Roof and panel cracks can develop from age, road vibration, sun exposure or impact damage, and the cause often determines whether it's a simple cosmetic fix or something more serious underneath.
Fine surface cracking is often cosmetic, but cracks that follow a fitting, corner or seam, or that keep returning after being patched, usually point to something happening underneath the surface.
If a crack keeps coming back or sits near a fitting or seam, it's worth getting it properly assessed rather than just patching the surface again.
Caravan exteriors go through a tougher life than most people realise. Constant sun exposure breaks down the surface layer over years of use, while the vibration and flex from regular travel puts repeated stress on panels, seams and the fittings bolted through them. Add in temperature swings between hot days and cooler nights, and the materials are expanding and contracting constantly, which puts ongoing strain on any joins or weak points.
Roofs cop a particularly tough run, being the most exposed surface to UV and the section most likely to have multiple penetrations for vents, hatches, aerials and roof-mounted accessories, each one a potential stress point.

A crack that looks similar to another from the outside can mean two completely different repairs depending on what's actually happening underneath.
Roof fittings like vents, hatches and aerial mounts are bolted or sealed through the panel, which makes that exact spot a concentration point for stress. Cracks that develop right at the edge of a fitting are often a sign that movement or flex is happening at that join, and simply filling the crack without addressing the seal or mounting point underneath can mean the same crack reappears, sometimes alongside a new water leak if the seal has also failed.
