Choosing Siding + Soffit Subcontractors

Think About:

• Experience with the specific system (Hardie, metal panels, cedar, stucco, ACM, etc.)

• Do they install:

  • WRB (weather-resistant barrier)?

  • Flashing and trim?

  • Caulking and paint?

• Do they understand rainscreen details and drainage planes?

• Can they interface with windows, doors, roofing, and masonry trades?

• Are they manufacturer-certified for warranty compliance?

• Do they include scaffolding or man lifts in their scope?

Subcontractors to Select:

• Siding installation subcontractor

• Trim carpentry installer (if separate)

• Soffit + fascia installer

• Sheet metal subcontractor (flashings + drip edges)

• Caulking + sealant installer

• Exterior painting crew (if required)

• Scaffold or boom lift subcontractor

Choose subs that deliver a complete weatherproof exterior, not partial pieces.

Choosing Siding & Soffit Materials

Think About:

• Required durability for climate + exposure

• Compatibility with home style + architectural intent

• Material movement → expansion gaps + fastener schedules

• Flame and mold resistance in key zones

• Warranty requirements for accessories

Materials to Select (as applicable):
Primary Siding Systems:

• Fiber cement panels or lap siding (Hardie)

• Cedar siding (lap, shingles, T&G)

• Vinyl siding

• Metal panels (standing seam, plate)

• Wood composites

• Stucco + lath systems (if included in this category)

• Brick or stone veneer (if combined scope)

Soffit & Fascia:

• Vented or solid soffit panels

• Aluminum or PVC fascia

• Wood soffit (cedar, fir)

• Venting accessories for attic airflow

WRB / Waterproofing:

• House wrap or liquid-applied barrier

• Rainscreen battens or furring strips

• Flashing tapes + corner flashings

• Kickout flashings (critical for water protection)

Trim & Accessories:

• Exterior trim boards (wood, composite, metal)

• Belly bands, column wraps

• Window & door flashing kits

Every component must protect water ingress — not just look good.

Choosing Tools, Equipment & Rentals

Think About:

• Height and access challenges on elevations

• Accurate cutting systems for clean reveals

• Airflow — soffit venting must meet code

Tools & Equipment to Select:

• Siding nailers / screw guns

• Cutting systems (fiber cement saw blades, metal shears)

• Laser level, chalk lines, square sets

• Scaffolding or boom lifts

• Safety rails and tie-off anchors

• Caulking tools + sealant guns

• Brake for bending metal trim

• Dust collection for cutting cement board

Right tools ensure precision and airtight workmanship.

Choosing Vendors & Supply Sources

Think About:

• Color batch matching — order full lots at once

• Long lead times for custom trims or panel systems

• Paint/stain compatibility if pre-finished

• Warranty requirement: manufacturer-certified distributor

Vendor Types to Evaluate:

• Lumber & siding distributors

• Specialty metal fabricators

• WRB & rainscreen supply vendors

• Fastener suppliers (corrosion-rated)

• Paint + stain suppliers (if finishing on site)

• Scaffolding rental provider

Solid supply coordination prevents weather exposure risks.

Choosing Inspections & Documentation Partners

Think About:

• Proper fastening patterns must be photographed

• WRB and flashing must be documented before covered

• Soffit venting must match attic design & mechanical plans

Partners to Select:

• Inspector for weather barrier + flashing

• Photographer/document tech

• Thermal/air sealing specialist if required

• Manufacturer rep for high-end systems

Documentation = future leak protection + warranty defense
