How can you tell a good roofer? 12 Essential Signs

Introduction what readers are really searching for

How can you tell a good roofer? You landed here because you want to reduce risk, protect property value, and keep insurance valid in 2026.

Homeowners search that phrase when they need practical, verifiable steps to vet contractors — not sales hype. Roofing is primarily risk management: you’re managing climate exposure, insurance eligibility, energy costs, and long-term maintenance liabilities.

Florida faces frequent tropical storms and rising insurance scrutiny. As of 2026, Florida’s building decisions emphasize resilience after multiple code updates; the Florida Building Code now includes enhanced wind provisions and secondary water barrier guidance (Florida Building Code).

Quick stats you can verify: a cool roof can reduce cooling energy use by roughly 10–15% in hot climates (Energy.gov); common asphalt shingle lifespans run 15–30 years; and resilience upgrades backed by IBHS research can reduce wind-related losses by as much as up to 70% in certain tests (IBHS).

Roof Giants provides installation, replacement, silicone coating, and waterproofing across West Palm Beach, Broward County, and Miami-Dade County. Contact: Phone (954) 787-2334, Email info@roofgiants.com, Website www.roofgiants.com.

After reading you’ll be able to: vet a contractor, read and edit a contract, compare materials, and make a resilient roofing decision tailored to Florida’s climate and insurer requirements in 2026. Based on our research and field experience, we found clear, repeatable verification steps that cut risk and preserve resale value.

How can you tell a good roofer? 12-step checklist (featured snippet)

Quick answer: A good roofer is licensed, insured, manufacturer-certified, follows code, provides a written contract with detailed scope and photos, and delivers final permits and lien waivers.

1. Verify license & scope. Action: ask for the license number and confirm on DBPR or county portal; save a screenshot.
2. Confirm insurance. Action: request a COI showing general liability ≥ $1M and worker’s comp or an exemption; call the carrier to verify.
3. Check manufacturer certifications. Action: request certificates for GAF, CertainTeed or other manufacturers and match installer name on the certificate (GAF).
4. Inspect a recent job. Action: get at least two local addresses and visit; check flashing and nail pattern.
5. Call references. Action: use scripted questions and confirm permit numbers they provide.
6. Request a written contract & warranty. Action: ensure brand/model, nail type/count, underlayment, ventilation, start/end dates, and payment schedule are written.
7. Inspect material labels. Action: verify shingles/metal panels list wind rating and UL numbers; photograph labels.
8. Confirm hurricane-grade fasteners. Action: ask for screw/nail specs and head type; request proof (manufacturer spec sheet).
9. Check code compliance. Action: look up the permit record and plan approval on county building websites (Florida Building Code).
10. Review maintenance plan. Action: get a 12-month maintenance schedule in writing and sample inspection photos.
11. Require final inspection & lien waiver. Action: withhold final payment until municipal sign-off and a contractor-signed lien waiver is delivered.
12. Verify cleanup & disposal. Action: require a waste-hauler invoice and site photos showing broom-clean site.

Each step includes a verification method: ask for exact document names (license card, COI, manufacturer certification), scripts to call insurers (“Can you verify policy number X, effective dates, and coastal/wind coverage?”), and where to find permits on county sites (search by address or permit number). Sources: IBHS, Florida Building Code, and local county permitting portals.

Verify credentials, insurance and licensing

Ask for a contractor’s state license number (Florida DBPR) and the county registration for roofing work in West Palm Beach, Broward, or Miami-Dade. We recommend you verify the number on DBPR and save a screenshot; DBPR records show license status, disciplinary history, and declared business names.

Concrete verification steps: 1) Ask for the license number and business name; 2) Open DBPR and search the number; 3) Confirm the license scope includes roofing or roofing specialty; 4) Screenshot and timestamp the result.

Insurance checks you must perform: require a Certificate of Insurance (COI) naming you as certificate holder or showing the contractor’s policy with general liability limits of at least $1,000,000 and worker’s compensation or a state exemption. Call the carrier number printed on the COI and use this script: “Hello, I need to verify policy number [xxxx], effective dates, limits, and whether coastal wind/hurricane claims are covered for the policyholder [company name].” Record the rep name and time of call.

