Boral Flashing Replacement in Miami, FL

Boral Flashing Replacement: The Miami Owner’s Guide

We stock and install Boral-compatible flashing replacement for Miami homes, with most jobs running $320-$680 installed depending on linear footage, roof pitch, and whether adjacent underlayment needs attention. Same-day service is available when you call before noon, and our trucks carry the common Boral profiles used across Miami-Dade County. Most homeowners discover their Boral flashing has failed after a hard rain leaves water stains on ceiling drywall or they notice rust streaks weeping down exterior walls where the roof meets a vertical surface.

Which Boral Models This Applies To

Boral’s flashing systems vary by roofing line, and matching the right profile matters for keeping your warranty intact and water out. The Boral Saxony 900 Slate and Boral Villa 900 Concrete Tile lines use distinct step-flashing geometries, and their sidewall and headwall configurations are not interchangeable. If you’re not sure which Boral product is on your roof, check the underside of a loose tile in your attic space for the molded Boral stamp and date code, or look for a builder’s spec sheet from your original permit file at the Miami-Dade Building Department.

We carry both OEM Boral flashing and quality aftermarket equivalents that meet the same ASTM B-209 aluminum specs and 26-gauge minimum thickness. For older Boral installations in Coral Gables and Pinecrest, we often find the original copper step flashing has thinned to the point of pinholing. In those cases, we match the existing profile in modern aluminum or stay with copper if the homeowner prefers. Carlos Espinosa makes the call on-site after pulling a piece to measure, and we photograph what we find so you see exactly what we’re matching.

Signs Your Boral Flashing Replacement Is Failing

• Water stains on interior ceilings or walls near roof-wall junctions. This usually means step flashing has separated from the wall sheathing or the counter-flapping seal has broken. In Miami’s climate, the daily expansion and contraction from 90-degree afternoons to 75-degree nights works that joint loose faster than in cooler markets.
• Rust-colored streaks on exterior stucco or paint below roof intersections. Aluminum flashing doesn’t rust, but the fasteners and any steel drip edge behind it do. Those streaks are telling you water is getting behind the flashing and carrying oxidation down the wall.
• Lifted or curled shingles or tiles at the valley or wall edge. When flashing pulls away, it creates a gap that wind-driven rain exploits. We’ve seen this especially on Boral roofs in Miami Beach and Key Biscayne where salt air accelerates fastener corrosion.
• Granule loss or bald spots on asphalt adjacent to Boral tile flashing. This indicates chronic moisture wicking from a compromised flashing pan. The trapped water cooks the shingle in Miami’s UV, and the damage spreads outward from the leak point.
• Visible gaps or daylight through the attic at wall-roof intersections. If you can see light, water can follow. This is often the first sign on older Boral installations where the original builder used generic rather than Boral-specified flashing profiles.

Replacement Cost & What’s Included

What drives the range: roof pitch above 6/12 adds labor time, tile removal and reset is slower than shingle work, and some Miami homes built 1985-1995 have multiple flashing layers from prior repairs that need sorting out. Our quote includes the Boral-compatible flashing, fasteners rated for Miami-Dade wind codes, ice-and-water shield where the code requires it, and disposal. The 90-Day Done Right Promise covers the workmanship. If it’s not right, we make it right - no paperwork, no arguing.

DIY or Call Us?

There’s no spring tension or electrical hazard in flashing work, but there’s a reason we don’t encourage homeowners up on their own roofs. Miami’s tile roofs are brittle after twenty years of UV exposure, and stepping wrong cracks tiles that may no longer be in production. The bigger risk is misdiagnosing the leak source. Water travels, and what looks like failed flashing at the wall might be entry six feet away at a valley or vent.

What you can safely do from the ground: take photos of any stains or streaks, note which wall direction faces the weather when leaks occur, and check your attic during daylight for pinholes of light. Then call us. We’ll send a background-checked, uniformed technician who documents the actual roof condition with photos from your shingles or tiles, not from the driveway. Most Boral flashing replacements in Miami we complete in a single visit. Call (855) 837-1678 for an exact quote - estimates are free, and a live person answers around the clock.
