Hi, everyone; got a minute??
I need to replace roof sheathing damaged during hurricane Ivan.
A heavy branch blew down across our power line, which heaved on the
riser pipe  like a lever. That ripped the power meter away from the
wall and enlarged the hole around the riser. Electrical repairs were
made long ago [$750], but the hole dribbles water into the soffits every
time it rains.
I'm willing to try the repair myself if I could get your advice on...
a) separating and removing the shingles
b) cutting out and replacing as small a section of the roof as
c) the tools / materials necessary for the job
d) how not to make things worse
The old shingles are stuck together. Would a heat gun help?
I'll need to buy something to cut across two rafters, but what --
jigsaw, sabersaw, rotozip?
How do you get out the nails without tearing up more shingles?
I'll probably have to buy way more shingles, roofing tar, and tarpaper
than needed for the repair.
Sound right? Thanks for your help, and I'll read your answers right
 The riser conducts the line from the electrical meter up (in my case
right through the eave) to a safe height above the ground
