How to Start a Siding Contracting Business

Siding contracting is a large average-ticket exterior remodeling business with strong storm-restoration tailwinds in much of the country. A typical residential siding job runs 2,000-3,500 sq ft at $7-$13/sq ft installed for vinyl, $9-$17 for fiber cement, and $11-$22 for engineered wood (LP SmartSide). That puts the average siding ticket at $18,000-$50,000, and full-wrap fiber cement on a 3,000+ sq ft house regularly exceeds $70K-$100K.

That ticket size is both opportunity and trap. The opportunity: a solo owner-operator with a 2-3 person crew can do $400K-$900K in year one or two. The trap: each job is large enough that miscalculating labor or material on the first 5-10 jobs can wipe out the year's profit. What success looks like in year one: 12-22 completed siding jobs, an average ticket of $24K-$38K, gross margin of 25-35% before owner pay, and a healthy mix of insurance/storm and direct retail.

The failure mode is consistent: new siding contractors underestimate scaffolding, ladder time, and trim work on complex roof lines; they don't understand the insurance claims process well enough to handle storm work; and they get squeezed on cash flow buying materials upfront on a $40K job.

Before opening a siding company, plan on 2-4 years working as an installer under a quality contractor. Vinyl siding has a relatively shallow skill curve — most installers are productive within 6-12 months — but the difference between a beginner and a master shows up in the trim work, the J-channel detailing, and the integration with windows, doors, and roof junctions. Fiber cement (James Hardie, Allura, Nichiha) is significantly more demanding: cuts have to be made with a dust-collection saw, fasteners have to be placed correctly to not blow out edges, and the install instructions are long and warranty-binding. Engineered wood (LP SmartSide, Weather Logs) sits between the two. Most siding contractors specialize in one product family in year one and add others as the portfolio justifies it.

Certifications matter for retail credibility. James Hardie offers the Elite Preferred Contractor program, requiring training, completed jobs, and warranty registration; Hardie Elite contractors typically charge 10-20% more than uncertified installers because the manufacturer warranty extends. LP SmartSide has the Pro program. CertainTeed has Master Craftsman. VSI (Vinyl Siding Institute) has a Certified Installer program. Collect the ones that match your product mix.

Licensing varies. California requires a C-61/D-12 specialty license. Florida requires a state Building Contractor or Specialty Structural license depending on scope. Arizona requires a state license. North Carolina, Virginia, and most of the Southeast require state licensing. Texas, Pennsylvania, Ohio, and most of the Northeast have no state license but require local registration and permits. Roofing license is sometimes adjacent — many states regulate roofing and siding under the same exterior contractor category.

Lead-safe (EPA RRP) certification is mandatory for any pre-1978 home — and most siding work involves removing existing siding which exposes painted substrate. RRP certification is $300 plus annual firm fee. Skipping it on a pre-1978 house is a $37,500/day federal fine. Do not skip.

Form a single-member LLC ($40-$500 filing fee depending on state). Get an EIN. Open a business checking account immediately — siding deposits are large, and commingling them with personal funds is the fastest way to lose LLC protection. S-corp tax election typically makes sense once net profit clears $80K, which most siding contractors hit in year two.

Insurance and bonding requirements:

Sales tax: most states tax materials at point of purchase to the contractor, with labor non-taxable, and the customer is invoiced one combined contract amount. A few states (Hawaii, New Mexico, South Dakota, West Virginia) tax the gross contract. Storm-restoration work paid by an insurance company is handled identically to retail — the homeowner is the customer, the insurance company is the funding source.

Siding is priced per square foot of wall area installed, with separate line items for trim, soffit, fascia, scaffolding, and tear-off. The 2026 ranges:

Vinyl (standard double-4 lap): $7-$10/sq ft installed. A 2,500 sq ft house is $17,500-$25,000.

Insulated vinyl (rigid foam backer): $9-$13/sq ft. Same 2,500 sq ft house is $22,500-$32,500.

Fiber cement (James Hardie, Allura): $10-$15/sq ft for standard color, $12-$17/sq ft for ColorPlus prefinished. A 2,500 sq ft house is $30,000-$42,500. With Hardie Trim and architectural details, $45K-$60K.

Engineered wood (LP SmartSide): $11-$18/sq ft installed.

Cedar shake or natural wood: $15-$22/sq ft for lower grades, $20-$30+/sq ft for premium clear cedar.

Tear-off and disposal: $1.50-$3/sq ft additional.

Trim, soffit, fascia: $8-$15/lf for aluminum or vinyl, $14-$28/lf for fiber cement or wrapped wood.

