Along this stretch of coast, salt decides how long a roof lasts — not the weather report, not the warranty on the shingle. Interlock takes that decision away: aluminum throughout, so it does not rust, backed by the transferable Guardian Lifetime Limited Material Warranty from Interlock Roofing. Installed once, and that is the end of it.

From Groton and Mystic out to Stonington Borough, salt-laden air works on a roof year-round, and it takes steel fasteners first — which is how a panel roof loosens from the deck long before the surface looks tired. Interlock is aluminum throughout and does not rust, and that single fact is what keeps it working on open shoreline exposure.
Weathered shake is the look this shoreline was built around, and real cedar splits, cups and grows moss under constant salt and damp. Interlock's cedar-shake profile holds that appearance permanently, with none of the upkeep.
If the house sits empty between seasons, the value is not having anything to come back and find — no storm damage to discover in spring, no trades to arrange from a distance, and no replacement to schedule around a rental calendar.

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.
