Roof Flashing Repairin Austin, TX
Chimney flashing, step flashing, valley flashing, skylight flashing, and pipe boot replacement in Austin. Flashing failure is the most common cause of Austin roof leaks — we fix it permanently.
Flashing Types We Repair and Replace
Chimney Flashing
The most complex flashing on most Austin homes. Includes step flashing up both sides, counter flashing mortared into the chimney, and a custom saddle or cricket at the chimney's uphill side. Improper chimney flashing is the most common expensive leak on Austin homes with fireplaces.
Skylight Flashing
Skylights require manufacturer-specific integrated flashing systems. Generic flashing fails quickly in Austin's heat. We install proper factory kits with apron flashing, step flashing, and head flashing for complete weather protection.
Step Flashing
Where a sloped roof meets a wall (like a dormer or house addition), step flashing provides individual metal pieces at each shingle course. Improperly installed step flashing is a frequent Austin leak source, especially where additions join the original home.
Valley Flashing
Roof valleys concentrate water flow and require proper closed-cut, open, or woven valley installation. Austin's heavy rain events stress valley flashing — we install heavy-gauge galvanized or aluminum valley with proper headlap to handle the flow.
Why Flashing Fails in Austin
Austin's climate creates specific conditions that accelerate flashing failure. The city's dramatic temperature swings — from freezing winter nights to 100°F+ summer days — cause metal flashing to expand and contract significantly. This thermal cycling stresses the joints between flashing and roofing materials, breaking the watertight seal over time.
Additionally, Austin's humid subtropical climate promotes corrosion of galvanized steel flashing. Older Austin homes (built before 1990) often have original galvanized flashing that has rusted through or lost its coating. We use heavier-gauge galvanized or aluminum flashing that resists Austin's humidity and provides longer service life.
The most damaging flashing failure we see in Austin is around chimneys. Many Austin homes have chimneys that were reflashed at some point using caulk and surface-applied metal strips rather than proper step and counter flashing. These "repairs" last only 3–5 years before failing again. Proper chimney reflashing — removing the old chimney cap, cleaning the mortar joints, installing proper step flashing and lead-coated counter flashing — lasts 20+ years.
We provide complete written estimates before any flashing repair begins. Our assessments include photo documentation of all failing areas so you understand exactly what needs to be done and why. We don't use excessive caulk — we install properly formed metal that will protect your Austin home for decades.
Roof Flashing Repair FAQs — Austin TX
What is roof flashing and why does it fail in Austin?
Roof flashing is sheet metal installed at roof transitions, penetrations, and edges to direct water away from vulnerable areas. Flashing fails in Austin due to thermal expansion and contraction from extreme temperature swings, corrosion from humidity, and improper original installation. Flashing failure is the #1 cause of Austin roof leaks.
How do I know if my Austin roof has flashing problems?
Signs of flashing failure on Austin roofs include: water stains on ceilings near chimneys, skylights, or walls; visible rust or corrosion on metal flashing; flashing that is pulled away from the surface it's sealed against; missing sections of flashing; and caulk-covered flashing (a temporary fix that indicates previous failure).
How much does roof flashing repair cost in Austin?
Simple flashing repairs in Austin — resealing a pulled flashing or replacing a pipe boot — cost $150–$400. Complete chimney reflashing typically costs $500–$1,200. Valley flashing replacement runs $400–$800 per valley. We provide written estimates before any work begins.
Should flashing be repaired or replaced?
Most Austin flashing failures require replacement rather than repair. Caulk applied over failed flashing is a temporary fix — in Austin's heat, caulk degrades quickly and the underlying failure continues. Proper reflashing removes all old material and installs new metal flashing that will last 20+ years.
