How to Jack Up a Roof

This blog post will discuss what tools are needed, how high jacking should be done, and some general tips on getting started. The first step is determining where the support beams are located on top of the framework. So, this article is for you. You will learn how to jack up a roof with just one simple trick! 

Step by Step Guide on How to Jack Up a Roof

Step One: Make Sure You Have a Good Base to Work From

Jacking up the roof is generally done when the frame of the house has been damaged. To start, measure where your jacks need to be to raise the structure. Now, put your jacks on top of these beams carefully so that you don’t damage them. Make sure they are centered and straight with your beam.

Put The Jacks On Top Of These Beams Carefully

Step Two: Get Your Jacks Set in Place and Hooked Up to the Beams

Ensure that there is nothing under the plates of where your jacks are right now, or you will have a difficult time when it is time to use them. Once everything is ready for action, put wood blocks under the jacks so that when they start to lift, they don’t damage your roof.

If you have a flat roof, just add more jacks in a pattern that is not too far from each other. You want the structure to have even weight on all sides. If there are triangles or patterns in between your jacks, there is a good chance that they will slip or cause more tension on one side.

Step Three: Begin to Raise Your Roof.

After you have the jacks set up and in place, it is time to start lifting. Then, when you feel more confident, you can remove the wood block safety and start cranking up the roof and using your body weight to keep it steady.

Ensure that you have a good set of gloves on so that your hands don’t slip and cause injury. After you have your roof sufficiently raised, the next thing to do is straighten out the frame to level with other houses. Next, use a pry bar to bend down any beams sticking up or pressed into another beam.

Step Four: Repair Your Roof or Simply Make It Safe

To fix your roof, you will need to use shingles and nails in order to get either a temporary or permanent roof over the top of the frame. This is best done by laying down tarps under your work to catch any shingles that fall after you start using them.

After the frame is fixed, it is time to send your jacks back where they came from and lower the roof back down to their original position. Make sure to take apart your jacks and store them safely to be reused another day.

Step Five: Make Sure That the Jacks Are Safe to Use

After you have finished your project, make sure to get rid of any woodblocks and other safety measures used. If you still feel uncomfortable with using these tools after they have been checked for safety, it might be best only to use them under the guidance of a professional.

Once everything is good to go, store the jacks in an area that is safe and dry. You don’t want them to get rusty or broken so that they are unusable the next time you have a project to do. And there you go! These previous steps will work for any size roof, so whether your house is a tiny bungalow or a massive mansion, these tips will help you get started with what you need to do to lift your roof and make it safe from the elements.

Is It Normal for a Roof To Sag?

Before you can jack up a roof, the first thing you need to be sure of is that it’s sagging. If there isn’t any noticeable bowing when walking on your roof, then all you have is a possible ceiling leak from somewhere in your home or around your house.

What Is Causing Your Roof to Sag?

There are a few reasons that could be causing your roof to sag. First, if you have asphalt shingles on your roof, their weight over time could cause it to sag due to their lightweight. Second, if you have metal panels on your roof, then they will cause sagging as well.

These are just two examples of what could be causing your roof to sag, but you will likely be able to figure out the problem once you get up there and examine it. For example, if your roof is flat with a concrete smooth surface, you most likely have a structural issue.

Can You Raise the Roof of a House?

A small shed or porch can be raised by lifting the roof, usually with a jack. To raise the roof of a house, a series of supports are built and connected to the rafters. The structure is then lifted to place it on top of the support system and create an open space under the rafters.

A Small Shed or Porch


If you want to know how to jack up a roof, here are some helpful tips. First of all, the first thing you’ll need is a good set of jacks, and they should be positioned at each corner near where your rafters meet your trusses or purlins. Next, always make sure that the hydraulic cylinder on end is in contact with as much surface area as possible for maximum stability before proceeding.

Next, if there aren’t any other structures (like an overhang) blocking access directly under one side of the building, then position two jacks along that wall and use them to lift it off the ground by about four inches.
