How to Price a Commercial Roof Coating Job | Reddit & LinkedIn

Start with accurate roof area, from plans, a measurement service, or a field measure, then add for vertical surfaces like parapets and curbs and for the detail work around penetrations, drains, and seams. Those details consume more material and far more labor per square foot than the open field, and underestimating them is a common way to lose money on a coating job.

Scope the condition at the same time. Note ponding areas, failed seams, blisters, and any signs of wet insulation below. The coating is only as good as what it goes over, so the scope has to separate simple coating from the repairs the roof needs first.

A roof coating is a system that depends entirely on the substrate beneath it. Cleaning, repairs, seam treatment, and priming are what make the coating adhere and perform, and they carry the warranty risk. Underprice the prep and you either eat the cost later or watch the coating fail and take the callback.

Price prep as its own honest line. Power washing, patching, reinforcing seams with fabric, and priming all take real labor and material. When the customer sees prep itemized, they understand they are buying a durable system, not just a coat of paint, and you are protected because the scope names exactly what condition the price assumes.

Material follows a simple formula: roof area divided by the coating’s coverage rate per gallon, times the number of coats the system requires, plus a waste factor and the detail material like primer and reinforcing fabric. Coverage rates and coat requirements come from the manufacturer’s specification for the specific system, so use their numbers, not a guess.

Silicone and acrylic systems have different coverage rates, coat counts, and costs, and some require a primer while others do not. Choosing the system is therefore both a performance decision and a pricing decision. Spell out the system on the quote so the customer is comparing like for like and so your material math is defensible.

Access and safety can be a major cost on commercial work. Roof height, how material and equipment reach the roof, and fall-protection requirements all add labor and cost that a residential mindset underestimates. Price staging, hoisting, and safety compliance explicitly.

Apply your markup on top of the full direct cost, set from your overhead and target profit, and add a contingency for hidden substrate problems that only appear once cleaning starts. A documented pre-coating inspection, with photos, supports both the contingency and any change order if the roof turns out worse than it looked from the parapet.

ContractShield lets you capture roof photos and measurements, describe the system and scope, and get an AI draft of labor, materials, and markup from your own templates in about 25 minutes total. You approve each line, and every line shows where its price came from, so the numbers stay yours.

Photos attach to the project and the milestones, which matters on coating work where the pre-coating condition is the warranty basis. The customer accepts online, milestone payments are built in, and automatic collections chase any past-due balance, so the tool that scoped the roof also gets you paid.
