Understanding the Cost of RV Roof Repair for Rotted Wood: Fast-Track Guide to RV Roof Repair Costs and Tips

Repairing the roof of your RV, especially when dealing with rotted wood, involves several factors that impact the overall cost. Rotted wood in an RV roof usually results from prolonged water intrusion, poor maintenance, or aging sealants. The expense is influenced by the extent of the damage, the materials used, labor charges, and whether you opt for professional repair or DIY solutions.

Typical costs for RV roof repair involving rotted wood range from $500 to $3,500. A straightforward patch job for a small affected area might start around $500 if you only need to replace localized plywood and reseal with a membrane. More extensive repairs, involving full roof panel replacement, can climb above $3,000, particularly for larger motorhomes using high-quality materials like TPO, EPDM, or fiberglass. Labor rates average $60–$120 per hour, and professional servicing ensures the new wood is properly treated for future water resistance.

If you have experience with tools, you can save on labor by handling some aspects yourself. DIY repair may involve removing outer roofing material, cutting away rotted sections, installing new plywood, sealing seams, and reinstalling the roof membrane—expect material costs to range from $300 to $1,200 depending on the size and type of your RV. However, improper repair can lead to further water damage and costly structural issues.

As a designer, I’d always recommend assessing not just the immediate area but adjacent sections for hidden moisture or damage—sometimes rot isn’t visible until you start removing layers, and restoring the roof layout with proper ventilation and waterproofing is key. For planning and visualizing such extensive repairs, a 3D floor planner can help you map the scope of work and materials, especially if you want to modernize the look or improve durability during restoration.

Tips 1:

If you notice sagging roof sections, soft spots, or visible discoloration inside your RV, inspect all roof seams and penetrations thoroughly. Prompt intervention can prevent major repairs by identifying leaks early. Investing in high-grade sealants and modern roof membranes will pay off in durability and low maintenance over time.
