Tar patch removal
Failed tar patches are stripped and replaced with real flashing so the repair does not depend on sealant.

Chimney Flashing Repair Natrona Heights, PA
A Natrona Heights chimney technician can reset loose flashing, replace rusted pieces and add a cricket where water piles up behind the chimney, before the leak rots the roof deck and framing. Dial (724) 604-6450 to talk with a local chimney sweep about the flashing.
The joint where a chimney passes through the roof is one of the most leak-prone spots on any house, and flashing is what keeps it dry. A chimney and a roof never move together perfectly, so the flashing is made of separate overlapping pieces rather than one solid seal. Eventually caulk cracks, fasteners loosen, steel rusts and the top edge of the flashing separates from the brick.
Proper flashing has a few distinct parts. Along the sides, individual step flashing pieces are layered with the shingles, while counter flashing is let into the mortar joints and lapped over them. The low side gets an apron, and the high side gets a back pan or, on wider chimneys, a cricket that splits the water around the chimney.
When you call about a flashing leak in Natrona Heights, a few details help. Mention where the water shows up, how often it leaks and how old the roof is. If you can see black tar smeared around the chimney, say so, because that usually means earlier patches have already failed.
If the problem goes deeper than it first looked, a Natrona Heights chimney sweep may also recommend chimney leak repair or chimney waterproofing.

How chimney flashing repair works
The goal is a joint that sheds water without relying on sealant.
Inspect the roof line
All four sides of the chimney are checked, because a leak on one side often starts somewhere else. The attic side of the roof deck is checked for rot as well.
Rule out the masonry
A water test may be used to confirm the flashing is really the problem. It makes sure the repair matches the actual source.
Strip failed material
Failed sealant and damaged flashing come off so the new work starts on a clean, sound surface. Soft or rotted sheathing under the old flashing is repaired first.
Side flashing
New step flashing is installed piece by piece along the sides, interwoven with each course of shingles. The front apron and a self-adhering membrane around the chimney add a second line of defense.
Set counter flashing
The top layer is set into the masonry itself, overlapping the step flashing below. Surface-mounted flashing held on by caulk alone is avoided because it fails quickly.
Add a cricket
Where water pools behind the chimney, a cricket, also called a saddle, is built to shed it. It solves the most common cause of leaks on the uphill face.
What is included
What flashing repair covers
Front flashing
The apron across the downhill face is replaced or resealed where water from the chimney face drains off.
Counter flashing
The top layer of flashing is renewed and properly let into the mortar joints instead of being held on with caulk.
Crickets
A saddle is framed on the uphill side so debris and ice stop collecting there.
Side flashing
Rusted or missing step flashing along the sides is replaced so water runs down the roof instead of under it.

Chimney Flashing Replacement Natrona Heights, PA
When flashing is rusted, bent or covered in years of patches, replacing it outright is usually smarter than another repair. It is a full redo of the joint, from the underlayment up to the counter flashing in the mortar. Reusing worn flashing under new shingles is one of the most frequent causes of chimney leaks on newer roofs.
If you are replacing the roof on a Natrona Heights home, that is the ideal time to replace the chimney flashing too. Coordinate the chimney sweep and the roofer so the step flashing goes in with the shingles and the counter flashing is set into the brick. While everything is exposed, a quick look at the crown, cap and upper mortar joints can save a second trip onto the roof.

Chimneys in this climate
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: rain and melting snow soak into the crown and joints, then freeze and push them apart, which is how cracks, loose bricks and leaks start. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Natrona Heights is usually booked in the fall, before the first cold night.

Chimney Flashing Repair FAQ
Do I need new chimney flashing when I replace my roof?
Doing it with the new roof is the smart move in most cases. Step flashing is woven in with the shingles, so the roof has to be open to replace it properly anyway. Old flashing reused under a new roof often leaks within a few years.
Should I repair or replace my chimney flashing?
What the metal looks like decides that. If the flashing is in good shape but the counter flashing has pulled out of the mortar, it can often be reset and resealed. Once flashing has rust holes or years of patches, replacing it is more reliable than another repair.
What is a chimney cricket?
Also known as a saddle, a cricket is a small roof section behind the chimney that diverts runoff to either side. Wide chimneys block a lot of runoff, and without a cricket that water sits against the flashing. Common building codes call for a cricket on chimneys wider than about thirty inches, unless the chimney sits at the ridge.
How do I know if my chimney flashing is leaking?
The most common sign is a water stain on the ceiling or wall right next to the chimney, or wet wood beside the chimney in the attic. Where the water appears is a clue: the firebox suggests the top of the chimney, and the ceiling beside it suggests flashing. A controlled water test settles it.
Why does my chimney flashing keep leaking after it was sealed?
Caulk and roofing tar only seal the surface, and they crack and pull loose as the chimney and roof expand and contract. When the flashing itself is the problem, sealant just hides it for a season. Sometimes the source is the masonry or crown above, not the flashing at all.
