I had one $180,000 rental when turned over had most windows broken, roof shingles damaged, the tenant rebuilt his harley on the living room floor, cigarette burns on the bathtub edges, used,diapers crammed down all the vents, holes kicked in the walls and doors. 

And even he said at that event that any agent's success in the business is not built upon the company they choose to hang their shingle with, but that agent's own efforts directly. 

I've now had shingles blow off roofs, pipes break, sumps malfunction, hail damage, fire, etc.

Metal roof vs shingle vs asphalt.

Shingles over existing roof 4.

That is usually the time the truck throws a rod, or even worse a few years ago 3 days after paying property taxes I went to pick up a load of almost 50 squares of shingles and the ball broke off the hitch of the brand new trailer I had borrowed from my friend. 

It was listed as homeowners insurance instead of Landlord and the underwriter cited misplaced shingles @Bob B.

Unfortunately my wife first came down with pesticide poisoning, then the shingles this past Xmas.

Find out what flashing they are using, what shingles they are using, how much they are charging a square, are they removing the old roof for you?

Some contractors are hesitant at first but when they realize we always have the materials on site when they need them then they relax and actually like working with us.I don't provide shingles to roofers, gutters obviously, and other similar items.
