Every summer, our community tests dozens of products — roof coatings, sealants, cleaning compounds, and UV treatments — in real-world conditions. We compile the feedback from our active member network and share the unfiltered results. Here’s what the community is saying about products tested this season.

Products Members Are Raving About

1. ArmorThane Polyurea — The Network’s Gold Standard

Year after year, this comes out at the top of member reviews in our testimonials section. Not a DIY product — application requires professional equipment — but the results are consistently rated exceptional. Members report zero issues through 5+ years of full-time use. Our certified applicators use this product exclusively.

2. Dicor Self-Leveling Lap Sealant

For maintenance sealing (not a replacement for coating, but excellent for its intended purpose), Dicor remains the most reliable product on the market. Members recommend the lap sealant specifically for EPDM and TPO — not for silicone or fiberglass applications where different chemistry is required. It flows well, adheres properly, and the 10-year-old tubes members find in their parts bins often still work fine.

3. Camco Roof Cleaner — Value Champion

At roughly $15/quart, Camco’s rubber roof cleaner is consistently rated the best value for regular maintenance cleaning. Safe for EPDM, effective on mold and algae, and gentle enough for coated roofs (confirm with your applicator). Available at most Walmart, Camping World, and Amazon.

4. 303 Aerospace Protectant for Rubber Roofs

After cleaning, this UV-blocking treatment conditions aging EPDM membranes and significantly slows oxidation. Members in the Southwest treat their roofs twice yearly and report noticeably slower degradation. Not a coating — it’s a conditioning treatment that helps maintain EPDM until you’re ready for a full coating.

5. EternaBond RoofSeal Tape — Emergency Fix That Actually Works

When you have a sudden leak 300 miles from the nearest service center, EternaBond tape is the emergency repair that will hold until you can get to a proper fix. Members emphasize this is temporary — 3–6 months maximum — but it genuinely works when you need to stop water fast.

Products To Avoid This Season

Members in our forum specifically flagged two products with repeated failure reports: a generic “elastomeric roof coating” sold at a major home improvement chain (not RV-specific, degrades rubber membranes) and a budget lap sealant brand sold at a discount RV parts retailer (members report failure within 60 days of application in hot climates). We’re not naming brands here, but check the forums for specific threads.
