In the US, most roofs are made of asphalt, which needs to be replaced every 20 to 30 years. However, you can make your asphalt roof last longer by regularly inspecting and maintaining it. One of the key aspects of this is making sure that your pipe flashings are in good condition.
Pipe flashings are the metal or plastic pieces that seal around your pipes where they come through the roof. They’re essential because they prevent water from seeping around the lines and causing damage to your roof or home.
In this blog post, we’ll discuss what pipe flashing is, where it’s used, and how to keep it in good condition. We’ll also cover some things not to do when installing or maintaining pipe flashings.
So read on to get well acquainted with this vital topic of transition metal in your roof.
What Is Pipe Flashing & Why Does It Matter?
Pipe flashing is a type of roofing material used to seal around pipes that penetrate the roof. Pipe flashings are installed over the pipe and under the shingles or other roofing material.
The flashing has a hole in the center that fits snugly around the pipe. This creates a watertight seal that prevents water from leaking into the house through the pipe.
Pipe flashings are important because they prevent water damage to your home. Water can cause wood rot, mold growth, and structural damage. By sealing around pipes with pipe flashings, you can protect your home from these types of problems.
Moreover, pipe flashings add an extra layer of protection against wind and debris. If a tree branch falls on your roof, for example, the pipe flashing will help to prevent water from leaking into the home through the hole left by the department.
How to Maintain Pipe Flashing?
Pipe flashing is made of metal, so it can last for many years if it’s properly maintained. The best way to keep pipe flashing is to have it inspected every year by a professional roofer.
During an inspection, the roofer will check for any signs of wear or damage. They will also ensure that the flashings are still sealed around the pipes and that there are no gaps or openings.
If you live in an area with severe weather conditions, you may need to have your pipe flashings inspected more often.
For example, if you live in an area that gets a lot of snow, the weight of the snow can damage pipe flashings. If you live in an area that gets high winds, the wind can loosen the flashings and cause them to come off of the pipes.
In general, it’s a good idea to have your pipe flashings inspected whenever your roof is inspected. This way, you can catch any problems early and prevent major damage to your home.

What You Should Never Do With Pipe Flashing
When it comes to ongoing care for your roof’s pipe flashing, there are several things you need to remember when you conduct any care or maintenance work.
- Never paint pipe flashings to match the roof. The paint will chip and, over time will make the flashing look worse.
- It is not recommended to use an inferior material that won’t last as long as aluminum, copper, or steel. Asphalt, rubber, and vinyl are all less durable than aluminum, copper, or steel.
- Do not forget to install pipe flashings with sealant. Sealant helps to prevent water from entering your home through the gaps around the pipe.
- Never hire a roofing contractor who doesn’t have experience with pipe flashings. Make sure your roofer is familiar with the installation and repair of pipe flashings.
- Never neglect to inspect your pipe flashings every year. Pipe flashing can become damaged over time and needs to be repaired or replaced as necessary.
