11 Step-by-step Guidelines on How to Install Valley on Metal Roof

Step 1: Gather Materials and Tools

The first step to installing Valley on your metal roof is to make sure you have all the necessary materials and tools. You will need:

• Valley Flashing (Pre-cut or Roll)
• Roofing Nails
• Roofing Cement or Adhesive
• Metal Snips
• Tape Measure
• Chalk Line
• Safety Gear (Gloves, Goggles, Etc.)

Step 2: Measure and Cut the Valley Flashing

Measure the length of the valley on your roof and cut a piece of valley flashing to that length using metal snips. Make sure to leave a few inches of overhang on either side for proper installation.

It’s always better to have more than less, so don’t be afraid to cut a longer piece. But remember, you can always trim off any excess later. You can also opt for pre-cut valley flashing, which is usually more costly but saves time.

Step 3: Preparing the Valley Flashing

If using a valley flashing roll, unroll it and lay it flat on a clean surface. You will need to bend it into shape according to your roof’s width. To do this, fold one edge over about an inch, then fold the other edge over that. This creates a “W” shape, which will sit perfectly on your roof’s valley. It’s important to pre-bend the valley flashing before installation to save time and ensure a smooth fit.

Step 4: Clean the Roof

Before installing anything, make sure your roof is clean and free of debris. Any dirt or debris can affect the installation process and damage the integrity of your metal roof. Use a broom or leaf blower to remove any loose debris or dirt. This is also a good time to check for any loose screws or nails on your roof that may need to be tightened.

Step 5: Position the Valley Flashing

Lay the valley flashing on the roof, ensuring that it sits flat and snugly in the valley. It’s crucial to make sure that there are no gaps or spaces between the flashing and the metal roof. It’s also essential to double-check that you have enough overhangs on either side. Although valley flashing is typically nailed to the roof, it’s also a good idea to use roofing adhesive for extra reinforcement.

Step 6: Nail the Valley Flashing

Using roofing nails, secure the valley flashing in place. It’s recommended to nail every six inches or so along both edges of the flashing. Make sure that the nails are driven into the metal roof and not just the flashing to ensure a secure hold. Otherwise, the flashing may come loose in severe weather conditions. It’s also crucial to use the correct size nails for your metal roof. Consult with a professional or do some research to determine the appropriate size.

Step 7: Apply Roofing Cement or Adhesive

Using a putty knife or caulk gun, apply roofing cement or adhesive along both edges of the valley flashing. This will help create a watertight seal and further secure the flashing to your metal roof. Make sure to cover all nail heads as well. This step is vital to prevent any water from seeping underneath the flashing and into your home.

Step 8: Repeat Steps for Additional Valleys

If your metal roof has multiple valleys, repeat the previous steps for each one. Make sure to measure and cut each valley flashing piece individually as they may vary in length or width. It’s also crucial to overlap the valley flashing pieces to ensure complete coverage and protection against water damage. It’s better to have a slight overlap than no overlap at all.

Step 9: Trim Excess Flashing

After installing all the valley flashing, use metal snips to trim off any excess from the overhang. Make sure to wear safety gear while doing this as sharp edges may be present. It’s essential to have a clean and neat finish for aesthetic purposes, but more importantly, to prevent any damage to the roof or potential hazards. But remember, it’s always better to have more than less, so don’t trim too much off!

Step 10: Inspect and Clean Up

Once you have trimmed off the excess flashing, take a moment to inspect your work. Make sure everything is secure, and there are no gaps or spaces between the flashing and the roof. Use roofing cement or adhesive as needed for touch-ups. Finally, clean up any remaining debris or materials from the site and dispose of them properly.

Step 11: Enjoy Your Newly Installed Valley!

Congratulations, you have successfully installed Valley on your metal roof! Take a step back and admire your hard work. Not only does it add an aesthetic touch to your home’s exterior, but it also provides necessary protection against water damage. If you follow these steps on how to install valley on metal roof carefully, your valley should last for many years to come. But don’t forget to regularly inspect and maintain your metal roof and flashing to ensure its longevity.

Do You Need  to Hire a Professional?

While it is possible to install valley flashing on a metal roof yourself, it’s always recommended to hire a professional roofing contractor for any major installation or repair work.

They have the knowledge, expertise, and specialized tools to ensure that the job is done correctly and efficiently. Plus, they often offer warranties on their work, providing you with additional peace of mind. If you are unsure about DIY installation, don’t hesitate to reach out to a professional for assistance. 

So, if you want your valley flashing and metal roof to last for years to come, it’s best to leave the installation in the hands of professionals who know what they’re doing. It may cost a bit more upfront, but it can save you from potential problems and expenses in the long run.
