Had to have my roof replaced due to defective workmanship of another company 9 years ago. Tom not only did an awesome job fixing what the other contractor should have done originally but did it in a quick time frame. His pricing was fair and reasonable. It’s nice to know there are still companies out there that are honest and do quality work. I would highly recommend Jannace Roofing for anything related to roof repair and installation. You won’t regret your decision!

As an attorney , I am held to the highest professional and ethical standards. As a roofer, Tom Jannace meets my profession’s standards. He is competent, trustworthy and equally important, he does what he promises. Weather permitting, he was always on time, always found the source of my roof problems and always left my business and residential premises neat and clean. His prices are reasonable and fair. Tom gets my highest rating.Ron Sickmen

Tom Jannace and his son Nick were very honest, dependable and reliable for my roof installation. They fully explained what was going to be needed and how long the job would take, and were reasonably priced. They were able to provide the service in a fast, timely matter compared with other local companies. I am very happy with my new roof and gutters and downspouts. I would definitely recommend this company to anyone needing a roof or roof repair. The roof workers were very careful to clean up and take care of any surrounding areas. Tom came by several times to make sure that the job was to his satisfaction and that everything was cleaned up after the job. His company came highly recommended with great reviews and I can see why. I have no complaints only compliments on a job well done.

My roof was damaged due to a storm and I needed an emergency repair done. Tom answered my call on a Saturday afternoon and shortly thereafter was at my house. He was prompt, polite and above all, professional. In addition, his price was more than reasonable. I highly recommend Tom and his team for all of your roofing needs. Thank you, Tom!

Long Island is a densely populated island in southeastern New York State, constituting a significant share of the New York metropolitan area in terms of both population and land area. With over eight million inhabitants as of 2020, it is the most populous island in the United States and the 18th-most populous island in the world. Just 0.35 miles (563 meters) from Manhattan at its western end, the island begins at New York Harbor and extends 118 miles (190 km) eastward to the North Atlantic Ocean with a maximum north-south width of 23 miles (37 km). Long Island’s land area of 1,401 square miles (3,630 km2) makes it the largest island in the contiguous United States, 11th-largest in the nation, and 149th-largest in the world.

Long Island is divided among four counties, with Kings (Brooklyn), Queens, and Nassau occupying its western third, and Suffolk its eastern two-thirds. As of 2020, more than half (58.4%) of New York City residents live geographically on Long Island in the boroughs of Brooklyn and in Queens, although in common parlance, the term “Long Island”, locally “the Island”, refers exclusively to the counties of Nassau and Suffolk. Conversely, locally, the term “the City” refers to Manhattan alone. The Nassau-Suffolk-only definition of Long Island is recognized as a region by the State of New York. Although geographically an island, the Supreme Court of the United States has held that given the island’s extensive ties to the mainland, it should be treated as a peninsula, giving the state jurisdiction over its maritime boundaries.

Long Island may refer both to the main island and the surrounding outer barrier islands. To its west, Long Island is separated from Manhattan and the Bronx by the East River tidal estuary. North of the island is Long Island Sound, across which lie Westchester County, New York, and the state of Connecticut. Across the Block Island Sound to the northeast is the state of Rhode Island. Block Island—which is part of Rhode Island—and numerous smaller islands extend further into the Atlantic. To the extreme southwest, Long Island, at Brooklyn, is separated from Staten Island and the state of New Jersey by Upper New York Bay, the Narrows, and Lower New York Bay.

Roofers can replace, repair, and install the roofs of residential and commercial buildings.

Roofing can be a physically demanding profession. It requires the stamina to stand, climb, and carefully walk in hot, cold, and sometimes windy, snowy, or rainy weather. The work that roofers do ensures that buildings are structurally sound and safe for the personnel or assets protected by the roof.

Some of the most common roof leak causes include an aging roof, broken or missing shingles, clogged gutters, and chimney damage.

Leaks, Shingle or Tile replacements, poor ventilation, and gutter maintenance are some of the many common problems that occur with roofs over time.
