Usually, yes, but only once. Connecticut’s building code generally lets you add one layer of new asphalt shingles over one existing layer, never over two. Most roofers still recommend a full tear-off so they can repair the decking and add an ice and water shield, which matters a lot in a state where ice dams form every winter.

In most cases, yes. Connecticut towns like Thomaston generally require a building permit for a full roof replacement, and your contractor typically pulls it through the town’s building department. If a roofer suggests skipping the permit, take that as a red flag.

Most homes get a full asphalt shingle replacement in one to two days, weather permitting. Steep pitches, larger homes, multiple layers to tear off, or rotted decking can stretch it to three days or more. Metal, cedar, and tile roofs take longer because the installation itself is slower and more detailed.

The crew protects your landscaping, removes the old roof, and inspects the decking for rot or soft spots. Next, the ice and water shield goes along the eaves and valleys, followed by synthetic underlayment, flashing, drip edge, vents, and finally the shingles or metal panels. A good crew wraps up with a magnetic sweep for stray nails and a final walkthrough with you.

Standing seam metal tops the list, since snow slides right off and the panels shrug off freeze-thaw cycles for 50 years or more. Architectural asphalt shingles also handle Connecticut winters well when your roofer installs them with an ice and water shield and good attic ventilation. Cedar and tile can work too, though they need more care to stay leak-free through ice and heavy snow.
