Roof Coating Contract Payment Terms: Deposits, Progress Payments and Holdbacks Commercial Owners Should Expect

On a commercial roof coating job, a deposit of roughly 10% to 33% of the contract is common, with the balance split into progress payments and a final payment tied to completion. A request for the full amount up front is the one term to refuse. Everything else is negotiable, and how the payments are structured tells you a lot about the contractor.

Most owners compare coating bids on price per square foot and never read the payment schedule. That’s a mistake, because the schedule decides who carries the risk if the job stalls, the weather turns or the paperwork never shows up. Here is what a sensible schedule looks like on a silicone restoration, where the whole project usually takes just 1 to 3 days of installation.

How Much Deposit Is Normal?

Material is the real up-front cost on a coating job. Silicone is ordered by the pail or drum for your specific roof area, so a contractor has a legitimate reason to ask for money at signing. The ranges commonly cited for roofing work run from about 10% to one-third of the contract price, and many owners land in the 20% to 33% range on a coating job where materials are a large share of the total.

• Reasonable: a deposit that roughly covers materials, stated in writing, with the balance due at defined milestones.
• Worth negotiating: anything above one-third, especially from a contractor you haven’t worked with before.
• Walk away: 100% before work starts, “discounts” for paying in full, or pressure to pay in cash.

Rules on deposits vary by state and mostly target residential work, so confirm what applies to your property and read your own contract. If a contractor can’t name what the deposit buys, that’s your answer.

Progress Payments and Holdbacks on a 1-3 Day Install

Because a coating install is short, payment schedules are simpler than a tear-off. A typical structure looks like this:

• At signing: deposit, with the material order placed.
• On completion of installation: the bulk of the balance, released after the crew has finished and cleaned up.
• Holdback: a final slice, often around 10%, held until the walkthrough, punch list and paperwork are done.

Larger jobs on big warehouse roofs may add a mid-project milestone, for example after prep and seam work is complete and before the final coat. The point of a holdback, sometimes called retainage on commercial work, is to keep a small amount of leverage in your hands until every item is actually finished. Withhold only an amount proportional to open items, not the whole balance over a minor touch-up.

Lien Waivers: The Paper That Protects You

If a contractor doesn’t pay its material supplier or crew, some states let those parties file a lien against your building, even though you already paid the contractor. The fix is simple: ask for a lien waiver with each payment. A conditional waiver comes with a progress payment and takes effect once the payment clears. An unconditional waiver comes with the final payment. A contractor who balks at providing waivers is giving you information.

Tie Final Payment to the Warranty Paperwork

The last payment should be released only when the work, the paperwork and the walkthrough are all done. On a silicone restoration that means more than a clean roof:

• Walkthrough completed and punch-list items closed.
• Manufacturer warranty application submitted, and workmanship warranty delivered in writing.
• Documentation of the pre-coating inspection and coating thickness, which the warranty can depend on.
• Unconditional lien waiver from the contractor, and from major suppliers if your contract requires it.

A 15 to 20 year warranty is only as good as the paperwork behind it. Our posts on certified applicator programs and how to read a coating quote explain what to check before you sign.

Know the Number Before You Negotiate the Terms

Payment terms matter most when you already know what the job should cost. A silicone restoration typically runs $3 to $6 per square foot against $8 to $15 per square foot for tear-off replacement, which can save 50% to 70% and keep your tenants working through a 1 to 3 day install.
