RV roof clean and reseal DIY

A DIY RV roof replacement is certainly possible, and will help you save lots of money since you will only need to buy the materials.

The following are all of the steps to follow when replacing your RVs roof:

  • Remove any fixtures, such as vents, antennas, or air conditioning units. Remove the awning as well.
  • Use a high-quality stainless steel putty knife to scrape away the old sealant around the removed fixtures.
  • Remove the existing roof membrane. For RVs rubber roofs such as TPO or EPDM, you will need to peel back the roofing material until you can see the plywood structure beneath. Aluminum roofs require you to unscrew the old panels to remove them, and you will need a dye grinder to remove the fiberglass matting that covers these types of roofs.
  • Check the plywood beneath the roof membrane for damage. If you notice areas where the wood is rotted or bowing, it has water damage and should be replaced. Clean the rest of the plywood with mineral spirits to treat it to prevent mold and mildew from growing.
  • Install seam tape in places where the plywood meets and along the edge of the campers roof where it meets the side of your camper. This will help maintain a good seal and reinforce any weak areas.
  • After your roof is replaced, the final step is to reinstall your RVs roof fixtures and seal them with caulking to prevent any leaks in the new roof.

    Pitched Or Sloped Roofs

    Most pitched roofs are asphalt shingle or tile where complete coatings are not recommended. However, there are some exceptions and considerations when dealing with a pitched roof.

    • Metal: such as in residential settings, can use an elastomeric coating for corrosion resistance or just to extend the life of the roof. You’ll usually pay an additional $1.00-$2.00 per square foot since the coatings must be applied in multiple thin layers.
    • Asphalt Roll: For small leaks and tears, elastomeric bitumen sealants run between $15 to $20 per gallon or about $6 to $10 per 10-ounce tube. Use repair fabric in conjunction with these sealants. Fabrics will cost about $10 for a 25-square foot roll.
    • Asphalt Shingle: Only use bitumen or elastomeric sealants around flashing, vents and skylights. Using complete coatings on asphalt shingles is a short-term fix and may actually do more harm than good. Repairing or replacing your damaged asphalt shingles is the long-term solution. Replace any underlayment and damaged roof sheathing as well. Considering that installing a new asphalt roof costs an average of $3,700 and a new tile roof costs an average of $11,500, the price of repairing asphalt shingles as a solution is well worth the investment.
