Miami-Dade Roofing, Impact Windows & Exterior Renovation Firms: A Legal Playbook for Contracts, Permits, Warranties, and Collections

 

If you run a roofing, impact window/door, or exterior renovation company in South Florida, you live in a world of fast estimates, weather windows, permit queues, manufacturer specs, and demanding homeowners/GCs. One vague scope line, one unwritten change, or one release signed too early can wipe out a project’s margin.
I’m Attorney Yoel Molina. Our firm has worked with construction and home-improvement companies like yours across Miami-Dade—teams that sell and install roofs, impact windows/doors, gutters, solar, and interior buildouts. This guide distills the legal moves that protect your profit, speed approvals, and keep receivables clean while you scale. (Many local firms in this space publicly emphasize roofing and impact windows in Miami—your contracts should mirror those realities.) ( BBB)
 

Who This Guide Is For

 

  • Roofing contractors (re-roofs, repairs, coatings, tile/shingle/metal/flat)
  • Impact window and door dealers/installers
  • Exterior trades: gutters, soffit/fascia, waterproofing, stucco, siding, solar tie-ins
  • Full-service remodelers offering interiors (kitchens, baths, flooring) in addition to exteriors
 

Executive Checklist (Start Here)

 

  • Separate, attorney-drafted templates for roofing vs. impact windows/doors vs. interior remodeling—don’t rely on a “one-size” home-improvement form.
  • Lock down scope by line item (materials, counts, profiles, colors, flashing, underlayments, tie-ins), plus a clear exclusions list.
  • Make permitting/AHJ reviews, engineering, and manufacturer specs part of the written scope—build time and cost contingencies for comments and re-inspections.
  • Change-order discipline: no extras without a signed CO; price by unit rates or lump sums with a standard markup and payment trigger.
  • Progress payments tied to milestones; retainage caps; deposit timing for long-lead windows/doors and custom glass.
  • Warranty language that’s real: separate workmanship vs. manufacturer warranties; set conditions (maintenance, ventilation, waterproofing, hurricane prep).
  • Collections playbook: interest, late fees, stop-work rights, conditional lien releases, and personal guaranties when appropriate.
  • Subcontractor control: written sub agreements, COIs naming you as additional insured (primary & non-contributory), safety and cleanup requirements, and photo documentation standards.
  • Insurance & risk transfer: balanced indemnity, waiver of subrogation, and proof of manufacturer-trained install for warranty eligibility.
  • Dispute triage: escalation → executive call → mediation in Miami-Dade; venue and Florida law locked into every agreement.
 

Close the Sale—Without Opening Legal Holes

 

Proposals That Convert (and Protect)

  • Precise materials list: system type, brand, profiles, colors, gauges, fasteners, underlayment, flashing metals, adhesives, sealants, opening sizes, glass specs, energy ratings, hardware, and finishes.
  • Weather and access: define staging, driveway protection, lift/crane use, weekend/after-hours limits, and who moves furniture/appliances.
  • Hidden conditions: wood rot, fascia/soffit, termite damage, existing moisture intrusion, code upgrades—priced by unit (e.g., per sheet of decking, per LF of fascia) so you’re not “eating” surprises.
  • Allowances: use for unknowns (e.g., sheathing replacement) and reconcile with change orders.
  • Photos & sign-offs: include pre-job photos and require a pre-install walk-through approving color/finish and opening sizes.
 

Permitting & Inspections (AHJ Reality)

Miami-Dade permitting, NOA/FL approvals, and inspections can stretch timelines. Bake in:
  • Permit responsibility: who pulls, who pays, how long it reasonably takes, what triggers schedule relief.
  • AHJ comments = CO: if plan review adds straps, nailing patterns, shims, buck framing, or flashing revisions, it’s a compensable change.
  • Failed inspections: outline chargeable re-inspections when caused by site issues outside your control (access blocked, utilities off, other trades).
(Local firms openly market roofing and impact windows; your form should reference permits/inspections consistent with those scopes.) ( BBB)
 

Payment Structures That Keep Cash Flowing

 

  • Deposits for custom orders: collect material deposits before ordering impact units or specialty metals; make deposits non-refundable after manufacturer release.
  • Milestone billing: e.g., 10% contract/engineering, 40% upon material delivery, 30% mid-install, 20% substantial completion (or when windows/doors pass final).
  • Retainage caps: set a small holdback (e.g., 5%) tied strictly to punch-list items—not to unrelated parts of the project.
  • Card/ACH authorization: get it signed at contract; include late fees, interest, and recovery of attorney’s fees.
  • Stop-work rights: after written notice for nonpayment, you may suspend without being liable for delay penalties.
 

