What is a Roofing Jack? (How to Install it and Use It)

There’s a lot to know about roof jacks, but don’t worry: we’ve got you covered. Today, we’ll be discussing the ins and outs of roof jacks, including how to install them, use them for maintenance, and what you should look for in a good roof jack.

What is a roofing jack?

A roofing jack, also known as a roofing bracket, is a device used in roofing construction to provide a platform for workers to stand on and work from. It’s usually made of metal and is designed to attach to the roof decking or trusses.

Roofing jacks are used to give workers a stable place to stand while putting up or fixing roofing materials.

They are designed to be adjustable in height so that they can be set at the appropriate level for the job at hand. They also typically have a bracket or hook at the top that can support a plank or board, which provides a working surface for the workers.

You can also use them with safety harnesses and other safety gear to make sure that roofers have a safe place to work.

Roofing jacks are usually not permanent, and once the job is done, they are often removed.

What is the main purpose of a roofing jack?

The main purpose of a roofing jack, also known as a roofing bracket, is to provide a safe and stable platform for workers to stand on while working on a roof.

Roofing jacks allow workers to move safely and efficiently along the roof surface while installing or repairing roofing materials without the risk of slipping or falling.

The height of the jacks can be changed, so workers can set them to the right height for the job at hand. They would usually have a bracket or hook at the top that could support a plank or board, providing a sturdy working surface.

Is a roof jack necessary?

Yes, a roof jack, also known as a roofing bracket, is necessary for safe and efficient work on a roof if it’s really steep. 

Roofing jacks are an important safety feature in roofing construction because they give workers a stable place to stand while putting up or fixing roofing materials and keep them from slipping or falling off the roof.

While it is possible to perform roofing work without a roof jack, it is not recommended if you’re inexperienced or if the roof is really hipped, as it can be dangerous and increase the risk of accidents and injuries.

Working on a roof without a stable platform, such as a roof jack and plank or board, can lead to workers slipping or losing their balance, resulting in falls from a significant height

Using a roof jack and a plank or board creates a level and stable surface for workers to work on.

What are the benefits of using roofing jacks? (also include unique benefits)

  • Improved safety: Roofing jacks provide a stable and level platform for workers to stand on, reducing the risk of falls and accidents while working on the roof. They also provide support for planks or boards, which further improves worker safety by providing a sturdy working surface.
  • Easier installation: Roofing jacks help make the installation of roofing materials easier and more efficient. By providing a stable platform to work from, workers can move more easily and quickly across the roof, accessing all areas that need work.
  • Reduced risk of injury: Roofing jacks can help reduce the risk of injuries from lifting heavy objects. By providing a stable and level surface to work from, workers can position themselves properly and lift materials with less strain on their back and other muscles.
  • Versatility: Roofing jacks are versatile and can be used for a variety of roofing applications, such as installation, repair, and maintenance. They can be adjusted to different heights to accommodate different roof pitches and can be easily moved to different areas of the roof as needed.
  • Reduced damage to roofing materials: Using roofing jacks can help reduce damage to roofing materials during installation or repair. By providing a stable platform, workers are less likely to accidentally damage roofing materials while walking or working on the roof.

What are the disadvantages of having a roof jack?

  • Cost: Roofing jacks can be relatively expensive, especially if a large number of them are needed for a job. The cost of renting or purchasing the jacks, as well as the additional materials needed to use them, can add up quickly.
  • Additional setup time: Using roofing jacks can require additional setup time compared to other roofing methods, such as using ladders or working directly on the roof. The jacks need to be properly installed and adjusted, and planks or boards need to be placed on top to create a stable working surface.
  • Limited access: Roofing jacks may not be suitable for all roof types or configurations. Depending on the slope, shape, or height of the roof, it may be difficult to install roofing jacks or use them effectively, limiting access to certain areas of the roof.
  • Potential for damage: While roofing jacks can help reduce damage to roofing materials, improper installation or use can actually cause damage to the roof. If the jacks are not properly installed or adjusted, they can cause dents or punctures in the roof surface.
  • Safety risks: While roofing jacks can improve safety when used correctly, they can also pose safety risks if used improperly. Workers need to be properly trained on the use of the jacks and other safety equipment, such as safety harnesses, to reduce the risk of accidents or injuries.

When do you need a roof jack?

Some common roofing tasks that may require the use of roofing jacks include the following:

  • Primarily installed for roofs that are completely hipped
  • Installing or repairing shingles or other roofing materials
  • Applying roof coatings or sealants
  • Cleaning gutters or performing other maintenance tasks
  • Inspecting the roof for damage or leaks
  • Installing or repairing flashing or ventilation systems

Can you install a roof jack yourself?

Installing a roof jack requires knowledge of roofing and safety procedures. If you have never worked on a roof or in a high place before, it is best to hire a professional to put the roof jack in for you.

