Skylight, Flashing and Vent Leak Repair in Boca Raton, FL

A solid field of barrel tile or architectural shingle is inherently effective at shedding vertical rainwater. However, whenever a pipe penetrates the roof deck, a skylight is installed for natural light, or a sloped roof meets a vertical stucco wall, the continuous water-shedding surface is broken.

These transition zones rely on sheet metal flashings (copper, galvanized steel, or aluminum) and specialized waterproof underlayments to redirect water back onto the tile surface. When flashings corrode from coastal salt air, crack from building settling, or separate due to dried-out caulking, water immediately slips behind the exterior wall and drips directly into your living room.

Skylights bring gorgeous Florida sunshine into kitchens and living rooms, but they are notorious leak sources if neglected. Skylight water intrusion typically stems from one of three distinct causes:

1. Deteriorated Perimeter Flashing Kits: The metal curb flashing and step flashing wrapping the skylight frame fails, allowing rainwater flowing down the roof slope to seep behind the frame.

2. Degraded Glass-to-Frame Gaskets: Years of intense South Florida heat and UV rays bake the rubber or butyl gasket holding the glass pane, causing it to shrink, crack, and admit water.

3. Interior Condensation Mimicking a Leak: In high-humidity coastal environments, inadequate attic ventilation or poor skylight insulation can cause warm, humid indoor air to condense on the cool underside of the skylight dome, dripping downward like an active roof leak.

Our technicians inspect both the exterior curb flashing and the interior glazing to determine whether a precision re-flashing kit or complete skylight replacement is necessary.

Roof valleys occur where two sloping roof planes intersect to form a V-shaped channel. Valleys handle enormous volumes of concentrated runoff during tropical downpours. In Boca Raton, leaves from nearby ficus, live oak, and mahogany trees collect in valley troughs beneath tile edges.

This organic matter traps moisture against the metal flashing, accelerating corrosion and rust holes. Over time, accumulated debris forms an invisible dam: during heavy downpours, rushing water backs up behind the dam, overflows the metal flanges, and pours directly under the tiles into the roof sheathing.

Many upscale Boca Raton homes feature complex multi-level Mediterranean architecture where lower first-story tile roofs terminate against second-story exterior stucco walls. These junctions require step flashing integrated with a counter-flashing reglet cut into the stucco.

If the original builder improperly caulked the flashing to the surface of the stucco without embedding it behind the drainage plane, coastal rain running down the vertical wall bypasses the flashing completely. This creates insidious wall rot, soaking drywall and insulation inside first-floor rooms. We properly cut reglets, install step flashings, and seal transitions with elastomeric waterproofing compounds.

Every Boca Raton home features multiple 2-inch to 4-inch plumbing vent pipes penetrating the roof to exhaust sewer gases. Standard rubber or neoprene vent boot collars degrade rapidly under Florida's intense sunlight, typically cracking and splitting within 6 to 8 years.

Once the rubber gasket splits, rainwater runs down the outside of the PVC pipe, dripping into bathrooms, laundry rooms, or attic crawlspaces. We replace failed rubber boots with heavy-duty lead pipe sleeves or UV-resistant silicone collar flashing systems designed to last 20+ years in coastal heat.

Properties situated along A1A, the Intracoastal Waterway, or within 3 miles of the Atlantic Ocean in Boca Raton, Highland Beach, and Delray Beach face severe airborne salt spray. Salt accelerates electrolytic corrosion on standard galvanized steel flashings, eating away protective zinc coatings and rusting through valley pans in under a decade.

Our network contractors utilize corrosion-resistant marine-grade copper, lead, or heavy-gauge Kynar-coated aluminum flashings on all coastal repairs to ensure long-term durability against ocean winds.

Homeowners often ask if a leaking flashing can simply be smeared with roofing tar. Quick-fix mastic caulking is a temporary stopgap that rarely lasts through a single South Florida summer. Heat causes tar to crack, bubble, and separate from metal within months.

Our approach is permanent: we carefully remove surrounding tiles, inspect the wood decking for rot, replace the deteriorated underlayment with high-temperature self-adhering modified bitumen, install custom-bent metal flashings, and neatly re-lay the existing tiles with fresh mortar pointing.
