Chimney Flashing Repair Cost Factors
Short answer
Chimney flashing repair cost depends on whether the flashing can be resealed or must be replaced, the width of the chimney, the roofing material and pitch, and any damage to decking or masonry next to it.
Why we do not list a price here
National averages published online vary widely in what they include and when they were collected, and they are not Houston prices. Our own prices depend on the specific chimney. Rather than print a number that may not apply, this guide explains what actually moves the price so you can judge any quote — including ours.
A written quote for your home, after assessment, is the only figure you should rely on.
Reseal, repair or replace
Resealing a sound flashing joint is quick. Replacing step and counter flashing means lifting roofing around the chimney and cutting new joints in the masonry.
