Full RV Roof Replacement in Yorba Linda

Walk the roof, carefully. A sound roof feels solid underfoot across its whole area. A compromised roof gives, flexes or feels spongy, particularly near penetrations and at the front third where the most water has run.

Then moisture readings from inside at the ceiling, and a visual check of the ceiling panel for staining. Where the decking has gone the ceiling almost always shows it, even faintly.

• Spongy or flexing areas underfoot, worst near penetrations
• Ceiling staining or panel sag from below
• Elevated moisture readings at the ceiling and upper sidewall
• Fasteners that will no longer hold in the decking
• Visible substrate delamination at any opened penetration
• Rafter or truss damage where water has stood a long time

Everything comes off the roof. Air conditioner, vents, fans, antennas, solar, ladder, front and rear cap trim, and both sidewall awning and roof rails. All of it is catalogued so it goes back in the correct location with correct new sealing rather than reused sealant.

Then the old membrane and decking come off in sections. Rafters are inspected and repaired where water has reached them. New decking goes down, then new membrane, then every penetration is reinstalled with new butyl and new sealant, then trim and rails.

That is why it is 30 to 120 hours. Most of the labor is removal, cataloguing and reinstallation rather than the membrane itself.

Frequently yes, and the arithmetic is straightforward. A roof is the component whose failure destroys everything below it, so replacing it resets the clock on the whole vehicle rather than on one system.

Where it is not worth it is on a coach that already has extensive sidewall delamination and floor damage. At that point you are looking at $4,500 to $22,000 for the roof plus $1,500 to $18,000 for walls plus $1,200 to $12,000 for floor, and we will put those numbers next to the vehicle value and let you decide rather than selling you the job.