Change Orders Without the Drama

 

  • Triggers: concealed damage, AHJ comments, owner design changes, manufacturer backorders requiring equivalent substitutions.
  • Pricing: pre-set unit rates (per sheet, per LF, per opening) or T&M with photos; always include overhead & profit.
  • Authorization: e-signature in the field from the named decision-maker; no text-only approvals unless your contract allows it and you capture them to the file.
  • Schedule: COs extend time; put the number of additional days on the CO itself.
 

Warranties That Won’t Burn You

 

  • Workmanship vs. manufacturer: your labor warranty is separate from the manufacturer’s coverage; never promise more than the manufacturer provides.
  • Conditions: gutters cleared, sealant maintenance, hurricane prep (e.g., shutters closed), AC/ventilation requirements, moisture management—make these a condition of any leak or fogging claim.
  • Exclusions: windborne debris impact, ponding due to structure, existing leaks elsewhere, and water intrusion tied to other trades (stucco/painting/irrigation).
  • Claims process: photos, access, and inspection window; your choice of repair method.
  • Transferability: if offered, limit to one transfer within X days of sale with admin fee.
 

Documentation That Wins Inspections, Referrals, and Disputes

 

  • Before/after photos of every slope/opening with close-ups of flashing, fasteners, buck frames, sealant joints, and labeling (for impact glass).
  • Daily logs capturing crew counts, weather, deliveries, inspection outcomes, and neighbor issues.
  • Manufacturer packets saved to the job folder: NOAs/FL approvals, installation manuals, pressure/water ratings.
  • Customer acknowledgments on substantial completion and punch acceptance—don’t rely on a “we’ll email later.”
 

Subcontractors: Trust, But Paper It

 

  • Written sub contracts with scope exhibits, cleanup requirements, PPE, fall protection, hot-work rules, and photo standards.
  • Insurance: additional insured on a primary and non-contributory basis; waiver of subrogation; matching limits to your prime contract.
  • Quality & safety: rework at sub’s cost; step-in rights if they miss schedule; drug/alcohol policy on occupied homes.
  • Non-solicit: protect your customer list for a defined period.
 

Collections: Be Firm, Professional, and Fast

 

  • Invoice package: contract + COs + delivery tickets + photos + passed inspection results (or homeowner signatures) = approvals move faster.
  • Reminder cadence: friendly reminder at 5 days past due, formal notice at 15, demand at 30, then file or refer per your policy.
  • Releases: conditional lien waivers for payments in process; unconditional only after cleared funds.
  • Personal guaranties: use for thinly capitalized LLCs or large custom orders.
 

E-Commerce & Inside Sales (If You Quote Online/By Phone)

 

  • Click-wrap T&Cs with conspicuous acceptance at checkout or e-signature on mobile quotes.
  • Lead times: realistic windows for custom impact units; communicate substitutions proactively if manufacturers shift models.
  • Curbside deliveries: define risk-of-loss transfer; require photo proof at drop.
 

Five Costly Pitfalls (and How to Avoid Them)

 

  • Vague scopes: “Re-roof per code” invites disputes. List system, layers, penetrations, drip edges, flashing metals, and decking allowances line-by-line.
  • Free extras: train teams that no text = no change; use a one-page CO with e-signature.
  • Early releases: never hand over a final unconditional release until the wire clears. Use conditional forms.
  • Loose warranty promises: don’t promise “no leaks ever.” Tie coverage to maintenance, weather events, and adjacent-trade conditions.
  • Sub exposure: if a sub fails fall protection or leaves debris, you own the claim—paper your safety/cleanup standards and audit them.
 

Local Context: Why Miami-Dade Details Matter

 

South Florida exterior work is code-dense and time-sensitive: roof uplift ratings, NOA/FL approvals, large missile impact glazing, and hurricane-season scheduling. Many Miami contractors publicly highlight roofing, impact windows/doors, financing options, and rapid response; your agreements and SOPs should match that market positioning—clear scope, strict change-order rules, and airtight collections.
