Buying Guide

Adhesive chemistry matters

Choose tapes formulated for EPDM and roofing substrates to ensure long-term adhesion and chemical compatibility with drain pans and surrounding materials

Match tape width to the repair

Wider tapes (4–6 inches) cover larger cracks and seams faster, while 2-inch rolls work better for narrow seams and precise patches

Weather and UV resistance

Select weather-resistant, UV-stable tapes when sealing drain pans exposed to sunlight or outdoor conditions to avoid premature degradation

Surface prep improves performance

Clean, dry, and degrease the pan and surrounding surfaces before application to maximize peel strength and longevity

Evaluate value by roll length and durability

Compare roll length and proven adhesive performance—longer 50' rolls can offer better value for recurring maintenance, especially on larger roofs or fleets
