Your ducts and A-coil may be the problem.

From a financial standpoint, I would agree with Jon's post about having your dollars in something that would hedge inflation, usually hard assets such as precious metals, real estate, and even collectibles like art, comic books etc (anyone see in the news about that Action Comics #1 currently bid up to about $230k).

The problem is the house was built in the 50s and have a metal tray around the window.

So precious metals are risky even when they seem like a no brainer.

(stocks, cfd's, metals, currency, oil, whatever )always looking for interesting info

The tub is old and metal with the white coating on it that is stained.

The slope is not great enough for metal or any shingle product.

I couldnt mop tar,,,no equipment for it,,,but I could shingle.Standing seam metal would be a great product for changing from flat to pitched.Minimum pitch here 4 /12 5 and 6 /12 even better for high rainfall/snow load areas,,,costs very little more.walking on the frozen roof can damage it also,,as well as scoop dings.

DO NOT HANG A FAN FROM A PLASTIC j-box, only a metal one.

Copper and brass are among the scrap metals that these people go after.
