**The material list for a metal roof has eight parts: the metal panels, their paint finish, the underlayment, clips and fasteners, trim and flashing, closures, sealants, and the ventilation parts at the ridge and eaves.** In Woodland Hills three local conditions decide which version of each item performs: long, very hot summers, a cool-roof rule for climate zone 9, and Class A fire requirements where a home sits in a Very High Fire Hazard Severity Zone. For a metal roof estimate with the full material list written out, call NEMA Roofing at [818-528-6412](tel:818-528-6412).

## What goes on a metal roof, layer by layer?

| Item | What it is | What performs in Woodland Hills |
| --- | --- | --- |
| 1. Panels | Standing seam (concealed clips), ribbed or corrugated (screwed through the face), or stone-coated steel shingles, shake or tile | Aluminum-zinc coated steel is the usual metal inland; aluminum, zinc and copper are options for special designs |
| 2. Finish | Factory paint system on the panel and matching trim | A color with Cool Roof Rating Council (CRRC) aged ratings that meet the climate zone 9 values |
| 3. Underlayment | The water barrier over the roof deck | A high-temperature underlayment rated for metal; in fire zones, one listed as part of a Class A assembly |
| 4. Clips and fasteners | Clips that hold standing seam panels; screws with sealing washers for exposed-fastener panels and trim | Clips that let panels slide through big daily temperature swings; EPDM washers; fasteners compatible with the panel metal |
| 5. Trim and flashing | Drip edge, eave and rake trim, ridge cap, valley, wall and chimney flashing, pipe boots | The same metal and finish as the panels; corrosion-resistant valley metal over a cap sheet where the fire code applies |
| 6. Closures | Foam or metal pieces that fill the gaps under panel ribs at the eave and ridge | Bird stops at the eaves to keep leaves, pests and embers out of the airspace under the panels |
| 7. Sealants | Tape and sealant in laps, trim joints and penetrations | Non-curing butyl hidden inside joints, polyurethane where exposed; nothing rigid on joints that must move |
| 8. Ventilation | Ridge vent and soffit intake | Balanced airflow to carry summer heat out of the attic |

A good estimate lists each of these with the product name, thickness and color, so two bids can be compared line by line.

## How hot does it get, and why does that shape the list?

NOAA’s 1991 to 2020 climate normals for the Woodland Hills Pierce College weather station show an average August high of 97.4 F, about 115 days a year at or above 90 F, and about 35 days at or above 100 F. On an August day the air alone swings from about 61 F at night to 97 F in the afternoon, and a panel in full sun runs hotter still. Three items on the list answer that heat:

- **Clips and fixing.** The U.S. Department of Defense roofing criteria (UFC 3-110-03) size standing seam clips for a panel temperature swing of 200 F, and 220 F for dark colors, and fix each panel at one point so the rest can slide.
- **Underlayment.** A high-temperature underlayment is made to stay stable under hot metal; check that the product sheet rates it for metal roofing.
- **Ventilation.** A vented ridge with clear soffit intake lets the attic shed heat that the roof does not reflect.

## Which finish meets the Woodland Hills cool-roof rule?

Both Woodland Hills ZIP codes, 91364 and 91367, fall in climate zone 9, where the 2025 Title 24 energy code sets a floor for any pitched-roof replacement covering more than half the roof: the finish’s aged reflectance must reach 0.20 with emittance of 0.75, or its SRI must reach 16. Exceptions exist, such as a well-insulated ceiling, a radiant barrier, an attic with no ducts, or insulation laid over the deck. The Los Angeles Department of Building and Safety (LADBS) asks for a CRRC-certified product on residential roof replacements over 50 percent of the roof area. The California Energy Commission notes that cool roofs come in a wide range of colors, including dark and vibrant shades, so check the aged values for the exact color on the list rather than assuming only white qualifies. Our page on [cool roofing in Woodland Hills](https://nemaroofing.com/cool-roofing/cool-roofing-woodland-hills-benefits/) explains the ratings.

## What does the fire zone add to the list?

The City of Los Angeles fire zone map shows Very High Fire Hazard Severity Zone areas within both Woodland Hills ZIP codes, and LADBS requires a Class A roof covering in those zones. Metal does not burn, but over a wood deck the Class A rating belongs to the tested assembly, so the underlayment on the list has to be the one named in that assembly’s listing. California’s 2025 Wildland-Urban Interface Code, for buildings in wildland-urban interface areas, adds details that belong on the material list:

- Where the panel profile leaves an airspace over a wood deck: a 72-pound mineral-surfaced cap sheet over the deck (or at least an inch of noncombustible board), or a listed Class A underlayment; bird stops at the eaves; hip and ridge caps closed off against fire and embers.
- Valley flashing of corrosion-resistant metal at least 0.019 inch thick (26 gauge galvanized) over a 36-inch-wide cap sheet running the full length of the valley.
- Noncombustible gutters with an approved way to keep leaves out.

Check your address on the city’s fire zone map before the materials are ordered; the list changes if it falls inside a zone.

## Which metal should be on the list?

- **Coated steel.** Steel with a 55 percent aluminum-zinc coating (Galvalume) and a factory paint finish is the standard inland choice. The UFC notes it does less well in direct salt spray, which is not a Woodland Hills concern.
- **Aluminum.** It does not rust and is often the better pick right on the coast, but it costs more and moves more with heat; on an inland Valley home its main advantage, salt resistance, matters less.
- **Zinc and copper.** Architectural metals chosen for their look; they need installers who work in soft metals and they must be kept apart from steel and aluminum.

Whichever metal you choose, the trim, flashing and fasteners should be compatible with it; the UFC warns against dissimilar metals and says steel and aluminum should never touch without a separator.

## What about older Woodland Hills homes?

Census estimates put the median year built at 1967 for homes in ZIP 91364 and 1975 in 91367, so many roofs going to metal sit on decks and attics that are 50 or more years old. Plan for two line items that do not show up on a product sheet: replacement of soft or damaged sheathing after tear-off (ask for it as a unit price), and attic ventilation or insulation upgrades, which can also qualify the roof for a cool-roof exception. Most reroofs with Class A or B coverings under 6 pounds per square foot over solid sheathing qualify for an LADBS Express Permit; the panel’s data sheet shows its weight.
