Bay Shore is a Town of Islip hamlet with two distinct housing stocks. Near Main Street and down toward the water there are large, architecturally serious homes from the era when this was a summer destination. Inland it is postwar and later, on ordinary suburban lots. The siding conversation is different in each.
Salt decides the fastener, not the siding
Fiber cement and vinyl both handle salt air fine. Neither corrodes. What corrodes is every fastener holding them to the house, and on a property within a few blocks of the Great South Bay that is not a theoretical concern.
A corroding nail does two things: it bleeds a rust stain down the face of the siding, which is permanent-looking and impossible to clean off fiber cement, and it eventually loses its hold. Stainless fasteners on coastal exposures are the correct specification, not an upsell. Ask what any contractor is planning to use and get the answer in writing.
The older houses near the water
The larger period homes here have deep eaves, wide trim boards, bracket detail and multiple siding exposures on one elevation. Wrapping all of that in builder-grade vinyl flattens the house — the trim gets capped, the shadow lines disappear, and something that was worth looking at becomes generic.
Fiber cement holds those details because it can be milled and painted like wood. On a house with real architecture near Main Street it is usually the answer, and the resale argument alone tends to carry it.
Ferry-district exposure
Properties down by the Fire Island ferry terminals take direct onshore wind off the bay in every nor'easter. Wind-driven rain finds any gap in the flashing, and the gaps are always in the same places.
- Kick-out flashing where a roof edge dies into a wall — the number one hidden leak
- Window and door head flashing, frequently omitted entirely on older work
- The band joist and rim between floors on a two-story
- Where a deck ledger passes through the siding
- Penetrations for hose bibs, dryer vents and electrical
Siding replacement is the one moment every one of those is accessible. Done right, the flashing package is worth more than the siding product itself.
Inland Bay Shore
North of the highway it is a straightforward suburban re-side: postwar and 1960s stock, simple elevations, standard exposure. Vinyl performs perfectly well there and the price reflects it. Not every house needs fiber cement, and we will say so.
Frequently Asked Questions
Do I need stainless fasteners near the bay?
Within a few blocks of the water, yes. The siding itself does not corrode but the fasteners do, and a corroding nail bleeds a permanent-looking rust stain down the face — impossible to clean off fiber cement — before it eventually loses its hold. Get the fastener spec in writing from anyone quoting a coastal job.
Will vinyl ruin the look of an older Bay Shore house?
It can. The larger period homes near Main Street have deep eaves, wide trim and bracket detail, and wrapping all of that in vinyl caps the trim and flattens the shadow lines. Fiber cement can be milled and painted like wood, so it holds those details. On a plain postwar house inland, vinyl is perfectly appropriate.
How long does a siding job take?
Three to six days on a typical Long Island house, depending on size, how many stories, and how much trim and flashing work comes with it. Fiber cement runs longer than vinyl because the material is heavier and slower to cut and hang.
Do you have to remove the old siding?
We recommend it and we quote it that way. Siding over siding hides whatever is wrong with the sheathing underneath, adds thickness that throws off every window and door detail, and makes proper housewrap and flashing impossible. It is cheaper today and it is how water damage stays hidden for a decade.
