Roofing: “Prefinished” Step Flashing
For a reroofing project, the bid specs say “prefinished step flashing” as opposed to unpainted galvanzied and then painted over. It’s supposed to match the drip edge and gable end metal.
There don’t seem to be any suppliers in Colorado, but I see it specified in bid specs and contract information I’ve found on the web.
Help! The job is starting soon.
Thanks,
Dave

I've always cut my own step flashings. You can get prefinished in rolls from the steel roofing retailers out there.
Excellence is its own reward!
If your dripedge and gable end metal are aluminum, then can't your flashings be aluminum coil stock to match ?

we always use prefinished coil stock to make our flashings.. in our case we use aluminum coil stock..
we haven't used mill finish aluminum in about 15 years, it's lighter guage than coil stock and doesn't look as good
you can also get painted galv. and painted steel

I think the specs are refering to step flashing not counterflashing which most of the old timers also call flashing cards.It is my understanding the last flashing is the counterflashing.
As not finding them every supplier I have ever done bussinees with has had them eirther in mill finnish or brown/black.
I'm no expert at roofing, but...........
Who cares what color step flashing is? If it's installed correctly, it's under the shingles and siding and out of sight.
Or am I missing something?

In this case, there was no step flashing orginally installed on the older house and we have to cut the siding up 1.5 to 2 inches and the step flashing will show.
There are other areas around chimmneys and skylights that may show as well
Normal option, you may have seen it, is to paint any exposed step flashing, but it always fades and looks "splotchy" after a few years.

Actually,boss---you are missing something.
If you look at a quality built older home you will see that the carpenters cared enough about the longevity of the project to hold the clapboards up off the roof maybe 1/2"--3/4". Among other things it prevents the end grain of the claboards from wicking up moisture from wet roof surfaces------besides GREATLY simplifying future roofing projects.Mill finish step flashing will be highly visible and crappy looking in that situation. Unfortuneately today----vinyl siders typically just drop the J channel right on the roof and nail it to the wall----such subtleties are ,it seems, beyond them. but wadda ya expect from vinyl siders?
I used to bend all my step flashing out of pre finished coil stock-----what a waste of time.Now we buy bundles of pre-finished,pre-bent step flashing----100 per bundle.Black,brown,white are the common in stock colors. 2x3x7, and 3x3x8 are the common sizes.
Well, I've never worked on a house with anything BUT vinyl siding. Never thought about holding the siding up off the roof if you used wood.

Yup.
Really.Crime wouldn't pay if the government ran it.
boss, here's two samples of colored flashing.. this is from brown coil stock.. the first is a breakflash with a double crimp to let the spring of the aluminum hold it down on the top course...
the 2d is an example of what stephen was talking about... holding the cedar clapboards up 3/4 to keep them out of the waterMike Smith Rhode Island : Design / Build / Repair / Restore
Thanks for the pics, Mike. Always interesting what you can learn here.
