Shoreline homes, like this project in Groton, are often subjected to high coastal winds. IKO shingles deliver 130-mph wind resistance. If we install your roof, you can rest easy knowing that you are well protected.

Job Stories From Groton, CT
Groton Roofers to Resolve Leak in Kitchen

The owners of this ranch in Groton had a major leak that was right above the kitchen cabinets. So every time they had a heavy rain, the dishes would get a surprise washing. When they got a door hanger from us promoting our winter roofing, they immediately got a quote from us and scheduled the work for later that month. Suddenly a major rainstorm was on its way and the owners were worried that if they did not get the roof fixed soon they would have a mess on their hands. So they called and, because it was an emergency job, we were able to move up the work and got it done before the storm came. Our crew came and tore off the old shingles and replaced the rotten sheets of plywood. They then installed nine feet of Ice and Water barrier and installed Synthetic Underlayment. The shingles were Owens Corning Duration Quarry Grey. The entire installation, start to finish, was done in one day and the crew cleaned up the yard thoroughly. When the rainstorm finally came and poured down on their home, the owners opened up their cabinets to check on the leak and it was all dry.

Replacing and Recycling a Roof in Groton, CT

Here was a Cape in Groton, CT that had reached the absolute maximum lifespan of its roof. Shingles were curling and actually missing in several places. We gave this home a full roofing system, in Onyx Black shingles with a matching Owens Corning VentSure Ridge Vent. This vent comes with a Weather Protector moisture barrier that provides consistent attic ventilation. The old roofing asphalt was recycled, and will be used for CT and MA road paving.  Call or contact us today for a free price estimate on your roof replacement project.

Roof Repair & Replacement in Groton, CT

This was a raised ranch with attached garage in Groton, CT. It was completed with two layers of True Def Duration Quarry Gray shingles, with SureNail strip technology. The trademark SureNail strip features “a unique triple layer of reinforcement that occurs when the fabric overlays the common bond of the shingle laminate.” These strips also require less nails, which mean less trauma for your decking. Three rows of 9' Ice & Water shield were installed to all of the eaves in addition. We also removed and reinstalled a lightning rod system.

We have been noticing water stains on our upstairs bathroom ceiling. My husband went into the attic and discovered wet insulation, which we pulled out. It appeared to be coming from the gutters, so they were cleaned out. However, this morning, after last night's rain we are seeing more spots on the ceiling of the bathroom. So, there appears to be something else going on and we need a professional to take a look.
