Chimney Crown Repair
The crown is the chimney's roof. When it cracks, water pours into the masonry below — so we seal and restore it.
The crown is the sloped concrete or mortar slab at the very top of the chimney, covering the masonry around the flue. Its job is to shed water away from the structure — and when it cracks, which it inevitably does over years of sun and freeze-thaw, water flows straight down into the masonry, one of the leading causes of chimney deterioration.
Roosevelt Chimney Works repairs chimney crowns before that damage spreads. Depending on the crown's condition, repair ranges from sealing cracks with a specialized crown coating to rebuilding a crown that's crumbled beyond patching — covered on our crown rebuilding page.
Signs of crown damage
- Visible cracks across the top slab of the chimney.
- Chunks of the crown missing or crumbling.
- Water stains inside the house near the chimney.
- Efflorescence or spalling on the upper masonry.
- The crown lacks an overhang to direct water away.
How we repair crowns
For a crown that's structurally sound but cracked, we clean it and apply a flexible, waterproof crown coating that seals existing cracks and flexes with temperature changes rather than cracking again. It's a cost-effective repair that can add years of service.
When a crown has deteriorated beyond coating — crumbling, missing sections, or poorly built originally — we rebuild it properly with the right slope and an overhang to direct water clear of the masonry. We'll tell you honestly which your crown needs.
Pittsburgh & Western PA context
The crown is the most weather-exposed part of the entire chimney, taking full sun and every freeze-thaw cycle head-on. In Pittsburgh's climate, cracked crowns are one of the most common problems we find — and one of the most important to catch early, since the crown protects everything below it.
