  • Ensure that the boards have no splits or cracks in them.
  • Ensure that the plank protrudes about 6-8-inches past each jack (this is to ensure that the board will provide a non-wobbling and stable platform.

How To Use Roof Jacks

To use the jacks, you need to find a flat and clean part of your roof. Since most shingles could be worn out and may easily break, you will need to place your jacks in the fourth or fifth shingle course. You can easily and perfectly move onto the roof through the dead area with a jack roof coating.

After picking the part, you need to drive the nails, place the roof jacks to the initial jacks side, and leave about 4-feet in between jacks. Avoid overlapping the nails and test the jacks once you have fixed the planks or boards. The jacks are safe to use if they can support your weight, but you need to adjust the plank if it is wiggling.

Safety Tips For Using Roof Jacks

One of the most important things to remember when using a roof jack is how high off of the ground you actually are and whether or not theres anything nearby that could potentially fall onto your head if it were to slip out of your hands .

It might be a good idea to wear some sort of hard hat in order to ensure that youre safe from any potential hazards.

Also, its usually not recommended for someone who has never used one before to try lifting heavy objects on their own without another person there as backup support.

It might be best if the first time you use a roof jack is to bring something lightweight up onto the roof so that you can get a feel for how it works and learn what kinds of objects its best used to lift.

The last thing to keep in mind is safety while standing on top of your Roof jack. It might be better if someone else holds onto the handle just in case anything were to go wrong and you lose your balance.

If youre working with a partner, try not to move around too much while standing on top of the roof jack in case it throws off their own sense of stability and they need to take control.
