When considering solar, roofing has to be considered as well since a sound roof is a pre-requisite and the majority of the physical work and risk related to a solar installation are related to the roof. If the roof is not in an acceptable condition for solar installation, then this should be considered an ideal opportunity to replace the roof. Replacing the roof at the time of solar installation saves time and money and provides a clean finish. It also avoids the hassle and costs of removing and replacing the solar panels if the roof needs to be repaired or replaced after solar is installed.
