Best Fiber-Cement Siding Shingles for Vintage-Style Home Exteriors
GAF WeatherSide offers several fiber-cement siding shingle styles for homeowners repairing or updating a vintage-looking exterior. The Purity Straight is best for a classic straight-edge appearance, while Purity Wavy adds a curved lower edge. Profile 12, Profile 9, and Profile 14 offer different dimensions and vertical striated textures, so matching existing siding is the main selection factor. These products are described as asbestos-free and pre-primed; compare dimensions and surface styles before choosing.
| Product | Best For | Listed Size |
|---|---|---|
| WeatherSide Purity Straight | Straight-edge repairs | 12 x 24 inches |
| WeatherSide Profile 12 | Vertical striated texture | 12 x 24 inches |
| WeatherSide Purity Wavy | Wavy-edge appearance | 12 x 24 inches |
| WeatherSide Profile 9 | Narrower, longer panels | 9 x 32 inches |
| WeatherSide Profile 14 | Wider, longer panels | 14-5/8 x 32 inches |
GAF WeatherSide Purity Straight
This 12-by-24-inch option is best for replacing or coordinating with siding that has a straight lower edge and a traditional textured look. GAF describes the shingles as designed to resemble classic asbestos siding while being asbestos-free. The product is pre-primed and has a textured surface.
The listed features also state that the fiber-cement construction is designed to resist warping, rotting, UV degradation, and termite damage. GAF identifies the product as non-combustible per ASTM E136 and UL Classified to ANS/UL723. Choose it when its dimensions and straight-edge profile match the existing installation.
Limitation: The pre-primed finish is not described as a finished color, so confirm any coating or painting requirements before installation.
GAF WeatherSide Profile 12
Profile 12 is best for buyers seeking a 12-by-24-inch shingle with a vertical striated surface. Its listed dimensions match the Purity Straight and Purity Wavy products, but the surface treatment gives it a distinct appearance. This makes it a useful comparison choice when existing siding has vertical lines rather than a more general textured face.
The product is described as asbestos-free, pre-primed, and made from fiber cement intended to resist weather-related damage, warping, rotting, UV degradation, and termites. Its stated fire-related classifications are UL Classified to ANS/UL723 and non-combustible per ASTM E136.
Limitation: A similar size does not guarantee a visual match. Compare the vertical striation and edge shape with the installed siding before ordering.
GAF WeatherSide Purity Wavy
Purity Wavy is best for repairs where the visible lower edge needs a wavy profile rather than a straight one. It measures 12 by 24 inches, and its textured surface is intended to recall traditional siding. The product description identifies it as asbestos-free and pre-primed.
Like the other WeatherSide shingles described here, its fiber-cement construction is listed as designed to resist warping, rotting, UV degradation, and termite damage. The listed classifications include non-combustibility per ASTM E136 and UL Classification to ANS/UL723. Choose it when the edge profile is the key visual match.
Limitation: The wavy lower edge will not match a straight-edge installation, even though the panel dimensions are the same as other 12-by-24-inch options.
GAF WeatherSide Profile 9
Profile 9 is best for projects that call for a narrower, longer panel: the listed size is 9 by 32 inches. Its vertical striated surface provides a different look from the textured Purity styles. The shingles are described as asbestos-free and pre-primed, with fiber-cement construction intended to resist warping, rot, UV degradation, and termite damage.
This product may be a better fit when matching existing siding dimensions matters more than using the common 12-by-24-inch format. GAF also lists non-combustibility per ASTM E136 and UL Classification to ANS/UL723.
Limitation: Its 9-by-32-inch size differs from the other featured options, so do not assume it can substitute for a different panel size without checking layout and exposure.
GAF WeatherSide Profile 14
Profile 14 is best for buyers who need a wider, longer panel with a vertical striated surface. Its listed dimensions are 14-5/8 by 32 inches, making it distinct from the 12-by-24-inch and 9-by-32-inch choices. The product is described as asbestos-free, pre-primed, and intended to provide a vintage appearance.
Its fiber-cement construction is listed as designed to resist warping, rotting, UV degradation, and termite damage. The description also states non-combustibility per ASTM E136 and UL Classification to ANS/UL723. Choose this profile when its larger dimensions and striated face match the home’s siding.
Limitation: Its wider format may not align with existing shingles of a smaller size; measure the installed exposure and panel dimensions first.
Buying Guide: How To Choose Fiber-Cement Siding Shingles
Which dimensions should you match?
Measure the existing shingle’s width, length, and installed exposure. The featured options range from 9 by 32 inches to 14-5/8 by 32 inches, while several Purity and Profile 12 products are 12 by 24 inches. Do not compare nominal panel size alone: the replacement must also suit the course layout and reveal.
Should you choose a straight, wavy, or striated surface?
Match the visible edge and surface texture for the most consistent repair. Purity Straight has a straight lower edge, Purity Wavy has a wavy edge, and the Profile products feature vertical striations. Check the product image and description against the siding in place before selecting a style.
What does pre-primed mean for a project?
Pre-primed describes the supplied surface, not necessarily a final color or a complete finishing plan. Review the manufacturer’s installation and finishing instructions for preparation, compatible coatings, fastening, cutting, and weatherproofing. Fiber-cement installation can require appropriate tools and safety measures; follow product instructions and local requirements.
How should asbestos concerns affect a replacement?
These listed WeatherSide products are described as asbestos-free. However, older siding already on a home may have different materials. Avoid disturbing suspected asbestos-containing siding until it has been assessed and handled according to applicable local guidance.
