Last fall I had an addition put on my prefab house. I now have an attic. I know I have enough insulation as the attic temperature stayed below freezing all winter. Now that I has hit 60 for a few days, I see the temp. at 130. I use a indoor/outdoor temperature sensor to do this. Has anyone ever checked their attic temp.? Anyone ever hear what is to hot and a vent fan is needed? I did an internet search and it was hard to tell if a roofer or vent fan person was advising you. lund

130...guessing you have dark shingles? Like mentioned, a ridge vent is the way to go if you have a vented soffit. Regular roof vents are kind of a pain to put in an already roofed house, though not impossible. Gable vents are another possible option.

Yeah, you need to make sure you have both adequate soffit ventilation and roof venting. There are three ways for the last part. Roof vents, which are least efficient. An attic fan, which works but drones on all night in the summer or ridge venting. The temps you mentioned are way too high for March.
Ridge venting is pretty easy to add to a roof.
Make sure if you do have ventilated soffit (which you need) that the insulation is not blocking the venting.
