No flat price applies. Your number is set by flashing points, material and damage extent.
Every Flashing Point Prices Differently
A flashing quote is a list, not one number. Each point is priced on its own labor and metal.
-
01
Highest
Chimney flashing
Chimney flashing runs highest, since cutting a proper reglet into masonry takes more labor than any other point.
-
02
By the foot
Valley flashing
Valley flashing follows close behind on longer roofs, priced by linear footage down the slope.
-
03
Labor-heavy
Step flashing
Step flashing costs less per piece but adds up in labor, since it is set one short section at a time along a wall.
-
04
Fiddly
Vent pipe boots & skylight flashing
Small individually, but fiddly work around a curb or pipe collar adds time.
-
05
Lowest
Drip edge & counter flashing
Usually land as the cheapest line item, unless rust or a full run is involved.

Which points need attention?
Pick every point you have seen leaking, lifting or rusting. More than one is common.
Which material goes in?
Not sure yet? Pick the one you are leaning toward; the estimate visit covers the choice.
How far has the damage spread?
A single reseal and a full re-flash are different jobs.
What are the roof pitch and access like?
A steep roof needing staging adds labor regardless of metal.

Three Choices Move It Most
Every answer nudges the read, but these three shift a flashing quote the furthest.
-
Material choiceCopper costs more than aluminum but outlasts it by decades.
-
Access and pitchA steep roof needing staging adds labor regardless of metal.
-
Single spot vs full runA single reseal is a different job from re-flashing a whole chimney or valley.
One Spot Reseal Or Re-Flash The Whole Run
The same leak can be priced two very different ways. Here is how the two jobs compare.
Swipe to see both columns
| Compared on | Spot resealOne leak point, one section | Full re-flashA chimney, valley or roof edge |
|---|---|---|
| Typical trigger | One leak point, sealant cracked or lifted | Rust through the metal, repeat leaks, run past its service life |
| What's involved | Clean the joint, reseal or reset one section | Pull the old flashing, check the decking, set new metal the full length |
| How long it holds |
Months to a couple years
|
Well beyond a decade with the right material
|
A Reseal Only Buys Time
A reseal buys time on a small failure but will not hold if the metal underneath is already rusted through, worth checking before you pay for a repair visit.
Don't Wait For The Estimate

Property types we price
Your Property Changes The Job
A single-family home or townhouse usually has a handful of flashing points and an easy roof to access. Multi-family, condominium, and commercial buildings change that math: more chimneys and vents, steeper sections, sometimes lift or staging equipment just to reach the work.
If flashing damage keeps showing up across an aging roof, that can point to a bigger roof-wide cost question.
We price residential, multi-family, condominium, commercial, office, retail, and apartment building roofs to match what each one actually needs.

What The Estimate Actually Checks
Before MNM Roofing gives you a number, someone checks every flashing point. That is what makes the figure measured, not guessed.
- 01Every flashing point, one by one
- 02Sealant condition
- 03Rust or lifting metal
- 04Counter flashing still sealed tight against the wall
- 05Decking underneath for water it has taken on
Full flashing replacement work is licensed and insured, with a warranty on the finished job.
Flashing Cost FAQ
Short answers on minimums, materials, the estimate and insurance.
Yes. Small jobs carry a minimum to cover the trip and labor, even for one reseal. Access and distance to a safe working area move the exact figure.
Yes. Galvanized steel costs least upfront, aluminum sits in the middle, copper costs most and lasts longest.
No. It is free, and it is how you get an exact number instead of a guess.
Sometimes, if the damage traces to a storm or covered event rather than age or wear. Bring your policy questions to the estimate visit and we will tell you honestly whether it looks worth filing.
