Should Gentek Shakes and Scallops Cover the Whole House or Be Used as Accents?

Gentek Fairhaven Sound shakes and scallops can serve as whole-house cladding or as specialty accents. The right approach depends on the home’s architecture, the number of transitions, installation access, fixed exterior materials, budget, and the visual effect the homeowner wants to achieve.

Both Applications Are Legitimate

PEPA’s architectural guidance identifies shake and shingle polymeric cladding as suitable for whole-house use or accent areas. Gentek presents Fairhaven Sound as a polypropylene specialty-siding collection with Traditional Shake, Scallop, Cape Cod Shingle and Hand-Split Shake profiles.

Those sources establish that both approaches are possible. They do not establish which one is appropriate for a particular property. That choice should come from the architecture and project conditions—not a product photograph viewed in isolation.

Whole-House and Accent Applications Compared

Decision factor	Whole-house application	Accent application
Visual effect	Creates a continuous, highly textured exterior identity	Draws attention to selected architectural features
Material quantity	Requires substantially more specialty siding	Uses fewer panels but may require additional transition accessories
Installation pattern	More continuous field installation, depending on the house	More starts, stops and interfaces within a smaller area
Color strategy	One dominant color must work across every elevation	Allows controlled contrast with the primary siding
Architectural risk	Texture may overwhelm a simple façade	Arbitrary accents may make the exterior look fragmented
Future repair	More of the exterior depends on one specialty product	Smaller quantities are affected, but high gables can be difficult to access

When Whole-House Shakes Can Look Appropriate

Whole-house coverage can produce a calm, unified result when the house is naturally compatible with a shingle or shake expression. Possible candidates include some Cape Cod, Shingle-style, coastal, cottage and intentionally rustic designs.

The building has a relatively simple form that benefits from continuous texture.
The roof, windows and trim provide enough structure to balance the siding pattern.
Masonry and other fixed materials work with the selected factory color.
The homeowner prefers a unified exterior rather than contrasting material zones.
The project budget accommodates specialty material across all included elevations.
The contractor has addressed corners, penetrations and wall-to-roof transitions in the estimate.

Whole-house coverage does not require an aggressive color. A complex texture often looks more composed when the primary color is restrained and the trim creates a clear frame.

When Whole-House Coverage Can Become Too Busy

Texture has visual weight. Repeating deep shake shadows across a large, complicated house can compete with windows, porches, masonry and roof forms.

The façade already contains several projections, rooflines and ornamental elements.
A strong shake pattern is combined with highly contrasting corners and trim.
The garage dominates the front elevation and receives the same visual emphasis as the entrance.
Multiple shake or scallop profiles are combined without architectural justification.
A historically clapboard-dominant house loses its characteristic horizontal proportions.

More texture is not automatically more character. Once every surface becomes an accent, the house no longer has a focal point.

When Accent-Only Siding Is Usually Stronger

Accent applications are often effective when the building already provides a natural boundary. Upper gables are popular, but they are not the only option.

A front-facing gable above the main entrance
Dormers separated from the main wall plane
A projecting bay or tower
A porch gable with sufficient trim depth
An upper story divided by a genuine band or structural transition
A rear addition that needs to relate to the original house without copying it exactly

The accent should end at a real edge, trim band, corner, roofline or change in wall plane. Stopping in the middle of an uninterrupted wall usually looks less intentional and complicates water-management detailing.

Why Accent Siding Is Not Automatically the Cheapest Option Per Square Foot

Accent areas use less specialty material, but material quantity is only one part of installed cost. Small gables and dormers can involve staging, steep roof access, detailed cutting, multiple penetrations and a high proportion of perimeter trim.

A contractor’s price may be influenced by:

Total measured wall area
Waste created by angles and short sections
Height and roof access
Removal and disposal of existing cladding
Substrate repair and preparation
Flashing and water-resistive-barrier work
Transition bands and specialty trim
Windows, vents, lights and utility penetrations
Minimum labor, delivery or setup charges

Accent siding may reduce the total project price while still carrying a higher installed cost per square foot. Estimates should separate material quantities, accessories, preparation and labor rather than relying on one simplified square-foot number.

Whole-House Coverage Also Has Hidden Estimating Variables

Covering more wall area does not mean the estimate is simply the accent price multiplied by the home’s square footage. Whole-house projects involve their own cost drivers:

Inside and outside corners
Window and door surrounds
Soffit and fascia interfaces
Decks, porches and attached structures
Meter bases, service equipment and exterior fixtures
Roof-to-wall and masonry transitions
Different wall heights and staging requirements
Material storage and jobsite handling

Ask for a project-specific takeoff. Gentek publishes profile dimensions and packaging information, but those specifications do not account for the waste and accessories required by a particular building.

