Most home improvements ranging from replacement windows and doors to new siding or roofing will give you a return on investment ranging from 60% to 80%. Considering that you will also most likely save money on energy efficiency with many of these home improvements, you come out on top.
When you replace old windows with new energy efficient windows your return on investment is usually around 75%. You will also save up to 43% on your energy costs which puts that money in your pocket. You may also consider your return to be having a more beautiful house. Replacement windows and doors can also improve security and noise pollution in your home.
Siding is in the same range as far as ROI and with siding you can get additional energy efficiency and the knowledge that you won't have to repaint your house. Seamless steel siding is fire resistent which can give you extra peace of mind if you live in an area where brush fires could be an issue.
A new roof is almost always a good investment, especialy if your current roof has any structural weaknesses or damage. This can lead to water damage, wind damage, mold, and other costly home repairs. Part of the return on your new roof investment is knowing you won't have to worry about roof leaks and wind damage with today's roofing technology.
Patio covers and sunrooms add usable living space to your home which can greatly increase your homes value and style. These changes also give you an outdoor space you can enjoy year round.
Overall, with the benefits of home improvements and the peace of mind many of them bring, you will be happy you decided to make changes and enhance your home. Even if your not concerned with resale values these changes will help you to get more from your home.
