Serving Miami, FL
Finding the source of a roof leak is harder than it looks. Water that appears on your ceiling in one location often entered the roof 10, 15, or even 20 feet away — traveling along rafters, decking, and insulation before dripping onto your ceiling. A contractor who patches the obvious wet spot without tracing the leak to its true source is setting you up for a repeat call. Pro-Tech Roofing uses a systematic leak detection process developed over 20 years of diagnosing Miami roof leaks. We trace every leak to its origin, explain exactly what we found and why it's leaking, and repair it with NOA-approved materials backed by our workmanship warranty. We don't guess — we inspect.
Flashing is the metal or membrane material that seals the joints between your roofing system and vertical surfaces — chimneys, walls, vents, skylights, and roof edges. It's the most common source of roof leaks in Miami, and it's the first thing our technicians inspect on every leak call.
Flashing fails in Miami for several reasons. The sealant used to seal flashing joints — typically a polyurethane or silicone caulk — degrades under Miami's intense UV radiation and heat. Most sealants have a useful life of 5–10 years in South Florida's climate before they crack, shrink, and pull away from the surfaces they're sealing. Once the sealant fails, water finds its way in immediately.
Step flashing — the individual pieces of metal that seal the joint between a sloped roof and a vertical wall — can separate from the wall as the building settles and the materials expand and contract with temperature changes. When step flashing separates, water runs directly down the wall and into the structure.
Counter flashing — the metal cap that covers the top of step flashing — can pull away from the mortar joints in masonry walls or from the stucco on CBS walls. When counter flashing separates, the entire step flashing system below it is exposed to water infiltration.
Drip edge flashing at the eaves and rakes is often improperly installed or missing on older Miami homes. Without proper drip edge, water can wick back under the roofing material at the edges and cause rot in the fascia and soffit.
Pro-Tech Roofing repairs all types of flashing failures. We remove deteriorated sealant, clean the surfaces, and apply new sealant rated for Miami's UV environment. For flashing that has physically separated or corroded, we replace it with new galvanized or aluminum flashing properly integrated with the roofing system.
Roof valleys — the V-shaped channels where two roof planes meet — are high-water-flow areas that are particularly vulnerable to leaks in Miami's heavy rainfall. During a South Florida downpour, valleys can carry hundreds of gallons of water per hour, and any weakness in the valley system will be found quickly.
Open metal valleys use a continuous piece of metal (typically galvanized steel or aluminum) to channel water down the valley. Over time, the metal can corrode, the sealant at the edges can fail, and debris accumulation can cause water to back up under the roofing material. We clean valley debris, reseal valley edges, and replace corroded valley metal as needed.
Closed valleys on tile roofs — where tiles are cut and installed over the valley — are common in Miami and require careful installation to prevent leaks. When tiles are cut improperly or the underlying valley flashing is inadequate, water infiltrates at the cut edges. We repair closed valley leaks by removing the affected tiles, installing proper valley flashing, and reinstalling the tiles with correct cuts and sealing.
Woven valleys on shingle roofs — where shingles from each side of the valley are interwoven — are vulnerable to granule loss and shingle deterioration at the valley center, where water flow is highest. We repair woven valley leaks by replacing the deteriorated shingles in the valley area and installing new valley flashing beneath them.
Valley debris accumulation is a maintenance issue that leads to leaks. Leaves, seed pods, and other debris accumulate in valleys and create dams that cause water to back up under roofing materials. We clear valley debris as part of our maintenance visits and recommend keeping trees trimmed away from the roof to reduce debris accumulation.
Chimneys are one of the most complex leak sources on any roof because they have multiple potential failure points — and a chimney leak often involves more than one of them simultaneously. Pro-Tech Roofing addresses all chimney leak sources in a single visit rather than patching one at a time.
Chimney crown failure is the most common chimney leak source. The crown is the concrete cap that covers the top of the chimney, sloping away from the flue to direct water off the chimney. Chimney crowns crack from thermal cycling and Miami's temperature swings, allowing water to enter the chimney structure and eventually the home. We repair cracked crowns with elastomeric crown sealant or replace severely deteriorated crowns entirely.
Chimney flashing has two components: base flashing (step flashing) that seals the joint between the chimney and the roof surface, and counter flashing (cap flashing) that is embedded in the chimney mortar joints and covers the top of the base flashing. Both components must be properly installed and sealed to prevent leaks. In Miami's climate, the sealant at these joints typically needs replacement every 5–10 years.
Mortar joint deterioration on masonry chimneys allows water to infiltrate the chimney structure. Miami's humidity and occasional freeze-thaw cycles (rare but possible) cause mortar to crack and erode over time. We tuckpoint deteriorated mortar joints as part of chimney leak repairs.
