The roof, a structure that shields your home from the weather, is made up of more than just shingles or tiles. A roof jack, or a pipe roof jack, is an essential but sometimes disregarded part of this system.
If you’ve ever wondered what a pipe roof jack is or how to install one, you’re in the right place. From the different types and purposes of roof jacks to the installation procedure, this all-inclusive blog post will take you through every aspect of roof jacks.
Note: There are two types of roof jacks in the roofing industry. Roof safety jacks are adjustable platforms used by roofers during construction. This blog post covers pipe roof jacks, which are found around the base of pipes and other roof penetrations.
What Is A Roof Jack?
Designed to protect vent pipes and roof penetrations, pipe roof jacks prevent water and debris from causing leaks or damage. Made from durable materials like metal or plastic, they form a watertight seal around pipes, reducing the risk of water damage and extending the roof’s lifespan.
Available in various sizes to fit different pipe diameters and roof pitches, they are both versatile and easy to install. Roof jacks also enhance energy efficiency by stopping air from leaving the attic through gaps around roof pipes.
- Leak Prevention: Roof jacks block water and debris, preventing leaks.
- Durability: They’re made to handle harsh weather.
- Versatility: Different sizes fit various pipes and roof pitches.
- Ease of Installation: Easy to install with no major roof changes.
- Stops Air Leaks: They enhance energy efficiency.
Now that you understand the purpose and benefits of roof jacks, let’s delve in further to understand what materials are used to make them.
What Materials Are Roof Jacks Made Of?
A variety of materials, chosen for their strength and resistance to inclement weather, are used to make roofing jacks. Some common types are:
- Aluminum
- Galvanized steel
- Plastic
- Copper
- Rubber
Along with different materials, there are also many kinds of pipe roof jacks available. Knowing these types will help you select the best one for your particular roofing requirements.
What Are The Different Types of Roof Jacks?
There are several types of roof jacks, each serving a specific purpose. Let’s break them down:
1. Standard Roof Jacks
These common roof components fit various pipe sizes and types, creating a protective barrier around pipes to block rainwater and debris. Made from durable materials like metal or high-quality plastic, they are easy to install and crucial for roofs with plumbing or ventilation pipes.
2. Gas Vent Roof Jacks
Made from heat-resistant materials, these jacks are installed around pipes for appliances like furnaces and water heaters. They ensure safe venting of gases and prevent leaks.
3. Boot Roof Jacks
These flexible jacks fit around pipes or vents, providing a snug seal. They handle variations in pipe size or roof pitch and are made from durable, weather-resistant materials like rubber or silicone.
4. Saddle Roof jacks
With a saddle-shaped profile, these jacks are used over the roof’s ridge or hip. They direct water away from the pipe and are effective on sloped roofs to prevent water accumulation.
5. Curb Roof Jacks
Used for raised installations, like HVAC units, these jacks elevate equipment above the roof surface for proper drainage. They provide a secure base that protects the equipment and ensures efficient operation.
Once you’ve selected the right type of roof jack for your home, the next step is installation. In the next section, we’ll go through the installation process.

Installation Steps
Step #1. Preparation
Before you begin roofing work, check the weather to ensure it’s clear—avoid working in rain or strong winds, which can make the roof slippery. Clear away any debris around the roof and gather all your tools so you don’t have to make multiple trips up and down the ladder.
Step #2. Access the Roof
Set up a stable ladder on a flat surface and make sure it’s secured to prevent it from slipping. Wear shoes with good grip to avoid slipping on the roof. Be mindful of your surroundings, especially any nearby electrical lines.
Step #3. Remove the Old Jack (if applicable)
If you’re replacing an old roofing jack, carefully lift the shingles around it to expose the jack. Use a utility knife to cut through any caulk or tar around it. Remove the nails holding the old jack in place, then gently pry it up without damaging the surrounding shingles.
Step #4. Measure the Hole
Measure the hole where the vent pipe comes through to make sure it fits the new pipe jack. The flange of the jack should extend beyond the hole to ensure a good seal.
Step #5. Position the Roof Jack
Place the new jack over the vent pipe, making sure it fits snugly around it. The flat base should sit firmly on the roof. For pipe jacks, ensure proper alignment to prevent leaks.
Step #6. Secure the Jack
Use roofing nails to secure the jack by driving them through the jack’s holes into the roof deck. Make sure the nails go deep enough to reach the framing beneath, as relying only on the deck might not be strong enough.
Step #7. Sealing
Apply tar or roofing sealant around the jack and nails to create a watertight seal. Cover all exposed areas generously to prevent water from getting through.
Step #8. Reposition the Shingles
Carefully move the shingles back around the jack, making sure they overlap the base to direct water away. If you removed any shingles to access the old jack, secure them back in place and align them properly.
Step #9. Final Inspection
After you’ve finished, check the area to make sure everything is secure and sealed correctly. Look for any gaps or loose shingles that could lead to leaks. Take a step back to ensure the jack is properly positioned and the shingles are aligned.
Just like any other roofing project, installing a roof jack is an intricate process. To get the best results for your roof jack installation project, contact a roofing professional.
Are Roof Jacks Suitable For Flat Roofs?
For flat roofs, especially those in areas with frequent rain, pipe roof jacks are essential. The minimal slope of flat roofs can lead to drainage challenges and water pooling. To address these issues, choose roof jacks designed for flat roofs, like curb roof jacks. Ensure the jacks are compatible with your roofing material and installed correctly to prevent leaks and structural problems. Considering the roof’s load and drainage requirements, and ensuring proper installation is essential for maintaining roof integrity.
