How to Install a Metal Roof to an Asphalt Roof Valley

There are two common methods for installing a metal roof to an asphalt roof Valley: weaving and open cut. Although both methods are visually appealing, there are a few differences between them. Open cut is considered the most aesthetic and woven valleys are more visually appealing. If you’re planning to use the open cut method, be sure to take accurate measurements to ensure that you buy enough material. And if you have a valley with a steep pitch, you’ll have to stake your new shingle or roofing material accordingly.

Nailed Metal Flashing

Before laying down the metal Asphalt Roof Valley sheet, you should remove the shingles. Then, you can install the gutters. Then, you can place the metal roof edge. You can pull jacks to secure it to the roof deck. Once it’s nailed in place, you should use roofing nails to nail the metal flashing to the shingles. Unlike the shingle, which will expand and contract with changes in temperature, nailed metal flashing will not move at all.

Install First Piece

The next step is to cut the metal roofing panel. You can cut the panel by folding it and attaching it with eave clips. Then, fold the eave clip over the Asphalt Roof Valley, and cut it along the drip edge metal. Then, install a synthetic or felt paper underlayment. You can also install the first piece of valley flashing after the synthetic underlayment.

Water Shield

Once the metal flashing is installed, it’s time to apply the metal flashing. Remember to use roofing cement and nail it to the roof deck. Then, seal the entire area by applying roofing cement to the edge. After the flashing is in place, you can apply the metal underlayment. The underlayment should not be visible and should be covered with an ice and water shield.

Attached to Roof Ridge

After the shingles have been installed, it’s time to install the metal roofing. Then, you can start securing the Asphalt Roof Valley flashing. Then, you’ll need to use roofing cement or mastic to hold the new metal. You should also make sure that the valley flashing is attached to the roof ridge and is not exposed. This will help prevent leaks from occurring.

Resistant to Corrosion

Then, you’ll need to choose the type of metal roof you’re going to install in the Asphalt Roof Valley. Some roofers will use aluminum or low gauge metal for the valleys. Heavy gauge metal is better for the long-term. A closed valley is not a good choice for a steel roof, as it will be harder to keep the metal in place. In addition, a closed shingle will be less resistant to corrosion.

Overlapping

When installing metal roof to a traditional asphalt roof, there are a few important steps to follow. The first step is to install the ice and water protector. This protects the metal from leaks. Then, you can begin to install the metal roof to the valley. You can then continue the process by overlapping the shingles and the valley flashing. It will be easier for you to see how to install a metal roofing to an Asphalt Roof Valley if you follow these simple steps.

Tin Snips

The next step in installing the metal roof is to build the Asphalt Roof Valley. After you have built the valley, the next step is to install the metal roof on the other side. The valley flashing needs to be overlapping the first panel by about four inches. Then, you must overlap the second panel by five inches. The last step is to screw the metal roof to the valley using a screwdriver or tin snips.

Match Shingles

After you have completed the first step, you can move on to the next step. You should install the next piece of flashing on the Asphalt Roof Valley and then the next one should overlap it by four inches. Afterwards, you need to install the final panel. After installing the metal roof, you can paint the flashing panels to match the shingles. This will add a dramatic look to the exterior of your home.