Key pricing discipline: never quote without measuring with a wheel and ladder; physically count corners (every outside corner is 1.5-2 hours of trim work); verify substrate (sheathing replacement adds $4-$7/sq ft of affected area); price scaffolding separately on tall houses (a 3-story house adds $1.50-$3/sq ft).

For labor: a 3-person crew installs 800-1,400 sq ft of vinyl per day, 500-900 sq ft of fiber cement per day. Plug in a fully-loaded crew cost of $130-$200/hour and the per-sq-ft math holds.

Siding has three distinct acquisition channels and the best contractors run all three:

Storm and insurance restoration. Hail, wind, and tree-damage events are a steady source of insurance-paid siding work in much of the country. Storm restoration requires understanding the claims process — meeting the adjuster, supplementing the estimate, working with Xactimate line items, and managing depreciation/recoverable depreciation flow. Storm work pays at insurance scope rates, which are often slightly below retail but extremely high volume after a major event. Building relationships with 2-3 public adjusters and joining a storm-restoration network can supply 30-60% of year-one revenue.

Direct retail (homeowner-direct). Google Local Services Ads, Google Search ads, and Google Business Profile reviews drive direct retail leads. Cost-per-lead runs $80-$200 for siding (higher than most trades because the ticket is high). A photo-rich GMB with 30+ reviews and weekly post updates is the highest-ROI organic channel. Door-knocking after a storm event is still effective in many markets.

Builder and remodeler subcontracting. Custom builders need a siding sub on every new build. Remodelers want a siding partner for whole-house remodels and additions. A relationship with 2-3 builders supplies steady, lower-margin (15-25% gross instead of 30-40%) but predictable volume that fills the calendar.

Real estate agent referrals for tired-siding flips and pre-listing refreshes. A single agent in a hot zip code can be worth 4-8 jobs per year. A printed flyer with three before/after photos is sufficient.

Lead generation services (Modernize, Angi, HomeAdvisor). Mixed reviews. Cost-per-lead is low ($30-$80) but lead quality is variable and these leads are often shopped 3-4 ways. Use cautiously, never as the only channel.

Siding has a specific operations problem most other trades don't share at the same intensity: the materials list is huge, much of it is special-order from local supply houses, and the lead time on color-matched fiber cement or trim accessories can be 2-4 weeks. A typical siding job materials list includes the primary siding (in the ordered color), trim (matching color), soffit panels, fascia material, J-channel, F-channel, undersill, corner posts, starter strips, fasteners (specified by manufacturer), house wrap, flashing tape, drip edge, and accessories. Forgetting any one of those stops the crew. Siding contractors who survive year two have a documented per-product, per-job materials checklist that prints alongside every signed contract.

The operations stack a new siding business needs:

A CRM for the lead and customer record, with substrate notes, color/product selection, and the estimate history.

An estimate and contract tool that handles line-item pricing and exports both a customer quote and an internal materials pull list.

An e-signature tool to capture the contract and all change orders.

A scheduling and dispatch tool to coordinate the crew, the materials delivery date, and the dumpster pickup.

An invoicing and deposit tool that handles progress draws (33% deposit, 33% on tear-off complete, 34% on final) with ACH and card.

A documentation tool for permits, before/after photos, manufacturer warranty registrations, and storm-claim documentation.

Deelo is the operations stack a siding contractor needs in one platform at $19/seat/month. The CRM holds the customer record with substrate condition photos, color selections, and Xactimate line items if the job is insurance-paid. Custom fields capture the manufacturer (James Hardie, LP, CertainTeed), the color SKU, the linear feet of trim, and the warranty registration number — searchable years later when a homeowner has a question.

The Estimates and ESign apps generate a quote with line-item materials and labor, capture the deposit, and produce the signed contract. The Field Service app schedules the crew with the materials delivery date and the dumpster drop. The Invoicing app handles the 33/33/34 progress-draw structure with ACH and card. The Docs app stores permits, warranty registrations, before/after photos, and Xactimate documentation.

The Automation app fires the workflows that protect margin: a deposit request after the quote signs, a materials-order checklist when the deposit is received, an SMS to the customer the morning of crew arrival, photos uploaded to the customer record from the field, a manufacturer warranty registration reminder when the job is complete, and a review request 48 hours after final walkthrough.

For a 4-person siding operation (owner + 3 installers), Deelo is $76/month — compared to $250-$450/month running a stack of QuickBooks + Jobber + DocuSign + Google Workspace + a separate storm-claim tool, all of which Deelo replaces.
