RV Roof Inspection & Repair Manual

RV roofs fail differently than residential roofs — and they're inspected, diagnosed, and repaired differently too.

This manual is written specifically for RV and trailer owners: travel trailers, fifth wheels, Class A and C motorhomes, and truck campers. It covers the four main RV roof substrates (EPDM rubber, TPO, fibreglass, and aluminium), explains which sealant products are compatible with which substrate, and walks through the seasonal maintenance protocol that RV technicians use to keep roofs watertight between campground seasons.

Includes a full Dicor product selection and application guide — which Dicor products are self-leveling versus non-sag, where each is used, and how to apply them correctly to vent flanges, AC units, and seam joints.

Also covers when to walk away and pay a dealer — the signs of delamination, structural water damage, and substrate failure that are beyond DIY scope. Knowing that boundary is as useful as knowing the repair techniques.
