If you are planning to fix or remodel your roof, don’t forget that before you even start your project, safety comes first, and you’d better install those roof jacks. These are steel anchors that fasten to your roof and hold planks of wood for you to walk on. Installing them can be quite tricky if you’re a beginner, and you might end up destroying your roof, doing more harm than good. With these instructions, you will soon be a pro at installing roof jacks and get your roof done in no time.

Step 1: Prepping Installation

Carefully place a ladder by the side of the roof and make sure that it is stable and secure. Slowly go up the ladder, to check if you are able to reach the sloping portion of the roof.

Step 2: Determine Placement

Determine the best place to fasten your first roof jack. It is usually placed on the fourth or fifth level of the rows of shingles, depending on how comfortable you feel on either. Others often prefer to place the first one at the edge of the roof. It really depends on who is going to be fixing the roof.

Step 3: Placing the First Roof Jack

Make sure that the diagonal holes on the jack are at the top part of the shingle. Drive a nail in each slot, and pound it down in such a way that it is level with the metal of the jack. Make sure that you don’t push it all the way inside your roof since you might damage it. Next, drive a nail at the bottom part of the jack, in order to secure it on both ends. Now you’ve installed the first one.

Step 4: Repeat Step 3

Do step 3 a couple more times, and keep placing the jacks at secure points on the roof. Make sure that the roof jacks are evenly spaced from each other, about 2 feet or so, and from the edge of the roof. Don’t make them too far apart, so as not to compromise support.

Step 5: Placing the Planks

Once you have placed a couple of jacks on the roof, you can now put wooden boards between them, which you will be able to stand on while accomplishing your roofing project.

Step 6: Add More Jacks

Once you have worked on an area of your roof as much as needed, you may add more roof jacks, in order to access the higher parts of your roof, or you can remove and reset the ones you won't need again. It actually helps if you have more wooden boards already set up, so you can move more freely and add more jacks in a horizontal manner.

Step 7: Remove the Jacks

Once you’ve finished your project, remove the jacks by hammering them upward until they are free from the nails. The roof jacks should slide out, and as they are freed, the nails should be hidden by the shingles, and you don’t need to take them out.
