Roofing expert recommends professional assessment after heavy snow

Homeowners with large amounts of snow on their roof should consult a licensed contractor to see if the snow must be cleared immediately, said Buffalo Construction roofing expert Mike Klein. Anything over one foot should be removed, he added. Klein also discussed the signs of a potential roof collapse, including deformations, cracked wood, doors or windows that have become difficult to open, popping sounds, and new or enlarged wall and ceiling cracks.
