Metal roofing is no longer unusual on South Bay streets, and neither is the question of whether the extra cost pays off. The honest answer has two halves: what you pay today, and what you pay again later. This post sets out both for homeowners weighing metal against shingles. If you want to see how we handle the material, our metal roofing page describes it.
How much does a metal roof cost compared with shingles?
The spread in published numbers is wide because "metal" covers very different products. This Old House's 2026 guide breaks per-square-foot ranges out by type:
| Metal type | Published range per sq ft |
|---|---|
| Sheet metal panels | $4 to $6.50 |
| Metal shingles | $7 to $22 |
| Corrugated, exposed fasteners | $4 to $26 |
| Cut-to-size standing seam | $9 to $30 |
For asphalt, HomeBlue's 2026 data shows about $5 to $8 per square foot installed. Different guides count different things, such as material only or full installed cost, so the figures are not perfectly comparable. All of them are market data and not a quote from Crown Trim.
What makes a metal roof price jump?
- Panel style. Standing seam with hidden clips costs more than exposed-fastener panels.
- Roof complexity. Hips, valleys, dormers and skylights each mean custom trim.
- Underlayment. Metal needs the right underlayment for the climate and the roof pitch.
- Tear-off. Removing existing shingles, or old metal, is a separate line.
- Details. Flashing, ridge, gutters and solar panel removal and reinstallation add scope.
One Google reviewer described a roofer who removed an old metal roof and put on brand new panels in two days. Speed varies with the roof, but a clean scope helps any job move along.
How long do metal and shingle roofs last?
This Old House's 2026 guide gives metal about 40 to 70 years and asphalt about 15 to 30. In Southern California, sun is the main wear factor for shingles. Metal shrugs off sun but has its own weak points: sealants at penetrations, fasteners that back out, and finish damage near the coast where salt air attacks scratches. Both roof types need an inspection once in a while. Our post on how long roofs last in Southern California goes deeper on that.
Is a metal roof worth it?
It is worth it when you will own the house long enough for the longer life to matter, or when the shape of the roof suits metal. It is a harder sell if you plan to sell within a few years, since there is no reliable published number for resale gains. Think in cost per year of life, not just the day-one price, then check that against how long you actually plan to stay.
Also check heat and fire ratings. Reflective finishes are rated by the Cool Roof Rating Council, and fire ratings apply to a full roof assembly, not just the panel. Ask for the rating of the exact system quoted. In areas such as the Palos Verdes Peninsula, fire rules are stricter, and the rules depend on the address, so confirm them with your city or county.
What we look at when homeowners ask about metal
This is the expert-insight part. We look first at the roof you have: its pitch, deck condition and number of penetrations. A complicated roof full of valleys and chimneys erodes the cost advantage of any single material. We also check whether the house can take the weight and fastening method you are considering, and whether gutters and fascia are in shape to match a new roof. Then we show photos of the deck and explain how metal and shingle quotes would differ.
How do salt air and wind change the metal choice near the coast?
Metal behaves differently on a street a mile from the beach than on an inland one. Salt air attacks exposed fastener heads, cut panel edges and any scratch that breaks the finish, so coastal homes in places like Redondo Beach and Hermosa Beach need a closer look at coating, fastener type and trim. Our post on salt air and roofs in the beach cities covers the corrosion signs.
Wind and sun cause a different problem. Metal expands and contracts through the day, so exposed screws can back out over the years, which is one reason concealed-clip standing seam costs more than exposed-fastener panels. Santa Ana gusts also test the edges, ridge and trim more than the field of the roof. Ask each bidder to name the finish, the fastener type and the edge details in the quote, so a low number is not hiding a lighter system.
Does a metal roof change heat, noise and maintenance?
Heat is the question we hear most. Metal can reflect more sunlight than dark shingles, particularly with a reflective finish, but the real result depends on color, attic ventilation and insulation. A ventilated attic matters more than the surface in many homes, so check it with any new roof. Cool-roof ratings come from the Cool Roof Rating Council, and the rules that apply to your address are set by your city and the California Energy Commission, not by us.
Noise depends on the deck and insulation beneath the panels. Maintenance is lower than most expect but not zero. Look at sealants, fasteners and scratches in the finish every year or two, especially near the coast.
What should a side-by-side bid for metal and shingles include?
Give each roofer the same photos and the same instructions, then check that every bid lists:
- The same tear-off assumption, and what happens if the deck is soft
- Underlayment type under each material
- Flashing, drip edge and vent details, not just panels or shingles
- Gutter, fascia and solar panel work, if either applies
- Permit handling and who books the inspection
- Warranty documents to read before signing, since material and workmanship terms differ (our post on roof warranties explained covers the difference)
If you are also pricing asphalt shingle roofing, ask for both options in one visit. A gap that disappears when the scopes match was never a real gap.
Next steps
Ask each roofer for itemized quotes on both materials, with the same tear-off and flashing scope. Check that roofer's license on the CSLB site. As a roofing contractor in Torrance, we give free estimates and ask about financing at your estimate. Bring photos of any style you like, and we will tell you how it fits your roof.
