Out the front put a shed roof in front, about 2/3rds the way up the existing roof and box in the sides.

Best reception might be on the roof but they can cause leaks and also can have an electrical fire during a storm causing a fire and damage to your building.So I see on buildings where they might allow one installed on the ground but not the building and they have to get management approval.

If all roofs in your area are typically older then this one may be relatively "new".

I spoke with him and found he has put a new roof,carport roof, furnace, outside paint job,and two window units in.

Pardon the pun but prices are going through the roof down there --and relatively quickly!

This roof will deteriorate rapidly in heat and insurance will not pay for interior damage done by bad roof.

On top of yesterdays issues (cracked joists, leaky roof), after last nights downpour, today we can add leaking basement and flooded yard with serious drainage issues to the mix.

For instance if you need a new roof, we'd have pricing based upon a square price (100 sq ft area of roof) if you needed a new layer, an amount if you're doing a full tear off, replacing plywood sheathing, etc.  

The biggest problem is the roof which should be vented from the soffits to the ridge.
