La Habra Commercial Roofing That Keeps You Open.

We are a north Orange County commercial roofer warehouses, shops, and small offices call when a flat roof starts leaking and the business cannot afford to shut down. TPO, torch-down modified bitumen, coatings, and fast flat-roof repair so a small problem stays small.

Who we work with

Flat-roof work for north OC businesses.

The industrial pockets off the 5, 57, and 91, the Brea and Fullerton business parks, and the La Mirada warehouse blocks are full of flat and low-slope buildings. Warehouses, light-industrial shops, retail strips, and small offices all sit under membrane or built-up roofs that age differently than a house. We keep them watertight and we schedule around your hours so the work does not stop your day.

Systems we install

Flat-roof systems we install and repair.

TPO membrane

Single-ply white TPO reflects the coastal sun, runs cooler inside, and welds into one continuous surface. A common choice for warehouses and retail across north OC.

Torch-down modified bitumen

Heat-welded modified bitumen builds a tough multi-ply layer for older low-slope decks. It holds up to foot traffic from HVAC and equipment service.

Roof coatings

A silicone or acrylic coating seals an aging flat roof and adds years before a full tear-off, often at a fraction of a replacement cost.

Flat-roof repair

Ponding, split seams, failed drains, and flashing at parapets and curbs are where flat roofs leak first. We fix the actual failure, not the stain inside.

Why it matters

A small leak can close a business.

On a warehouse or shop, water does not just stain a ceiling. It drips on inventory, shorts out equipment, and forces you to tarp off a section and lose floor space. Most flat-roof failures start small at a seam, a drain, or a rooftop unit, and a scheduled repair or coating now costs far less than an emergency tear-off and a week of lost operation later. We tell you straight whether yours is a repair, a coating, or a full replacement.

Questions

Straight answers.

What kind of commercial roofs do you work on?

Flat and low-slope buildings across north Orange County: warehouses, light-industrial shops, retail strips, and small offices. We install and repair TPO membrane, torch-down modified bitumen, and roof coatings, and we handle flat-roof leak repair and maintenance.

Can you work around our business hours?

Yes. We schedule the work so it does not shut your operation down, including early starts or staging the job in sections. We answer the phone ourselves in English and Spanish and confirm the plan with you before the crew shows up.

How much does a commercial flat roof cost in Orange County?

It depends on the size of the building, the system, and the condition of the deck. A coating to extend an aging roof costs far less than a full tear-off and replacement, and a targeted leak repair less still. We measure the roof and give a free written estimate with the real number before any work starts.

Our flat roof is ponding and leaking. Repair or replace?

Often a repair or a coating, not a full replacement. Ponding, split seams, and failed flashing at drains and parapets are usually fixable on a roof with life left in it. If the membrane is past saving we say so. We inspect it and tell you honestly which one your roof needs.

Are you licensed and insured for commercial work?

Yes. Pacific Roofing is a California-licensed roofing contractor, CSLB license 1092407, classification C-39, and insured. You can verify the license yourself on the CSLB website.
