Valley weather on Hartford's rooftops
The city sits in the river valley and gets weather from every direction: cold air down the valley from the north, wet systems up from the Sound, and wind that funnels between buildings. Flat roofs hold snow and ponding water and feel every freeze and thaw at their seams. Steep slate roofs in the West End shed snow but drop it in piles on porch roofs below. Street trees shade the older neighborhoods and fill gutters and drains, and summer heat on dark flat roofs ages membranes faster than in the suburbs.
