Middlesex County runs from the river bends at Haddam down to the Sound at Old Saybrook, and roofs here take damp, salt and wind in the same year. Interlock answers all three at once: aluminum throughout, locked on four sides, and backed by a lifetime limited warranty for the homeowner who installs it, transferable to whoever buys the house next.

Down near the river mouth the air carries salt, and inland the valley holds moisture long after the rain stops. Steel panels and steel fasteners corrode under both; Interlock is aluminum throughout and does not rust, which is why it keeps holding to the deck when coated products have already begun to streak.
Essex, Chester and Deep River are picture-book Connecticut, and the roofs that suit them are cedar shake and slate — both of which age badly here and both of which Interlock offers as a permanent profile instead of a maintenance schedule.
Storms tracking up the Sound unzip asphalt by catching one loose tab. There is no exposed lap seam to catch, and the system is warranted to resist wind speeds up to 120 mph (193 kph) when installed to manufacturer specification.

Had an impressive inspection and recommendation to improve the water intake to the gutters

Everybody was great to work with highly professional. Any underlying damage was all taken care of and we love the roof.

> We had the pleasure of meeting Jonathan Brown at the Mohegan Sun Home Show and couldn’t pass up the opportunity to tell him how happy we are with our Interlock roof of ~20 years. We constantly receive compliments from people passing by on how beautiful it looks. Most of all, we appreciate the peace of mind it gives us—knowing we’ll never have to replace our roof, thanks to the lifetime warranty and guaranteed protection against leaks.

Jonathan was great help getting us all the information needed for the roof and what to expect, and the whole process. The installation was fast, the roofers were hard working and professional. The look of the metal roof is superb!

It was a pleasure working with Interlock from beginning to end. The back office was good about setting expectations for job start and duration, delivery of materials (which happened on time) and work to be performed.
