Inadequate surface preparation or improper adhesive application can compromise seam integrity, leading to water infiltration. Regular roof inspections help identify seam issues before they become major problems.
Limited Aesthetic Appeal (Black EPDM)
The standard black in color appearance of EPDM roofing may not suit all architectural preferences. While this dark surface helps reduce heating costs in colder climates by absorbing solar energy, it may increase cooling expenses in warmer regions. Although EPDM is available in white formulations, these options typically cost more and may have different performance characteristics.
Property owners seeking a distinctive visual appeal might find EPDM’s utilitarian appearance limiting compared to other roofing materials that offer varied colors and textures. However, the functional benefits often outweigh aesthetic considerations in commercial applications.
EPDM Roofing System Installation Methods
Professional installation of EPDM requires careful consideration of the specific type of installation best suited to each project. The ballasted system involves laying the membrane loose and securing it with gravel or concrete pavers. This approach works well for buildings with adequate structural capacity to support the additional weight.
Mechanically attached installations use fasteners and plates to secure the membrane at predetermined intervals. This method reduces overall system weight while providing a reliable attachment. The fully adhered approach bonds the entire membrane surface to the substrate using specially formulated adhesive, creating a continuous seal.
Accessories and tools required for proper installation include specialized rollers, cutting knives, cleaning solvents, and seaming equipment. Professional contractors possess the expertise to select appropriate installation methods based on building characteristics, local climate conditions, and performance requirements.