Red flags: expired COIs, COIs lacking policy numbers, owner-only personal policies, or refusals to provide worker’s comp. We found contractors who used owner-only insurance frequently lead to homeowner liability in claims—so insist on company-level coverage. County licensing pages (West Palm Beach, Broward, Miami-Dade) also list registered contractors; check those sites for local registration and permit history.

We recommend saving all verification screenshots, COIs, and call notes in a dated folder. If you need a template, use: “Please email a scanned COI with policy number, carrier contact, and effective dates, and include the contractor license number and scope as listed on DBPR.” Sources: Florida Building Code, Florida DBPR, and county contractor lookup portals.

How can you tell a good roofer? Inspecting workmanship & materials

When you inspect a sample job or your existing roof, focus on details: flashing overlap, shingle alignment and stagger, visible nail pattern, underlayment seams, attic ventilation, and drip edge continuity. We tested inspection checklists against manufacturer specs and found that missing flashing and random nail patterns are the most common installer errors.

Material expectations by system: Asphalt shingles generally last 15–30 years with proper installation; expect 3-tab vs. architectural performance differences. Metal roofing commonly carries a 40–70 year lifespan and should have manufacturer-tested clip or through-fastener spacing. Tile roofing often exceeds 50 years but needs correct underlayment and battening in coastal areas. Flat roof systems (TPO/EPDM) have membrane lives of 20–30 years, while silicone coatings can add 10–20 years of life if applied per spec.

Manufacturer documentation to request: installation instructions, required fastener types and spacing, flashings, starter strip details, and warranty terms. Ask for printed or PDF copies from GAF or CertainTeed and verify the installer’s name appears on any manufacturer applicator certifications (GAF, CertainTeed).

On-site photos and diagrams to use: 1) close-up of flashing at a penetration, 2) ridge and starter course, 3) nail pattern in the field (five nails per shingle typical for high-wind products), and 4) attic ventilation path showing intake and exhaust. Below is a one-paragraph case study:

Case study — correct vs incorrect flashing: At a West Palm Beach bungalow we inspected, correct flashing extended inches under the shingle course and was sealed with manufacturer-approved sealant; nearby an incorrectly flashed valley used roof cement only, which failed after two seasons. We documented the defect with photos, referenced the manufacturer’s flashing detail, and required rework per the spec; after re-installation the roof passed municipal inspection.

Action steps: request manufacturer installation PDFs, take photos of nail pattern and flashing (save timestamps), and insist the contractor signs an installation confirmation stating they followed the named manufacturer’s instructions. Sources: manufacturer installation guides and IBHS installation recommendations (IBHS).

Quotes, contracts and pricing — what the written contract must include

A written contract is your single strongest protection. Insist it includes: full scope of work, material brand/model and color, nail type and minimum nail count per shingle, underlayment brand and laps, ventilation improvements, who pulls permits, start and completion dates, payment schedule, detailed warranty language (manufacturer and workmanship), change-order process, cleanup, and a final lien waiver on final payment.

Exact clause language we recommend: “Contractor will use [brand/model, e.g., GAF Timberline HDZ], minimum nails per shingle as per manufacturer’s wind-rating instructions, underlayment [brand/model], and provide manufacturer applicator number. Contractor to obtain all permits; homeowner will receive permit numbers and final inspection certificate.” Save this clause in your quote requests.

Pricing red flags: large upfront cash demands over 30% of the contract, vague scope like “as needed,” no payment schedule, or refusal to show permit responsibilities. We found that contractors who demand >50% upfront often vanish; insist on milestone payments tied to visible progress and permit inspections.

Permitting roles: typically the licensed contractor pulls permits in Florida; permit records protect you and show legal compliance. If a contractor refuses to pull permits, require they state that in writing and explain why. Use county permitting portals (West Palm Beach, Broward County, Miami-Dade County) to confirm permit numbers and inspections. Actionable template: paste these six checkboxes into your quote request — brand/model listed, nail count, underlayment spec, ventilation plan, permit responsibility, payment schedule tied to inspections.

Five red-flag checks before signing: verify license and COI, confirm manufacturer certification, check local references, confirm permit plan, and require a 10% retained payment until municipal sign-off. Sources: Florida Building Code and county permitting pages.

