Bring clear photos of the flashing and written notes about where and when water appears. We find those items, plus roof age and any past repair records, let us assess flashing details far faster during a first roof repair conversation.
Why flashing matters for roof repair
Flashing is the thin metal and seals that protect roof junctions from water intrusion. Flashing sits where the roof meets chimneys, walls, valleys, skylights and vents. When flashing fails, water follows seams and gaps into sheathing and interior finishes. For homes in Downtown Pittsburgh, where older roofs and close building setbacks are common, flashing problems are a frequent source of leaks.
As a general contractor with more than 30 years of local experience, we rate flashing issues by location, material, and the condition of adjacent roofing and siding. Early, clear information from you speeds that evaluation and reduces the chance of unnecessary work.
What to gather before your first conversation
The items below help us decide whether a simple repair, flashing replacement, or broader roof work is likely. Collect what you can, and we will use it to prepare for an efficient site visit.
Bring these items
- Photos of the flashing from the ground or a safe vantage. Focus on chimneys, wall step flashing, valleys and around skylights.
- Photos of interior staining, ceiling spots, and attic areas near the leak.
- Notes on where and when you see water: which floor, which room, and whether leaks appear during light rain or heavy storms.
- The roof age and last full roof service date, if known.
- Records of any prior roof or flashing repairs, and who did them.
- Information about recent roof changes, like new siding, new skylights, or replaced gutters.
- Access information, such as tight alleyways or steep roof pitches that affect inspection logistics.
Pro tip: If you can safely take a short video showing water running during light rain, that is often the fastest way for us to see where water is migrating.
What good documentation lets us do
Well organized photos and notes let us:
- Distinguish between flashing failure and other causes like clogged gutters or failed underlayment.
- Estimate whether flashing patches or full replacement are reasonable options.
- Plan whether adjacent trades, such as siding installers or chimney masons, will be needed.
- Identify permit questions early for Downtown Pittsburgh properties.
When you provide good information up front, we can schedule the right crew and tools, keep the visit focused and limit disruption to your home or building.
How we evaluate flashing on site
- Visual inspection. We check flashing seams, fastener condition, and whether flashing laps correctly against roofing and cladding.
- Water path tracing. We look above the interior stain to find probable entry points rather than relying only on where water shows up inside.
- Material assessment. We identify flashing metal type, sealant condition and any corrosion or separation.
- Scope definition. We decide if a localized repair, reflash, or larger roofing work and trade coordination are required.
Watch out: Do not attempt to remove or pry loose flashing yourself. That can let more water in and hide the actual failure point. Leave inspection above the eaves to a professional for safety reasons.
Common flashing problems we see in Downtown Pittsburgh
- Step flashing that is not integrated with wall cladding, letting water run behind siding.
- Counter flashing not seated against chimney mortar joints.
- Valley flashing improperly lapped or undersized for the roof pitch.
- Skylight curb flashing gaps after resealing or roof replacement.
Local building access and older masonry chimneys increase risk of flashing gaps. For guidance on managing moisture in assemblies, see our moisture management topic page for practical context and trade coordination tips about moisture management.
Permits, licensing and industry guidance
Flashing work can require permits depending on the scope and the city neighborhood. For Downtown Pittsburgh projects, local permit rules and inspection requirements are handled by the City of Pittsburgh Department of Permits, Licenses and Inspections. We review permit needs before we schedule any roof or flashing replacement so the work meets municipal requirements pittsburghpa.gov/dcp.
As a general contractor, we follow industry best practices for flashing and roof-water management. For background on the general contractor role see the Wikipedia entry for general contractor General contractor, and for trade guidance we consult standards and recommendations published by the Associated General Contractors of America agc.org.

Quick guide to deciding when to call a pro
If you see any of these, plan to have a professional evaluation rather than a do it yourself fix.
- Recurring interior stains after rain events.
- Visible gaps, rust, or separation at flashing seams.
- Recent roof or siding work near the leak area.
- Complex roof geometry, adjacent masonry, or steep access that increases safety risk.
Key takeaway
Before your first roof repair conversation about flashing details, gather clear photos of the flashing and interior stains, note where and when leaks appear, and collect any roof history. Those items let us triage the problem, plan a safe inspection, and determine whether flashing repair or broader roof work is appropriate.
Frequently asked questions
What is step flashing and why does it fail?
Step flashing is individual metal pieces installed where a sloped roof meets a vertical wall. It fails when the pieces are not lapped correctly, when siding was installed over the flashing, or when sealant and fasteners deteriorate. Properly integrated step flashing must shed water onto the roof surface, not behind the wall cladding.
Can flashing be repaired or does it have to be replaced?
It depends on condition and location. Small separations and sealant failures can sometimes be repaired. Corroded, undersized, or incorrectly installed flashing typically requires replacement. We evaluate on site and explain the tradeoffs.
Will flashing work require a permit in Pittsburgh?
Minor repairs may not need a permit, but larger replacement work often does. We check City of Pittsburgh permit requirements and include that in our project planning so inspections and approvals go smoothly.
Should I remove interior drywall to find the leak?
Not immediately. We first trace the water path from the exterior and attic. Opening interior finishes is sometimes necessary to repair concealed damage, but we use noninvasive diagnostics first whenever possible.
