One of the factors used to designate compressor power is motor horsepower. However, this isn't the best indicator. You really need to know the amount of air the compressor can deliver at a specific pressure.
The rate at which a compressor can deliver a volume of air is noted in cubic feet per minute (cfm). Because atmospheric pressure plays a role in how fast air moves into the cylinder, cfm will vary with atmospheric pressure. It also varies with the temperature and humidity of the air. To set an even playing field, makers calculate standard cubic feet per minute (scfm) as cfm at sea level with 68 degrees F air at 36% relative humidity. Scfm ratings are given at a specific pressure–3.0 scfm at 90 psi, for example. If you reduce pressure, scfm goes up, and vice versa.
You also may run across a rating called displacement cfm. This figure is the product of cylinder displacement and motor rpm. In comparison with scfm, it provides an index of compressor pump efficiency.
The cfm and psi ratings are important because they indicate the tools that a particular compressor can drive. When choosing a compressor, make sure it can supply the amount of air and the pressure that your tools need.

Need to know how to read the roof pitch on my
The pitch of the roof is described as the vertical rise of the roof divided by the horizontal span of the roof. The pitch of the roof is known as slope, and this happens to be a tangent function. When pitches are kept below 3.5, they are considered as low pitch, and when the pitch is kept from 3.5 to 7.5, it is considered as medium pitch anything above than 7.5 is considered to be a steep pitch. Depending on your requirement and style of construction you can decide the pitch of your roof. Click on

Any installation specs on the best way to install
This is just generic instructions just to give you an idea of placement and mounting. I am not sure if your vise turns or not and that would be a big factor also. It depends on where you want it, if anything is close that will interfere with the vise or whatever you have in the vise. Depends how thick the spot is where you want to mount it. If the place is not very thick, use bolt and heavy washer on top of the vise and a heavy washer, a lock washer and nut on bottom. In place of the lock washer and nut, you could use locknut. If the bench where you want to mount is too thick for bolts, use at least 2" lag bolts with heavy washers with the lag bolts as big as the vise holes will accept. You will need the vise as close to the edge without it hanging over the edge of the bench. This is so you will be able to open and close the vise without obstruction. If placement of the vise isn't a big deal, the center edge of the bench would be great although I always mount mine on one end of the bench because of better movement of the part in the vise. Goodluck.
