrene-Butadiene-Styrene) modified bitumen provides exceptional flexibility and cold-weather performance, and can be installed using either torch or cold-adhesive methods. Both systems deliver strong waterproofing and durability, with the choice depending on your building’s requirements, climate considerations, and preferred installation method.
Can modified bitumen roofing be installed over my existing commercial roof?
Yes, modified bitumen systems can often be installed as an overlay if the existing roof is structurally sound, dry, and meets overlay conditions. Our team evaluates whether your current roof qualifies for an overlay or requires a full tear-off to ensure optimal performance. Factors include roof condition, number of existing layers, building code requirements, and whether overlay installation would impact the longevity or effectiveness of the new roof.
How soon can my business resume normal operations after modified bitumen roof installation?
Most modified bitumen projects are completed with minimal disruption, allowing normal operations to continue in most areas of your building. Installations typically take several days to two weeks, depending on roof size, complexity, and weather conditions. Our crews work efficiently to minimize noise, odors, and access restrictions, keeping your employees, tenants, and customers safe and comfortable throughout the project.
What maintenance does a modified bitumen roof require to maximize its lifespan?
To extend service life, modified bitumen roofs require semi-annual inspections, regular debris removal, and prompt repairs for any damaged areas. Seasonal maintenance includes clearing drains and gutters, removing debris that could puncture the membrane, and scheduling professional inspections after severe weather. This proactive approach helps prevent minor issues from becoming major problems, ensuring your roof performs at its best for decades.
