You could try alternatives like second skin or quiet coat which go for much less then dynomat and apparently work better. I know the second skin guy if you need to get in touch with him.
As for sprays, they are not quite as effective as dynamat or it's alternatives. Mostly they are used to get into tough to reach areas such as behind the door panels. A combination of dynamat (or alternative) with spray will give you your best deadening.
Oh and if you can get in contact with a roofer then by all means use that stuff! Definetly the best way to go!
