Nazar came to look at the concerns I had about my roof. He listened thoughtfully, evaluated the issues explained everything and promptly restored the ridge to my liking. He is the 'master' of these roofs!

Providence County holds Rhode Island's oldest housing stock — East Side Victorians, Federal-era homes, mill-village cottages and three-deckers — and most of it is wearing an asphalt roof that will need doing again. Interlock is aluminum, installed once, and covered by a lifetime warranty that transfers with the house.

The East Side, Armory and Blackstone districts were built for slate, and the streetscape still reads that way from the sidewalk. Interlock's aluminum slate profile holds that line at 0.41 psf installed, against roughly 8 to 10 psf for natural slate — an older frame is never asked to carry more than it was built for.
Every freeze-thaw cycle works meltwater into asphalt laps until they lift, and a Providence winter delivers a long run of them. Interlock's panels lock on all four sides, so there is no exposed lap across the field of the roof for meltwater to get under. (Ice dam formation itself is an attic insulation and ventilation issue, which we check at every estimate.)
Pawtucket, Central Falls and Woonsocket housing has been re-roofed in asphalt again and again, each layer another bill that comes back. Aluminum does not rust, and the Guardian Warranty from Interlock Roofing Ltd. is for life.
It is transferable, so the roof becomes an asset at closing instead of an inspection line to negotiate over.

I had a leak in my bathroom. The man that came was very nice and professional. Very informative thanks

Sloppy clean up. Numerous materials left in yard and driveway including an empty tube of sealant, an empty soda can, pieces of roofing materials, and nails and screws left in drive way. I just hope I have found all of them.

Friendly efficient great service

Great roof, insurance loves it because it’s fireproof. Looks like brand new after 10 years.

We are pretty happy, and we should be okay as long as there aren't any issues down the road.
