Sunny weather cost an Elland man hundreds of pounds in repairs when intense sunlight triggered a fire in a bedroom at his home on Saturday evening.
Elland Fire Station crew commander Elliott Webster said the blaze broke out at 7.30pm at an address in Melrose Terrace.
He said: “A man looked up as he was gardening and saw smoke coming out of a bedroom. He went inside and put most of the fire out himself.
“There was a lot of damage around the windows.
“What appears to have happened is that the sun has been shining all day onto a concave vanity mirror on the windowsill which has had a magnifying effect and caused the blaze.
“I would warn householders to beware of this kind of thing happening as summer approaches.”