Do Not Compare Profiles by Carton Count Alone

Fairhaven Sound profiles have different exposures, panel dimensions and packaging quantities. A carton count without the corresponding stated coverage can create a misleading comparison.

Measure each wall section separately.
Subtract openings only according to the estimator’s consistent method.
Separate rectangular fields from gables and irregular sections.
Use the current coverage data for the exact profile and color.
Add a waste allowance based on layout—not an arbitrary universal percentage.
Count trim and transition components separately.
Confirm carton rounding before the order is finalized.

Color Strategy for Whole-House Shakes

A whole-house shake surface already creates substantial light and shadow. Adding strong contrast at every corner, window and roofline can make the exterior visually restless.

A balanced whole-house palette often uses:

One dominant factory siding color
A coordinated or moderately contrasting trim color
One limited focal color at the entrance
Roofing and masonry as part of the palette rather than background objects

Gentek’s Color Clear Through® system is intended to help coordinate siding, soffit, fascia, trim and rainware colors. Verify the availability of every selected product and finish; similarly named colors across different materials can still reflect light differently.

Color Strategy for Shake and Scallop Accents

Accent color should create a relationship, not a collision. Compare the proposed accent with the primary siding, roofing, masonry, window frames and garage door.

Desired effect	Starting strategy	What to check
Quiet texture	Choose body and accent colors with similar value	Make sure the profile remains visible from the street
Defined gable	Use moderate contrast supported by a clear trim boundary	Confirm the gable deserves to become the focal point
Dark architectural depth	Relate the accent to roofing, masonry or another permanent material	View a physical sample in direct and indirect sunlight
Traditional decorative effect	Select scallops only where the architecture supports ornament	Avoid adding several competing accent profiles

Transitions Are Part of the Wall Assembly

The horizontal line between primary siding and a shake or scallop accent is not merely decorative. The transition must terminate both products correctly while maintaining the intended drainage and flashing relationships.

PEPA states that polypropylene siding should be installed according to the manufacturer’s specifications and applicable codes. Generic vinyl-siding instructions should not be assumed to replace Gentek’s requirements for a Fairhaven Sound profile.

Ask the contractor to identify the proposed transition component on the elevation and in the written scope. “We will trim it out” is not enough detail for a critical horizontal intersection.

Installation Questions for Either Approach

Has the exact Fairhaven Sound profile been identified?
Is the substrate suitable for the manufacturer’s fastening requirements?
How will the water-resistive barrier and flashing be repaired or installed?
Where will each material begin and end?
Which trim components will be used at transitions?
How will expansion and contraction be accommodated?
How will courses align around corners and across adjacent wall sections?
Will high accent areas remain reasonably accessible for inspection or repair?
How much labeled spare material will remain after completion?

A Practical Decision Framework

Photograph every elevation. Do not design only the street-facing wall.
Identify real architectural zones. Mark gables, bays, dormers and changes in wall plane.
Create two simple concepts. Compare a whole-house option with one disciplined accent option.
Use physical samples. View them beside the fixed exterior materials at different times of day.
Request separate estimates. The scopes must identify preparation, accessories and transitions.
Review future repair implications. Consider access, spare material and dependence on a particular profile and color.
Choose the quieter successful design. If both options improve the house, the one with the clearer hierarchy will usually age better visually.

Compare the Options in Davenport

Suburban Wholesale and Supply can help Quad Cities homeowners and contractors compare Fairhaven Sound profiles, factory colors, dimensions, package coverage and compatible components.

Bring full-elevation photographs and measurements to 3602 North Harrison Street in Davenport. For a meaningful comparison, request takeoffs for both the whole-house and accent concepts rather than assuming that a smaller accent area will have the lowest installed square-foot cost.

The Bottom Line

Whole-house Fairhaven Sound can create a unified shingle or shake identity. Accent-only use can provide texture and focus while allowing horizontal siding to remain dominant. Neither approach is automatically more attractive, affordable or easier to install.

Let the home’s architecture determine where the material belongs. Then compare complete project scopes—including preparation, waste, access, trim and transitions. The best choice is the one that looks intentional from every elevation and can be installed correctly within the actual budget.
