Wood Shingle - Cedar Roofing and Siding Basics Guide

A wood shingle is a thin, sawn wood roofing or siding piece installed in overlapping courses to shed water from a roof or wall surface.

What It Is

Wood shingles are more uniform and refined in appearance than wood shakes. They are typically sawn on both sides, which gives them a smoother face and more consistent thickness for a flatter, more regular finished surface.

In residential construction, wood shingles are best known as cedar roof coverings, but they are also used on exterior walls in some architectural styles. Their durability depends on wood species, exposure, ventilation, fasteners, and local climate.

Types

Common types include machine-sawn cedar shingles for roofing, sidewall shingles for exterior cladding, and treated products designed for improved fire resistance. Grades, lengths, and exposures vary by intended use.

Where It Is Used

Wood shingles are used on steep-slope roofs and on some exterior walls, especially in traditional, coastal, cottage, and historic-style architecture. Their use may be limited by local fire codes, insurance requirements, or maintenance concerns.

How to Identify One

Identify a wood shingle by its relatively thin profile, straight butt edge, and more uniform appearance compared with a shake. Splitting, curling, erosion at the butt, discoloration, and biological growth are common signs of aging.

Replacement

Replacement can range from spot replacement of damaged shingles to full reroofing or recladding when wear is widespread. Repair decisions should consider remaining roof life, underlying sheathing condition, and local code requirements for wood products.

Wood Shingle — FAQ

What is the difference between a wood shingle and a wood shake?

A wood shingle is thinner and more uniform because it is sawn for a smoother finish. A wood shake is thicker, rougher, and more irregular in appearance.

Can wood shingles be used on walls as well as roofs?

Yes. Wood shingles are used both as roof coverings and as exterior siding on some homes, though the product details and installation methods differ.

How long do wood shingles last?

Life span depends on the species, installation quality, roof pitch, ventilation, sun exposure, and moisture conditions. High-quality cedar shingles can last for decades, but neglected roofs fail much sooner.

How do I know if wood shingles need replacement?

Watch for repeated leaks, widespread splitting, curling, missing shingles, heavy moss, and surface erosion. When those conditions are widespread, isolated repairs usually buy only limited time.

Do wood shingles require special code approval?

They can. Some jurisdictions limit wood roofing because of fire exposure unless a listed fire-rated assembly or approved treated product is used.
