Cedar shake siding offers a distinctive, textured look and natural insulation benefits, but weathering, rot, and insect damage can necessitate replacement. This guide covers when to replace cedar shake siding, how to plan the project, materials and methods, cost considerations, and maintenance tips. It targets homeowners across the United States seeking reliable, actionable information on cedar siding replacement and related decisions.
Assessing The Condition And Planning The Replacement
Begin with a thorough evaluation of the cedar shake siding. Look for widespread rot, soft or crumbling boards, and extensive cupping or warping. Signs of hidden damage include interior staining, mold growth, and moisture intrusion around windows and doors. A professional inspection can confirm structural issues such as undersized wall cavities, failed flashing, or termite activity. Before proceeding, determine whether you will reuse the existing sheathing or install new weather barriers, which can impact both cost and performance.
Choosing Between Replacement Approaches
Replacement options vary by material and installation method. Cedar shake can be removed and replaced with the same cedar product, or with alternatives such as fiber-cement siding or engineered wood that mimics cedar texture. Consistently, homeowners weigh aesthetics, maintenance, and long-term durability. Cedar-compatible methods include full replacement of shakes with new cedar, while alternative siding choices may reduce maintenance frequency and improve moisture resistance. Consider matching or upgrading to a hidden-fastener system to minimize surface nails and to improve wind resistance.
Materials And System Design
When selecting cedar shake replacement, choices include Western red cedar, white cedar, or rot-resistant composite options. Cedar offers natural grain, warmth, and a proven track record when properly maintained. For alternatives, fiber-cement products deliver durability and low maintenance with authentic cedar textures. In any system, plan for proper drainage, ventilation, and air barrier installation behind the siding. A continuous weather-resistant barrier, rain screen, and proper flashing at windows, doors, and penetrations are essential for long-term performance.
Removal, Disposal, And Preparation
Old cedar shakes should be removed carefully to minimize damage to the underlying sheathing. Start at the bottom and work upward, taking care around nails and fasteners. If damage is found, repair or replace damaged sheathing before installing new siding. Dispose of deteriorated cedar in accordance with local regulations, and consider recycling options when available. Inspect the wall cavity for signs of moisture damage, and address any leaks or ventilation issues before new siding goes up. Proper cleanup reduces the risk of mold and ensures a clean installation surface.
Installation Methods For Replacement Siding
Installation technique depends on chosen material. For new cedar shakes, use a lattice or diagonal nailing pattern with corrosion-resistant fasteners and corrosion-resistant hardware to prevent staining. A water-resistive barrier or house wrap should be installed over the sheathing to shed moisture, followed by a ventilation gap—often a rain screen—to promote air flow behind the siding. If selecting fiber-cement or engineered wood, follow manufacturer guidelines for nailing patterns, expansion gaps, and trim details. Ensure accurate alignment, even seams, and consistent gaps to maintain a uniform appearance.
Cost Considerations: Materials, Labor, And Project Scope
The total cost to replace cedar shake siding varies by material, house size, climate, and local labor rates. Typical components include materials, removal, disposal, surface prep, painting or staining, and trim work. The following ranges provide a reference, but actual bids will reflect site conditions and selected materials.
| Component | Typical Cost Range |
|---|---|
| New cedar shakes (installed) | $8.50–$12.50 per sq ft |
| Fiber-cement siding (installed) | $5.50–$10.00 per sq ft |
| Engineered wood siding (installed) | |
| $6.50–$9.50 per sq ft | |
| Removal and disposal | $1.50–$4.50 per sq ft |
| Trim, flashing, and accessories | $2,000–$6,000 (typical residence) |
Note: Local labor rates, height of the home, roof overhangs, and access to the exterior surface influence the final bid. Maintenance and finishing (stain or paint) should be budgeted separately if continuing with cedar.
Finishing, Sealing, And Ongoing Maintenance
Finishing cedar shakes with a high-quality exterior stain or paint helps protect against moisture, UV damage, and insects. For cedar replacements, consider semi-transparent stains that allow wood grain to show through while providing protection. Maintenance intervals vary by climate; in humid or rainy regions, re-staining every 3–5 years is common, whereas dry climates may extend this interval. Inspect for peeling finishes, gaps, and water intrusion after severe weather. Clean gutters and ensure proper drainage to prevent staining and rot at the siding base.
Moisture Control And Building Envelope Best Practices
A reliable moisture-control strategy is central to a long-lasting cedar shake replacement. Install a continuous weather barrier, ensure proper flashing at all penetrations, and use a ventilated rain screen if possible. Ensure insulation and vapor retarders are compatible with the chosen siding system. Proper attic and crawl space ventilation reduce condensation and extend the life of the siding. A well-sealed building envelope minimizes energy loss and interior moisture problems that can compromise the new siding.
When To Hire A Professional
Replacing cedar shake siding is a job best suited for experienced DIYers or, more commonly, professional contractors. Seek contractors with proven experience in cedar, fiber-cement, or engineered wood installations, along with valid licenses, insurance, and customer references. Request written bids that include removal, disposal, surface prep, weather barrier, flashing, trim, and a clear warranty. Verify that contractors follow local building codes and obtain necessary permits. A professional job reduces the risk of improper installation, moisture problems, and warranty conflicts.
Permits, Codes, And Insurance Considerations
Local permitting requirements vary by jurisdiction and project scope. Some areas require permits for exterior siding replacement, especially if structural work or electrical/roof elements are affected. Confirm correct zoning compliance, flashing details, and fire-rated materials where required. Verify that the contractor carries liability insurance and workers’ compensation coverage. Retain all permits, receipts, and warranties for future reference or resale considerations. Proper documentation supports value and ensures compliance with local codes.
Environmental And Aesthetic Impacts
Choosing cedar versus alternatives can influence the environmental footprint of a project. Cedar is a renewable resource, but its harvesting and finishing products have environmental implications. Fiber-cement and engineered wood often provide lower maintenance and longer lifespans, which can reduce long-term environmental impact. Aesthetic considerations include color matching with the home’s trim and roof lines, texture depth, and shadow lines created by the shake profile. Homeowners may favor a seamless transition with neighboring exteriors for curb appeal and resale value.
Tips For A Smooth Cedar Shake Siding Replacement
- Get multiple written bids from reputable contractors with cedar experience.
- Ask for a materials list, warranty terms, and planned installation sequence.
- Inspect existing wall sheathing and moisture barriers before replacement.
- Plan for paint or stain color continuity with existing trim and accents.
- Schedule work during favorable weather to reduce moisture exposure during installation.
