Roof & Exterior

The roof is the single most important surface on your RV when it comes to long-term structural health. A roof that leaks does not just let in rain — it destroys the wood substructure, delaminating walls and floors over months or years in ways that turn a small repair into a $10,000 renovation. RV roofs come in several material types: rubber EPDM (the most common, a rolled membrane), TPO (thermoplastic polyolefin, common on newer coaches), fiberglass, and aluminum. Each has its own maintenance requirements, failure modes, and repair methods. Warning signs that your roof or exterior needs attention: soft spots when you walk the roof (indicates water has already penetrated the membrane and reached the wood decking below), visible cracking or crazing in the rubber membrane (especially around seams, vents, and air conditioner mounts), water stains on interior walls or ceiling that appear after rain, and exterior sidewall delamination where the outer skin bubbles or separates from the insulation behind it. When hiring a mobile technician for roof work, ask whether they specialize in your roof type. EPDM repair requires different materials and techniques than TPO or fiberglass. Ask about the products they use for sealant — Dicor, Eternabond, and Proflexrv are reputable brands, but application technique matters as much as product choice. A proper roof inspection includes cleaning, probing for soft spots, and resealing every penetration point: vents, AC units, antennas, and front and rear cap seams. Cost ranges: Annual roof resealing service runs $200 to $500 depending on coach length. Membrane patching for a damaged section averages $150 to $400. Full EPDM roof replacement on a typical travel trailer runs $1,500 to $4,000. Mobile roof technicians provide huge value because they can inspect and address issues while your rig is parked at home or at a campsite, before small sealant failures turn into expensive structural damage.
