"In many cases the constants used by the program are pre-calculated and displayed in editable text boxes. If the user does not agree with the displayed constant, he can directly edit the value on the screen.
"The program addresses most of the structure types addressed in ASCE 7-98 as listed in ASCE 7 chapter 6.
"It is strongly recommended that the user be familiar with ASCE 7-98, Chapter 6 prior to using this program."

Most of the codes allow determination of loads in accordance with ASCE 7. Check the particular code to see which version of ASCE 7 is in effect at the time (could be ASCE 7-02 or 7-05...I don't know of any groups still using ASCE 7-98, though it is possible that they are...standards adoption lags behind code adoption which lags behind the state of the practice....)
Also as stated, many states have a separate code for residential, in particular single-family or two family dwellings. Though it probably isn't greatly different in the structural aspects, it can be.
NOW...if you've never done this before, I suggest you involve a senior level structural engineer to review your work or mentor you through the process. It is easy to screw it up, and if you're doing it for someone other than yourself, you can get into a bit of trouble for not doing the right thing.

As mentioned, the local building code will be the driver.
The AFPA also issued "Wind & Seismic", Special Design Provisions for Wind and Seismic" it is dated 2005/2006.
Good luck, sounds interesting.

This is awfully hard though unless you have the original plan. How would you know what hangers they used to hold down the roof? How about to hold down each end of the wall or at openings into the foundation?
Never, but never question engineer's judgement

How will you verify the strapping? Are you planning to look in the attic and verify gable bracing in sometimes inaccessible areas? How will you verify the nailing pattern of the sheathing? How will you verify the types of fasteners used? How will you know that strapping was properly nailed?
If tension rods were used in lieu of straps, how will you verify that bottom and intermediate plates and nuts are installed?
Since the house was built in 2000, do you know if deterioration due to water intrusion has occurred? Do you know if the sheathing has been compromised as a result?
A 130 mph wind is nothing to play with. I realize it's a small structure and its macro economic impact is not great; however, it is the protection for someone during a storm and if not, the structure should be there when they return.
Approach this with your eyes wide open.