Whether you should install a roof jack yourself or not depends on things like your experience, how comfortable you are with working at heights, and how hard the job is.

While it may be possible to save money by doing it yourself, a mistake during installation could result in costly repairs or void your roof’s warranty.

When you try to install a roof jack on your own, you may need to make sure that the installation is watertight.

If the roof jack is not properly sealed, it can allow water to leak into your home, potentially causing damage to the roof, ceiling, and walls.

Professional roofers have the experience and skills needed to make sure the installation is watertight. If you’re not sure you can properly seal the roof jack, it’s best to hire a professional.

How do I install a roofing jack?

If you’re not experienced in this, please get the help of a professional. The following instructions are for educational purposes only.

  1. To install a roofing jack, start by selecting a suitable location on the roof and lifting up the shingle row to expose the installation area.
  2. Place the adjustable roof bracket under the shingle, ensuring it is securely positioned.
  3. Identify the studs underneath the roof.
  4. Next, use the appropriate nails to fasten the brackets to the studs or truss in the roof. Usually, three nails per bracket are enough, but this may vary depending on the specific jack and roof design.
  5. Once you have secured the brackets on both sides, place your wooden plank on top of the brackets and nail it securely to the plank holder of the bracket.
  6. Make sure the board is level and stable before stepping on it to begin working.
  7. Finally, double-check the stability of the roofing jack to avoid any accidents or mishaps.

How much does a roof jack cost to install?

Roof jacks can be purchased for about $10 to $15 per bracket. Some of the more expensive ones can cost as much as $30 each.

How long do roof jacks last?

A well-maintained roof jack can last anywhere from 5 to 7 years.

But roof jacks aren’t permanent, so they should be taken off when the job is done.

In fact, several people have tried leaving their roof jacks on their roofs after finishing jobs, and after a few years, the roof jacks would end up damaged or loose from the weather.

My advice is to just remove them once you’re done with them.

4 different types of roofing jacks

  • Adjustable roof bracket: These are versatile roof jacks that can be adjusted to fit different roof pitches. They are typically made of metal and can be easily installed and removed.
  • Fixed roof bracket: These are non-adjustable roof jacks that are designed to be installed permanently on the roof. They are available in a range of sizes and shapes to accommodate different roof types.
  • Metal roof bracket: These are roof jacks specifically designed for metal roofs. They are typically made of galvanized steel or aluminum and are rust-resistant.
  • Wood roof bracket: These are roof jacks made of wood that are suitable for use with wood or asphalt shingle roofs. They are typically made of durable, pressure-treated wood to withstand the elements.

Where do you place a roof jack?

Roof jacks are placed along the roof’s eaves to give roofing contractors a place to stand while they work on the roof.

They should be evenly spaced every 6 to 8 feet across the roof, and they should be attached to strong framing members like rafters or trusses.

You also have to locate the studs or trusses on the roof and make sure you nail the brackets in under the shingles above them to avoid exposing the nailed area to leaks.

Type of nails for roof jack installation

The type of nails used for roofing jack installation will depend on the material and thickness of the roof and the specific requirements of the manufacturer’s instructions.

Roofing nails with a length of at least 2 1/2 inches (up to 3 1/2 inches) and a shank diameter of 11 gauge or larger are suitable for most roofing materials.

These 8d (and 16d nails, respectively) can be used to drive through the sheath and into the frame for your roof jacks.

The head of the nails should be large enough to prevent the nail from pulling through the roofing material and the roof jack.

Safety precautions when installing a roofing jack

  • Regular roofing nails are too short: Regular roofing nails may not be long enough to properly secure the roofing jack, so it’s important to use longer nails or screws as specified by the manufacturer’s instructions to ensure a secure installation.
  • Roofing nails are usually not wide enough: The shank diameter of roofing nails may not be wide enough for the installation of roofing jacks, so it’s important to use nails or screws with an appropriate diameter to ensure a secure and stable installation.
  • Roofing nail heads can easily break off: The heads of roofing nails can easily break off during installation, which can compromise the stability of the roofing jack. Using nails or screws with strong heads can prevent this issue and ensure a secure installation.
  • Avoid installing during bad weather: It’s important to avoid installing roofing jacks during bad weather conditions, such as rain, snow, or high winds, which can make the roof slippery and increase the risk of falls and accidents.
  • Don’t install them on weak boards that can split: Installing roofing jacks on weak or damaged boards can cause them to split or break, which can compromise the stability of the installation.

How to remove roof jacks

To remove roof jacks, first, remove the screws that secure the standing planks. Then, look under the shingle for the bracket and wiggle it to loosen it from the nails.

 As long as the nails are located underneath the shingles above them, go ahead and pound the nails in and leave them in place. 

Finally, lay the shingle back down to cover the area where the roof jack nails were located. The shingles above should completely lay on top of the nailed areas to prevent water from coming in.
