A Roofer Who Knows
Bohemia's Streets
Founded in 1855 by Czech immigrants and grown into a busy Islip hamlet of roughly 10,000 people, Bohemia mixes century-old landmarks with postwar subdivisions and newer construction. That range means no two roofs on the same block are quite alike, and a good estimate starts with knowing which is which.
J. Great Roofing has worked the South Shore since 1999, and Bohemia sits an easy drive from our West Babylon yard by way of Sunrise Highway and the Long Island Expressway. From the older homes near St. John's Church and Church Street to the condo communities off Smithtown Avenue, this is territory our crews cover week in and week out.
Because we know the town, an estimate here comes with real context. We can tell a 1960s ranch roof from a newer subdivision roof at a glance, flag the flashing details that tend to fail on Bohemia's older homes, and match a GAF shingle that suits the pitch and the exposure. That is the difference between a quick guess and a roof that lasts.
Inland Sun, Open Wind,
Winter Ice
Much of Bohemia went up during the postwar boom, so high ranches, splanches, and colonials fill the streets between Lakeland Avenue and Smithtown Avenue, with newer homes and condos added later. Set inland around Long Island MacArthur Airport, these roofs take a different beating than the town's South Shore neighbors sitting on the water.
Open airport land and flat terrain give wind a clear run at the roofline, summer sun bakes the shingles, and winter brings the ice dams common to older eaves. A roof built for Bohemia has to shrug off UV, hold its tabs down in a blow, and drain the eaves clean before ice can back up. After 25-plus years on Long Island, these are the failures we look for first when we walk a Bohemia roof.
- UV-worn shingles. Sun-baked asphalt roofs that have lost their protective granules and turned brittle.
- Wind-lifted tabs. Open exposure near the airport that peels back shingle edges and ridge caps.
- Failed flashing. Brittle chimney, skylight, and vent details that let water sneak past the shingles.
- Ice dams. Meltwater backing up under the eaves of older ranches through the coldest weeks of winter.
- Tree debris. Oaks and pines near Connetquot River State Park that clog valleys, gutters, and downspouts.
- Aging decking. Plank or early plywood that only reveals soft, water-stained spots once the old roof comes off.

Bohemia Roofing FAQs
Straight answers to what Bohemia homeowners ask us most.
Yes. We cover all of Bohemia (11716), from the older streets around Church Street and Locust Avenue to the newer subdivisions and condo communities like The Hedges, Park Place, and Fairfield Estates off Smithtown Avenue. Our home base is 619 Sunrise Hwy in West Babylon, and crews reach Bohemia quickly by way of Sunrise Highway and the Long Island Expressway.
Bohemia grew fastest after World War II, so the housing stock leans toward high ranches, splanches, and colonials, with newer construction mixed in. On those roofs we most often see sun-baked asphalt shingles that have lost their granules, cracked pipe and chimney flashing, ice-dam damage along the eaves, and older decking that only shows its condition once we tear the old roof off.
Bohemia sits inland around Long Island MacArthur Airport, so roofs here take open, unobstructed wind off the flat airport land plus strong summer UV and winter ice dams. Sun degrades shingles from above while wind lifts tabs and drives rain under loose flashing. We build Bohemia roofs with wind-rated GAF shingles, sealed underlayment, and upgraded flashing so they hold up year-round.
Yes. Bohemia has sizable light-industrial and commercial corridors along Lakeland Avenue, Church Street, and the airport business parks. We install and repair commercial and flat roofing systems alongside our residential work, so warehouses, offices, and shops in Bohemia can call the same GAF Master Elite crew that handles the town's homes.
We offer 24/7 emergency response for active leaks and storm damage in Bohemia. Because we run from West Babylon and cover the Town of Islip every week, a crew can reach Bohemia fast to tarp and stop the water. Most full roof replacements are completed in a single day. Call (631) 669-6269 any time.
