How much does a new roof, boiler or set of windows actually add to my Sandy Springs home's value?

A new roof, an updated HVAC system or new windows can support a higher price in Sandy Springs, but none of them adds a fixed dollar amount, since buyers and appraisers weigh the improvement against the age and condition of everything else in the house. These upgrades tend to matter most when they remove a buyer's inspection concern, like an aging roof near the end of its life, rather than functioning as a standalone selling point. The real number comes from comparable Sandy Springs sales where similar updates were already made.
