OCRV Center repairs laminated fiberglass roof caps on RVs and fifth wheels in our Yorba Linda shop, from stress cracks and soft spots to delamination at the seams. Most fiberglass roof repairs run from about $750 to $9,000 depending on the area and any structure underneath.
A fiberglass roof is a structural laminate, gelcoat over fiberglass over a core, so a crack or a soft spot is not just cosmetic, it is the bond letting go. We grind the failed laminate back to sound material, rebuild it with matching fiberglass and resin, and refinish the surface so it carries load and sheds water again. All work is in-shop only at our Yorba Linda facility.
Fiberglass roof problems we repair
The common failures on a fiberglass cap are spider and stress cracks in the gelcoat, a soft or spongy area where the core has separated from the skin, and delamination along the front cap seam where the roof meets the front wall. Each one means water has found, or will find, a path into the laminate, so the repair has to restore the bond, not just hide the crack.
- Gelcoat stress and spider crack repair
- Soft spot and core separation rebuild
- Front cap and seam delamination repair
- Impact and puncture laminate restoration
- Color-matched gelcoat or refinish over the repair
How we rebuild a fiberglass roof in the shop
We map the failed area, often larger than the visible crack, then grind it back to sound laminate, rebuild it in layers of fiberglass mat and resin, and fair the surface flush. The repair is structural first and cosmetic second, so we let each layer cure properly before the next, which is only practical in a controlled shop.
Because a fiberglass roof is part of the coach structure, we check whether water has reached the core or the wood beneath the cap. If it has, that gets restored at the same time so the new laminate is not bonded over a wet or rotten substrate.
- Damaged area mapped beyond the visible crack
- Laminate rebuilt in fiberglass mat and resin layers
- Each layer cured properly in a controlled shop
- Core and substrate checked for trapped water and restored if needed
- Surface faired flush and refinished to match
Frequently asked questions
Is a crack in my fiberglass roof just cosmetic?+
Sometimes the crack is only in the gelcoat, but a stress crack is often a sign the laminate underneath is flexing or starting to separate. We inspect how deep it goes before quoting, because a surface fill over a structural problem will crack again. The honest repair restores the laminate, not just the gelcoat.
What causes a soft spot on a fiberglass RV roof?+
A soft or spongy area usually means the fiberglass skin has delaminated from the core, often after water got in through a seam or a penetration. We rebuild the laminate so the skin and core bond again, and we check the structure underneath for water damage at the same time.
Can you match the finish after a fiberglass roof repair?+
Yes. We fair the repair flush with the surrounding roof and refinish it with color-matched gelcoat or paint so the repaired area blends with the original cap rather than reading as a patch.
