Cedar roofs are admired for their natural beauty and durability. However, maintaining their pristine condition requires deliberate care. In Charleston, WV, Rainstoppers Roofing provides expert advice and services to help homeowners make informed decisions about sealing and preserving their cedar roofs.
What Makes Cedar Roofs Unique?
Cedar roofing is naturally resistant to weather, pests, and decay. Over time, it develops a charming silver-gray patina, enhancing its rustic appeal. However, without proper care, cedar roofs can become brittle, warped, or affected by moss and mildew.
The Case for Sealing a Cedar Roof
Moisture Protection
Sealing prevents water absorption, reducing risks like swelling, warping, and mold growth. This is especially beneficial in regions with heavy rainfall or high humidity.
UV Resistance
A quality sealant shields cedar from UV rays, slowing the graying process and protecting wood fibers from breakdown.
Longevity
Sealing minimizes wear and tear, extending the roof’s lifespan and reducing repair costs.
Key Insight: Sealing can extend a cedar roof’s lifespan by 5–10 years, making it a worthwhile investment for many homeowners.
Considerations Before Sealing
Climate
In harsh climates, sealing offers critical protection against moisture and UV damage. However, in milder regions, the costs may outweigh the benefits.
Roof Condition
Sealing is most effective on well-maintained roofs. Damaged or aged roofs may require repairs or replacement before sealing.
Maintenance Requirements
Sealing is not a one-time solution. Regular reapplication is necessary, increasing long-term costs and labor.
Arguments Against Sealing
Natural Aging
Some homeowners prefer the unsealed cedar’s natural aging process and silver-gray patina.
Moisture Trapping Risks
Improperly applied sealants can trap moisture, leading to mold and rot—counterproductive to the intended protection.
Aesthetic Considerations
Sealing alters cedar’s natural appearance, which may not align with some homeowners’ design preferences.
Alternatives to Sealing
Regular Cleaning
Consistent maintenance, including debris removal and moss prevention, can significantly improve a cedar roof’s longevity.
Cedar Preservatives
Preservatives protect against UV and moisture without forming a surface barrier, allowing the wood to breathe naturally.
