What Goes Under Cedar Shingles?
Updated: Jul 28
Diverge from the standard exterior design and material choices of your neighbors with a stunning cedar shingle roof. Cedar shingles are the most stylish and sophisticated roofing material available today, guaranteed to turn the heads of those who drive down your street, even as the material ages and transforms from bright reddish tones to a distinguished silver and gray hue.
Along with unmatched natural aesthetics, cedar shingles offer a range of advantages, including improved energy efficiency, durability and natural resistance.
Despite its superior appearance and performance, you mind wonder what goes under shingles. Cedar shingles still rely on proper roof underlayment and installation techniques to guarantee lasting home protection, appeal and longevity.
Cedar Shake Wood Roof Underlayment: What To Put Under Shingles?
Cedar shakes and shingles are known for their outstanding natural beauty and exceptional long-term functionality. But the lasting effectiveness of your cedar roof will largely be determined by what type of underlayment is installed under the cedar shingles.
Underlayment is a material layer installed over the roof deck, below the shingles and other roofing materials. With proper cedar roof underlayment, you can minimize updrafts that cause fires to penetrate the roofing materials, improve household insulation, and prevent moisture and other harmful elements from entering your home.
Underlayment will also let the cedar roof shingles last longer, better protecting the materials from damaging weather conditions that can prematurely cause the wood to rot, break or crack.
The most common underlayment installations beneath cedar shingles are:
Felt underlayment/tar paper: Felt materials are a traditional underlayment option for cedar shingles made from a base of natural materials like wood cellulose or synthetics like fiberglass and coated with a protective asphalt coating to repel moisture and debris. Felt underlayment is typically available in 15-pound or 30-pound rolls. Felt underlayment offers extra weather barriers to reduce blow-offs and water damage, provides roof deck protection, and prevents roof sheathing unevenness.
Synthetic underlayment: With modern improvements and manufacturing techniques, synthetic underlayments are now considered the best material installed under cedar shingles. Synthetic underlayments are made from polyester, fiberglass and polypropylene. Synthetic underlayments are lighter than felt materials, more resilient and resistant, resist UV damage, are easier to install, offer improved insulation, and extend the lifespan of cedar roofs.
But what is the best underlayment option for cedar roofs? While either felt or synthetic underlayment will provide dependable results and support the performance of your cedar shingles, synthetic options are considered the best installation option today.
