RV roof sealants and coatings create waterproof barriers that protect your RV from leaks and extend roof life. Self-leveling sealants fill gaps around vents, antennas, and penetrations; lap sealants bond to vertical and angled surfaces; and full roof coatings protect the entire membrane from UV damage and weathering. Regular sealing maintenance is the single most important thing you can do to prevent costly water damage.

What to Know Before You Buy

• Match the sealant to your roof type—EPDM rubber, TPO, fiberglass, and aluminum roofs need compatible products.
• Self-leveling sealant works on horizontal surfaces; lap sealant (non-sag) is needed for vertical or angled applications.
• Full roof coatings require thorough cleaning and prep; they're not patch products but complete surface treatments.
• Dicor is the dominant brand for rubber roof sealants; other manufacturers offer compatible alternatives.
