Most gutter flashing installation packages are sturdy enough, however, for people who want their gutter flashing to be even stronger, personal installation and gutter flashing set up is also an ideal option. Some of the steps in gutter flashing installation include:

  • Minimizing joints
  • Assembling strong seams
  • Adding roof flashing for efficient water flow. This process also includes off-the-shelf metal gutter parts.

It’s better that people who work comfortably with basic hand tools handle this work. Though the steps are easy, just like other work, it’s not for everybody to do.

Step 1: Plan the Project

Before installation, planning and evaluation is important. Since personally installing gutter flashing can help save a lot of costs as compared to getting professional help, it should fit just right. Planning and evaluation help avoid any miscalculations and problems.  Check the soffit and the fascia for any rotten parts. This should be replaced before installing any gutter flashing. Since most houses have crown molding or trim board nailed to the fascia, this part should also be removed. When installing gutter flashings, it is important to have a flat plane.

Step 2: Measure the House and Come Up with a Sketch

It is important to note down the length of the roof as well as the downspout locations. This will help make sure that gutter flashing installation is accurate. The downspout locations should be measured adding a few feet of allowance. For every downspout, three elbows are required. Elbows have two different types: one turns to the side of the downspout, one to the front. Most gutter flashing installations only needs front elbows. The use of side elbows are on a case to case basis.

Step 3: Assembling the Gutters

Most people find it hard to assemble gutter up on the roof of when stepping onto a ladder. The trick here is to assemble the joints on the ground. After several parts are assembled together on the ground, it’s easier to connect then up above the ground. When joining the parts of the gutter flashing, it’s also necessary to overlap parts in certain measures. Splicing the sections of the gutter should not be done spontaneously. It takes a lot of planning and evaluation before a section is spliced. Without planning and evaluation, problems can simply occur. The gutter should be lapped in such a way that the inside is directed downhill. This will help avoid water leaks out the seam.

Step 4: Addition of Outlets and Downspouts.

In this step, downspout tubes should be cut within each location of the downspout. In order to do so, calculate the distance of the house’s corner to the center of the selected location of the downspout. Make sure that there are no obstructions along the way. The dimension measured should now be applied to the gutter. The downspout outlet is made from this measurement.

For further information on this matter, it’s best to consult other people who have installed gutter flashing in their homes.
