Usually, the roof soffit is located on the roof's underside. It extends horizontally across the entire cross-section of the overhang. When it comes to flat roofs, it helps to have a roof soffit because it enhances proper ventilation of the interior space. Ventilation can be a challenge for flat roofs with tiny spaces between the roof and the adjacent walls.
The roof soffits have small vents that allow the exchange of air between the inside and outside of the building. It's a clever way of keeping the inside of a commercial building habitable, considering that the spaces will often host many people at a time. The following piece will give you some of the tips you need for framing a flat roof's soffit:
Start With the Basics
The first step to nailing your framing project is to make sure that you have everything in place. Usually, this means having the proper safety equipment such as protective gloves and goggles. The next step is to stretch the measuring tape from one end of the wall to the other, ensuring that it can cover the entire length of the area you want to frame. Next, the saw comes in for cutting the wooden frames and boards to the appropriate size.
Create Your Roof Ledger
You cannot frame your flat roof's soffit without creating a roof ledger. The ledger is made by securing the appropriately sized boards to the flat roof's horizontal underside. It is advisable to use steel-coated or galvanized nails for this task, which prevents rust regardless of prolonged exposure to moisture. When done fitting the boards, the resulting fixture forms the ledger. It is part of your soffit's framing.
Make the Framing Attachments
Use your measuring tape to establish the distance between the roof's rafter and the ledger. Thereafter, cut one of the wooden boards according to the length you just measured and place it such that one of its ends sits secured against the rafter. The other end should lie against the ledger, and both ends must be held firmly in place using steel nails. Repeat this process for all the sections that require a soffit framing.
Create the Vents
The final step is to create vents that will allow the exchange of air and ensure proper ventilation. Ideally, the vent holes should be on every alternate corner of the roof rafter. A circular saw will suffice for this final step. If you have trouble cutting out the circular shape, try mapping them on the frame then cut along the circumference.
