Buying Guide

Match coating to roof material

Choose primers or protectants specifically formulated for your roof type (rubber/EPDM, TPO, or silicone-ready) to ensure adhesion and longevity

Know coverage and application

Check manufacturer coverage per gallon and whether the product is spray-on, roll-on, or primer to estimate how much you need and the labor involved

Check compatibility with sealants

Confirm the coating or primer bonds to existing sealants and previous treatments to avoid peeling or chemical reactions

Prioritize UV and weather resistance

Look for formulations described as UV-resistant or protectant sprays designed to slow sun and weather damage for longer roof life

Consider prep and cure time

Factor in required surface prep (cleaning, priming) and cure time before travel to plan your maintenance schedule
