Roof Replacement in Atlantic County, NJ

Tear-off, and why it matters more here than the brochure suggests

Layering new shingles over old is faster and cheaper on the day. It also hides the decking, adds weight, and gives the new shingles an uneven surface to sit on, which shortens their life and makes wind damage more likely at the edges. Tearing off to the deck is the option we recommend, and on a coastal-exposure roof it is the one that lets the fastening pattern actually do its job.

What we find when the deck is open

Sheathing that has been quietly wet is the single most common surprise. It shows up under valleys, around penetrations, at the eaves where ice and standing water sit, and beneath a chimney that has been flashed with sealant. Soft or delaminated boards do not hold a fastener, and a nail that does not hold is a shingle that lifts. Replacing the affected sheathing is not an upsell; it is the condition under which the rest of the work means anything.

• Delaminated or spongy plywood and OSB
• Rot at the eave line and around penetrations
• Boards that have cupped or separated on older plank decking
• Framing damage from a long-running leak

The water layer under the shingles

Shingles are the first line, not the only one. Beneath them a replacement should carry a self-adhering ice and water membrane at the eaves and in the valleys, where water concentrates and where ice can back up, and a synthetic underlayment across the remaining field. A drip edge is fitted at the eaves and rakes so run-off is carried into the gutter rather than behind it and down the fascia.

Flashing gets formed, not sealed

Sealant is a maintenance material with a service life measured in a handful of years. Flashing is a permanent detail made of metal, shaped so that gravity does the work. At a wall we use step flashing woven into the courses with counter flashing over it; at a chimney the same, with the counter flashing let into the masonry. Where old flashing was simply smeared with roof cement, it is replaced rather than re-smeared.

Ventilation, so the new roof can dry

A roof assembly needs air moving from the soffits, up under the deck, and out at the ridge. Without it, moisture from inside the house condenses on the underside of the sheathing in winter and heat cooks the shingles from below in summer. A replacement is when an unbalanced system gets corrected — intake blocked by insulation, ridge vent installed over an unslotted deck, or a mix of vent types that short-circuit one another.

Fastening for wind

Manufacturers publish nailing patterns for standard and for high-wind installation, and the difference is real: placement in the nail zone, the number of fasteners per shingle, and whether starter strip is used at the eaves and rakes. On exposed sites — the Absecon Island municipalities, Brigantine, and open bayfront streets in Somers Point or Absecon — the high-wind pattern is the sensible default rather than an option.

The site at the end of the day

A tear-off produces a lot of debris and a lot of nails. Protecting landscaping and siding during the strip, keeping debris contained, and running a magnet over the drive and lawn afterwards is ordinary competence, and it is a fair thing to ask any contractor about before you sign.
