Hi everyone hope someone can help me out . 
 
	We have very large pharapet gutters on the house here and suffer every winter with leaks as they block up and overflow the lead work . 
 
	We have a house alarm fitted with numberous PIR sensors etc . 
 
	My question is - would we be able to install a number of float switchs on the roof to trigger the main house alarm ? ? 
 
	 
 
	Hope this will make sense
 
	all help is very much appreciated 
 
	kind regards
