I am building a block storage/shop building. I want to install a roll-up, garage-type door in one end. How do I measure for it and how do I need to do the header? I want the door to be 9 feet wide X 7 feet high.

The rough opening for the roll-up door is 9 feet wide and 7 feet high. Being block, you don't need a header. Just reinforce the rows of blocks across the top, and support them thoroughly (With cripples) until the mortar cures (2 to 3 days)

Measuring for garage door

A typical residential door will measure 9 x 7. I recommend wrapping the interior of the opening with 2 x 6's. This will make it easy to install and finish if your are finishing the interior of the garage and allow for the the perimiter stop mold for the door to be installed also, necessary for sealing the door. Also a verticle pad above the head for the spring. Not sure of the type of brick. I usually set these with sleave anchores set flush. The standard Headroom requirement is 16" for torsion springs and a operator. The interior wrap will look like a H with a center spring pad to keep all the door on the same plane. Smaller headroom configurations are possible but you will need to talk to the door installer/supplier. Beware that some manufacturers say they can install them in 3.5 inches but the door/operator will sit in the opening and if the 7 ft clearance is needed this might not be accepable. Also the headroom usually needs to extend 6 inches on each side plus 2 -3 feet x the door height depending on the operator. This is general and they can be shoe horned in. I cannot say without looking at it.
