Sorry to hear about the damage, David. You should definitely check with the policy declaration paperwork (it would normally list hail/wind right on the first page) but it is customary in homeowners' insurance for hail and wind damage to have very high deductible, way higher than any other type of claim - about 2% of the property value is the norm. So, if you submitted 6,500 and got 1,395 then your deductible came out to be 6,500-1,395= $5,105. If your house is worth (or at least your policy is covering it up to) about $255,000 then the amount you got from the Ins. Co. sounds about right.
Like I said, be sure to check with the policy paperwork but don't be shocked if you see 2% or even 3% in some places down South. Perhaps it's even better to call the Ins. Co. - there are usually nice people on the phone that can walk you through. Additionally (although it would be too late for this particular claim but may help in the future) - you may be able to lower the overall coverage which will in turn lower the wind/hail deductible. If you haven't adjusted your policy in a couple of years, and property values in your area went down, there's no reason to pay for higher coverage than you need. It will lower both the premium as well as the deductibles that are calculated as percentages of the total coverage.
One parting note: in my dealings with bidding situations, we would normally throw out the lowest and the highest bids. You should even tell the contractors that this is what's going to happen. It is very much possible that the lowest bid is based in an erroneous assumptions about the conditions on the job or the customer's requirements (admittedly, done that myself more than once), and the highest bid is usually an indication of the fact that the contractor is simply too busy for you anyway. So, if you picked the lowest, you would end up paying more (sometimes way more) via change orders else the job won't get finished, and if you for whatever reason picked the highest, you would be paying a lot for very little attention to your job. So, that's why you need at least 4 quotes (3 is the bare minimum) if you wanted to be very careful and pick the absolute best contractor for the job.
