Identifying Soft Spots in Your RV Roof

Soft spots in your RV roof can be a cause for concern, as they often indicate underlying damage or structural issues. To identify these areas, you’ll want to start with a visual inspection of your RV’s roof. Look for any areas that appear discoloured, warped, or appear to sag slightly when pressure is applied. 

When conducting your inspection, pay close attention to seams, joints, and areas around vents or other roof penetrations. These are common trouble spots for softening due to potential water intrusion. Soft spots can often be hidden beneath the RV’s roof membrane, making them difficult to spot with the naked eye. 

Essential Tools and Materials for RV Roof Repairs

You’ll need a utility knife for cutting away the damaged section, as well as a putty knife or scraper for removing old sealant. 

In addition to tools, you’ll require materials such as replacement roofing material (e.g., plywood), sealant (typically a self-levelling lap sealant or butyl tape), and screws or fasteners for securing the new material. Safety gear, including gloves and safety glasses, is also a must.

When you’ve identified a soft spot in your RV roof and gathered the necessary tools and materials, it’s time to replace the damaged roofing materials.

In addition to sealing the immediate repair area, consider inspecting the entire RV roof for any other areas that may need attention. Even if you don’t see visible damage, proactive sealing can prevent future issues from developing.
