I thought a metal roof would be a permanent fix.

How long should it take one man to install about 70 feet of metal rain gutter 8' off the ground?

the bottom of a closet door chewed into splinters by another dog,  6. some idiot tenants who decided the crawlspace under the house made an excellent dog house (nothing like scooping dog poop out on your belly) and 7. much of the metal around an HVAC unit rusted out early by a male dog marking his territory there.Gail

Things that come to mind are bars around windows and a heavy metal security door over entrances.

Galvanic corrosion occurs wherever two different metals touch.

romex and plastic electric boxes ...I hope this is done to code. sure you dont need conduit and metal boxes there ? 

He said that those were cracks in the metal and that the furnace had to be shut down due to a poisoning danger.

Cops will do nothing, if they have what looks like a signed lease and they have children, you will have to evict them through the courts, I forgot what its called, but something remainder, that will take 90 days and you will have to pay court costs, I would do cash for keys, offer them 500 dollars to leave, and then put metal gates on the front and back door, so they need two sets of keys to get in, also get simplisafe and install.

Kenneth,My wife and I lived out in York Harbor for years, beautiful state.Try a plastic barrel that actually seals, I have seen them with an o ring, hinge and clamp.This may keep the moisture out better than a metal bucket.

@Chris BlackburnDoes this use metal for framing?
