What Is a Pipe Jack on a Roof

You may have recognized the pipes sticking out of your roof before. They are called plumbing vents and apparently are one of the most important pipes in the house. They consist of vertical pipes connected to the drain lines, and supposedly, no water runs inside them.

The pipes release unpleasant odors and gas inside the building instead of removing water and waste from septic tanks or sewers as drainpipes do.

The roof jack system seals roof penetrations, which is sometimes called roof flashing. Unfortunately, contractors often install these improperly, particularly on composition shingle roofs, which can increase the likelihood of water infiltrating the roofing system.

When the flashing is installed properly, it should completely cover the lower edge of the skirt. This allows the shingles to cover the nails and roofing adhesive and secure the skirt, offering the best protection from leaking water.

Personal Experience

In my years of experience as a roofing professional, I’ve seen many cases where improper installation of roof jacks led to severe water damage. For instance, during a project in Dayton, OH, we had to replace an entire roof section because the homeowner used cheap rubber pipe jacks that deteriorated quickly, leading to significant leaks. Investing in quality materials and proper installation is essential to prevent such issues.

How to Install a Roof Jack

After learning about a roof jack, you might be curious about how to install it. You can either get a homemade or a store-bought version. The installation process is relatively easy and quick. Below is a step-by-step tutorial to guide you through the process.

Climb up to the roof area

You must climb onto the roof to install the new roof jack, and you will need a ladder to do it. Ensure the ladder is safe, secure, and distant from electrical lines. If the repairing work happens to be near electrical lines, the best and safest way to complete it is to call a professional.

Loosen the shingles

Using a knife, loosen the shingles installed on the side and top of the existing roof jack. This should be easy, as the knife should slide underneath the shingles. You also have to remove the roofing nails under the shingles.

Install the flashing

Lift off the existing to remove it. At best, you’ll only need to remove several nails from the pipe. Then, move the new roof jack above the plumbing vent under the shingles. Secure it to the roof by using nails on every corner. Then, put back the shingles in their place.

If you understand what a roof jack is and the whole installation process, it is not very difficult. However, it is still necessary to take precautions for safety and call a professional if needed.
