What to expect
What a metal roofing visit covers
A roof inspection verifies your existing roof deck and underlayment.
If recovering an old asphalt shingle roof, we remove shingles and debris, then install ice-and-water shield around eaves and valleys.
Synthetic underlayment across the substrate protects against water intrusion.
Standing-seam metal panels, exposed-fastener panels, and corrugated panels fasten through the substrate into the truss structure using ring-shank nails or screws driven straight through the metal into decking.
Fasteners must penetrate plywood or OSB to hold properly against wind uplift.
Flashing at chimneys, step flashing where the roof meets a sidewall, counter-flashing at dormers, and drip edge at the rake and eave seal transition points.
These details are where most leaks start if not installed or re-sealed properly.
A ridge cap covers the peak.
Ventilation openings in the soffit and ridge vent create an insulation air layer that lets attic moisture escape, reducing summer heat buildup and extending the life of your roof frame.
San Jose's winter rain storms test flashing detail and coating integrity.
A metal roof costs $12–18 per square foot installed, depending on material (aluminum, steel, or standing-seam), gauge, and finish type.
Installation typically takes 3–7 days depending on roof size and complexity.
Metal roofing lasts 40–50 years with minimal maintenance, compared to asphalt shingles, which degrade under UV light and granule loss after 15–20 years.
A proper installation with correct flashing, underlayment, and ventilation extends lifespan in San Jose's climate.

What drives the price
Metal pricing is driven by panel type, substrate condition and the detailing around penetrations.
Before you book
Fees for metal roofing in San Jose are set by the provider you choose, not by this site.
Ask for the number and the deliverable in writing before anyone starts.
- Panel and profile
- Standing seam, exposed fastener and metal shingle systems differ widely in material and labour cost.
- Substrate and tear-off
- Metal can sometimes go over existing roofing, but only where the structure and decking allow. That decision changes the price.
- Detailing
- Valleys, chimneys, skylights and wall junctions need formed flashings. On metal, details are where leaks start.
- Finish and warranty
- Paint systems and their warranties vary by product. Ask for the manufacturer documentation, not just a colour chart.

Compare Written Scopes
For metal roofing: each provider should give an itemised scope covering materials, labour and timeline. Compare like for like rather than headline totals.

Questions
Metal Roofing in San Jose
How long does a metal roof last in San Jose?
Standing-seam metal roofs typically last 40–50 years with minimal maintenance.
San Jose's dry summers and winter rain storms are easier on metal than on asphalt shingles, which degrade under UV and granule loss after 15–20 years.
A proper installation with correct flashing and ventilation extends longevity even further.
What's the difference between standing-seam and exposed-fastener metal panels?
Standing-seam panels hide fasteners inside raised seams, making them more water-tight and less prone to fastener corrosion.
Exposed-fastener panels are less expensive but require more frequent inspection and re-sealing.
For San Jose's winter rain storms, standing-seam is the better choice for homes in flood-prone areas.
Do I need to replace the roof deck when installing a metal roof?
Not always. If your existing roof deck is sound with no rot or sag, we can install synthetic underlayment directly over it.
But if the wood is soft, rotten, or settling, we'll replace plywood sheathing and OSB where needed.
A roof inspection tells us what's required before we quote the job.
Can metal roofing handle hail damage in San Jose?
Metal roofs resist hail better than asphalt shingles, but large hail can dent panels or break fasteners. Stone-coated steel panels offer extra dent resistance.
If ice dams form during winter thaw, proper ridge ventilation and ice-and-water shield at eaves prevent water intrusion.
We inspect for damage after storms and file insurance claims when needed.
How much does metal roofing cost per square foot?
Metal roofing typically costs $12–18 per square foot installed in San Jose, depending on material (aluminum vs. steel), gauge, and finish type (PVDF or SMP coating).
Asphalt shingles cost less upfront ($8–12/sq ft) but require replacement twice as often. Metal's longer lifespan often makes it cheaper over 50 years.
How long does a metal roof last?
It depends on the metal, the coating and the detailing. Ask for the manufacturer’s warranty document for the specific product proposed, not a general figure.
Is a metal roof noisy in rain?
With solid decking and insulation, most people find it comparable to other roofing. Ask how the assembly will be built on your roof.
Can metal go over my existing shingles?
Sometimes, if the structure and decking allow it. That decision needs an inspection, and it changes both cost and roof height at the edges.
