Checklists for Roofing Contractors: From Inspections to Job Completion

If you’ve been in roofing for a while, you already know — the job’s never “just another roof.” Every project comes with its own unique set of challenges, including weather conditions, crew issues, and client expectations. One rule that never changes: if you skip the small details, it’ll cost you big later. That’s where a good roofing checklist comes in.

A roofing checklist makes sure nothing gets missed when your crew’s running multiple jobs, and helps you deliver consistent quality. Every solid roofing operation runs on the same principles: safety, quality, documentation, and customer trust.

This guide walks through five key phases of roofing operation: inspection, new roof installation, waterproofing, replacement, and job completion/quality control. Each phase includes checklist items that you can start using today, built around the challenges contractors face in the field.

Phase 1: Roof Inspection Checklist

A detailed roof inspection checklist helps you catch problems before they get expensive. And let’s be real, roofing is one of the most dangerous construction trades, with around 40 fatalities per 100,000 full-time workers. So, safety checks aren’t optional; they’re part of doing business right. 

Inspection checklist

• Property address, client name, inspector, date/time, weather conditions logged.
• Assign inspection number or project code for easy tracking.
• Confirm ladders are tied off; staging planks level and secure.
• Record safety check completion before first roof access.
• Ensure fall-protection anchor points rated for required load.
• Inspect gutters and downspouts for debris, attachment, slope, and damage to fascia.
• Document siding, soffit, and trim condition before work begins.
• Note wall cracks or settlement that could affect flashing alignment.
• Inspect eaves, fascias, and drip edges for deterioration or separation.
• Identify missing, cracked, or curled shingles; check for granule loss or membrane punctures.
• Record slope, drainage paths, and transitions; photograph defects with directional markers.
• Verify continuity around chimneys, skylights, and vents.
• Note any mismatched metals, corrosion, or unsealed joints.
• Inspect vent boots, HVAC collars, skylights, and stacks.
• Confirm airflow is unobstructed; document attic ventilation ratio if accessible.
• Check for daylight intrusion, moisture stains, mold, or insulation gaps.
• Record humidity and temperature readings if possible.
• Capture clear before/after images.
• Attach grid-labeled photos to inspection notes.
• File moisture meter readings, slope measurements, and inspection comments.

Using a digital roofing checklist is the right way to stay organized and keep your inspections consistent. For example, when everything from photos, timestamps, and notes is logged in one place, it’s easier to track past jobs, handle warranties, and follow up for future maintenance. 

Tailor your checklist to match your region and roof types; what matters in a snowy climate isn’t always the same as what coastal crews deal with. And always close with a client sign-off. It keeps everyone aligned and saves headaches later. If you’re already managing jobs with a tool like Zuper’s roofing software, you can easily build and reuse these checklists across projects instead of starting from scratch.

Phase 2: Roofing Checklist for New Roof Installation

Before boots hit the shingles you want to verify specs (material type, underlayment, flashing package), confirm permits are in place, and set up site safety measures (fall protection, staging, secure materials). Also make sure the weather window is acceptable and delivery materials are correct and undamaged.

Pre-installation setup

• Verify contract specs: roofing type, underlayment, flashing system, vent type.
• Confirm permit approvals and material deliveries match order sheets.
• Check weather forecast and staging area access.
• Review crew assignments and safety compliance sign-offs.

Installation checklist

• Deck/structure inspection: confirm substrate is sound, no rot or damage needing repair.
• Ice/water barrier installed where required (cold climates).
• Underlayment installed according to manufacturer specs.
• Install drip edge,vents, ridge vents, soffits/fascias.
• Install primary roofing material: check alignment, nail pattern/fastener count, exposure.
• Install flashing at edges, valleys, walls, chimneys, skylights.
• Seal all penetrations and ensure flashing continuity.
• Clean up debris, collect nails, clear site around roof and ground.
• Final walkthrough: check alignment, fasteners, seals, gutters/downspouts clear.

