Begin with the House, Not the Product Sample

Gentek Fairhaven Sound Single Select offers cedar-inspired shakes, scallops and shingle profiles in numerous colors. That range creates useful design possibilities, but availability alone does not make every combination architecturally appropriate.

Start by studying the house from across the street. Identify which elements establish its character: roof shape, gables, porch, window proportions, bay windows, masonry foundation, horizontal siding lines and original ornamental details. The new cladding should support that hierarchy rather than compete with it.

Historic-Looking and Historically Appropriate Are Not the Same

Scallops can feel Victorian, while shakes can suggest Craftsman, Shingle, Cape Cod or rustic architecture. Yet adding a historically inspired profile does not automatically create an authentic restoration. The profile must also make sense for the home’s period, form, original materials and documented construction history.

The National Park Service advises that deteriorated historic material should generally be repaired when feasible. Substitute material is normally considered only after the condition, location and significance of the original material have been evaluated. Its appearance and physical compatibility must also be considered.

Is the Property Subject to Historic Review?

The City of Davenport states that proposed exterior changes to locally designated historic properties are reviewed through its historic-preservation process. Its siding permit information also warns that additional requirements may apply to properties on the Davenport Registry of Landmark Property or the National Register of Historic Places.

1. Check the property’s designation status before purchasing material.
2. Contact the applicable planning, building or historic-preservation office.
3. Ask whether exterior siding replacement requires a permit, design review or certificate of appropriateness.
4. Submit photographs, elevations, material information, colors and proposed trim details when requested.
5. Obtain written approval before ordering nonreturnable or special-order products.

Requirements vary by municipality and property. Davenport guidance should not be assumed to describe the process in Bettendorf, Rock Island, Moline or another Quad Cities community.

Preserve Original Material When Repair Is Feasible

Before covering or removing old wood siding, determine what is actually present. A wall may contain original clapboards, shingles, trim profiles, corner boards or decorative bands beneath a later siding installation. Those materials can provide valuable evidence of the building’s intended proportions.

The National Park Service’s preservation guidance is clear that replacement work reduces historic integrity to some degree. For a historically significant building, replacement should not be the automatic response to peeling paint or isolated deterioration.

• Document existing elevations before anything is removed.
• Determine whether deterioration is localized or widespread.
• Investigate leaks, failed flashing and moisture sources.
• Evaluate whether historic wood can be repaired rather than replaced.
• Retain representative material and measurements when removal is approved.
• Avoid concealing unresolved water or structural problems behind new cladding.

A Profile-by-Profile Design Test

These are design considerations, not claims that a profile is historically correct for every home within a named style.

Restraint Usually Produces the Better Exterior

A common design mistake is combining shakes, scallops, horizontal siding, contrasting corners, decorative bands, shutters and several strong colors on one elevation. Each element may be attractive independently, but together they can flatten the hierarchy of the house.

Use specialty siding to clarify a real architectural transition. A gable, tower, dormer or projecting bay can provide a logical stopping point. Avoid creating arbitrary rectangles of accent siding on otherwise uninterrupted walls.

• Give the primary siding profile the largest visual role.
• Limit specialty siding to one or two architecturally defined areas.
• Use trim bands at genuine material transitions.
• Let original windows, porches and roof forms remain the main features.
• Step back from the color board and judge the entire elevation.

Protect the Home’s Shadow Lines

Historic façades often derive much of their character from depth: window casings project from the wall, corner boards define edges, frieze boards meet the soffit, and water-table details establish the base. A replacement siding project can weaken that character if added wall thickness makes the trim appear shallow.

Measure the proposed wall assembly before installation. Windows, doors, porch connections, utility penetrations and roof-to-wall intersections need compatible flashing and enough visible trim depth. Merely placing narrow surface accessories around these openings may not reproduce the original visual weight or manage water correctly.

Choose Color from Evidence, Not Assumption

“Historic color” is not one universal palette. Victorian-era buildings, Craftsman homes, Colonial Revival houses and early twentieth-century vernacular homes used color differently. Existing photographs, protected paint layers and architectural surveys may provide better direction than a generalized period-color chart.

When strict historical documentation is not required, a disciplined three-part palette often provides a useful starting framework:

• Body color: the dominant horizontal siding or wall material.
• Secondary color: shakes or scallops in an architecturally defined area.
• Trim color: a unifying color around windows, corners, frieze boards and other selected details.

This is a design framework, not a historical rule. Some buildings call for fewer colors, while a carefully researched Queen Anne exterior may support more.

Control Contrast

Strong contrast makes every transition more visible. That can be useful when highlighting a true gable or tower, but it can also expose awkward termination points, undersized trim and irregular window placement.

If the architecture is already ornate, consider closely related body and accent colors. If the house has a quiet form with one important gable, a more noticeable shake or scallop color may be appropriate. Physical samples should be viewed beside the roof, masonry and trim in morning, midday and late-afternoon light.

What Gentek and PEPA Can—and Cannot—Establish

Gentek’s product information establishes that Fairhaven Sound is polypropylene specialty siding offered in multiple profiles and colors. Gentek describes an extended panel length, varied molds and cedar-inspired texture intended to produce a natural-looking appearance.

The Polymeric Exterior Products Association, formerly the Vinyl Siding Institute, provides design resources showing how polymeric siding, trim and accessories can be applied to recognized architectural styles. PEPA’s Designing Style guide includes examples for Queen Anne, Folk Victorian, Craftsman, Cape Cod and other traditions.

These sources demonstrate product capability and design possibilities. They do not prove that a proposed application is historically accurate, locally approved or physically compatible with a particular old wall assembly. That judgment requires property-specific investigation.

Installation Questions That Affect Historic Character

• Will original siding and trim be repaired, retained, covered or removed?
• Has the wall been inspected for moisture, decay and insect damage?
• How will the required water-resistive barrier and flashing be integrated?
• Will added thickness alter the relationship between the siding and window trim?
• How will inside corners, outside corners, frieze boards and material transitions be finished?
• Can decorative elements be removed and reinstalled without damage?
• Are the installer’s methods consistent with Gentek’s instructions for the exact polypropylene profile?
• Have local permit and preservation approvals been documented?

The Bottom Line

Gentek shakes and scallops can support a traditional design, especially when used in gables and other clearly defined architectural areas. They should not be used to manufacture a false history or bury repairable character-defining material without investigation.

The strongest approach is disciplined: verify the property’s status, document the existing exterior, repair historic material where feasible, obtain required approvals, and select a profile whose scale and texture support the house. On an older home, restraint is not a missed opportunity. It is often what makes the finished exterior feel credible.
