Short answer

An RV roof reseal can be a low-cost DIY job or a several-hundred-dollar service appointment. The biggest drivers are roof length, prep time, old sealant condition, and whether a technician must travel to you.

Why length matters

Longer RVs have more edge seam footage and usually more roof penetrations. Air conditioners, vents, antennas, and skylights add prep time. A 20 foot trailer and a 38 foot fifth wheel are not the same job.

What the calculator includes

The calculator estimates seam footage, material allowance, labor hours, and service mode. It does not include rotten decking, membrane replacement, or emergency leak mitigation.

FAQ

Is resealing the same as roof replacement?

No. Resealing maintains seams and penetrations. Roof replacement means removing and replacing the membrane system.

How often should I inspect roof sealant?

Inspect at least seasonally and after severe weather or tree contact.
