DIY: Metal Roof Cricket Behind a Chimney

Metal roofing works great but having a cricket behind a chimney that exits onto the roof is challenging. Here is our solution to the problem. Each roof is different so I did not document every single step. Huge thanks to my Jake and Charlie for helping (or doing) this project.

20 and counting years of install experience and here. Got to say dam good job on this.

I dont wish to be a hater or troll. But this is wrong.atleast in europe, Norway. You would lose your job if you did that.

What happens in Norway when a roof meets a chimney and snow builds up behind it? Anything poking out of a roof is a spot it could leak so I am open to other suggestions.

@@MakerMaxCorbett , We get a thinmetall worker who solves the problem for us. We call it : Båndtekking. Look it up :)

@@akiiakilius3476 Don't just brush us off. Tell us exactly what you would do instead. Any troll can say 'look it up'. More sharing of knowledge needed, not lazy criticism.

@@akiiakilius3476So that seems to translate to ‘band cutting’, not too shocking for thin metal craft. But from there, all the Google hits are mostly for Norwegian heavy metal bands. It would be useful to have a link. I saw a lot of metal roofing in Iceland so dealing with blowing rain, snow, and ice requires some interesting detailing. Haven’t been to Norway,

@@MakerMaxCorbett my concern is the valley could be wider. Good roofers would shape the valley as a W, that is with a 1 " rib running up the center, six inches minimum of flat on either side and a quad rolled hem at the edges to provide a little bump. The real secret is insulation Get yourself a bale of Roxul and do an R-100 wrap around chimney and under cricket.

Through the roof was the worst caulk you couldve chosen for longevity and adhesion.

One recommendation I see so far. Would it be better to keep separation of untreated wood (or treated wood FTM) and brick? Paper or anything? That brick will be from the rain, but could contain some moisture. nice how you kept the valleys out from the chimney. Makes it more difficult, but effective. Looks really nice!

That’s why we have chimneys situated on the Ridge lol

gold job💯

[@craiglist308]

man what you did and the work it took to get there and all the tools put together to make it all and teh time spent... I admire that

[@MakerMaxCorbett]

Thanks. Top quality work. Better to put a few more hours in now then have water get in later.

[@stuart8219]

Lol all you have to do is flash it right … easy

[@andypeterk1720]

Good job. Thanks for sharing...putting my metal roof on this week. This helped me out.

[@MakerMaxCorbett]

Glad I gave you some ideas. I could not find much for a cricket.

[@victorpotts7244]

Thanks, I having one installed on a present metal roof. My question is, How do you divert water from over a doorway on a pre existing roof? I hate gutters and down spouts.

[@jonmiguel]

I'm years past being able to climb up and solve my own problems. Who am I to criticize? Looks clever, probably effective. I am a little worried about the tip of the saddle ridge overlapping the main ridge. Good luck.

[@MakerMaxCorbett]

It looks like water can get in, but the underneath is overlapped so it can't.

[@jorgev6077]

Looks good

[@craiglist308]

The work it took to do all of that and to make all the steps work together... thumbs up!!

[@MakerMaxCorbett]

Thanks. It was a lot of puzzle solving.

[@sdmairs2386]

I was hoping this video would cover how you fixed your step flashing to the chimney. You touched on the caulking but no mention of routing or the mortar between the bricks or how you tied the step flashing together. Were those screws anchored to the bricks?

[@georgedavis9943]

Top tier. Appreciate the pride you took in this. Researching crickets right now getting ready to fix a similar issue. Thank you for all the ideas!
