For replacement here we favor architectural shingles rated for high wind, with six-nail fastening, a wide ice-and-water barrier along the eaves and in every valley, synthetic underlayment, and a continuous ridge vent paired with clear soffit intake. On larger 1990s colonials with complex rooflines, that ventilation plan is what keeps a new roof from icing up in the first winter.
When replacement is the right call in Randolph
Replacement is the right move when repairs are becoming frequent, when shingles are failing in multiple areas rather than one, when the roof has two layers, or when the deck is showing damage from below. For a typical Randolph colonial the project takes one to three days depending on size and how much decking needs attention.
We tear off to the deck, replace damaged sheathing, install ice-and-water protection generously because of the local climate, lay synthetic underlayment, install new flashing at every wall and chimney, and finish with architectural shingles and ridge ventilation. Skylights that are more than a few years old are usually best replaced at the same time rather than reflashed.
