Buying Guide

Match sealant to roof material

Choose products explicitly compatible with your roof (for example, EPDM-compatible tapes) to ensure adhesion and long-term performance

Pick the right width and length

Select tape width (2–4 inches) and roll length (typically 50 ft) based on gap size and total run to minimize seams and waste

Check UV and weather resistance

Use UV-stable, weatherproof formulations or tapes designed for outdoor RV exposure to prevent breakdown and reapplications

Consider ease of application

Tapes with strong adhesive backing and peel-and-stick formats simplify repairs compared with liquid sealants that require tooling and cure time

Evaluate cost per linear foot

Compare price against roll length — for example, $41–$58.50 for 50 ft rolls — to determine value for long runs or frequent repairs
