I’m considering adding a roof vent to vent a currently non vented attic. I’ve taken provision for air intake and was considering a solar powered vent. However it turns out these run all the time when the sun is out, not just when the temp gets high. Bad idea or not? I suspect a bad idea in the winter. This attic is in a hundred year old rowhome and getting electricity to the attic may be quite a chore although probably ultimately doable. Powered vents are way cheaper than the solar. Thanks

The most common way to make your own parging mix is to use either Type S mortar for block or Type N for brick and add a concrete bonding additive.

A solar vent is ONLY cost effective in lieu of hiring an electrician to install a new power line. As for running year round... there is the Gable vent style, where the solar panel is seperate from the fan. You can then install a wall switch to interupt the power flow during the winter.

Powered vents (wired or solar) seldom last more than a few years. Passive vents (ridge, gable, or box vents) work great without power, don't cost anything to run, don't wear out, and are much less expensive to install. Investigate them before dropping money on powered vents.
