How long does a metal roof last here?

Properly installed steel typically lasts 40 to 50 years — several times an asphalt roof. The failure point is almost never the metal itself; it is the fasteners and flashings, which is the main argument for standing seam over exposed-fastener systems.

What is the difference between standing seam and screw-down metal?

Exposed-fastener metal is held down by hundreds of screws with rubber washers, and those washers degrade in UV and need periodic re-torquing or they leak. Standing seam hides the fasteners under the seams, so there is nothing exposed to fail. It costs more up front and it is the reason metal roofs get a reputation for lasting decades.

Will a metal roof make my attic hotter in summer?

No, if the ventilation is right — and metal reflects more solar heat than dark asphalt, so it is generally cooler. What makes an attic hot is inadequate airflow, not the roofing material. We check that soffit intake matches the exhaust venting, because ridge vent without intake does very little under any roof.

Can you install metal over existing shingles?

Sometimes, where the deck is sound and the framing can take the load. But we inspect for rot first, because once panels are down the decking is hidden for decades. On most jobs tearing off is the better decision even though it costs more — you only get one easy look at that sheathing.

Does a metal roof stop ice dams?

It sheds snow considerably faster than asphalt, which helps. But ice dams are caused by heat escaping into the attic and melting snow that then refreezes at the cold eave, and metal does not change that. The fix is insulation and ventilation, not the roof covering.

Is a metal roof noisy in the rain?

Less than people expect on a properly built roof — solid decking with underlayment underneath deadens most of it. The drumming sound people remember usually comes from metal laid over open purlins on a barn, which is a different construction entirely.

Will metal roofing lower my insurance?

Some carriers offer a discount for metal or for impact-rated roofing and some do not. Worth a call to your insurer before choosing materials, since it can offset part of the cost over time.

Metal Roofing in Waterford Works, NJ

Metal roofing has gained real ground across South Jersey, and for sound reasons: a 40 to 50 year service life against 25 to 30 for asphalt, far better snow shedding, and reflectivity that keeps summer heat out of the attic rather than driving it in. The trade-off is up-front cost and the fact that it is less forgiving of poor installation than shingles are.

Standing seam versus exposed fastener. This is the decision that matters most. Screw-down panels are held by hundreds of exposed fasteners with rubber washers, and those washers degrade under UV. They need periodic re-torquing and eventually replacing, and every one is a potential leak. Standing seam conceals the fasteners beneath the seams, so there is nothing exposed to fail — which is why standing seam roofs last decades with little attention and screw-down roofs develop a reputation for weeping at the fasteners. Screw-down still makes sense on outbuildings, garages and barns where cost dominates.

Thermal movement is the thing installers get wrong. Metal expands and contracts substantially more than asphalt across a year of South Jersey temperatures. Standing seam systems accommodate this through clips that let the panel slide; fix a panel rigidly at both ends and it will either oil-can into visible waviness or work its fasteners loose. On retrofits over older homes we check deck flatness before anything goes down, because wide metal panels telegraph every dip in the sheathing in a way shingles simply do not.

Galvanic corrosion. Dissimilar metals in contact with water between them corrode. Steel panels tying into copper gutters or aluminium flashing need the right separation and the right fastener metallurgy. It is an unglamorous detail that shows up as staining and premature failure at the eaves a few years in.

Ventilation still applies. A metal roof does nothing to fix a badly ventilated attic. Ridge venting has to be paired with adequate soffit intake or humid summer air sits against the underside of the panels and condenses. We size intake and exhaust to the actual attic volume as part of the job rather than assuming what is there already works.

Permits. Roofing work in New Jersey falls under the state Uniform Construction Code, with permitting and inspection handled by your municipal construction office. Requirements vary by township and change over time, so we confirm what your municipality currently requires and pull the permit as part of the job.

Technician insight

The thing that catches people out with metal is deck flatness. Wide panels telegraph every dip and hump in the sheathing underneath, so a deck that looked perfectly acceptable under shingles can read as visible waviness once metal goes over it. On retrofits we check the deck plane before committing to standing seam, because the complaint afterwards is never about leaks — it is about how it looks in raking afternoon light.

Standing seam retrofit on a 1968 ranch

Ceiling stains appeared after a January thaw on a low-pitch screw-down metal roof. The butyl tape at the ridge had failed and several fastener washers had perished. We removed the old panels, corrected the deck plane, installed proper thermal clips and new ridge venting, and reinstalled in standing seam. No further leaks through the following winter.

How it works

1
Site Assessment

2
Material Selection
Standing seam or screw-down, gauge, coating and colour — chosen against sun exposure, tree cover, budget and how visible the roof is.
3
Preparation and Underlayment
Remove the old roofing, repair or replace decking, correct deck plane where panels would telegraph it, and install underlayment with ice-and-water shield at eaves and valleys.
4
Panel Installation
Panels set with clip spacing that allows for thermal movement, then flashing at every penetration, valley and ridge.
5
Final Inspection
Seams, fasteners and flashings checked, ventilation confirmed, debris removed and a walk-through with you.
