Why Hire Professionals for Cedar Roof Repairs?
Cedar roofs are one of the most attractive and sustainable roofing options available, but they do require skilled maintenance. Over time, sun, storms, and seasonal shifts wear down cedar shingles. That’s when professional attention becomes critical.
At The Cedar Cleaners, we specialize in preserving and restoring cedar roofs across Ontario. Our licensed technicians know what to look for, what to fix, and how to prevent further damage — all while maintaining the natural charm of your cedar roof.

When Should You Call for Cedar Roof Repair?
Minor imperfections like light curling or surface fading are often harmless. But if you notice the following issues, it’s time to take action:
Sun and Storm Exposure
While cedar weathers beautifully over time, prolonged exposure without protective treatment can lead to uneven aging or decay. If your shingles are drying out, turning grey too quickly, or showing cracks, they may need conditioning or sealing.
We recommend scheduling periodic inspections — especially after harsh winters or heavy storms — to keep your cedar roof in top shape.

Water Damage Warning Signs
Cedar naturally resists water, but neglect allows moisture to seep into shingles and roof decking. Watch out for:
- Wet attic wood
- Ceiling water spots
- Dripping in your home
- Sagging drywall
- Sunlight showing through your roof
If you’re seeing even one of these symptoms, your cedar roof needs immediate inspection. We’ll check for underlying issues like damaged flashing or improperly sealed shingles.
Moss, Mildew, and Fungus
Ontario’s climate encourages moss growth on shaded cedar rooftops. Left untreated, moss traps moisture, weakening shingle integrity and leading to rot or leaks.
At The Cedar Cleaners, we safely remove moss and apply eco-friendly treatments that inhibit regrowth without damaging the wood.
Shingle Distortion: Cracking, Curling, and Cupping
Not all visual changes require action — but here’s what does:
- Cracking: Cosmetic hairline cracks are normal. Deep splits, however, may allow water in and compromise fastening.
- Cupping: Caused by inconsistent drying, where the underside remains moist. The result? Concave shingles that hold water.
- Curling: Often caused by age, poor quality materials, or subpar installation. Light curling can be left alone, but widespread warping needs repair.
Missing Cedar Shingles
Wind, birds, raccoons — all can dislodge shingles. Even a single gap exposes your roof to leaks, mold, and pest infestations. If you notice dark spots, debris in your gutters, or open patches, call us to replace shingles before the problem grows.
