Why Resealing Your RV Roof Is a Must – And the Product We Trust Most
Your RV is more than just a vehicle— for some, it’s your home on wheels. Whether you’re a weekend warrior or a full-time traveler, one of the most important maintenance tasks you can’t afford to skip is resealing your RV roof.
Why Resealing Is So Important
Over time, the sun’s UV rays, rain, wind, and debris all take a toll on your RV’s roof. The smallest of cracks or wear in the sealant can lead to costly water damage, mold, interior leaks, and major structural repairs. Resealing your roof periodically acts as your RV’s first line of defense, and is a small measure that offers enormous protection against damage.
We recommend inspecting your roof at least twice a year and resealing when you notice any cracking, peeling, or soft spots in the sealant. For most RVs, this means a reseal every 1–2 years, depending on climate and usage. Here in Arizona, an annual roof reseal may be beneficial.

Can I Do It Myself?
Yes! If you’re comfortable on your roof and have the right supplies, you can absolutely reseal your RV roof yourself. But it’s hot out there, and safety is always priority #1. If you’re not sure what products to use or if climbing up in this summer heat doesn’t sound appealing, that’s where we come in. Call us to schedule your annual roof reseal, or search for a Mobile RV Repair Company in your local area.
