Cedar Roof Treatment

Cedar roofing is valued for its natural beauty, character, and durability, but constant exposure to sunlight, rain, moisture, temperature changes, and organic growth can gradually affect the wood. Proper cedar roof treatment can be an important part of maintaining an existing cedar shake or cedar shingle roof.

At Cedar Roof Cleaning, we provide professional cedar roof treatment and maintenance services designed specifically for natural wood roofing. With more than 60 years of family experience, we understand how cedar ages and how important it is to use products and methods appropriate for cedar roofing.

Our goal is simple: protect and maintain your existing cedar roof while preserving its natural appearance and ability to breathe.

Unlike manufactured roofing materials, cedar is natural wood. It is continually exposed to UV rays, rain, humidity, airborne debris, moss, algae, and seasonal weather conditions.

Over time, cedar may become dry, discolored, weathered, or increasingly susceptible to organic growth.

A properly selected cedar roof treatment may help:

• Protect the wood from environmental exposure
• Repel water without completely sealing the cedar
• Reduce conditions favorable to surface growth
• Provide UV protection when an appropriate treatment is used
• Maintain the natural appearance of cedar shakes and shingles
• Support an overall cedar roof maintenance program
• Preserve an existing cedar roof that remains in serviceable condition

The Cedar Shake & Shingle Bureau recognizes topical treatments as one option for installed cedar roofs but recommends using products specifically appropriate for cedar roofing rather than sealants or waterproofing products.

Applying a treatment over a dirty or heavily contaminated cedar roof is not the approach we recommend.

Before treatment, the roof should be evaluated for dirt, moss, algae, lichen, leaves, debris, and deteriorated cedar. When necessary, the roof should first be professionally cleaned so the condition of the cedar can be properly assessed.

Our process may include:

Cedar Roof Inspection

We inspect the cedar shakes or shingles for visible deterioration, damaged areas, organic growth, and other conditions that should be addressed before treatment.

Cedar Roof Cleaning

When needed, accumulated dirt, moss, algae, and organic material are removed using cleaning methods appropriate for cedar roofing.

Minor Cedar Roof Repairs

Loose, cracked, missing, or badly deteriorated shakes may need to be repaired or replaced before treatment.

Cedar Roof Treatment

Once the roof is properly prepared, an appropriate cedar roof treatment can be applied based on the condition of the wood and the needs of the roofing system.

This clean, repair, and treat approach allows us to address the cedar roof as a complete system rather than simply spraying a product over an existing problem.

Cedar Roof Preservative Treatment

Homeowners sometimes refer to cedar treatments as cedar roof preservatives, conditioners, coatings, or sealers. However, these products are not all the same.

The Cedar Shake & Shingle Bureau recommends that topical products used on cedar roofs be specifically suitable for cedar roofing and identifies options such as non-film-forming UV inhibitors and EPA-registered wood preservatives. It also advises against products that act as sealants, waterproofers, or plasticizers.

This distinction matters because cedar needs to breathe. Completely sealing the wood can interfere with its ability to release moisture naturally.

Generally, a cedar roof should not be sealed with a waterproof coating.

It may sound logical to seal wood against moisture, but cedar roofing needs to be able to dry naturally. Trapping moisture within the roofing system can be counterproductive.

Instead, homeowners considering treatment should use products intended for cedar roof maintenance and appropriate for the particular roof and climate.

This is one reason professional evaluation is important before applying anything to an existing cedar roof.

Cleaning and treatment can often make a significant difference in the appearance of weathered cedar, but homeowners should have realistic expectations.

Natural cedar changes color as it ages. New cedar typically has warmer tones, while older cedar gradually develops gray and brown weathering.

The purpose of professional cedar roof treatment is not to make an older roof permanently look brand new. The primary goal is to maintain and protect serviceable cedar while improving its overall appearance when possible.

A roof that looks old does not automatically need to be replaced.

Dark staining, moss, algae, accumulated debris, and weathering can make a cedar roof appear to be in worse condition than it actually is. Cleaning the roof can reveal the true condition of the cedar underneath.

If the majority of the shakes remain serviceable, a combination of cleaning, localized repairs, and appropriate treatment may be an option.

If deterioration is widespread or the roofing system has reached the end of its useful service life, treatment is not a substitute for necessary repairs or replacement.

We inspect the roof first so we can recommend the appropriate course of action.

There is no single treatment schedule appropriate for every cedar roof.

Factors such as roof age, previous maintenance, surrounding trees, shade, moisture exposure, climate, ventilation, and the condition of the cedar can all affect maintenance needs.

Consider having your cedar roof evaluated if you notice:

• Significant weathering or discoloration
• Moss, algae, or lichen growth
• Areas that remain damp or shaded
• Accumulated leaves and organic debris
• Cedar that appears dry or heavily weathered
• Previous treatment that has substantially weathered away
• A roof that has recently been professionally cleaned

A professional cedar roof inspection can help determine whether cleaning, repair, treatment, or a combination of services is appropriate.

Treatment works best as part of a broader cedar roof maintenance program.

Regular inspections can identify damaged shakes, flashing problems, excessive debris, and organic growth before they become more extensive. Cleaning helps remove material that can hold moisture against the roof, while repairs address individual damaged or deteriorated shakes.

The Cedar Shake & Shingle Bureau notes that accumulations of needles, branches, leaves, and dirt should be removed because cedar needs to breathe. It also notes that heavy moss can retain soil and moisture that may harm the wood over time.

By combining inspection, cleaning, repair, and appropriate treatment, homeowners can take a more complete approach to caring for their cedar roof.
