TL;DR:
Cedar shake roofs offer natural elegance and long-term durability — but they require regular care. From routine inspections to moss removal and sealing, smart maintenance can prevent costly damage. Call The Cedar Cleaners at 647-694-0523 for expert cedar roof care across Ontario.
Why Maintaining Your Cedar Shake Roof Matters
Cedar shake roofs are a classic choice for homeowners who want unmatched beauty paired with rugged strength. With rich texture, natural insulation, and eye-catching curb appeal, cedar shakes stand out — but only if they’re well cared for.
Proper maintenance helps these roofs last up to 30 years or more. Since cedar is an organic material, it’s vulnerable to weather, pests, and plant growth. That means your attention (or ours!) is the key to preserving its charm and structure.
Start With Regular Inspections
Routine inspections are your first line of defense against expensive repairs. We recommend inspecting your cedar shake roof at least twice a year — once in spring and again in fall — plus after major storms.
What to look for:
- Cracked, curled, or missing shakes
- Mold, mildew, or rot
- Signs of pest activity
- Blocked or overflowing gutters
- Damaged flashing around vents, chimneys, or skylights
Pro Tip: Never walk on your cedar roof. Use binoculars for visual checks or hire professionals like The Cedar Cleaners for safe, up-close inspections.
How to Inspect Your Cedar Shake Roof Safely
If you’re doing a visual scan yourself:
- Use a sturdy ladder and have someone with you for safety.
- Examine the perimeter first — fascia boards, eaves, and gutter edges.
- Look for moisture discoloration, sagging, or separation between shakes.
- Check attic ceilings for signs of leaks or light penetration.
If you see red flags or you’re unsure what you’re looking at, we’re happy to help with a detailed inspection and estimate.
Keep It Clean: Debris and Moss Removal
Leaves, branches, and organic buildup are your roof’s enemies. They trap moisture and create the perfect environment for mold, moss, and even insects.
Here’s how to keep your cedar roof clean:
Remove Debris the Safe Way
- Use a leaf blower to remove loose materials gently.
- Avoid using sharp metal tools that can scratch or crack cedar.
- Clear out gutters and downspouts to prevent water backup.
Tackle Moss and Algae the Right Way
- Apply a non-toxic cedar-safe roof cleaner. Avoid bleach or harsh chemicals.
- Use a soft-bristle brush to gently scrub moss off the surface.
- Rinse thoroughly using a low-pressure garden hose.
- For large infestations, call in professionals for safe removal and follow-up treatment.
Apply Preservatives and Sealants
Preserving your cedar shakes protects them from sun, water, and decay. It’s one of the most powerful steps you can take to extend your roof’s life.
Wood Preservative Application
- Choose a high-quality product formulated for cedar roofing.
- Apply evenly with a sprayer or brush across the entire roof surface.
- Allow proper drying time and reapply every 3–5 years depending on weather exposure.
Sealants for Extra Protection
While not always required, sealants can help repel moisture in vulnerable areas. Use a breathable cedar-specific sealant and focus on:
- Valleys and roof joints
- Ridge caps and seams
- Transition areas around vents and skylights
Common Issues (and How to Handle Them)
Even with great care, issues may pop up. Don’t panic — many problems are manageable if caught early.
Rot and Decay
If you spot soft, crumbling wood or visible fungal growth:
- Replace affected shakes promptly.
- Inspect the underlayment to ensure the damage hasn’t spread.
- Schedule a professional inspection if unsure of the damage extent.
Insect Damage
Cedar can attract carpenter ants, termites, or other wood-loving pests.
- Keep your roof clear of organic debris.
- Treat infestations early with cedar-safe pest control solutions.
- Consider preventive treatment if your property is heavily wooded.
