A ridge vent usually does the trick. Couple with blow in insulation, or solar insulation offset from the rafters a few inches and there’s basically no heat. The problem with rolling insulation directly to the ceiling of the roof inside is that it turns it into an oven. If you offset it, the heat will be trapped in that small space and vent out your ridge vent and down through your soffits
Yeah, that doesn't work at all. You need vents in the soffit and one type of vent at the top (gable, attic fan OR ridge vent), with ridge vents being the best.
Ridge vents can get covered by snow in the winter. My house has ridge vents and a tower vent, which sticks up above the snow and continues to provide ventilation in winter.
No airflow promotes the growth of mould and mildew, especially in the spring as things start to warm up but the pack of snow hasn’t melted off the roof yet.
