Commercial Roof Inspection and Maintenance in Torrance, CA
Torrance holds one of the largest industrial bases in the South Bay, from the refinery on its northern edge to aerospace suppliers, auto company campuses and the business parks around Torrance Airport.
What kinds of commercial buildings are in Torrance?
Torrance's commercial buildings span refinery support facilities, aerospace and automotive manufacturing, corporate campuses, a regional mall and a large inventory of business park flex space.
Much of the manufacturing stock went up between the 1950s and 1980s, while the corporate campuses near the I-405 were built from the 1980s onward.
- Del Amo Boulevard and Crenshaw Boulevard: manufacturing plants and the Del Amo Fashion Center
- 190th Street corridor: the refinery, industrial suppliers and truck yards
- Torrance Airport business parks: aviation hangars, flex buildings and small plants near Pacific Coast Highway
- Maple Avenue and Lomita Boulevard: older light industrial and machine shops
| Building type | Common roof system | Typical age | What Torrance does to it |
|---|---|---|---|
| Aerospace and auto plants | Built-up roof or modified bitumen | 25 to 45 years old | Salt air on metal flashings and curbs |
| Corporate campus offices | PVC or TPO | 10 to 30 years old | Dense mechanical penetrations |
| Airport flex buildings | Coated built-up roof or spray foam | 20 to 40 years old | Coating wear from coastal UV and fog |
What does the Torrance climate do to a flat roof?
The Torrance climate is mild and coastal, with a marine layer most mornings from May through July and salt air carried a few miles inland from the Redondo shoreline.
Moisture from the fog condenses on cool roof surfaces overnight, and that repeated wetting speeds corrosion of fasteners, drain rings and rooftop unit housings.
How often should a Torrance commercial roof be inspected?
A Torrance commercial roof should be inspected twice a year, spring and fall, with a closer look at metal components on buildings west of Hawthorne Boulevard.
Buildings nearer the coast show corrosion earlier, while plants near the refinery also collect airborne residue on their membranes. Our commercial roof inspection page explains what each visit covers.
What does a maintenance program cost in Torrance?
A maintenance program for a 180,000 square foot aerospace and manufacturing plant in Torrance costs $39,600 to $45,000 a year on our Protect program, priced at $0.22 to $0.25 per square foot with a $2,500 minimum.
Protect fits most Torrance plants and campuses because two visits a year keep pace with coastal corrosion and the frequent mechanical changes these tenants make. Every tier and what it includes is on the maintenance programs and pricing page.
