6. We might not be a good investment unless you love our work. Payback time is not always there. Your green roof will reduce your cooling costs and extend the life of your roof, but if you don't find it beautiful, it might not be the way you want to spend your money. As a general rule, the next person to buy your house will not pay you as much for the kitchen as you paid us to renovate it. So renovate because it makes your life more comfortable, convenient and beautiful, and because you love how remodeling can change a house for the better. If you look just at the raw numbers, you should insulate the attic, replace the water heater when it breaks and run those ugly kitchen cabinets into the ground.
