When a certified applicator from our network arrives at your rig, they don’t just look at the top of the roof and start spraying. A professional assessment covers 47 distinct checkpoints — and we’re sharing that complete list here so you can conduct your own thorough inspection between professional visits.
This checklist was developed in collaboration with our senior certified applicators and builds on the foundations in our Roof Inspection Report guide and maintenance calendar.
Before You Go on the Roof: Interior Inspection (Points 1–12)
- Check all interior ceiling panels for discoloration, staining, or soft spots
- Run your hand along the ceiling fabric/panel seams — any separation indicates moisture
- Check above all window cornices — these are secondary water entry points
- Inspect ceiling in slideout areas specifically — slideout roofs are highest-risk zones
- Open all overhead storage compartments and inspect the ceiling above them
- Check bathroom ceiling around any roof vents
- Look for any musty odor — active mold in ceiling cavities has a distinctive smell
- Check the area directly above the refrigerator — the exhaust vent is a frequent leak point
- Examine all light fixtures for water infiltration marks
- Check the front cap area interior — front cap seams are high-failure zones on many rigs
- Document any findings with photos from directly below, showing context
- Use a moisture meter on any suspected areas before going outside
Roof Surface Assessment (Points 13–30)
- Walk the roof perimeter and check the drip edge/edge trim condition
- Inspect front cap seam — full width — for any cracks or separation in the sealant
- Check all lap sealant for cracking, hardening, or pulling away from the surface
- Inspect all seams for any separation or bubbling
- Assess the overall surface for chalking (white powder) — sign of UV degradation
- Look for any discoloration or dark spots that may indicate moisture retention
- Check for ponding areas — low spots where water pools
- Inspect the area around the AC unit(s) — most common failure point
- Check AC unit mounting bolts for tightness
- Inspect AC unit gasket condition — compress with your thumb; it should be soft and pliable
- Check all roof vents for cracks in the plastic dome or lid
- Inspect vent mounting flanges — ensure screws are tight and sealant is intact
- Check all antenna bases and their boot seals
- Inspect around any solar panel mounting hardware — common leak initiation point (see our solar panel guide)
- Check satellite dish mount base if present
- Inspect all skylight frames and gaskets
- Examine any roof-mounted speakers, lights, or accessories
- Do a full-hand sweep of the roof surface looking for any soft spots
Slideout Roof Assessment (Points 31–38)
- Inspect the slideout roof surface condition (often different material than main roof)
- Check the wiper seal condition — it should be pliable and making firm contact with the main roof
- Look for wear grooves in the main roof surface where the slideout wipes
- Check the drip cap over the slideout opening
- Inspect the front corners of the slideout where two seals meet — highest failure risk
- Check for any gaps between the slideout frame and the main roof surface when extended
- Examine the side seams of the slideout roof
- Document slideout roof condition with the room both extended and retracted
Rear and Side Transitions (Points 39–44)
- Check rear cap seam across the full width
- Inspect side roof-to-sidewall transition trim — full length both sides
- Check all ladder mounting points if present
- Inspect any roof rack or luggage carrier mounts
- Check awning mounting hardware penetrations if awnings are roof-mounted
- Examine any roof-level storage pod or add-on unit mounting points
Substrate Assessment (Points 45–47)
- If coating removal is possible, check substrate condition at a test area
- Confirm substrate type (plywood, OSB, foam board, composite) — affects coating selection
- Check for any delamination of the roof substrate from the frame — can be felt as a spongy “give” when pressing firmly
After Your Inspection
Any issues found should be prioritized by severity: active leaks and soft spots are immediate action items. Cracking sealant is urgent. Minor discoloration or surface chalking can be scheduled.
If you find anything concerning, don’t delay. Connect with a certified applicator for a professional assessment. Our applicators provide free evaluations for community members on their first consultation.