Chimney cap failure — the metal cap that covers the flue opening — allows rain to enter the flue directly. A missing or damaged chimney cap is an immediate source of water intrusion. We replace damaged chimney caps with properly sized, corrosion-resistant caps.
For stucco-clad chimneys common on Miami homes, we also inspect the stucco for cracks and separation that allow water infiltration. Stucco repairs are often necessary as part of a comprehensive chimney leak repair.
Skylights are a popular feature in Miami homes — they bring in natural light and can improve ventilation. But skylights are also a common source of roof leaks, and skylight leaks are often misdiagnosed. What appears to be a skylight leak is sometimes actually a flashing leak near the skylight, or condensation from a poorly insulated skylight shaft.
True skylight leaks — where water is entering through the skylight itself — typically result from failed sealant at the skylight frame, cracked or damaged glazing, or a failed gasket between the glazing and the frame. We inspect the skylight carefully to determine whether the leak is coming through the skylight or around it.
Skylight flashing leaks are more common than true skylight leaks. The flashing that seals the joint between the skylight curb and the roofing surface is subject to the same deterioration as other roof flashing — UV degradation of sealant, thermal movement, and corrosion. We reseal or replace skylight flashing using compatible materials and proper installation techniques.
Condensation is often mistaken for a skylight leak. When warm, humid Miami air contacts the cool surface of a skylight, condensation forms and can drip onto the ceiling below. This is particularly common in air-conditioned homes where the temperature differential between the interior and the skylight surface is large. We can identify condensation issues and recommend solutions including improved skylight insulation and ventilation.
For skylights that are beyond repair — typically older units with failed glazing or severely deteriorated frames — we recommend replacement. Modern skylights are significantly better than older units in terms of UV resistance, thermal performance, and leak resistance. We can remove the old skylight and install a new unit with proper flashing integration.
Flat roofs in Miami are subject to specific leak mechanisms that differ from sloped roofing. Pro-Tech Roofing has extensive experience diagnosing and repairing all types of flat roof leaks throughout Miami-Dade County.
Membrane blistering is one of the most common flat roof problems in Miami. Blisters form when moisture or air becomes trapped between membrane layers and expands under Miami's intense heat. Small blisters are often stable, but large blisters or blisters that have burst create immediate leak vulnerabilities. We repair blisters by cutting them open, thoroughly drying the substrate, and patching with compatible membrane material.
Seam and lap failures are the primary source of flat roof leaks. The seams where membrane sections overlap are the most vulnerable points in any flat roofing system. Heat, UV exposure, and thermal cycling cause seam adhesives and heat welds to fail over time. We reseal failed seams using compatible adhesives or heat welding, depending on the membrane type — modified bitumen, TPO, or EPDM.
Drain and scupper failures cause water to pond on flat roofs, accelerating membrane deterioration and eventually causing leaks. Clogged drains are the most common cause of ponding — Miami's heavy rainfall and abundant vegetation mean drains can clog quickly. We clear all drains and scuppers and inspect the drain flashing for deterioration.
Penetration failures at HVAC equipment curbs, pipe penetrations, and vent stacks are a frequent source of flat roof leaks. The flashing and sealant around penetrations deteriorates faster than the membrane itself due to the thermal cycling caused by the equipment. We reseal all penetrations using compatible materials rated for Miami's UV environment.
Parapet wall flashing failures allow water to enter at the junction between the flat roof membrane and the parapet wall. We inspect and repair parapet flashing as part of every flat roof leak investigation.
When a Miami storm causes sudden roof damage and active leaking, emergency tarping is the immediate priority. Pro-Tech Roofing deploys emergency tarping crews throughout Miami-Dade County to stop active water intrusion while we assess the damage and plan the permanent repair.
Emergency tarping involves securing heavy-duty polyethylene tarps over damaged roof areas using battens and fasteners that won't cause additional damage to the roofing system. A properly installed emergency tarp can prevent water intrusion for several weeks while permanent repairs are arranged. We use commercial-grade tarps — not the lightweight tarps available at hardware stores — that can withstand Miami's wind and rain.
Documentation is critical when a roof leak is the result of storm damage. Insurance claims for roof damage require evidence that the damage was caused by a covered event — not pre-existing deterioration or lack of maintenance. Pro-Tech Roofing documents all storm damage with detailed photographs, written descriptions, and measurements that meet the requirements of Florida insurance carriers.
We work with all major insurance carriers and can assist you through the claims process from initial documentation through final settlement. Many Miami homeowners are surprised to find that storm-related roof damage is covered by their homeowner's insurance, and we have extensive experience helping clients navigate the claims process and ensure they receive the full coverage they're entitled to.
