RV Roof Repair and Resealing in Prescott

Roof failure is the single most expensive mistake an RV owner can make, and it starts as something as small as a cracked bead of sealant around a vent. Water finds that crack, gets under the membrane, and by the time it shows up as a stain on the ceiling, it has usually been sitting in the roof structure for weeks or longer. Catching it early is a $500 to $1,200 reseal. Catching it late is a $2,000-plus structural repair.

We inspect, dig out and replace failed sealant, and reseal vents, skylights, antennas, and seams on site, wherever the rig is parked.

What we repair on site

• Lap sealant (dicor and similar self-leveling sealants): dug out where it has cracked, shrunk, or pulled away, cleaned, and redone properly, not just caulked over the top of the old bead.
• Vent and skylight seals: the highest-failure points on any roof, resealed with the correct sealant for the roof material.
• Roof AC gaskets: a dried, cracked gasket under the AC shroud is a common, cheap leak source that looks like a much bigger problem.
• Seam and membrane inspection: for rubber (EPDM/TPO) and fiberglass roofs, checking for soft spots, delamination starting at the edges, and any place water has been sitting.
• Hail damage assessment: pitting, cracking, or punctures from a monsoon storm, documented with photos for your insurer as well as repaired.
• Wood-rot and soft-decking repair: when a leak has been running long enough to reach the roof’s wood substrate, it needs structural repair, not just a fresh bead of sealant on top.

Why roofs need attention on a different schedule here

Prescott’s roof problems come from two directions that both matter, unlike a purely desert climate. UV dries and shrinks sealant, the same as anywhere in Arizona: intense sun at elevation cracks a lap sealant bead over a few years regardless of temperature. Monsoon, officially June 15 through September 30, adds hail and heavy, wind-driven rain on top of the UV damage, and hail specifically pits and cracks rubber and gasket material in ways a dry climate without hail does not. Then winter adds a third factor most of the rest of Arizona does not have to think about: sealant and rubber gaskets stiffen in the cold, and if snow or ice sits in a roof valley after a storm, the freeze-thaw cycle can work a marginal seam open before spring.

The practical result is a roof that needs checking on two calendars: late spring, before monsoon starts, while any needed reseal can cure on dry days, and after any hailstorm that seemed severe enough to worry about, especially on a rig that has been parked in the open through it.

What it costs

Same rule as everything on our pricing page: we inspect and diagnose first, then you get a written number before any work starts.

What to check yourself first

If you can safely get on the roof (or send us a phone video if you cannot), a quick visual check before calling helps: run a hand along every seam and vent base feeling for cracked or missing sealant, look for any spot where the roof surface looks discolored or “wavy,” and check inside at ceiling corners and around vents for staining, which means water has already gotten in. Do not walk a roof you are not confident is structurally sound; a soft spot underfoot is itself the sign of a problem, and it is exactly the kind of thing worth a professional inspection rather than testing it with your weight.

Where we work

On site across Prescott, Prescott Valley, Chino Valley, Dewey-Humboldt, Williamson Valley, Paulden, and Mayer. If you are not sure whether what you are seeing is a roof leak or something else, the roof leak problem page walks through the checks, and the roof cost calculator turns your rig’s length and roof condition into a specific estimate.
