February is the long month in Haverhill. The sun swings low over the Merrimack, the melt runs off the roofs at noon and locks up again by four, and before you know it there is a foot of hard pack sitting exactly where nobody wants it. N R Gutters Inc handles the snow end of that — clearing drives and walkways, breaking loose the packed edges, taking weight off rooflines and eaves before the ice can set. Old Haverhill houses come with steep pitches, deep overhangs and porches that catch every slide, so the work happens as much overhead as underfoot. Getting to it early, while the snow is still snow, is the whole trick.
