This time in the sun will give it a little time to expand. Measure it again and adjust it if needed to fit in the J-channel.

Open eave installation procedures are also used when removing damaged soffit during a re-siding project. Enclosed eaves—eaves with soffit in place are typical of re-siding projects. Installation Over Open Eaves Follow this five-step procedure: Install receiving channels soffit receiver or J-channel.
There are several ways to install receiving channels for soffit. You can use accessories such as J-channel or F-channel. The best approach is to select a method that works most effectively with the construction techniques used to create the eave.
Examine figures 64 through 67 and find one that most closely resembles the construction methods used on this particular project. Install the receiving channels following the details shown in figures 64 through Local environmental conditions particularly high wind zones and building codes may call for different installation techniques. Installation Over Enclosed Eaves The procedure used to install soffit over an enclosed eave in a remodeling project is almost identical to that used for an open eave in new construction.
NOTE: If the existing soffit is rotted or damaged, remove it completely before installing vinyl soffit, then use the instructions for open eaves.
Determine the preferred method of installing soffit at the fascia board. New Construction Projects Begin by installing receiving channels on all four sides of the porch Fig. If F-channels are being used, nail them to the existing walls.
If J-channels are being used, a nailing base will have to be installed. When using light blocks to attach external light fixtures, install them to adequate backing.

Metal soffits have also been common. One of the most popular soffit materials, however, is vinyl. Both metal and vinyl are available in a variety of colors to match metal and vinyl house siding. These materials offer the advantage of no painting or finishing and little maintenance. These soffits come in preformed lengths that are cut to fit into matching, preformed receiving channels to hold the soffits in place in the same manner as metal or vinyl siding installation.
Soffit installation or replacement is easy with these materials, even for a first-timer. Metal or vinyl soffits also come as solid panels or perforated to provide ventilation. Soffit materials may be vinyl, metal or wood. Ventilated soffit materials can help prevent winter ice dams and keep the home cooler in the summer months.
The type of soffit installation depends on the type of material and the eave construction. You should also check local building codes for the amount of ventilation required in your area, as well as the required or suggested application methods.
This may also depend on the windloads in some areas. One factor is the maximum permissible span of the soffit material. Soffits usually range from 16 to 24 inches wide. For instance, CertainTeed Ironmax soffits may span 24 inches without additional nailing strips, if permitted by code rules.
Vinyl is one of the most popular soffit materials. Photo courtesy of CertainTeed. The installation also depends on whether the eave construction is open or closed. Open eave construction, where the rafters or trusses are exposed, is common on new construction. Closed eave, where an existing soffit is in place, is typical of remodeling projects. Rotted or deteriorated wooden soffits should be removed before installation of new vinyl soffits. Installation of vinyl depends on the type of construction, open or closed eave, and whether the fascia cap is to be applied.
You may also wish to install a vinyl fascia cap over the fascia board that encloses the front of the eave. In this case the fascia cap or coil stock must be installed first as it supports the outer edge of the soffit. First step is to apply the receiving channel or channels, depending on the type of installation needed. The first step is to determine the amount of material needed. To determine the number of squares of soffit required, measure the under-eave areas and multiply the length by the width for each overhang.
Add up the total of all overhangs and divide the total by to determine the number of squares. Next measure the total linear feet of installation components, including: F-channel, J-channel, H-bar, undersill trim and fascia. Add 10 percent to your total for waste and miscalculation.
Prep the area by nailing all loose boards and trim securely in place. Remove any downspouts or lighting fixtures that are in the way. Tie back trees and shrubbery so you have easy access to the eaves.
Allow for expansion and contraction when nailing in place. Open eave installation of a vinyl soffit begins by first installing the proper receiving channels. Either F-channel or J-channel can be used.
