I'm considering painting my dark grey asphalt-shingle roof white to help cool my house. Would this actually save energy? Also, I'm looking for a way to do it that doesn't end up looking terrible. I don't think pure white is necessary; just something closer to white than the dark grey. By the way, my dad owns a painting company, so I might be able to mix some leftover paint to do the job. What are your thoughts?

For sure, you can save energy with a lighter-colored roof! Your dad likely knows about roof coatings that are suitable for your local climate, so definitely check with him first. Plus, you can find options that are reflective but still mimic a traditional roof look instead of a painted one.
Yes, painting your roof white can help reflect heat and lower your cooling costs! However, keep in mind that just using regular spray paint isn't the best route. There are special roof coatings designed for this purpose that will last longer and look better. Regular paint might bubble up and create a mess in a short time, so it's best to explore those options instead.
Definitely ask some pros about it, especially your dad! He might have some valuable insights on the right materials to use.
Also, don’t forget that there are shingles designed specifically for heat reflection that might look way better than a painted roof.
Yeah, the Owens Corning website has some great examples of shingles that look decent while doing the job of heat reflection. Might be worth a look!
