Merrick is unincorporated Town of Hempstead and splits sharply. South Merrick runs to the canals and Merrick Bay and was hit hard by Sandy. North Merrick, above Sunrise Highway, is ordinary inland Nassau suburbia. The roof conversation is not the same in the two halves.
Elevation raises the roof into more wind, not less
South Merrick has one of the highest concentrations of post-Sandy elevated homes on Long Island. Elevating solves the water problem and creates a wind one: the roof sits higher in the wind profile, and the surrounding grade and neighboring structures that used to break the flow at ground level no longer do.
- Higher fastener count than a standard residential nailing pattern
- Upgraded starter course and a ridge system rated for the exposure
- Particular attention to eave and rake details, where uplift concentrates
- Corrosion-resistant hardware, because the house is closer to nothing but air and salt
- Ventilation re-checked, since elevation frequently changed the attic configuration
A standard suburban spec on a house standing twelve feet in the air two blocks off the water is under-built, and it is the most common thing we find when we are called in after somebody else's roof failed.
Substantial improvement thresholds
Properties in mapped flood zones carry a threshold most homeowners have never heard of: if the cost of repair or improvement crosses a defined percentage of the structure's value, the entire structure can be required to meet current flood code.
A roof alone rarely triggers it. A roof combined with siding, windows and interior work after a storm very much can, and crossing it turns a repair into a project with elevation requirements attached. If you are scoping several trades at once, sequence matters, and it is worth understanding before the work is planned rather than after.
Two policies, two deductibles
Wind is homeowners. Rising water is flood, and only if you carry a separate flood policy. After a serious coastal storm both are usually present, which means two claims, two adjusters and two deductibles on one event. Many policies here also carry a percentage-based hurricane deductible rather than a flat one.
North Merrick is a straightforward roof
Above Sunrise Highway there is no flood zone, no elevation, and no special wind exposure. Postwar and 1960s stock, simple gable and hip geometry, standard residential spec. Those jobs are faster and cost meaningfully less, and we quote them that way rather than applying coastal pricing to an inland address.
Frequently Asked Questions
Does my elevated house need a different roof specification?
Yes. Elevation puts the roof higher into the wind profile and removes the ground-level shielding that used to break the flow. We increase fastener count, upgrade the starter course and ridge, and pay closer attention to eave and rake details where uplift concentrates. A standard suburban nailing pattern is under-built on an elevated coastal house.
Could a roof replacement trigger flood code requirements?
A roof by itself rarely does. In a mapped flood zone, if the total cost of repair or improvement crosses a defined percentage of the structure's value, the whole structure can be required to meet current flood code — including elevation. Roof plus siding plus windows plus interior work after a storm can cross it, so sequence matters.
How long does a roof replacement take?
One to two days for a typical Long Island house. Tear-off and dry-in happen the same day — we never leave a roof open overnight.
Do you work in Nassau County?
Yes. We are based in East Patchogue and work across both Nassau and Suffolk. On Nassau jobs we confirm village versus town jurisdiction from the parcel before quoting, because Nassau has a far higher density of incorporated villages than Suffolk does.
