I'll have to find where I read this, but I was just trying to cover all the bases on smoke/fire/co2 detection, and heat detectors for the attic and garage had been mentioned so I was looking to cover those aspects.HighTest said:Just curious, what are the sensors for? Is there concern that your asphalt shingles are going to melt? Fire concern?
Attic fire detectors are very important because attics have a lot of exposed dry wood that will cause any fire to escalate quickly. Also attic areas are common to large areas of a house so a fire spreads much more quickly to engulf the entire building than would be the case of a fire down in one of the segmented living spaces. Protecting asphault shingles is not the issue (although much of the roofing in my area is wood shingle, even brand new ones).HighTest said:Just curious, what are the sensors for?

Or is this for controlling a vent fan that would turn on in high temps?
If you have high temps on average, you may wish to read this article:
While insulation is our friend, if your attic isn't properly vented it'll radiate heat back into the living space through the night from that hot attic. Many compensate by turning up their AC system and spend more $ when a properly vented attic may save them $ by reduced AC costs in the summer. When done properly it doesn't necessarily make you colder in the winter either.
