The presence of icicles hanging off the eaves of a wood-framed structure is most likely due to: heavy snow followed by a thaw. improper insulation in wall cavities. use of a poor-quality roof sheathing material. lack of proper roof ventilation. failure to install a radiant barrier above the roof insulation.

Respuesta :

Answer:

Lack of proper roof ventilation

Explanation:

The icicles hanging off the eaves of a roof are due to lack of proper roof ventilation. This means after snowfalls the attic of the roof receives warm air which melts the snow above. This is caused because the upper part of roof is above 32⁰C (which melts the snow) and lower part of your roof is at a lower temperature which refreezes the snow dripping down to form icicles.
