Direct Answer
A conditional lien waiver and an unconditional lien waiver differ in when the waiver becomes effective. A conditional waiver generally becomes effective only after the specified payment condition is satisfied, such as a check clearing. An unconditional waiver generally takes effect when signed, even if the expected payment has not cleared.
For Florida roofing projects, this distinction matters because a subcontractor or material supplier may give up valuable lien rights when signing a release. Florida Statutes Section 713.20(7) specifically permits a lienor who executes a waiver or release in exchange for a check to condition it on payment of that check.
Who This Applies To
- Commercial roofing contractors receiving progress payments or final payment.
- Roofing subcontractors working under a general contractor.
- Material suppliers furnishing roofing membranes, insulation, fasteners, or metal panels.
- Property owners and general contractors collecting lien waivers before releasing project funds.
1. Conditional vs. Unconditional Lien Waivers
| Feature | Conditional waiver | Unconditional waiver |
|---|---|---|
| When it takes effect | When the stated payment condition is satisfied. | Generally upon signing, according to its terms. |
| Check has not cleared | The waiver remains conditional if payment has not been completed as required. | The signer may already have waived the covered lien rights. |
| Protection for the roofing contractor | Helps preserve covered lien rights until the payment condition is met. | Offers less protection if the expected payment fails to arrive. |
| Typical use | When signing a release in exchange for a payment that has not yet cleared. | When the signer is prepared to release the covered rights immediately. |
2. Example: A Roofing Subcontractor Receives a Check
Suppose a commercial roofing subcontractor is owed $25,000 for completed work. The general contractor provides a check and asks for a lien waiver.
- Conditional waiver: The subcontractor conditions the release on payment of the $25,000 check. If the check is dishonored, the condition has not been satisfied.
- Unconditional waiver: The subcontractor signs a release that is effective immediately under its terms. If the check later bounces, the subcontractor may have surrendered the covered lien rights and could need to pursue other remedies.
The exact effect depends on the document’s language and applicable law. A conditional waiver should clearly identify the payment and condition rather than relying on an informal understanding.
3. Florida’s Construction Lien Law
Florida Statutes Section 713.20 governs waivers and releases of construction liens. It provides statutory forms for progress payments and final payments.
- Section 713.20(2): A lien right cannot be waived in advance; a waiver is limited to labor, services, or materials already furnished.
- Section 713.20(4): Provides a form for a waiver and release of lien upon progress payment.
- Section 713.20(5): Provides a form for a waiver and release of lien upon final payment.
- Section 713.20(7): Allows a lienor exchanging a waiver or release for a check to condition the release on payment of the check.
Florida’s statutory framework distinguishes progress-payment releases from final-payment releases. Conditional versus unconditional describes the payment condition, not whether the release covers interim work or the final payment.
4. Which Waiver Should a Roofing Contractor Sign?
Before signing, the roofing contractor or supplier should:
- Confirm the payment amount and the work period covered by the release.
- Check whether retainage, disputed invoices, change orders, or later work are excluded.
- Ensure the document clearly states whether effectiveness depends on payment clearing.
- Avoid signing an unconditional release before confirming payment when the funds have not yet cleared.
- Retain a signed copy and payment records for the project file.
Property owners should also collect appropriate releases from relevant subcontractors and suppliers. A waiver from the general contractor does not automatically establish that every party furnishing labor or materials has been paid.
5. Conditional Waivers Are Not the Same as Recorded Lien Satisfactions
A lien waiver or release can waive specified lien rights in connection with payment. If a claim of lien has already been recorded in the county’s official records, a separate satisfaction or discharge may be necessary to remove that recorded lien. Florida Statutes Section 713.21 addresses methods for discharging a perfected lien.
Bottom Line
A conditional lien waiver protects a roofing contractor or supplier by making the release dependent on the specified payment condition. An unconditional waiver generally releases the covered lien rights immediately under its terms. For Florida roofing projects, Section 713.20(7) expressly permits a release exchanged for a check to be conditioned on payment of that check.
Use the correct progress-payment or final-payment release, clearly document any payment condition, and verify that the terms match the money actually being paid. For substantial disputes or customized release language, consult a Florida construction attorney.
