As a designer, it is important to consider not just the aesthetic appeal of a building, but also its practicality and longevity. With the environmental effects of climate change becoming increasingly apparent, it is essential to ensure that roofs are in good condition and able to withstand extreme weather conditions. For contractors, this means paying close attention to signs that indicate the need for roof replacement. Some of these signs include water stains on the ceiling or walls, missing or cracked shingles, excessive granule loss, sagging or dipping rooflines, and visible damage from hail or wind.