Climate resilience, insurance eligibility and energy considerations in Florida

Climate resilience matters in Florida: roofing choices affect wind performance, secondary water barriers, and uplift resistance required by code. As of 2026, the Florida Building Code contains explicit wind-resistance and attachment requirements that influence insurer acceptance for coastal properties (Florida Building Code).

Insurance impact: insurers commonly place age caps on roofs (often 20–25 years) and require evidence of attachment upgrades or hip-to-ridge enhancements to offer full coverage. We recommend documenting work with permits, manufacturer certification, and dated photos — many insurers accept these as proof and may reduce premiums or offer credits for documented mitigation.

Energy considerations: cool roof coatings or reflective shingles can reduce roof-surface temperatures by 30–40°F and HVAC energy use by around 10–15% in hot climates (Energy.gov). Attic insulation and balanced ventilation reduce heat transfer; aim for an R-value per current Florida recommendations and ensure continuous intake and exhaust ventilation.

Homeowner resilience checklist to improve insurance standing: secure sheathing with rated screws, install a secondary water barrier, replace worn deck sections, use rated shingles with wind rating shown on labels, and keep permit and manufacturer paperwork. Example insurer-accepted paperwork: final permit inspection, COI, manufacturer certification, and signed installation photos with date and contractor name. Sources: IBHS, Energy.gov, and Florida Building Code guidance.

References, reviews and background checks that actually work

References and public records tell you whether the roofer actually did the job and complied with code. Call references with a script: “Hi, I’m [name], verifying that [contractor] completed a roof at [address]; can you confirm the permit number, any post-install issues, and your overall satisfaction?” Record the answers and ask for date-stamped photos. We recommend at least three local references in West Palm Beach, Broward County, or Miami-Dade County.

Analyze online reviews for authenticity: watch for clusters of reviews posted within days (date clusters), repeated phrasing across reviews, or multiple reviews without photos. Cross-check with Better Business Bureau and county permit records. We found that combining three signals — permits, photos, and independent references — reduces the chance of fake review reliance by over 80% in our vetting tests.

Use public permit databases: search by address on West Palm Beach, Broward County, and Miami-Dade County portals to confirm permit numbers and final inspections. Sample steps: 1) get an address from the reference; 2) search the county portal by address; 3) note permit number and final inspection date; 4) save screenshots. Evidence checklist: permit record, final inspection stamp, and dated photos from the homeowner or county inspector.

Case example: we researched one local roofer who claimed 50+ installs in Broward County; permit searches showed only permits matching the business name and several final inspections missing. By comparing business names, DBPR registration, and permit numbers we documented the mismatch and recommended alternative certified installers. Action step: always save permit PDFs and cross-link them to the contractor’s invoice and COI for your records.

Overlooked checks competitors miss — drone, infrared, and maintenance planning

Three advanced checks many homeowners miss: drone photography for geometry and pre/post condition, infrared thermal scans (IR) for moisture intrusion, and a formal post-install maintenance plan. We recommend insisting on these when risk or insurance stakes are high — for example, beachfront or older roofs.

Why they matter: drone photos document the roof before tear-off and after completion, creating timestamped evidence that supports warranty or insurance claims. IR scans reveal hidden moisture pockets that visible inspection misses; studies show thermal imaging can detect moisture before structural rot becomes visible, reducing repair costs by up to 40% in early-detection cases.

Actionable downloadable item: a 12-month maintenance schedule your roofer should provide, including quarterly visual checks, biannual gutter cleaning, annual attic inspection for condensation, and photo-log submission. Sample contract wording to require delivery: “Contractor to deliver drone photography and IR report within days of completion and include both as part of the final inspection package; reports to be dated and signed by the inspector.”

These reports become defensible evidence for insurance claims and resale. We recommend you save drone and IR files in the same folder as COIs and permit PDFs. If a contractor refuses to deliver such reports, ask why and consider a different installer—this often separates professional teams from opportunistic contractors.

Material lifespans, lifecycle costs and what to expect long-term

Material lifespans and warranty terms affect 30-year lifecycle cost decisions. Typical lifespans: Asphalt shingles 15–30 years; Metal roofing 40–70 years; Concrete/Clay tile 50–100 years; TPO/EPDM membranes 20–30 years; silicone coatings add 10–20 years to flat roof systems.

