A Fairfield County home deserves a roof you install once. Interlock's aluminum systems hold slate and cedar-shake rooflines permanently — no splitting, no streaking, no replacement in fifteen years — and stand up to Long Island Sound salt and hurricane-season wind. The lifetime warranty transfers with the house, so it becomes part of its value rather than a deferred cost.

In Greenwich, Darien, New Canaan and Westport, a roof is a visible part of what the property is worth — and a buyer's inspector pricing a near-due asphalt replacement takes that straight off the offer. A lifetime aluminum roof with a transferable warranty does the opposite: it is one fewer thing anyone can discount you on.
Much of the county's best housing stock was built for slate or wood shake, and true slate replacement is heavy enough to need structural reinforcement. Interlock's slate and cedar-shake profiles hold the roofline exactly, at a fraction of the weight, and several towns' review boards recognise the traditional appearance.
From Greenwich through Norwalk and Bridgeport, salt air corrodes steel panels and — first — steel fasteners, quietly loosening a roof from the deck. Interlock is aluminum. It does not rust.
Coastal Fairfield has taken direct hurricane damage in living memory. Four-way interlocking panels give wind nothing to lift.

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.
