Here was a ranch home in Stonington, CT which had a lot of moss and lichen build up on its shingles. Both moss and lichen spores love to take hold and grow on the north side of trees, as well as the shady areas of roofs. Older, 3-tab shingles, like the ones used on this home, were not designed with any type of resistance to this type of fungal growth. Power washing and chemical solvents are not recommended as they will often actually take granules of asphalt off, and can even void some insurance plans! The amount of shade on this roof is still going to be conducive to moss growth, however the Owens Corning Duration shingles we install are manufactured to ward off algae.

Job Stories From Stonington, CT
Insurance Problems in Stonington, CT

Our sales rep met this homeowner last year when he talked to him a bit and gave him his card. He just recently called for an estimate! The homeowner had a cute and humble ranch surrounded by mansions. Their insurance was going to drop them because they thought their roof was old, but it wasn’t too old and there wasn’t very much wrong with it. Our rep did find mold in the attic and suggested putting a claim in instead.

A 50 Year Warranty Roof Replacement in Stonington, CT

For this job in Stonington, CT we tore off and provided disposal of two layers of old roofing material. The new shingles we installed are Harbor Blue Owens Corning TrueDefinition Duration shingles with a SureNail strip. These shingles carry a 50-year Lifetime Warranty, which really goes above and beyond other warranties in the industry. We also flashed a metal chimney, and provided an extensive clean up of the job, with only a premium roof and warranty in our wake.

I am helping my 88 year old mother. She needs roof repair but not an entire roof. There is water getting in by this chimney, and I could see a sliver of light in the attic (missing flashing?) I also see an issue with the corner of the roof. And we saw squirrel droppings in attic. Thank you for coming to take a look and giving us an estimate.
