How a crown repair runs, step by step
Why the crown should project past the brick
A crown that stops flush with the brick face lets water run straight down the chimney. An overhang carries the water out beyond the face before it drops. That keeps the top courses of brick drier after every rain.
When a crown does not overhang, brick industry guidance suggests forming a drip another way, such as corbeled brick below it. On a new crown we build the overhang into the shape. On an existing one, we explain whether its projection is adequate or part of the reason the brick below is wet.
Crown work and the roof flashing stay separate
Water at the ceiling beside a chimney can come from the crown or from the flashing at the roof line. Both are water-shedding details, but they sit in different places and fail in different ways. Treating one for the other leaves the leak in place.
When we assess the crown, we also look at the flashing from the roof. If the flashing is the more likely path, we explain that and price it on its own line. The crown estimate covers only the top of the chimney unless you approve more.
Protecting the roof covering during crown work
Concrete, mortar and coatings can mark a roof if they drip or spill. The coating data sheet advises protecting the roof from inadvertent spills during application. We set out protection where material is mixed, carried and applied.
Tell us about roofing that marks easily or is near the end of its life. We would rather know before we step onto it. If a spill does happen, it is cleaned during the work rather than left to set. The written record notes any concern we saw on the roof around the chimney.
Common reasons chimney crowns deteriorate
Crowns fail for a handful of reasons. Shrinkage and temperature movement can crack the concrete. A missing bond break lets the liner push against it. Thin edges crumble, and flat tops hold water. Mortar washes may not last as long as a formed crown.
Knowing the reason helps choose the repair. Cracks from a tight liner joint need that joint freed. Water standing on a flat top needs slope. We explain which cause fits your crown, so the repair addresses it rather than just the visible damage.

Chimney crown work, questions and answers
Will you tell me if the brick under the crown is damaged?
Yes. Once the old crown is off, the top courses are easy to see. If loose brick or failed joints turn up, we stop, show you the condition and price that work as a separate item before continuing.
What does the free inspection include for a chimney crown?
We look at the crown surface, edges, slope, overhang and the seal at every flue, plus the cap fixings and the brick just below. You hear the findings on site and receive a free written estimate that keeps each item separate.
What should I tell you when I call about the crown?
Mention what you have seen, such as concrete pieces on the roof, a stain inside or cracks visible from the yard. Tell us about earlier patches or coatings and any appliance that vents through the chimney.
