Roof flashing is one of the most important aspects of installing a roof. The flashing is necessary because of the added protection if offers your home. Flashing refers to a sheet of metal installed in the area surrounding fluepipes and sewer vents. It is installed in the parts of shingled roofline where there is a break too. Flashing is installed around the edge of the roof as well. Flashing a pipe on a high-angled roof is not an easy project. The flashing and the piping, just like all other aspects of the roof, need two things; regular inspection and proper installation.
The pipe that needs flashing is often galvanized metal. Many self-taught individuals prefer using aluminum flashing, which is just as effective and bends easily. Flashing the pipe mostly happens to make the roof as leak-resistant as possible. Periodically, the nails fastening the flashing might loosen. In addition to this, the flashing materials might pull away right at the seams and joins; thereby requiring some maintenance. This is when you will have to climb the ladder and make your way to the roof to fix the problem.
Be Ready with the Right Tools
First, you need the following tools to flash properly:
- Flashing materials
- Metal break tool
- Tin snips
- Preformed flashing
- Roofing cement glue
- Silicone caulking
- Galvanized roofing nails
When flashing a pipe on high-angled roofs, you need to place the upper portion carefully beneath the shingles. While doing this, allow the lower part to be over the shingles. The lower portion should be exposed too. Next, lift the shingles that are just around the vents. Afterward, slide the upper part of the vent flashing beneath the shingles. The task would be incomplete if you have not cut the right size of membrane material. This material is for sealing the area lying between the roof and vent flashing. Do not forget that the vent needs an opening too.
Adhere to Instructions
Remember to apply a thin silicone bead near the pipe’s opening. Once done, place the membrane you previously cut in place. After that, place the vent flashing over the membrane. If you do everything well and as per instructions, you will notice that the metal flashing overlaps the material. If it is the other way round, you should redo the steps you failed to observe. The base of the pipe should be nailed in place using the hammer and galvanized roofing nails. At this stage, the shingles are on top of the vent flashing’s upper portion.
Stick to the Appropriate Distances and Measurements
None of the work you did above will produce the desired results if you fail to observe a few important pointers. First, ascertain that the shingle row fits perfectly around the lower portions of the pipe. Next, confirm that you slid the pipe flashing on top of the pipe. Measure the distance to ascertain it extends not more or less than 4 inches just below the pipe. Above the pipe, the distance should not be more or less than 8 inches. The distance to the left and right should be around 6 inches.
If you follow the instructions published here, your project should end up fine. If not, you ought to be ready and set some money aside for redoing the work or fixing the mess you create. Do not forget the purpose of proper pipe flashing; to provide the roof with adequate covering and protection. Do this well, so that your roof lasts a long time before it begins leaking. The entire structural stability of your roof – and the home – depends on your attentiveness to detail while flashing a pipe on a high-angled roof.
