Can roof flashing be fixed with sealant alone?

Sometimes. Small cracks and lifted edges can be sealed or patched, which HomeGuide prices at $200 to $500 on a chimney. Rusted, bent or missing metal has to be replaced, and in Broward the new piece must meet the HVHZ minimums, such as 26 gage G-90 galvanized steel or 0.025-inch aluminum.

How long does a rubber pipe boot last?

HomeGuide gives vent boots 10 to 20 years and notes that rubber breaks down faster in hot, sunny climates, while metal and good neoprene last longer. In the HVHZ, the code's default for pipes is a lead sleeve of at least 2.5 pounds per square foot, unless the roof system's approval details another method.

Which flashing metal holds up best near the beach?

Copper lasts longest, 50 to 100 years by HomeGuide's figures, at $15 to $30 a linear foot. Aluminum lasts 15 to 20 years and resists corrosion. The same guide says galvanized steel is not ideal for coastal areas, so ask which metal is on the quote if the house sits near salt air.

Roof Flashing Repair in Pompano Beach, FL

Typical cost: cost guides price a flashing repair at $200 to $500 and a full reflash at $500 to $1,500 or more; chimney flashing alone runs $300 to $1,800.
Time on the roof: about four hours of labor for a chimney reflash in one national estimate.
Trip minimum: many roofers charge $300 or more just to show up, so a single pipe boot is rarely cheap.
HVHZ code: lead pipe flashing must weigh at least 2.5 pounds per square foot with 4-inch flanges.

Pompano Beach Roofers gets a roofer close to you to look at the metal where the roof meets a wall, a chimney, a pipe or a valley. The fix is either a reseal of lifted edges or new metal woven back into the roofing, and the price gap between those two is wide.

Roof Flashing Repair by Where the Metal Sits

Step flashing where a shingle roof meets a painted stucco wall, with counter flashing set into the stucco above

Wall and step flashing

Wherever a roof slope runs into a stucco wall, as on a two-story CBS house or along a parapet, two pieces do the work: step flashing under the roofing and counterflashing over it. Broward's HVHZ code has the counterflashing built into the wall, set in a reglet or applied stucco-type, turned down at least 3 inches over the base flashing and side-lapped 4 inches. Getting the top edge right means cutting into the wall, so the stucco needs patching and paint afterward. Settle who does that before the job starts.

Metal counter flashing cut into the mortar joints of a brick chimney on a shingle roof

Chimney flashing

A chimney is flashed as a set: base flashing across the front, step flashing woven up the sides and counterflashing let into the mortar joints. What guides charge for it:

Resealing or patching lifted edges: $200 to $500
Reflashing a small chimney: $300 to $1,200; a large one: $500 to $1,800
Angi's 2026 national average for chimney flashing work: $1,000
Labor share of the bill: 60% to 70%

Pipe boots and lead jacks

In the HVHZ, every plumbing pipe gets a lead sleeve, a pitch pan or another method spelled out in the roof system's product approval. Lead must weigh at least 2.5 pounds per square foot with flanges of 4 inches or more. HomeGuide's range for vent repair, which covers boot swaps, is $400 to $800.

A metal gooseneck exhaust vent with its flashing base on a shingle roof

Roof vents (gooseneck, off-ridge, turbine)

Goosenecks, off-ridge vents and turbines aren't round pipes, so the code calls for curbs, collars or pitch pans under RAS 111 or the roof's approval. Static vents are the cheapest to fix. A powered attic fan may need an electrician as well as a roofer. When a vent is added or moved, it can't go in a valley: the HVHZ code bars any penetration there.

Valley metal

On shingle roofs in Broward, valleys and all perimeter edges must be metal, and the shingles along a valley are set in an 8-inch bed of approved adhesive or roofing cement. Ask to see the new valley metal before the shingles go back over it.

Questions to Ask Before a Flashing Repair

Which metal and what thickness?
The HVHZ floor is 26 gage G-90 galvanized or stainless steel, 16-ounce copper, 0.025-inch aluminum or 2.5-pound lead. Composite or nonmetal flashing needs its own product approval.
Is a permit being pulled?
Broward's code covers repairs as well as new roofs. The roof repair page explains when a small job needs one.
Will the roofing beside the flashing be relaid?
Step flashing is woven in with the shingles or tile, so a proper replacement lifts the courses next to it.
Who patches the stucco or the mortar?
Counterflashing set into a wall or chimney leaves a cut to close.
Is the leak really at the flashing?
Ask for photos of the failed piece before and after.
