RV roof leaks: small now, expensive later.

What usually fails

RV roofs (rubber EPDM, TPO, fiberglass, or aluminum) rarely fail in the middle — they fail at the edges and penetrations:

• Aged lap sealant — the self-leveling sealant around vents, skylights, antennas, and AC units cracks and lifts with sun and age; it's a maintenance item, not a lifetime material.
• Seams and trim — front/rear cap seams and side trim joints open up as the RV flexes down the road.
• Vent and skylight flanges — brittle plastic cracks, especially after years of valley heat.
• AC gasket compression — the foam gasket under the roof AC flattens over time and lets water track inside (the "AC leak" that isn't the AC).
• Tree and debris damage — foothill oak and pine country drops branches; punctures hide under leaf litter.
• Membrane wear — rubber roofs chalk and thin; black streaks showing through the white surface mean the membrane is wearing out.

Symptoms worth calling about

• Water stains, bubbling, or soft spots on the ceiling or walls
• Drips during rain that stop when it stops — classic seam/sealant leak
• Musty smell after storage, especially after winter rain
• Visible cracks or lifting in the sealant around roof fixtures
• Soft or spongy roof areas when walking the roof (or a tech's report of them)
• Delamination — wavy, bubbled exterior sidewalls

What a mobile tech can and can't do on site

On site: full roof inspection with photos, resealing of all fixtures and seams, vent/skylight replacement, AC gasket replacement, small puncture and tear repairs, and roof coating systems on suitable roofs. Resealing is a one-visit job in most cases, weather permitting.

Honest limits: if water has been getting in for a while, the damage under the roof — rotted decking, wall framing, insulation — can turn a reseal into a structural repair that belongs in a shop with the roof opened up. Coatings also aren't a fix for a roof that's already saturated; a reputable tech will probe for soft decking first and tell you if coating money would be wasted.

Have this ready when you call

• Where does water show up inside — and can you snap a photo of the stain?
• Roof type if you know it (rubber, fiberglass), and when it was last resealed
• Is the RV under trees, and is it stored covered or open?
• Access: can a ladder reach the roof safely where it's parked?
• RV year/make/model and where it's parked

Roof repair in the foothills

Roof work concentrates where the trees and the rain are:

• RV roof repair in Placerville — pine needles, storm limbs, and the twice-a-year inspection habit.
• RV roof repair in Auburn — oak litter on uncovered acreage rigs along I-80 and Highway 49.
• RV roof repair in Grass Valley — chronic moisture and needle mats under full pine canopy.
