Why don't more stadiums have roofs in the UK? Here's why... So to conclude, what are the main reasons why more stadiums in the UK don’t have roofs? 1. Cost – covering large capacity stadia with retractable roofs is a major project 2. The fact that pitches need to be exposed to rain, wind and sunshine to maintain that finely manicured state 3. Use – the practicalities of using the roofs can be prohibitive to play and rules where all concerned parties need to agree can be complicated 4. Cost effective – if the stadium isn’t multiuse with a diary full of profitable events, a costly retractable roof is hard to justify 5. Atmosphere – this one is totally subjective. Does playing under a roof increase or reduce the atmosphere of a match?
