Chimney Flashing — The #1 Source of Chimney-Area Leaks in Suffolk County
When Suffolk County homeowners call about a roof leak near the chimney, the culprit is chimney flashing in the majority of cases — not the roof shingles. Chimney flashing is the metal system that seals the joint between the chimney and the roof surface. It consists of step flashing (L-shaped pieces woven between shingles along the chimney sides), counter flashing (embedded into the chimney mortar joints to cap the step flashing), and a saddle or cricket behind the chimney on steeper-pitched roofs. Any one of these components can fail: mortar cracks release counter flashing, step flashing corrodes, previous repairs using caulk or roofing cement fail within one to two seasons. DME Maintenance diagnoses the exact failure point and repairs or replaces only what has failed — no unnecessary reroofing.

Frequently Asked Questions — Suffolk County Chimney Services
What is chimney flashing and why does it leak?
Chimney flashing is the metal system sealing the joint between your chimney and roof. It consists of step flashing along the chimney sides and counter flashing embedded into the chimney mortar joints. It leaks when mortar cracks release the counter flashing, step flashing corrodes, or previous caulk repairs dry out and crack — typically within 1–3 years.
How do I know if my roof leak is actually a chimney flashing problem?
If water staining appears on your ceiling or walls near the chimney base — especially during rain but not snow melt — the leak source is almost always chimney flashing, not the roof shingles. DME Maintenance provides free on-site diagnosis to confirm the exact source before any repair work begins. Call 516-690-7471.
How much does chimney flashing repair cost in Suffolk County?
Chimney flashing repair cost varies significantly by the extent of failure and whether counter flashing re-embedding, step flashing replacement, or saddle/cricket work is needed. DME Maintenance provides free on-site estimates with written scope and photos — no obligation. Call 516-690-7471 to schedule.
Can I fix chimney flashing myself with caulk or roofing cement?
Caulk and roofing cement are temporary measures that typically last 1–3 seasons before drying and cracking. They do not address the root cause — usually counter flashing that has pulled free from the chimney mortar joint. DME Maintenance re-embeds counter flashing into fresh mortar for a permanent repair.
Should chimney flashing repair be combined with other work?
Often yes. Flashing failures usually accompany deteriorated mortar joints — the same moisture that compromised the flashing has worked into the masonry. DME Maintenance assesses the full chimney during every flashing repair and recommends combining with ChimSaver waterproofing to protect the repaired surfaces.
