The northwest hills get Connecticut's deepest snow and hardest freeze-thaw — the conditions that turn a roof into a recurring repair. Interlock ends that: an aluminum system that sheds snow, leaves ice-dam meltwater no seam to leak through, suits a period home in a historic town centre, and never needs replacing.

Elevation in the northwest hills means more snow, more melt-and-refreeze cycles, and more ice damming than anywhere else in Connecticut — and ice dams do their damage inside the house, in ceilings and walls. Interlock's panels lock on four sides with no exposed lap seam for backed-up meltwater to find, and the surface sheds snow before a heavy saturated load builds.
Litchfield, Washington, Sharon and Salisbury hold some of the best-preserved colonial town centres in New England, much of it originally slate or wood shake. Interlock's matching profiles keep that appearance permanently — real wood in this climate splits, cups and grows moss.
If the property is not year-round, the value is arriving in spring with nothing to discover — no winter damage, no contractor to arrange from the city, no replacement to schedule. One roof, lifetime warranty, transferable when you sell.

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.
