Metal roofing costs more upfront than asphalt but often lasts decades longer if the fasteners and coating are specified correctly — standing-seam hides every fastener under a concealed clip, while exposed-fastener corrugated panels are cheaper but need their gasketed screws re-torqued or replaced over time. Inglewood Roofing Services installs and services both across the 19 communities it covers.
Standing-seam and exposed-fastener corrugated are the two systems homeowners actually choose between. Standing-seam uses concealed clips so no screw head is ever exposed to weather, which is why it costs more and needs almost no maintenance over its life. Corrugated panels are fastened straight through the metal with gasketed screws — cheaper to install, but those gaskets compress and harden with age and need periodic re-torquing or swapping out.
Whether a metal roof needs a full tear-off or can go over what's already there depends on what's underneath. Sound plywood decking can sometimes take furring strips and a new metal layer on top; a compromised deck, or a roof that's already a second layer, means tear-off is the only option. Inglewood Roofing Services checks the deck before quoting either way rather than pricing a re-cover sight unseen.
What actually fails on a metal roof first?
It's rarely the panels themselves. On exposed-fastener corrugated systems, it's the gaskets under each screw head — sun and heat cycling harden and crack the rubber over the years until water finds a path around the shaft. Standing-seam mostly avoids this because the fasteners are hidden under the seam, not driven through the face of the panel.
The other common failure point is where the metal meets something that isn't metal — a chimney, a vent pipe, a wall — since those transitions still rely on flashing details rather than the panel system itself.
- Exposed-fastener gaskets — the most common single repair item on corrugated roofs
- Penetration flashing around vents, pipes, and skylights
- Sealant at ridge and hip caps
- Fastener backout where panels have expanded and contracted over many heat cycles
Is metal roofing worth it over asphalt shingles?
The honest answer is: it depends on the roof. Metal costs meaningfully more upfront than an asphalt reroof of the same size, and that premium is easiest to justify on a low-slope section, where shingles perform worst and fail soonest, or on a roof getting replaced anyway rather than one that's still holding up fine.
If the existing shingle roof still has useful life left in it, there's no reason to tear it off early just to switch materials — that's not a call Inglewood Roofing Services will push a customer into.
Can a metal roof go directly over my existing shingles?
Sometimes — if the deck underneath is sound and this isn't already a second roofing layer, furring strips can go over the shingles with the metal fastened to that. If the deck is compromised or there are already two layers down, the old roofing has to come off first.
Do metal roofs make more noise in rain?
Not when they're installed correctly. Installed over solid decking with underlayment underneath — which is standard practice, not an upgrade — a metal roof isn't noticeably louder than shingles in rain.
