6 Best Cable Mounting Clips for Cedar Shakes to Use

Cedar shakes offer unmatched aesthetic appeal and natural insulation, but they present a unique challenge when managing cable runs. Standard fasteners will crack the wood or create entry points for moisture, leading to premature roof failure. Choosing the right mounting clip preserves the integrity of the cedar while keeping your low-voltage or power cables secure. These six options represent the industry standard for protecting both the roof system and the wiring.

PPC SHC Shake Clip: The Pro’s Go-To Choice

The PPC SHC clip is engineered specifically for the irregular thickness of cedar shakes. Unlike flat-surface clips, it features a unique geometry that accommodates the natural taper of the wood without requiring force.

Contractors favor this clip for its consistency during large-scale cable management jobs. It bridges the gap between shakes cleanly, ensuring that the pressure is distributed evenly across the surface rather than concentrated on a single fragile edge.

Reliability in high-wind zones is its primary advantage. By keeping the cable snug against the roof plane, the SHC minimizes vibration that could otherwise loosen connections over time.

The RACC SSCLP: Best for Coaxial Cable Runs

Coaxial cable is notoriously stiff and difficult to route, especially on textured surfaces like cedar. The RACC SSCLP is designed with a wider cradle that prevents the cable from kinking under its own tension.

This clip excels on roofs where the cable needs to follow a precise, long-distance path. Its low profile prevents the “sail effect” where high winds catch the wire and create leverage that could pry a standard clip loose.

Stick to this model when dealing with thicker gauge shielded cables. Its robust construction prevents the cable from sliding or drooping between support points.

TFC Shingle Clip: Top Non-Penetrating Mount

Non-penetrating clips are the gold standard for cedar roofs because they eliminate the risk of water infiltration. The TFC Shingle Clip utilizes a tension-based design that grips the edge of the shake without requiring nails or screws.

Installation is straightforward, sliding firmly under the butt end of the shake. This mechanical lock is secure enough to withstand thermal expansion, which is critical since cedar moves significantly as it gains and loses moisture.

Avoid using this clip on severely aged or brittle cedar. If the shakes are too soft or decayed to handle minor pressure, they will crumble, rendering the friction-fit useless.

Malco S6C Siding Clip: The Most Versatile Option

While technically a siding tool, the Malco S6C has become a staple for roofers managing cables on steeply pitched cedar faces. Its design allows it to hook into tight gaps where standard roofing clips simply won’t fit.

This is the ultimate problem-solver for complex roof geometries, such as valleys or around dormers. When a cable must traverse a transition area, the versatility of this clip allows for a cleaner, more professional route.

Expect a steeper learning curve with this option, as it requires careful manipulation to ensure the grip is seated correctly. It is not a “set-it-and-forget-it” tool, but it is indispensable for custom cable management.

Perfect Vision Universal Clip: Best for DIYers

For those handling a single-run cable installation, the Perfect Vision Universal Clip offers a balance of price and ease of use. It is designed to be user-friendly, requiring no specialized tools to seat properly.

The clip’s design accounts for various cable diameters, making it a reliable choice for mixed media runs. It holds firm on most cedar thicknesses, provided the shakes are installed at a standard exposure.

Be aware that these clips prioritize simplicity over heavy-duty load capacity. They are perfect for residential data or coaxial lines but should not be used to support heavy electrical conduit.

Seacure SSF-WSHK Clip: For Coastal Climates

Coastal environments demand materials that can withstand salt-spray corrosion. The Seacure SSF-WSHK is manufactured from high-grade stainless steel, ensuring it will not rust or bleed streaks onto the cedar surface over time.

Rust-prone fasteners are the primary cause of unsightly cedar discoloration. Using these clips prevents the “weeping” effect that can ruin the appearance of a premium cedar roof, protecting the long-term investment of the wood.

This is a premium-cost solution, but the longevity is unmatched in harsh weather. If the job site is within five miles of the ocean, the extra expense for stainless steel is mandatory rather than optional.

How to Install Clips Without Damaging Shakes

Installing clips on cedar requires a delicate touch, as the wood is prone to splitting if forced. Always ensure the shake is structurally sound before applying pressure; if the wood feels mushy or thin, relocate the clip to a stronger area.

Start by gently lifting the butt of the shake using a shingle ripper or a thin pry bar. Slide the clip into place, ensuring it is flush against the wood surface.

Never force a clip if it meets resistance. If the gap between shakes is too tight, it is safer to move the clip two inches to the left or right than to risk cracking the shake.

Why You Should Never Nail Cables to Cedar Shakes

Nailing cable straps directly into cedar shakes is a fundamental error that leads to roof leaks. Every nail hole becomes a conduit for moisture to enter the felt underlayment and eventually the roof deck.

Even if the nail head is sealed with roofing cement, cedar oil will eventually degrade the adhesive. Furthermore, the expansion and contraction of the cedar will cause the nail to wiggle, enlarging the hole over time.

Use friction-fit or tension-based clips exclusively. If a mounting point absolutely must be secured with a fastener, ensure it is driven into a rafter or solid wood framing, and properly flash the area to prevent rot.

Choosing a Clip: Material and UV Resistance

Material selection determines the lifespan of the mounting system. Plastic clips must be UV-stabilized, as the harsh sun on a rooftop will turn standard plastic brittle and cause it to snap within a few seasons.

Stainless steel remains the gold standard for durability and long-term performance. While coated steel or plastic is cheaper, they are rarely cost-effective over a ten-year cycle given the labor cost of replacing failed clips.

Consider the thermal properties of the material as well. Metal clips are preferred for high-heat areas to prevent degradation, while high-density polyethylene is suitable for standard, temperate residential applications.

Planning Your Cable Route on a Shake Roof

Proper planning minimizes the number of clips required and keeps the roof looking clean. Follow the natural lines of the roof, such as ridges or hips, to hide cables and avoid unnecessary exposure.

Minimize the crossing of valleys, as these are high-flow areas for water. If a cable must cross a valley, use a protective conduit to ensure the cable doesn’t impede drainage or get caught in ice dams.

Map out the route on the ground before climbing the ladder. Identify potential obstacles like chimneys or vents, and ensure the cable run is as short as possible to reduce total weight and surface interference.

Securing cables on a cedar shake roof requires respecting the delicate nature of the material while choosing hardware that can withstand the elements. By selecting the right clip for your specific environment and installation, you ensure the roof stays watertight and the wiring remains secure. Take your time during the routing process, prioritize non-penetrating solutions whenever possible, and your installation will provide years of trouble-free performance.
