Roofing in Vermont is a roof that holds snow until the structure or the eaves complain. Slate on village houses fails at the nails, the hips, and the flashing while the field still looks eternal from the green. Metal sheds the load onto walks, decks, and lower roofs, which is a design fact you should mention. Asphalt ices where heat leaks into the attic. A farmhouse ell with a lower pitch dams the slide from the main roof. Name the material and the slope.
Chimney flashing and the warm eave are the paths into the plaster. A missing cricket holds a pack on the uphill side all winter and melts it inward during a thaw. Valleys fill with needles and then ice. If you can see the attic, say whether the boards are wet or the ceiling only stains when the weather breaks. A sagging line is a reason to stay off the roof entirely. Tell the caller about the sag from the ground.
A second layer hides soft boards until someone steps through in March. Underlayment at the eaves matters because meltwater refreezes there for weeks, not for an afternoon. Skylights and stove pipes are extra holes through a roof that stays wet underneath the pack. Note boots that have split. Access on a steep drive after a storm may be the constraint that decides when the work can happen. Say if a plow can reach the house.
Slate repair and asphalt replacement are different crafts. Do not describe them as one patch. Snow guards and where the slide lands matter on metal, especially over an entry. Moss on a north slope in a shaded hollow is damp, not charm. Antennas and old mounts are holes. A connected barn roof can leak into the house at the joint even when the main field is sound.
Give the town, slate or metal or asphalt, and whether water is active or only a thaw stain. Mention a sag, an ell, or a valley that ices every year. Stay on the ground. Call the number on this page.
