The Connecticut River valley runs a roof through the full cycle every winter — snow, thaw, refreeze, repeat — and asphalt seams open a little more each time. Interlock ends that cycle for good: one aluminum roof, installed once, carrying the lifetime, transferable Guardian Warranty from Interlock Roofing Ltd.

Valley winters cycle between thaw and hard refreeze more often than the shoreline ever does, and every cycle works water backward under asphalt laps. Interlock's panels lock on all four sides, so there is no exposed seam across the field of the roof for backed-up meltwater to get under. (Dam formation itself is an attic issue — insulation and ventilation, which we check at every estimate.)
West Hartford, Simsbury and Hartford's older streets are full of houses designed for slate, and slate is a structural commitment: roughly 8 to 10 psf on a frame that may be a century old. Interlock's aluminum slate profile lands at 0.41 psf installed and holds the same roofline without an engineer's report.
The Guardian Warranty is lifetime and transferable, so the roof stays an asset when the house changes hands rather than a line the buyer's inspector flags. Manufactured by Interlock Roofing Ltd. and installed by their exclusive certified New England installer.

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.
