New Britain winters, freeze-thaw and the roofs that take it
New Britain gets the full inland Connecticut winter. Snow stacks on the flat and hipped roofs of the multi-family blocks, and the repeated freeze and thaw of a central Connecticut February works water into every open seam and nail hole. Ice forms at the eaves of older houses where the attic is warm and the insulation thin, and the water that backs up behind it finds the first course of shingles. The city is hilly, so houses on the higher streets around Walnut Hill take more wind than those in the flats. Trees are fewer than in the suburbs, so moss is less of a factor than deferred maintenance and age.
