Buying Guide

Match tape width to the seam

Choose wider tapes (4–6 in) for roof seams and flashing, narrower options (1/8–2 in) for trim and seam work to avoid excess overlap and ensure proper coverage

Check material compatibility

Ensure the butyl formula bonds to your substrate—EPDM, metal, fiberglass, and common RV roof materials—since some tapes are formulated specifically for RV roofs or EPDM rubber

Prioritize UV and weather resistance

For outdoor roofing and RV applications choose tapes labeled UV-resistant or designed for roof sealing to maintain performance under sun and seasonal exposure

Consider peel-and-stick vs putty style

Peel-and-stick seam tapes offer easy long runs and uniform coverage, while putty-style butyl tape is more flexible for irregular shapes and detail work

Check roll length and thickness

Longer rolls reduce joins on big projects and thicker tapes provide better gap-filling; balance roll length and tape cross-section to minimize seams and ensure waterproofing
