Is a metal shed better than a wooden one?

Our old wooden shed has finally rotted through and I'm tempted by a metal one this time. Do they suffer with condensation though? It'll be storing power tools and the mower.

"Hi Charles,

A metal shed is better than a wooden one if you want low maintenance and high security, but wood is better if you want a workshop or a traditional garden look.

Upkeep: Virtually maintenance-free; they will not rot, warp, or get eaten by insects.

Weather: Highly resistant to rain and wind when anchored properly, though cheap metal can suffer from internal condensation during damp UK winters.

Security: Generally harder to break into than standard thin timber walls.

Drawbacks: Can get very cold in winter and hot in summer, and it is harder to hang shelves or modify the interior.

If I can be of any further assistance please do reach out."

"Metal sheds tend to suffer with alot of damp as the walls aren't insulated. I would recommend either a plastic or composite shed they last for 10+ years"

"For storing power tools and a mower, I would choose a metal shed if low maintenance is the priority. Metal won’t rot like timber and generally requires less upkeep. Condensation can be an issue, though, so good ventilation and a suitable shed base are important. A wooden shed is easier to insulate and usually looks more attractive, but it needs regular treatment to prevent rot."

"I've always found metal sheds to be far more flimsy. They are also a lot harder to repair should any issues arise"

"Metal sheds are not better than wooding sheds because they can not withstand high winds and are a nightmare to put up"

"It really depends on what you need it for. Metal sheds are generally more durable, low-maintenance and resistant to rot, insects and fire, whereas wooden sheds tend to look nicer, are easier to customise and can offer better insulation. For something practical that will last with minimal upkeep, I’d go for metal. If appearance and a more traditional garden look are important, I’d choose wood. Both can be good options when properly installed and maintained."

"Metal sheds are low-maintenance and won’t rot, but condensation can be an issue. Good ventilation and an anti-condensation lining should help. For power tools and a mower, I’d say a decent metal shed is a good option"

"Short answer: yes, metal sheds can suffer with condensation.
My advice is to replace the shed with a traditional wooden one.
Paint with a good quality wood stain before building and then ensure annual maintainace coats.
Looked after a wooden shed can last many many years"

"depends on what you plan to use it for:
​Choose a Metal Shed if: Your main priority is low maintenance (no rotting, painting, or treating), high security for tools/bikes, and durability against pests and fire. Downside: They can suffer from condensation inside and get very hot in summer/cold in winter.
​Choose a Wooden Shed if: You want a traditional, attractive look that blends into the garden, better temperature regulation, or a comfortable space to use as a workshop. Downside: They require regular treatment and upkeep to prevent rot."
