Summer road trips are what the RV life is all about. But different destinations put different stresses on your roof — from the blazing UV of the desert Southwest to the salt air of coastal routes and the hail-prone skies of the Great Plains. Here’s our guide to the top summer 2026 destinations, with roof-specific advice for each region.
1. Glacier National Park, Montana
Roof challenge: UV at altitude + afternoon hailstorms
Montana’s stunning scenery comes with rapid afternoon weather changes. At 5,000+ feet elevation, UV intensity is significantly higher than at sea level, accelerating surface oxidation on EPDM roofs. And afternoon convective storms can drop golf-ball-sized hail with little warning. If your roof hasn’t been inspected recently, review our pre-trip leak detection checklist before heading north.
2. Arches National Park, Utah
Roof challenge: Extreme heat expansion
Summer temperatures in Moab regularly exceed 105°F, and roof surface temps can hit 175°F. EPDM and TPO expand significantly in this heat, stressing seams and sealant. If you’re planning multiple weeks in the Southwest, a professional inspection — or better yet, a polyurea coating — is a worthwhile investment before you go. See our coating comparison guide for how different materials perform in extreme heat.
3. Outer Banks, North Carolina
Roof challenge: Salt air corrosion + humidity
Salt-laden coastal air is brutal on any exposed metal — fasteners, vent hardware, AC units, and antenna mounts. Ensure all penetration sealants are salt-air rated and check for any rust streaking around metal fixtures that might indicate moisture entry. Our maintenance guide covers coastal inspection protocols specifically.
4. Yellowstone National Park, Wyoming
Roof challenge: Rapid temperature swings
Yellowstone can see 50°F temperature swings in a single day — warm afternoons and near-freezing nights even in July. These thermal cycles are particularly hard on EPDM seams, which expand and contract with each cycle. If you’ve noticed any seam movement in the past, get it addressed before a Yellowstone trip.
5. Olympic Peninsula, Washington
Roof challenge: Extended rain + moss/algae growth
The Pacific Northwest’s legendary rainfall means your roof stays wet for extended periods. This promotes biological growth (moss, algae, lichen) that can root into and degrade EPDM membranes over time. Use an algae-inhibiting roof cleaner before and after a Pacific Northwest trip.
6–10: More Great Summer Destinations
Rounding out our list: the Florida Keys (salt and humidity), Colorado Rockies (altitude UV and afternoon lightning), Lake Superior Loop (wet conditions and temperature extremes), Joshua Tree (extreme desert heat), and the Blue Ridge Parkway (moderate climate, low stress — a great shakedown route for a newly coated or recently serviced RV).
Before Any Road Trip: The Essential Roof Check
No matter where you’re headed, run through our summer maintenance checklist before any trip over 500 miles. Pay particular attention to seams and penetration sealants — these are the two most common failure points. And if you’ve been putting off a professional inspection or coating, this summer is the time. Find a certified applicator near your home or near your destination — many members have their rig coated during an extended destination stay rather than driving home first.