Post-installation job completion

• Hand over manufacturer warranties, material specs, and maintenance guidelines to the client.
• Photograph the finished roof from multiple angles and both ground and drone (if available).
• Get client sign-off before final invoice.
• Remove scaffolding/staging, confirm no nails or leftover material present, ensure the site is safe.
• Record job details in your system for future maintenance scheduling.

Phase 3: Checklist for Roof Waterproofing

Water infiltration is still one of the top causes of roof system failure. When you do waterproofing correctly you protect the structure below, extend the life of the roof, and reduce emergency call-backs.

Waterproofing job checklist

• Surface preparation: clean roof thoroughly, remove debris, confirm substrate is dry.
• Inspect for existing cracks, joints, drainage issues or ponding. Fix as needed.
• Apply primer or base coat if required by the system.
• Apply waterproof membrane or coating per spec: ensure seams, overlaps, reinforcements are done correctly.
• Flashings: around penetrations, parapets, transitions — must be integrated into waterproof layer.
• Drainage check: ensure water can flow off roof, no ponding remains.
• Curing time: allow product to cure per manufacturer before foot traffic or coverings.
• Final inspection: check for bubbles, blisters, loose adhesion, coverage uniformity.
• Client hand-over: give maintenance instructions, warranty documentation, schedule for re-inspection.

Phase 4: Checklist for Roof Replacement

Sometimes a roof’s just at the end of its life. Curled shingles, missing granules, soft decking, or repeated leaks are all clear signs that it’s time for a full replacement. Sometimes replacement isn’t just about damage — it’s about upgrading. If you’re adding solar panels, adjusting roof pitch, or increasing HVAC load, replacing the roof ensures the structure can safely support those changes and perform efficiently for years to come.

Pre-job

• Conduct structural assessment and verify load-bearing capacity.
• Review local code for tear-off vs. overlay allowances.
• Inspect for sagging, rot, or truss damage; record findings before removal.
• Plan waste disposal, material staging, and access for lifts or dumpsters.
  

During replacement

• Remove old materials systematically; separate recyclables and hazardous materials.
• Repair or replace any compromised decking or framing.
• Choose an appropriate system for climate and building type — ensure slope and insulation requirements are met.
• Install new underlayment, flashing, and ventilation components per design.
• Integrate solar mounts, skylights, or HVAC curbs seamlessly with the new system.
• Inspect nail pattern and fastener depth for each course.
  

Post-replacement checks

• Review roof plane alignment and ridge straightness.
• Verify water-shedding paths; test downspout flow.
• Photograph all completed sections and provide copies for client records.
• Secure warranty documents and sign-offs.
• Dispose of debris responsibly and confirm the site passes safety inspection.

Phase 5: Job Completion & Quality Control Checklist

You’ve done the work. But until you run a final QC you risk missed fasteners, poor flashing, debris left behind, and those lead to callbacks, liability and unhappy clients. A robust close-out checklist protects your profit and reputation.

Final checklist items

• Site clean-up: remove all debris, nails, leftover materials; leave the site safe and tidy.
• Confirm all fasteners secure; flashing properly installed; no loose edges.
• Gutters/downspouts functioning; water flows away from the structure.
• Roof surface uniform and aligned; no visible defects or workmanship mistakes.
• Safety gear removed; fall-protection or staging dismantled properly.
• Conduct a formal client walkthrough covering warranty, maintenance, and inspection intervals.
• Documentation: photos (before/during/after), checklist signed by you and client, project file updated.
• Log client feedback and schedule the first maintenance inspection reminder.
• Close project in your system, invoice accordingly, archive records for service follow-up

Contractors should use the same digital QC forms across every crew to keep work consistent and easy to track. Each phase of the job should include photo proof before any payment is released, so there’s no question about quality or completion. Review and update your checklists every few months to reflect code changes, new materials, or better techniques. Completed checklists also make great training tools for new foremen, helping them learn how you expect jobs to run. Keeping a tight close-out process like this protects your profit, cuts down on risk, and builds lasting trust with clients.
