box gutter rebuild

Just purchased a large, 110 year old home, that has had the copper box gutters covered over & aluminum K gutters installed.
Due to the mediocre job that was done by the "professional" roofer, I may remove the coverings, & build in new box gutters.

I own a 10 ft brake, scaffolding, etc. Is there a reason why aluminum cannot be used for the construction?
What manner of joining sections would be successful? Would rivets & gutter caulk buckle & let loose due to thermal expansion? Longest strait run is 45ft.

Would rubber be a better choice re longevity, even though I would contract the job out?

Thanks

 

Its more in what you want to do. What is the copper like now. We used to always patch them up with copper and solder it in. If it was good up under the roof you could brake up a U out of copper to fit , solder and rivet it in. They have the pop rivet in copper.I would pull that K is it, gutter, the only one I know is OG .

Now on you last point. When a box gutter was in and made out of Galv sheet metal. if real bad yes we would tar them. Then lay a mesh cloth in this and tar over that. it would last for years.

My .02 cents ED

 

Thanks Ed,
We'll get the box gutters exposed & see if they are worth repairing.
It may be a while until we get to the task, as the interior mechanicals are in dire straits, & the wife says no-no to a porta-potty.
