Obviously, there are times when the need for new siding makes itself blatantly clear– for instance, when your siding looks dated and you are looking to improve curb appeal for resale value. However, if that’s not the case with your home, you may have to get a closer inspection in order to make the call. Extensive mildew, warping, rotting, cracks, and holes are all signs that it’s time to replace. You can also perform a quick test to check the siding’s brittleness. Take an edge and gingerly pull it away from your home. If it comes away easily, cracks, or warps, it is time to replace. Other signs of damage include bubbles in the siding exterior and the need to repaint frequently.
