The zestimate is a reflection of more general pricing trends in your local market. Some margin for error comes with that. The size of that margin will vary with the amount of local sales activity. In my home market (Los Angeles) Zillow's median margin of error is 6.2%. In some metro area markets that error rate is in double digits.
You can find the margin of error in your local market here:

But, with the nature of improvements you've made, that still may not provide you with much peace of mind. Your best bet would probably be to hire a local appraiser in your area to give you his specific valuation of your home.

Why does the value of my house keep going down?
The house was valued at $145,500 when I bought it in 2009. I put a new roof, siding, garage door, entry door, and windows. The square feet were listed wrong also. Why ddoes your zestimate keep going down? It should be at least $165,000, not $140,000.
