Mike Thompson's RV Service & Parts
Fountain Valley RV shop with factory-trained techs, 4.7 stars across 145 Google reviews, strong on communication and warranty work.
Fountain Valley sits close enough to the coast that marine air and sun take turns working on your roof, and both leave marks. Four roof shops serve the city, plus five more nearby, averaging 4.6 across the group. Two of them will handle warranty claims, which matters if your rig is still covered. One is mobile, so you can skip the drive if the leak is small and the rig is level.

Mike Thompson's RV Service & Parts on the list carries the most reviews at 145 with a 4.7 rating, and it handles roof work alongside A/C and awnings, plus body, chassis and parts. That range helps when a leak turns out to have soaked a ceiling panel or shorted something electrical. South Coast RV Repair also rates 4.7 and does mobile calls along with roof, A/C and awning work, so one visit can cover a reseal and a sagging awning arm. Orange Coast Auto Body/RV takes roof jobs and works with insurance and warranties, useful if a tree branch or a low clearance bar did the damage rather than age. Ask whether the shop wants the rig dry before it arrives. Sealant will not bond to a wet roof.
Roof work fills up fast once the first storm shows up, and Southern California owners tend to wait until water is dripping on the dinette. Call in late summer or early fall if you can. A shop that has to dry out a soaked ceiling will charge more and keep the rig longer than one that just scrapes and reseals. Ask a straight question when you call: does the roof get inspected before anyone quotes a price? Lap sealant around vents and skylights fails first, and a shop that walks the roof will find the soft spots a photo misses. Also ask whether the part, whether it is a vent lid or a fan, is on the shelf or on order. A backordered skylight can hold your rig for a week.
The single mobile option here suits a cracked vent cover, a reseal along one seam, or a leak you can trace to a specific fitting. It saves you a drive and a drop-off. It does not suit a full membrane replacement, a rotted deck, or anything where the tech needs a lift and a dry bay. If you are unsure, call the mobile tech first and describe what you see. Good ones will tell you when the job belongs in a shop. South Coast covers both sides, so the answer may simply be a shop appointment. For anything touching the frame or a collision, the body shops on the list are the better call.
Four shops are based in Fountain Valley, and five more are nearby, giving you nine options within reasonable driving distance. Two of them do warranty work, which helps if your roof or the damage is still covered.
The group averages 4.6. Mike Thompson's RV Service & Parts holds a 4.7 across 145 reviews, the largest sample on the list. South Coast RV Repair also sits at 4.7, and Orange Coast Auto Body/RV is at 4.0 with 31 reviews.
One mobile tech serves the area, and that works for a reseal, a vent cover swap, or a leak you can pinpoint. It does not work for a full membrane replacement or a soft, rotted deck. Call first and describe the damage, and expect an honest answer about whether it needs a shop bay.
Two of the listed shops do warranty work, so start there if your rig is still covered. Get pre-approval from the warranty company before any work starts, and ask the shop to photograph the damage. Approval can take a few days, so do not wait for the leak to get worse.
