Fascia board installation
Fascia boards are an essential component of a deck's aesthetics and structure. They are usually crafted from wood or composite materials and run along the deck's border, elegantly concealing the joists underneath for a seamless and sophisticated finish. Before installing fascia boards, it is important to ensure that your deck joists are properly blocked, spaced, and secured, and that your deck's substructure is healthy.
Step 1: Measure the Roof
Use a tape measure to find the length of your roof. Climb a ladder near the corner of your roof and secure one end of the tape measure to the rafter with duct tape. Reposition the ladder to the other end of your roof, pull the tape measure along the length, and take your measurement. Write down this measurement. Continue taking measurements for any other sections of your roof where fascia boards need to be installed.
Step 2: Select and Cut the Boards
Choose straight boards that are 2 inches (5.1 cm) taller than the rafter ends and treated for outdoor use. The ends of your rafters are typically 6 or 8 inches (15 or 20 cm) tall, so boards that are 8 or 10 inches (20 or 25 cm) tall are ideal. Cut the boards to the required length using a circular saw. If you don't have the necessary tools, ask the hardware store employees if they can cut the boards for you.
Step 3: Adjust the Boards to Match the Roof Slope (Optional)
Although optional, adjusting the tops of the fascia boards to match the slope of your roof will give your home a clean appearance. Set the angle of a circular saw blade to match the slope of your roof and run the saw along the top edge of each fascia board.
Step 4: Miter the Ends of the Boards (Optional)
For a cleaner look at the corners, set the angle of a miter saw to 45 degrees and cut the ends of the fascia boards that will be placed on corners.
Step 5: Position and Secure the Fascia Boards
With the help of an assistant, position the fascia board so it is level with the top edges of the rafters. Use carpentry nails or 2-inch (5.1 cm) wood screws to secure the board. Start by tacking the ends of the board into the rafters, then add 1-2 more nails or screws at each rafter along the length of the board to prevent bowing.
Step 6: Seal Gaps and Nail Holes (Optional)
Apply a thin layer of body filler putty or caulk to the seams and nail holes to lock out moisture. Scrape off any excess putty to ensure a smooth finish.
Step 7: Install Metal Drip Edges (Optional)
Cover the top of the fascia board with metal drip edges to prevent moisture from getting between the boards and the rafters. Secure the drip edges with 2-3 nails along the top, driving them into the rafters underneath.
Selecting the Right Fascia Screws
When attaching fascia boards, it is important to use the right type of screws to address common challenges associated with fascia installation, such as material reaction differences and inadequate fastening. High-quality fascia screws are designed to accommodate the different expansion and contraction rates of composite or PVC materials and wood framing, enhancing stability and security. They also provide precision and ease of installation, often featuring specialized designs that aid in achieving precise alignment and spacing. Additionally, look for screws that are treated or coated to resist corrosion and weathering.
For composite decking, use TOPLoc fascia fasteners and a T20 driver bit. Apply a good-quality exterior-grade construction adhesive to the back of the board, position it flush with the top of the deck boards, and install three fasteners from top to bottom, with the top and bottom screws positioned no more than 1/2" from the end. Repeat this configuration every 12".
For PVC decking, follow the same installation process but use TOPLoc for Advanced PVC hidden fascia fasteners and a TOPLoc fascia drill bit.

Fascia screw head design
When it comes to fascia screw head design, there are a few key considerations to keep in mind. Firstly, fascia screws need to address the common challenges associated with fascia installation, such as material compatibility and expansion and contraction of the fascia boards.
The screw head design plays a crucial role in achieving a seamless and aesthetically pleasing finish. Fascia screws are available in different head styles, each serving a functional or decorative purpose. The two basic designs are countersunk and non-countersunk heads. Non-countersunk heads, where the head is fully exposed, include various styles such as binding, button, cheese, and flange heads. Countersunk designs, on the other hand, consist of flat, oval, and bugle heads. Flat and oval heads typically require a countersunk hole unless the material is very soft. Bugle heads are commonly found in drywall screws, and their design automatically creates a countersunk hole during installation.
To achieve a flawless finish, some fascia screw systems offer colour-matched heads or plugs to conceal the screw heads. This ensures that the screws blend seamlessly with the fascia material, enhancing the overall appearance of the deck.
In addition to the head style, the drive style or drive recess is another important consideration. The drive style refers to the type of tool required to install or remove the screw. Common drive styles include slotted, Phillips, hex, Torx®, and square. Choosing the correct drive style is essential to prevent head damage and ensure a smooth installation process.
Furthermore, if security is a concern, selecting an uncommon drive style can provide an additional layer of protection. Square socket and Torx® drive styles offer a degree of security as they are not as commonly found. For even greater security, consider using pin hex, pin Torx®, or spanner drive styles, which require special tools for installation and removal.

Fascia screw corrosion resistance
Fascia screws are essential for securely fastening fascia boards and ensuring the long-term stability of your deck. When choosing the right fascia screws, it is crucial to consider corrosion resistance, especially if your deck is exposed to environmental factors such as moisture and weather changes.
Corrosion resistance is the ability of a material, in this case, the fascia screw, to resist degradation and maintain its integrity in corrosive environments. Corrosion can occur when metals interact with water, leading to a process known as galvanic corrosion. This is why it is essential to select screws with suitable corrosion resistance properties for your deck fascia.
The Type 316 stainless-steel fascia screw provides superior corrosion resistance. The high-quality stainless steel combines iron with chromium and nickel, increasing its corrosion-resistant properties. This type of screw is designed to withstand extreme environments and offers maximum protection against corrosion. It is an excellent choice for outdoor projects where the screws will be exposed to moisture and weather changes.
Additionally, the Simpson Strong-Tie Fascia-Fastening Solution is worth considering. This system consists of a counterbore bit and a fascia screw, designed to securely fasten composite and PVC fascia boards. The Type 316 stainless-steel screw in this system provides the same level of severe corrosion resistance. The solution allows for the expansion and contraction of the fascia boards, preventing failures due to environmental conditions.
To further enhance the corrosion resistance of your fascia screws, you can follow these best practices:
- Use screws with similar electrochemical properties to the materials they will be fastened to.
- Employ insulating materials to separate dissimilar metals and prevent their direct interaction.
- Ensure that the screw or anchor is the cathode when dissimilar connector metals are present, meaning it carries a negative charge.
- Prevent the exposure and pooling of electrolytes on the screws.
