FAQ: roof vents, skylights, and seals in Port St. Lucie
Q: How much does rv roof repair for a leaking vent cost in ?
A: A full 14x14 vent replacement runs $189 to $325 installed, depending on powered fan, garnish depth, and roof condition. If the wood ring is soft, add $75 to $150 for a rebuild. A lid-only swap is $89 to $149. We include butyl, stainless screws, and self-leveling lap sealant.
Q: Can you do same day rv repair after a PSL storm?
A: Yes. Call by noon and we can usually fit you in the same day. We stock vents, lids, skylights, and sealants on the truck. Emergency after-hours service adds $95, but it beats soaked insulation and a ceiling panel sag.
Q: Should I use silicone to stop a roof leak on EPDM?
A: No. Silicone doesn’t bond well to EPDM, and it contaminates the surface for future repairs. Use butyl under the flange and Dicor or Alpha self-leveling lap sealant on top. For torn seams, Eternabond tape under the lap seal works great.
Q: How often should I reseal my RV roof in coastal Florida?
A: In and the Treasure Coast, reseal every 12 to 24 months. The UV, heat, and summer thunderstorms age sealants faster than inland areas. We do quick annual inspections and touch-ups for many customers during spring.
Q: Can you replace a cracked skylight without removing the whole frame?
A: Usually yes. If the frame and wood substrate are solid, we can replace just the dome, reset with butyl, and reseal the flange. That runs $450 to $650. If the frame’s warped or the wood is soft, we rebuild the ring and set a full new unit.
Q: What’s the difference between EPDM and TPO for sealing?
A: EPDM likes Dicor 501LS and mineral spirits cleanup. TPO bonds well with Alpha Systems 1010 and isopropyl alcohol cleanup. We use non-sag versions on verticals. Using the wrong cleaner or sealant can cause poor adhesion and early failure.
Q: Do you service RV parks and storage lots around St. Lucie West and Tradition?
A: We do. We cover St. Lucie West, Tradition, Torino, the Civic Center area, and along US-1. Drive time is 10 to 25 minutes. We also handle Stuart, Jensen Beach, Fort Pierce, and Palm City with a small trip fee.
Q: Can you install a Maxxair cover so I can vent during rain?
A: Yes. We install Maxxair covers over standard 14x14 vents for $139 to $219 installed. Great for our afternoon showers. You can leave the vent open and still keep water out, which helps with humidity and keeps smells down.
Q: Do you offer rv refrigerator repair or ac repair during the same visit?
A: Yes. We handle rv refrigerator repair, rv ac repair, rv furnace repair, and rv generator repair. If we’re already onsite for a roof issue, we can usually add an appliance diagnosis at a discount.
Real jobs this month in Port St. Lucie
- St. Lucie West, Class C, bathroom vent fan dead. We found a seized motor, upgraded to a Fan-Tastic unit, resealed the flange, and added a Maxxair cover. Total: $565. Time on roof: 1 hour 40 minutes. Tradition, fifth wheel skylight cracked from hail in Georgia. Dome swap, wood ring rebuild, Eternabond perimeter, and lap seal. Total: $779. In and out in 2 hours 50 minutes. Torino, travel trailer with mystery drip. Lap sealant looked fine. We moisture-mapped and found a loose cable entry. New gland, butyl, and seal. Total: $189. Leak solved.
We see this pattern a lot. The obvious crack isn’t always the leak. Testing matters. We use a moisture meter and, when needed, a hose test in sections so we don’t flood the coach.
Maintenance tips to avoid the next leak
You don’t need to baby the roof, just give it 20 minutes every few months. Here’s the simple routine we recommend to every PSL customer:
- Rinse dust and salt spray, then inspect seams around every opening. Look for pulled edges, pinholes, and rusted screws. Check vent lids for UV chalking and brittleness. Gently press the ceiling near vents and skylights for soft spots. Schedule a reseal before hurricane season if it’s been 18 months.
That’s it. Catch it early and you’ll never see a ceiling panel sag.
