A documented roof replacement project in Raleigh, NC, start to finish.
Roof Replacement in Raleigh, NC
A 2004 Brier Creek two-story carried two shingle layers and a soft north-deck section when the owners called after a spring wind event. We tore off to the sheathing, replaced 14 sheets of OSB, and installed a full GAF Timberline HDZ system in Charcoal with the ridge ventilation corrected to the 2018 North Carolina code. Permitted through City of Raleigh Development Services and finished in a single day, curb to curb.

The Situation
A 2004 two-story on a cul-de-sac off Brier Creek Parkway, in the Toll Brothers master-planned community that grew up around the Arnold Palmer championship course at Brier Creek Country Club during the early-2000s build-out near RDU and the Research Triangle Park. The owners were the home's second family and had inherited a roof someone had already re-covered once, a fresh layer laid straight over the original instead of torn off. They called Summit & Oak not after a storm but because a crew cleaning their gutters mentioned the field felt spongy underfoot, and they wanted a straight answer before listing the house. The address sits inside Raleigh city limits, so the work runs through City of Raleigh Development Services under the 2018 North Carolina Residential Code.
This was a wear-and-overload failure, not weather. The roof already carried two full applications of asphalt shingles, the original plus an earlier re-cover, which is the legal ceiling. The 2018 North Carolina Residential Code (R908) bars a third layer over two existing applications, so any new roof here had to be a complete tear-off to the deck by code, never a quick recover. Worse, the doubled, heat-holding shingle mass sat over a builder attic with the ridge run choked and almost no balanced intake, so summer after summer the deck baked and could not breathe. Trapped moisture and twenty-plus years of thermal cycling had delaminated the OSB sheathing across the low-ventilation north plane, the soft, spongy feel the gutter crew noticed, while the south slopes facing the open fairway had burned out their granule and gone brittle under full unshaded sun.
The System We Installed
A complete tear-off of both layers down to the bare deck, then fourteen sheets of failed OSB swapped for new 7/16-inch sheathing and re-nailed to the rafters with 8d ring-shank nails on the prescriptive 6-inch-edge, 12-inch-field pattern (NCRC R803). Over the dried deck went a GAF Timberline HDZ architectural system in Charcoal: self-adhered ice-and-water membrane at the eaves and through every valley, synthetic underlayment across the full field in place of the old felt, new aluminum drip edge, and a 6-nail-per-shingle high-wind fastening pattern for the Wake County 115 mph design gust at Exposure B. The dead attic was opened back up with a continuous ridge vent paired with cleared soffit intake to hit the balanced 1/300 ratio, so the new deck finally breathes the way the assembly is meant to.
Timeline & Constraints
A free documented inspection inside 48 hours of the call, with the two-layer edge cut and the soft north-plane decking photographed and shown to the owners before any quote. Once the City of Raleigh permit was in hand, the tear-off, re-deck, and full re-roof ran a single working day with a six-person crew, one extra hand over a standard re-roof to carry off the doubled tear-off weight and set fourteen fresh sheets before the new system went down. A passing morning shower the day prior had soaked the old field, so the start held until the deck read dry on the meter, since new sheathing and underlayment never go over a wet substrate. The day closed with a magnetic nail sweep of the cul-de-sac and driveway, and the City of Raleigh final inspection cleared after.
The Outcome
Before: an over-layered, code-maxed roof with two stacked applications, fourteen sheets of rotting deck, a suffocated attic, and brittle sun-burned slopes that would have failed any honest listing inspection. After: a single clean architectural HDZ roof on sound new sheathing, with the attic finally ventilated to code and the leak-prone builder valley rebuilt with membrane underneath. Because this was a planned retail replacement and not a storm claim, there was no insurance carrier and no deductible involved, just a fixed written price the owners approved up front, which kept the whole job in their control. The finished roof carries Summit & Oak's 25-year workmanship warranty, which transfers once to the next owner, a documented selling point for a Brier Creek home heading to market where buyers shop move-in-ready and a roofer's paperwork answers the inspection before it is asked.
- Two complete shingle applications confirmed at the rake and eave edges, the original plus a prior re-cover, the legal maximum that triggers a mandatory full tear-off under NCRC R908 rather than a permitted recover
- Fourteen sheets of OSB roof sheathing delaminated and spongy across the shaded north plane, the panel edges swollen and the surface plies separating where trapped attic moisture never had a path out
- A choked ridge run with almost no working soffit intake, leaving the attic far short of the balanced 1/300 ventilation the code allows only when 40 to 50 percent of the venting sits high near the ridge
- Granule loss and brittle, sun-baked mat on the south and west slopes that face the open golf-course fairway with no tree canopy to shade them through Triangle summers
- The original builder valley laid as a closed-cut weave directly on felt with no ice-and-water membrane underneath, the seam most likely to leak first on a low-shaded plane
- Original 1.25-inch coil staples backing out of the field shingles on the over-layered slopes, a fastener pull-through the doubled weight only accelerated