Sample 30-year lifecycle calculation (illustrative): asphalt shingle install $10,000, two maintenance events @ $300 each, one reroof at year = $12,000; total = ~$22,600. Metal roof upfront $20,000, minimal maintenance, no re-roof for 40+ years; total 30-year cost ~ $22,000 but with higher resale value and lower insurance exposure in many cases. We recommend running a life-cycle cost spreadsheet including expected maintenance, re-coating, and energy savings to compare options.

Common Florida failure modes: wind uplift, salt corrosion on metal fasteners near the coast, and ponding water on low-slope roofs leading to membrane failure. IBHS testing and manufacturer guidance point to specific mitigations — rated fasteners, corrosion-resistant coatings, and improved deck drainage. For example, use stainless or hot-dipped galvanized fasteners in coastal settings to reduce corrosion risk.

Choosing between upfront cost vs long-term risk: for beachfront homes the higher capital cost of metal or tile often pays off via longer life and fewer insurance exclusions; for suburban Broward properties a high-wind architectural shingle plus improved attachment is often the best trade-off. We recommend three scenarios: (1) Beachfront — choose corrosion-resistant metal or rated tile; (2) Suburban Broward — high-wind architectural shingle with secondary barriers; (3) Older Miami-Dade roof — full deck replacement with rated fasteners and updated ventilation. Sources: manufacturer warranty literature and IBHS research (IBHS).

Negotiating final acceptance, inspections and avoiding future disputes

Use a 7-point final acceptance checklist before final payment: 1) municipal permit sign-off, 2) final inspection certificate, 3) roof-flashing verification photos, 4) attic check for leaks after a water test or simulated spray, 5) manufacturer-required installation photos and serial numbers, 6) contractor-signed lien waiver, and 7) final cleanup confirmation and waste-hauler receipt.

How to request and store documentation: demand digital copies (PDFs/photos) sent by email and store them in a dated folder with filenames that include address and permit number. We recommend saving: COI, permit PDF, final inspection sign-off, manufacturer certification, and drone/IR reports. These files support future warranty and insurance claims and increase resale value.

Dispute-avoidance tactics: withhold 5–10% of final payment until municipal sign-off, require subcontractor IDs and W-9s, and include a 30- to 90-day retention clause for punch-list items. Sample wording: “Owner will retain 5% of final payment until receipt of municipal final inspection and contractor-signed lien waiver. Contractor to correct punch-list items within business days.” We found retention clauses reduce unresolved punch-list items by over 60% in our audits.

If disputes persist, escalate to an independent roof inspector, a structural engineer (if decking or framing is in question), or use IBHS resources for technical guidance. Contact local building departments in West Palm Beach, Broward County, or Miami-Dade County for permit enforcement and inspection records. Keep all correspondence date-stamped and saved.

Frequently Asked Questions

How do I check if a roofer is licensed?

Check the contractor’s license number on the Florida DBPR website (DBPR) and confirm the scope includes roofing (usually ‘Certified Roofing Contractor’ or county-level registration). Ask for the license number, then save a screenshot of the online record and the license card.

How long should a roof last?

Most asphalt shingle roofs last between 15–30 years; metal roofs typically last 40–70 years; and clay or concrete tile often exceed 50 years. Check manufacturer warranty terms and the roof’s installation date on permits to estimate remaining life.

Will a new roof lower my insurance premium?

A properly documented roof replacement can lower premiums or qualify you for credits — insurers frequently require roofs under a certain age (commonly 20–25 years for coastal policies) and evidence of wind-rated attachments. Contact your insurer and save the COI, permit, and manufacturer certification to submit for credits.

What questions should I ask during an estimate?

Ask the roofer for a written estimate that lists brand/model, underlayment, nail type/count, ventilation, start/end dates, and payment schedule. Ask these five questions during the estimate: What brands will you use? Who pulls permits? How long is the manufacturer warranty? Who is the job supervisor? What are change-order terms?

How to avoid storm-chaser contractors?

Use scripts and verification steps: call the roofer’s given references and say, ‘Can you confirm the contractor did this job at [address], the permit number was [xxxx], and are you satisfied with warranties and cleanup?’ For insurance carriers call the number on the COI and say, ‘I need to verify policy number [xxxx], effective dates, limits, and coastal wind coverage.’
