Metal roofing costs more upfront than asphalt shingle but outlasts it by decades and carries a Class A fire rating out of the box. West Covina Roofing Services installs standing-seam and corrugated panel systems on both homes and low-slope commercial buildings, where flat and commercial jobs in this metro typically run $6,250 to $18,000.
Standing-seam panels run in long, single-piece lengths from ridge to eave with no exposed fasteners; corrugated panels are cheaper, install faster, and show screw heads on the surface. Both shed water and debris better than shingle or tile, and both carry a Class A fire rating without any additional coating. The tradeoff is upfront cost — a metal roof is a bigger check than an asphalt reroof, and it stays that way for the life of the roof.
West Covina Roofing Services installs metal on flat and low-slope sections — additions, garages, and commercial buildings — and quotes it within the same flat & commercial roofing category the rest of that work falls under. Flat and commercial roofing jobs across this metro typically run $6,250 to $18,000; where a given building lands in that range comes down to square footage, insulation, and how many roof penetrations need flashing.
Is metal roofing worth it over asphalt shingle?
A shingle roof needs a full tear-off again in a couple of decades. A metal roof, kept up, doesn't. That's the entire case for it — the extra cost buys fewer roofs over the life of the house, not a better-looking roof. If the plan is to sell within five years, asphalt is the cheaper call.
Does a metal roof make the house louder in the rain?
Not once it's installed over solid decking with underlayment, which is how we install it. The noise complaint comes from open-frame agricultural buildings with panels fastened straight to purlins and nothing underneath — a residential retrofit with a plywood deck and synthetic underlayment doesn't sound different from a shingle roof in a storm.
Do you replace the gutters at the same time?
Most customers ask about it, and it's worth doing together. A metal roof sheds water faster and in a heavier sheet than shingle, and undersized or sagging gutters that coped fine under the old roof can overflow under the new one. We check the gutter run when we quote the roof rather than treating it as a separate call later.
How long does a metal roof last compared to asphalt shingle?
Decades longer — that's the entire value proposition of metal over shingle. It costs more to install, but you're not paying for a second full tear-off partway through the life of the house, the way a shingle roof eventually needs.
Can metal roofing go over my existing shingle roof?
Not the way we install it. Metal panels need a clean, solid deck and proper underlayment underneath to perform and to carry their fire rating — that means removing the old roofing first, not covering it.
Is metal roofing available for a flat or low-slope roof?
Yes — that's one of the categories we install it in most. Flat and commercial work in this metro is priced the same way, typically $6,250 to $18,000, with metal as one of the standard panel options for low-slope sections.
Do you install metal roofing on houses, or just commercial buildings?
Both. We install standing-seam and corrugated metal on additions, garages, and low-slope sections of houses, along with full commercial roofs — whichever part of the building needs it.
