How to Repair a C Class RV Roof

RV roofs in general take a beating from the elements. However, the roofs of C-class RVs are somewhat more prone to wear and tear than those of other RVs, because of their curved or angled front sections that rest over the top of the driver's cab. Leaks in your RV roof can become a serious problem, and not just because they can ruin your camping trip. They can also do substantial damage to your RV, a very expensive piece of hardware. Patching leaks is fairly easy, but lasting repairs will require more effort.

Instructions

Difficulty: Moderate

Things You’ll Need:

Ladder
Broom
Mop
Roll(s) of Eternabond sealing tape
Crowbar or screwdriver
Hammer
Nails

Step 1

Climb on top of the RV with a ladder, and sweep all debris off the roof. Then clean the roof with a little water and a mop. Since you are fixing a leak, it is probably not a good idea to clean the roof simply by blasting it with a hose.

Step 2

Repair leaky roof seams or cracks by covering them with Eternabond roof-sealing tape. Peel off the clear plastic film from the adhesive side, and apply it over the seams 3 to 4 inches at a time. Stop and rub the tape surface so it sticks properly before continuing. This tape is supposed to be tougher and longer-lasting than caulk, and is much easier to use.

Step 3

Go inside the RV and check for interior roof damage wherever there is either water damage or water was seen penetrating. Use a crowbar or screwdriver to pry off the ceiling panel there, and examine the plywood for rot.

Step 4

Replace rotten plywood by cutting a replacement section of matching size from a section of marine plywood. Pry out the old plywood roof panel, put the new one in place, and nail it into the support struts.

Step 5

Put the ceiling panel back into place.
