Asphalt Shingle Replacement in Toms River, NJ

Asphalt shingle replacement starts with the wind class

Asphalt shingles are classified by how they behave in a standardized wind test. The residential code requires them to be tested to ASTM D3161 or ASTM D7158 and to meet the classification appropriate to the ultimate design wind speed at the building. D3161 uses classes A, D and F; D7158 uses classes D, G and H. Higher letter, higher tested speed. What the classification describes is a shingle installed the way the test installs it — which is where most of the real-world difference comes from.

That is why the same shingle can be a good roof on one house and a poor one two streets away. The product carries a rating. The roof earns it, through the nailing pattern, the starter course and the edge detail. On the Ocean County shore, where a west wind off Barnegat Bay or an easterly over the peninsula arrives with nothing in front of it, the gap between rating and installation is the whole story.

Where the site value comes from

New Jersey used to publish design load values in departmental bulletins. Bulletin 19-1, issued in September 2019 and revised in September 2022, consolidated the ground snow, wind and seismic bulletins and replaced the tables with a pointer to a site-specific hazard lookup. The bulletin warns in plain language that supplying only a city and state or a ZIP code returns the value for the centroid of that area and could understate the value that should be used for the site of interest.

In a township like Toms River, which runs from inland North Dover out to Ortley Beach on the barrier, that caveat is not a technicality. A ZIP-level value averages across positions that are genuinely different, and the address on the peninsula is the one that loses by it.

Fastening is the part nobody sees

• Not less than four fasteners per strip shingle as a code floor, with the manufacturer's instructions governing above it
• Six-nail high-wind pattern where the rating depends on it — a condition of the class, not an extra
• Nails driven in the nailing zone, flush, not overdriven through the mat and not high above the line
• Starter course at the rakes as well as the eaves, with its adhesive strip toward the edge
• Ridge cap fastened to the manufacturer's high-wind schedule rather than face-nailed by eye
• Drip edge under the underlayment at the eave and over it at the rake

Every item on that list is invisible once the roof is finished, and every one of them is a reason a roof loses a run of shingles at fifteen years instead of at twenty-five. It is reasonable to ask a contractor, before work starts, which pattern they are installing to and which manufacturer instruction that pattern comes from.

What the coast does to the surface

Salt aerosol carries well inland on the same onshore wind that brings the rain, and because salt is hygroscopic it draws moisture out of the air and holds it against the shingle. The surface stays damp for longer between rains than the same surface would inland, which is enough for Gloeocapsa magma to establish on slopes that do not get direct sun. That is the source of the dark vertical streaking on north-facing roofs from Beachwood through Point Pleasant.

The streaks themselves are cosmetic. What is not cosmetic is what happens underneath: the growth loosens granules, and granules are the shingle's protection from ultraviolet light. Once bare asphalt is exposed it ages quickly. Copper-bearing algae-resistant granules suppress the growth for years and are worth specifying on this coast, but they treat the symptom rather than the exposure.

Frequently Asked Questions

What wind classification does my roof need?

The one that matches the ultimate design wind speed at your address. The residential code requires asphalt shingles to be tested to ASTM D3161 or ASTM D7158 and to carry the classification corresponding to that speed. D3161 runs classes A, D and F; D7158 runs classes D, G and H. Which class applies is a function of the site value, not of the town, which is why the value gets looked up per address.

How do I find the design wind speed for my address?

New Jersey does not publish it in a table any more. Bulletin 19-1 from the Department of Community Affairs consolidated the old wind, snow and seismic bulletins and directs users to a site-specific hazard lookup instead. The bulletin is explicit that entering only a city, state or ZIP code returns the value for the centroid of that area and could understate what the site itself requires — which on a barrier peninsula is exactly the situation.

Four nails or six?

The code minimum is not less than four fasteners per strip shingle, and the manufacturer's approved instructions govern above that. Nearly every manufacturer requires six nails in the high-wind pattern, and that pattern is a condition of the higher wind rating rather than an upgrade. A shingle rated to a high class and fastened with four nails is not carrying the rating it was sold with, and the wind coverage in the warranty reflects that.

Architectural or three-tab?

Three-tab is lighter, thinner and single-layer, and it is largely gone from new work. Architectural — laminated — shingles carry two bonded layers, weigh more, and are what current wind classifications are generally built around. The choice matters less than the installation: an architectural shingle nailed above the nailing zone performs worse than a three-tab nailed correctly.

Do algae-resistant granules actually do anything?

They slow the streaking. The dark stains on a north slope are Gloeocapsa magma feeding on the limestone filler in the shingle, and copper-bearing granules leach slowly enough to suppress it for years. On the coast, where salt keeps the surface damp between rains, that suppression is more useful than it is inland. It is a cosmetic benefit rather than a structural one, and it does not extend the shingle's service life on its own.

How long should a shingle roof last on the shore?

Less than the figure printed on the wrapper. Constant wind working the seal, salt holding moisture on the surface and full sun on the water-facing slopes commonly bring an asphalt roof on the Ocean County coast to the end of useful service somewhere between the mid-teens and the low twenties, against warranty figures of thirty years and up. Installation quality and attic ventilation move that number more than the product grade does.
