You are delicate with your bending and folding techniques. Very nice. With that said, silicone should not be the sole sealant for copper seams. Soldering allows expansion and contraction with a superior life span
Thank you for you comment! When using a ridge cap, it is important to fold back the counter flushing and caulk well. Installation also requires layers of high-performance underlayment. Pure silicone caulk is much more resistant than urethane-based one, and is often used in sheet metal work including copper. The corner ridge (or hip cap) is called "Hamaguri" in the traditional Japanese construction method. In the original construction method, both ends of the Hamaguri or the hip cap are also interlocked with the main body, but our corner ridges are designed to use caulking for better workability. Even with the traditional construction method, the hip caps may be where the leakage occurs so we recommend that you use a high-performance underlayment beneath them.
Thank you for your kind words! The tong/benders that we are using in the video are from a Japanese brand called MORIMITSU co. ltd. Hope you're able to find them!
We would also like to mention that all sheet metal tools we use are crafted in Japan. The curved scissors are called "Yanagiba" (柳刃). The scissors that look like clips are called "Tsukami". Both are essential tools for Japanese craftsman.
The tong is called "tsukami" in Japanese! We don't know of any online shops that ship internationally but Morimitsu is the most popular brand for tongs in Japan.
Thank you for your comment! Corner ridge is what we call "hamaguri" in traditional architecture. Traditionally, all four seams need to be locked in but this is extremely difficult to adjust and takes great care. Our roof shingles are improved from this beautiful traditional method, and made to be installed easier. In either method, though, this area needs some anti-rain measures such as doubling underlayment. Please let us know if we can answer any more questions! monji.morikunijapan.com/contact/
The curled tail ("hamaguri") is a traditional method that highlights the beauty of the curves. It is an advanced method, but because of how this small part needs to be locked from all four sides, there are many joints. This leads to higher risk of rain leakage. On the other hand, MONJI's method is much easier -- the sides do not need to be locked, and they just need to be caulked. It requires higher level of underlayment, aware of the risk higher than the traditional method. Thanks for watching!

Thank you for watching our video! When using a ridge cap, it is important to fold back the counter flushing and caulk well. Installation also requires layers of high-performance underlayment. Oil-based caulking will cause stains on the copper roof, so it is better to use pure silicone caulk. Pure silicone caulk is much more resistant than urethane-based one, and is often used in sheet metal work including copper.
Drives me crazy…. Why use galvanized screws with copper ???? The moment water comes in contact with zinc (galvanizing) and copper, you get galvanic corrosion which will eat right through the light gage copper.

Why could you not lock the curled tail on to the copper.

On the vertical seam you'd need a double lock, and this method looks better than that
hey mate, what brand nail bag/ tool belt are you using? i like it
We don't know the brand name of the tool belt. KNICKS and Makita are widely used among contractors in Japan.
where do you get the tools

Caulking on copper🤔...

Honestly pure silicone will likely outlast solder. It's not traditional, but I get why they're doing it.

Caulking🤔
Please see 04:59 for how to caulk the overlap. Detailed installation manual is also available at monji.morikunijapan.com
Why wouldn't you seam the copper on, then solder? Delicate work, but you lost me at using caulking on copper. Do better.
music is so annoying I would rather listen tools clacking
