Knox County, ME
On the mid-coast, the roof itself is rarely the expensive part — getting a crew and materials to a peninsula or out to the islands is. Interlock is the roof that never books the return trip: aluminum throughout, no rust, no maintenance schedule, and a lifetime warranty that transfers with the house.

Getting a crew and materials out to Vinalhaven, North Haven or the end of the St. George peninsula is the real expense of any roof here, and it repeats every replacement cycle. Interlock is installed once and does not schedule another visit.
Rockland, Rockport, Camden and Owls Head live in salt spray and working-harbour air, which corrodes steel panels and — sooner — steel fasteners, so a roof loosens quietly from the deck before it ever looks worn. Interlock is aluminum throughout. It does not rust.
Exposed shoreline and hillside lots get the full force of a coastal storm, and asphalt hands it a lifted tab to start on. Four-way interlocking panels offer nothing to catch, and are warranted to resist wind speeds up to 120 mph (193 kph) when installed to manufacturer specification.
The Guardian Warranty from Interlock Roofing Ltd. is lifetime and transferable to whoever owns the place next.

Reviews
Our house experiences high wind and exposure to the elements on the Maine coast. Interlock offered competitive pricing on aluminum shingle roofing. The entire experience was good, from quotation, removal of the old roof, and installation of the new roof.

Interlock was great, and installation was just as told to us by sales. The crew worked hard, cleaned area each day and roof looks great! I was impressed by their professionalism and also had a call from home office checking during the install.

— Gary R., Orrs Island, ME
Our entire experience; inquiry, ordering, installation, and follow up has been excellent. The roof was justifiably costly and definitely worth the investment. The appearance of our house has been greatly enhanced.
