Ribbed panels vs standing seam on a barn
Most barns and outbuildings get ribbed panels, the exposed-fastener kind screwed through the face into wood purlins. They go on fast, cover a lot of roof, and suit a barn's look. The trade-off is all those screws: each one has a rubber washer that eventually needs replacing.
Ask about steel gauge. Heavier gauge panels are stiffer, which matters when purlins are spaced wide, when snow drifts against a taller building, and when someone has to walk the roof later. Thin panels dent and oil-can more easily.
Standing seam metal roof panels hide their fasteners under the seams, so there's nothing to back out. They cost more and usually want a solid deck, which is why you see them on garages that match the house, on camps, and on barns people plan to keep a long time.
| Ribbed (exposed fastener) | Standing seam | |
|---|---|---|
| Fasteners | Through the panel face | Hidden clips under the seam |
| Upkeep | Screws and washers need checking | Very little |
| Usual base | Open purlins or solid deck | Solid deck |
| Typical use | Barns, sheds, pole buildings | Garages, camps, houses |
Rain noise and condensation under a metal barn roof
What's under the panels decides both. On open purlins with no insulation, you hear every rainstorm and every acorn. Fine for a hay barn, not for a garage with a workshop or a camp loft where people sleep. Panels over a solid plywood deck with underlayment sound about like any other roof.
Condensation is the bigger problem. When warm, damp air hits cold steel, it beads up and drips, and an unheated barn with animals or a garage where cars come in wet makes plenty of damp air. The fixes are underlayment over a solid deck, panels with a condensation-control backing when you're staying on purlins, and ventilation at the ridge and eaves. Sort this out before the panels go on, because it's much harder to fix after.
Barns in Saratoga County and Washington County
Drive the back roads around Gansevoort, Greenfield, Galway and Schuylerville, or east of the Hudson around Fort Edward and into Washington County farm country, and you'll see old barns in every condition. Plenty still have their first metal roof, rusted at the laps and leaking at the screws.
Before re-roofing an old barn, the installer should check:
- Rafters and purlins for rot, especially at the eaves
- Whether the roofline has sagged enough to need straightening
- What's underneath now (old metal, shingles, or bare boards)
- Where snow slides off and what it lands on
A sagging, uneven roof shows every wave through new panels, so some framing work up front pays off. If the old panels are sound and only the screws are failing, a metal roof repair may buy years before a full re-roof.
Garages, sheds and outbuildings
A detached garage is the easiest metal roof there is: simple shape, low height, quick job. Many owners match the house color or the barn's. Sheds and small outbuildings often use the same ribbed panels as the barn, cut to length.
Metal roofs for lake camps around Lake George
Camps around Lake George, Lake Luzerne and up the west shore toward Bolton Landing have their own problems: steep camp roads, tall pines dropping needles and limbs, and buildings that sit empty and snowed in from fall to spring. A metal roof sheds that snow on its own, which matters when nobody is there to shovel. Add snow guards for metal roofs over the door and the deck, and put solid decking under the panels if there's a sleeping loft under that roof.
Time the work around opening and closing the camp, and tell the installer about access in the quote request. Narrow, steep driveways change how materials get delivered.
