Metal Building vs Wood Garage: What Lasts Longer?

A stick-built wood garage is what a lot of folks grew up with. Steel garages have become a common choice over the years. If you’re deciding between the two, the question usually comes down to this: which one will hold up better with less work?

Here’s how they compare.

How they’re built

A wood garage is framed on site with lumber: studs, rafters or trusses, sheathing, and then siding and roofing. It’s built piece by piece by a framing crew.

A steel garage uses a manufactured steel frame with steel roof and wall panels. The parts are made by the manufacturer, delivered, and assembled on site. Our buildings are delivered, set, anchored, and checked before the crew leaves.

What wears out a wood garage

Rot

Wood and water don’t get along. Leaky roofs, splashing rain at the base of walls, and ground moisture all lead to rot over time. Sill plates, the bottom of the siding, and roof decking are common trouble spots.

Termites and other pests

Termites, carpenter ants, and carpenter bees can damage wood framing, often out of sight until the damage is done.

Paint and siding upkeep

Wood siding needs regular painting or staining to keep moisture out. Shingle roofs wear out and need replacing over time.

Warping and settling

Lumber shrinks, twists, and moves with the seasons. That can lead to sticking doors and cracks.

What wears out a metal garage

Steel has its own enemies, and it’s only fair to point them out.

Rust

Scratches, standing water, and damaged coatings can let rust start. Keep an eye on panels and touch up scratches.

Condensation

Without the right insulation and ventilation, steel buildings can sweat on the inside. That can lead to rust on stored items. Our post on insulation options covers how to deal with it.

Loose fasteners

Over time, check screws and fasteners and replace any that have worked loose or lost their seal.

The good news is that steel doesn’t rot, warp, or feed termites, which are the problems that do the most damage to wood garages.

Durability in storms

Both can be built to handle wind and snow, but it depends on how they’re designed and built. Our steel buildings are certified for local wind and snow loads, with engineered drawings available. The vertical roof, which about 80% of our customers choose, sheds rain and snow instead of letting it sit. Read more in our post on wind and snow load ratings.

Fire

Steel framing and panels don’t burn like a wood frame does. That’s worth thinking about if you’ll be welding, running heaters, or storing fuel.

Build time

A wood garage is framed and finished on site, which takes a crew a good bit of time, and weather can stretch it out. A steel building’s parts are made ahead of time, so once the site and foundation are ready, the install goes quickly.

Looks

Some people prefer the look of a wood garage to match their house. Steel buildings come in a range of colors and roof styles, and options like wainscot and boxed-eave or vertical roofs give them a more finished look.

Quick comparison

	Steel garage	Wood garage
Rot	No	Yes, over time
Termites and pests	No	Yes
Fire	Frame does not burn	Frame can burn
Main upkeep	Watch for rust, check fasteners	Paint, roof, rot and pest repairs
Install	Quick once site is ready	Framed on site, takes longer
Wind and snow	Certified for local loads	Depends on builder

Cost

Costs depend on size, finishes, site prep, foundation, and your local market, so we won’t put numbers on it here. The best comparison is a quote for the same size, height, and doors from both. Think about long-term upkeep too, not just the day-one price. See what affects the price of a metal building.

So which lasts longer?

With basic care, a steel garage avoids the biggest problems that wear down wood: rot, termites, and warping. A wood garage can last a long time too, but it usually needs more regular upkeep to get there.

If you want a garage that goes up quickly and doesn’t need painting, take a look at our metal buildings. Enclosed garages also qualify for our rent-to-own program.

Common Questions

Does a metal garage last longer than a wood garage?

A steel garage avoids rot, termites, and warping, which are the biggest causes of wear on wood garages. With basic care, it holds up well with less upkeep.

What maintenance does a metal garage need?

Watch for scratches and rust, keep water from sitting against panels, check fasteners, and control condensation with insulation and ventilation.

Is a metal garage faster to build?

Usually. The parts are made ahead of time, so once the site and foundation are ready, the install goes quickly.

Can I finance a metal garage?

Enclosed garages qualify for our rent-to-own program. Open carports are not eligible.
