The first thing that you need to do when installing roof jacks is to find a good area for them to be used. For example, a typical place to put the first roof jack would be somewhere around the fourth or fifth course. You can often use the dead area in conjunction with black jack roof coating in order to make the positioning of the jacks easier and more accurate for the work that you need to do later. Make sure that you drive the nails into the overlap area to hold the jack so that the nails are not exposed when all is said and done.

With that done, you should then position additional roof jacks on either side of the original jack with no more than a four foot distance between the different jacks. Once the positioning of the different jacks has been completed, you can place a board on the jacks. The idea is that the board will provide you with footing of a stable kind and thereby allow you to finish the roofing job a lot easier.

Once you have the board in place, you should find that standing up and holding your position has become a lot easier, even though nothing has actually changed in the slope angle of the roof. If this is not the case, then you should take a look at how you installed the jacks.

Once the project has been completed, all you have to do is remove the board and the jacks along with it. Since the nails were put into the overlapping dead area between the shingles, they should now be covered by the next row of shingles, meaning that a few taps with a hammer will drive them home completely and allow your roof to look perfectly normal to the naked eye.
