Waterproofing Contractor
Overhead Rate.

Waterproofing subcontractors carry overhead driven by specialized chemical systems, manufacturer certification requirements, and the warranty administration that waterproofing guarantees require.

Overhead Benchmarks — Waterproofing Contractors — By Revenue Band

What Normal Looks Like
At Your Revenue Level.

These benchmarks are drawn from SPM's work with commercial waterproofing contractors and industry data. Calculate your actual overhead rate — total G&A expenses divided by total revenue for the trailing 12 months — and compare to your revenue band below.

How to use this data: If you're above the top of the range, specific categories need review. If you're below the bottom, you may be underinvesting in systems and staff. Use the benchmark as a target range, not a single number.

Trade note for Waterproofing Contractors: Below-grade waterproofing contractors carry different overhead profiles than roofing waterproofing contractors. Below-grade work involves more substrate preparation and drainage composite system complexity. Roofing waterproofing involves more weather-dependent scheduling and warranty administration. Both carry premium overhead relative to trade averages due to the performance guarantee expectations associated with waterproofing systems.

Why Overhead Rate Gets Off Track

Three Reasons Your
Overhead Is Drifting.

01

Manufacturer Certification Costs Are Scattered

Maintaining applicator certifications across multiple waterproofing system manufacturers — BASF, Tremco, Grace, Henry — involves training, certification fees, and continuing education that's often scattered rather than consolidated.

02

Warranty Administration Overhead Is Underestimated

Waterproofing manufacturers require post-installation inspections, documentation, and certification before issuing warranties. This warranty administration overhead is a real cost that must be priced into bids — not absorbed after the job closes.

03

Chemical Storage and Handling Overhead

Waterproofing chemical storage requirements — temperature control, hazmat compliance, shelf life management — create overhead that's often underestimated in overhead rate calculations for smaller operations.

How SPM Manages It

Overhead Rate as a
Managed Number.

Certification Cost Consolidation

SPM tracks all manufacturer certification and training costs as a consolidated overhead category in ControlQore — giving clear visibility into the true cost of maintaining multi-manufacturer applicator capability.

Warranty Administration Cost to Jobs

Post-installation inspection labor, warranty documentation preparation, and manufacturer certification fees for specific projects are coded to those jobs in ControlQore — not to overhead. Warranty administration is a project-specific cost.

Chemical Overhead Tracking

Chemical storage, temperature control, and hazmat compliance costs are tracked as a dedicated overhead category — supporting accurate chemical handling overhead pricing in bids and revealing the true cost of maintaining chemical storage compliance.

Common Questions

Straight Answers.

How do I calculate my overhead rate?
Add up every expense that isn't a direct job cost for the trailing 12 months — office staff, rent, insurance, equipment payments not allocated to jobs, vehicles, software, marketing. Divide by total revenue for the same period. That percentage is your overhead rate. Compare it to the benchmark for your revenue band above.
Does SPM serve waterproofing contractors at all revenue levels?
SPM's direct engagement covers $1M–$12M in revenue. The benchmark data on this page covers the full revenue spectrum for reference. For contractors above $12M, SPM can make the right introduction to firms that specialize at larger scale.
