Roofing crew installing shingles on a house in Deer Park, New York

Alec's Construction repairs and replaces roofs in Deer Park (11729) — leaks traced to the cause, flashings and valleys, wind and ice-dam damage, and full tear-off replacements — working out of the yard in East Patchogue. Repairs and sheet-metal work run straight through the winter; replacements go on with the warm days.

Roofs in Deer Park

Deer Park is the north end of the Town of Babylon, inland on flat sandy ground with no tidal water, so a roof here faces wind and trees and nothing else. The housing is mostly 1950s and 60s ranches, capes and splits on small lots, with street trees from the same era standing over them, and the older houses along Deer Park Avenue and Carlls Path sit under bigger oaks. On a flat, open hamlet a strong gust has room to build, and what it usually takes is one slope — the windward side of a ranch, a few rows of shingles at the rake, a strip along the ridge. The industrial and commercial strips along Commack Road and Grand Boulevard have big flat roofs with rooftop units that take the same wind across an open surface. In Deer Park the common roof call is partial damage on a roof that is otherwise fine.

What We Look at First in Deer Park

After a wind event in Deer Park we photograph the whole roof, not just the missing shingles, because the creased and unsealed tabs around the gap are part of the damage even if they are still there. We lift tabs on the windward slope to see how far the seal failed. Then we decide whether it is a repair, a slope or the whole roof, and we write it that way for the carrier. Permits go through the Town of Babylon in Lindenhurst.

Pines, Oaks and Roofs on Sandy Ground

In Deer Park the roof's biggest threat sits next to it. Pitch pine and oak stand over ranches and capes on sandy ground, and after a wet week a strong gust can bring a whole tree or a heavy limb onto the roof. The rest of the time the trees work slowly: needles and leaves pack the valleys and hold water against the shingles, limbs scrub the granules off the surface, and shade keeps moss and damp on the north slope.

So a roof inspection here looks up as well as down. Overhanging limbs get flagged, valleys get cleared and checked for wear, and the shaded slopes get a closer look for soft decking. A valley that has been holding wet needles for years is often where the leak is.

The houses are mostly simple gable roofs — ranches, capes, hi-ranches — which makes a full replacement straightforward when it is due: tear-off to the deck, sheathing repaired, ice-and-water at the eaves and valleys, new flashings, and ventilation balanced so the attic stays dry.

Failed step flashing and old roof cement where a chimney meets the shingles

Leaks Are Flashing Problems Until Proven Otherwise

The open field of a roof almost never leaks. Water gets in where the roof meets something else — a chimney, a wall, a dormer, a valley, a vent pipe, a skylight — and on a great many Long Island roofs that flashing was done once, failed, and has been covered in roof cement ever since. Roof cement goes brittle within a few winters and hides the failure while the water keeps getting in.

So a repair starts by finding where the water actually enters, which is often several feet from where the stain shows, and fixing the flashing there. Repairs, flashing and sheet-metal work run all winter. Full asphalt replacements go on the warmer days, and shingles laid in the cold are hand-sealed so they hold in the first wind.

Permits in Deer Park

Deer Park files with the Town of Babylon at Town Hall in Lindenhurst. Roof replacement is permitted work in most of Suffolk, and the limit on shingle layers decides whether the old roof has to come off — on our jobs it comes off regardless. We file the permit.

Frequently Asked Questions

Wind took shingles off one slope of my Deer Park ranch. Can you replace just that slope?

Often, yes. If the rest of the roof is sound and the shingles can be reasonably matched, replacing one slope is a legitimate repair. What matters is how far the damage really goes: tabs that were lifted and creased but did not blow off have lost their seal and will go next time. We check them by hand and photograph them so the claim covers the real damage, not only the shingles in the yard.

Does a new roof fix ice dams on a Deer Park house?

Not by itself. Ice dams come from attic heat melting snow that refreezes at the cold eave. Ice-and-water membrane at the eaves limits the damage, but the cure is air sealing and ventilation in the attic so the roof deck stays cold. We look at the attic on every roof walkthrough.

Can a roof in Deer Park be replaced in winter?

Repairs, flashing and sheet-metal work run all winter. A full asphalt replacement is a warmer-day job, because the seal strip on the shingles needs warmth to bond; when a replacement has to go on in the cold, every course is hand-sealed so it holds in the first wind. We schedule around the forecast.

Who issues the permit for roofing work in Deer Park?

Deer Park files with the Town of Babylon at Town Hall in Lindenhurst. Roof replacement is permitted work in most of Suffolk, and the limit on shingle layers decides whether the old roof has to come off — on our jobs it comes off regardless. We file the permit.
