DeHart Roofing handles commercial projects from single-unit retail buildings to large multi-family complexes across the Modesto–Turlock corridor. That means warehouses in Ceres, retail in Modesto, and HOA upkeep in Salida. The work covers full commercial roof replacement, retrofit, and tie-ins to commercial roof repair on active-leak buildings.
Under new local ownership since 2026, every project runs on flat-rate pricing, a written scope of work, and strict accountability standards. One crew, one foreman, one bid — no rotating subs, no change orders.
Commercial roofing systems we install
7 Systems · Side-By-Side
We install every major commercial roof system on the U.S. market. The right choice depends on four things: holding period, building type, budget, and Title 24 compliance. TPO is our most-recommended pick for Stanislaus County buildings.
Single-ply membranes: TPO, EPDM, PVC
Single-ply means one layer of roofing membrane, either heat-welded or adhered (glued down). TPO, EPDM (a synthetic rubber), and PVC (a vinyl membrane) are the dominant commercial roof category for Stanislaus County warehouses and HOAs. All three are Title 24 ready and last 15–30 years.
Built-up & modified bitumen systems: BUR, Mod Bit
These are asphalt-and-felt legacy systems. We install Mod Bit on smaller flat roofs. We use BUR (built-up roofing) for repair retrofits, not new installs.
Metal & sprayed-in-place: Standing Seam, SPF
Long-life standing seam metal suits agricultural and industrial buildings. SPF (spray polyurethane foam) suits irregular shapes and retrofit insulation.
| System | Cost / Sq Ft | Lifespan | Fire Rating | Title 24 | Best For |
|---|---|---|---|---|---|
| TPORecommended | $6.50–$10 | 15–25 yr | Class A | ✓ | Warehouses, retail |
| EPDM | $5.50–$9 | 20–30 yr | Class A | ◐ | Multi-family, traditional flat |
| PVC | $7–$12 | 20–30 yr | Class A | ✓ | Restaurants, labs, chem-resistant |
| BUR | $5–$8 | 15–25 yr | Class A | ✗ | Legacy flat, repair retrofit |
| Mod Bit | $5–$8 | 15–25 yr | Class A | ◐ | Smaller flat roofs |
| Standing Seam | $9–$18 | 40–60 yr | Class A | ✓ | Long-life, agricultural, modern industrial |
| SPF | $4–$8 | 20–30 yr | Class A | ✓ | Irregular shapes, retrofit insulation |

Our commercial roofing process
Every commercial job runs the same five-step process. No surprises, no scope creep.
Initial Assessment
Clayton or a project lead walks the roof, measures the system, documents condition, and flags any deck issues to address before install.
Written Bid
Flat-rate written estimate with itemized scope, system spec, and timeline — within 48 hours. No verbal estimates, no surprise change orders.
Schedule & Permits
We pull all required permits and coordinate around your operation. For occupied buildings, we set noise hours, parking plans, and tenant comms.
Installation
Our own crews, held to strict install standards — not day-labor subs. A supervisor is on-site daily. We do not leave a job half-done.
Punch & Closeout
Joint walkthrough, fix any items that miss spec, then deliver warranty documentation and permit sign-off before we call the job complete.

Title 24 cool-roof compliance for Stanislaus County
CA Title 24 · Climate Zone 12
Stanislaus County sits in California Climate Zone 12. Title 24 Part 6 requires low-slope commercial roofs to meet a minimum aged Solar Reflectance Index (SRI) — a measure of how well the roof reflects heat. The roof must also carry CRRC-listed product documentation. Here's what each system clears:
| System | Aged SRI | CRRC Listed | Notes |
|---|---|---|---|
| White TPO | 0.64+ | Yes | Default compliant pick |
| White PVC | 0.70+ | Yes | Highest reflectance |
| Standing Seam Metal | 0.55+ | Yes | Cool-coat finish required |
| SPF + cool-coat | 0.60+ | Yes | Topcoat sold separately |
Dark EPDM and BUR require add-on insulation or a cool-coat to clear Climate Zone 12. We document compliance in the bid.
Commercial storm damage & insurance claims
Storm & Insurance
When hail or high wind hits a low-slope commercial roof, two clocks start at once: water intrusion and your insurance filing window. DeHart documents the damage adjuster-ready — dated photos, measurements, and a clear repair-or-replacement scope — so property managers and owners can file a clean claim and keep tenants dry. We meet your insurer's adjuster on-site, scope the work to the policy, and tarp emergencies the same day.

Why choose DeHart for your commercial project
Most commercial buildings in Stanislaus County run on three systems. Warehouses around Modesto use TPO. Older Turlock HOAs use ballasted EPDM — where loose stone weighs the membrane down. Smaller flat roofs in Ceres and Salida use mod bit. Clayton bids the right system for the building, not a one-size pitch. Five reasons commercial property managers route projects to DeHart:
Stanislaus heritage. Roofing business buildings in this county since 1975.
New local ownership. Rigorous accountability standards on every commercial project.
Budget-tier option for HOAs and property managers on fixed budgets.
Clayton handles commercial sales directly. No rotating reps, no call center.
Insurance liaison with State Farm, Travelers, Zurich, and Mercury.
