ну почему же бред? Id должны быть разные только

<script>
function ch(x){
           x.parentElement.style.color = "red";	 
}
</script>
<div class="radio-check">
		<div class="check-wrap">
			<label class="check-field active" value="1">
				<span class="icon"></span>
				<em>Текст1</em>
				<input type="radio" onchange="ch(this)" name="ceiling" id="ceiling-gipsokarton" value="1" checked>
			</label>
			<label class="check-field" value="2">
				<span class="icon"></span>
				<em>Текст2</em>
				<input type="radio" onchange="ch(this)" name="ceiling" id="ceiling-gipsokarton" value="2">
			</label>
			<label class="check-field"  value="3">
              <span class="icon"></span>
				<em>Текст3</em>
				<input type="radio" onchange="ch(this)" name="ceiling" id="ceiling-gipsokarton" value="3">
			</label>
		</div>
