Emergency repair procedures should be as simple as possible, so that they may be performed safely by building maintenance personnel or other non-roofing professionals. These repairs should be considered temporary; roofing manufacturers and contractors should be contacted as soon as weather permits so that the appropriate permanent repairs can be made. A note of caution: It generally is not advisable to attempt roof repairs until severe weather has ceased because of the danger of high winds and the possibility of lightning strikes. Caution should be exercised when inspecting the roof after severe weather or when there is suspected damage to the roof assembly; storms may have left the roof in an extremely hazardous condition.
