The flashing around your chimney is one of the most common places a roof leaks. Simmons Roofing meticulously inspects and repairs chimney flashing across Southeast Missouri, ensuring a watertight seal that protects your home from water damage.
Flashing is the metal that seals the joint where your chimney passes through the roof, and it's doing one of the hardest jobs on the whole roof. Over time it corrodes, loosens, or its sealant fails — and it becomes one of the most common sources of roof leaks. Simmons Roofing meticulously inspects and repairs the flashing around your chimney, ensuring a watertight seal that protects your home from water damage.
Chimney leaks are especially sneaky because the water often shows up as a stain on a ceiling or wall well away from the chimney itself. We inspect carefully to confirm the flashing is the true source before we repair — so the fix actually solves the problem.
As a family-owned, licensed, insured, and bonded company, we back our repairs. Every job starts with a free, no-obligation inspection.
These are the flashing issues we most often find and fix.
Rusted, deteriorated flashing that no longer seals against water.
Cracked or dried-out caulk and sealant that has lost its grip.
Flashing that has pulled away, leaving gaps for water to enter.
Ceiling and wall stains near — or far from — the chimney.
Your chimney punches a hole right through your roof, and the flashing is the only thing keeping water out at that seam. When it fails, water runs straight down alongside the chimney into the structure — soaking framing, insulation, walls, and ceilings.
Chimney flashing leaks are deceptive. Because water travels along the framing before it drips, the stain inside can appear several feet from the chimney, which sends a lot of people chasing the wrong spot. We trace it back to the actual source.
A proper flashing repair restores a watertight seal and stops the damage before it spreads into an expensive structural problem.
Every chimney flashing repair is done to seal out water for good.

Almost always because of failed flashing — the metal seal where the chimney meets the roof. When that flashing corrodes, loosens, or its sealant dries out and cracks, water gets in at the seam. It's one of the single most common sources of roof leaks.
Chimney flashing is the metal that seals the joint between your chimney and your roof. It typically includes step flashing along the sides and counter flashing set into the chimney, working together to direct water away from the seam.
Watch for water stains on ceilings or walls near the chimney, visible rust or gaps in the metal, loose or lifted flashing, and dried or missing sealant. Because the stain can appear away from the chimney, an inspection is the surest way to confirm it.
In most cases, yes. The leak is usually in the flashing, not the chimney structure itself, so a flashing repair — replacing corroded metal and renewing the seal — solves the problem without any work on the chimney masonry.
Yes. Water entering at the chimney runs directly into your home's structure, and it damages framing, insulation, and drywall quickly. The sooner it's sealed, the less damage and expense you'll face — so don't put it off.
