A common issue affecting recreational vehicles involves a downward deflection of the roof membrane in the area supporting the air conditioning unit. This deformation, often visually noticeable, can compromise the structural integrity of the roof and potentially lead to water intrusion. As an example, a visible dip in the roof’s surface directly beneath the air conditioner, coupled with internal ceiling stains, may indicate this problem.
Addressing this structural weakness is critical for maintaining the RV’s weather resistance and preventing more extensive damage. Ignoring the problem can lead to costly repairs, including roof replacement and interior remediation due to moisture. Historically, factors such as inadequate roof support during manufacturing, aging materials, and prolonged exposure to environmental stressors have contributed to the prevalence of this issue. The integrity of the roof directly influences the resale value of the RV as well.
