A documented roof replacement project in Knightdale, NC, start to finish.
Roof Replacement in Knightdale, NC
The original 2009 builder roof on this Mingo Creek home had reached end of life, with brittle shingles failing first on the wind-exposed east plane. As first-time roof buyers, the owners got a line-by-line walkthrough before we tore off and installed a 30-year architectural system with upgraded synthetic underlayment. Permitted through the Town of Knightdale building services and finished in a single day, with every nail swept from the cul-de-sac.

The Situation
A two-story 2009 builder home in the Mingo Creek subdivision, on a quiet cul-de-sac off the wooded greenway corridor that runs down to Mingo Creek Park and the Neuse River bottomland east of Raleigh. The original owners had bought the house new and had never replaced a roof, so when the east-facing slope started shedding granules into the gutters and a neighbor two doors down had just re-roofed, they called Summit & Oak to learn whether 15 years was simply the end of a builder roof or something that could be patched. The home sits inside Knightdale town limits, so the work falls under the Town of Knightdale Building Services and the 2018 North Carolina Residential Code, with Wake County as the backstop for the unincorporated parcels nearby.
This was not storm damage, it was a builder-grade roof reaching the honest end of its service life. The original system was an entry-level architectural shingle, the kind production builders installed across whole Mingo Creek streets around 2009, and after 15 Carolina summers the asphalt mat had dried, the granule blanket had thinned, and the shingles had gone brittle and curl-edged. A choked, under-vented attic accelerated it: intake at the soffits was partly blocked and there was too little exhaust near the ridge, so summer attic heat baked the underside of the deck and cooked the shingles from below faster than weather alone would have. The east slope, which caught the most direct afternoon sun and the open prevailing wind across this lightly canopied side of East Wake, simply aged first and hardest. Replacement, not repair, was the truthful call.
The System We Installed
Full tear-off to the sheathing, then a complete GAF Timberline HDZ architectural system installed to the 2018 NCRC. A self-adhered ice-and-water membrane went down at the eaves and in the valleys, synthetic underlayment replaced the old felt across the field, new aluminum drip edge was set at the eaves and rakes, and the shingles were fastened six nails per shingle to hold the upgraded ASTM D7158 wind-resistance class for the Wake County 115 mph Exposure B design speed. The two soft east-deck sheets were cut out and replaced with new OSB and re-nailed with 8d ring-shank nails before the underlayment went on. New pipe-boot collars sealed the penetrations, and the ventilation was corrected: soffit intake cleared and a continuous ridge vent added so 40 to 50 percent of the net free area now sits in the upper portion within three feet of the ridge, the way the code intends, so the new roof breathes instead of baking.
Timeline & Constraints
A free documented inspection the day after the call, with every slope and the attic shot on dated photos and a plain-English, line-by-line walkthrough of the estimate for first-time roof buyers who had never seen one. The tear-off and full re-roof ran a single working day with a five-person crew. An early-fall passing shower in the forecast set the start time, so the crew staged the tear-off to keep no more open deck than could be dried-in and underlaid before the afternoon, and the east slope was underlaid first as the priority plane. The job closed with a magnetic nail sweep of the cul-de-sac, the driveway, and the beds, then the Town of Knightdale final inspection cleared.
The Outcome
Before: a brittle, granule-shedding 15-year builder roof with curled tabs, soft deck spots, and an attic cooking itself from the inside. After: a clean architectural HDZ roof rated to the current wind class, a corrected, code-compliant ventilation path that will let this roof reach its full service life instead of aging early, and two first-time owners who understood every line of what they bought before a nail went in. Because this was end-of-life replacement and not a storm claim, there was no insurance involved, no deductible, and no coverage outcome to promise, just an honest repair-or-replace answer and a fair price. The finished roof carries our 25-year workmanship warranty, which transfers once to a new owner, a real resale signal on a Mingo Creek street where most of the block is heading into this same first-replacement window.
- Widespread granule loss with bare asphalt mat showing on the east plane, granules washed into the gutters and the cul-de-sac storm inlet, the classic end-of-life signature on a 15-year builder shingle
- Curled and clawed tab edges across the sun-exposed slopes that no longer lay flat or sealed, brittle enough that several cracked when lifted by hand during the walkthrough
- Soffit intake vents partially blocked by paint and insulation and too little exhaust near the ridge, well short of the 40-to-50 percent upper-portion split the 2018 NC code expects, leaving the attic to overheat and cook the deck from below
- Two soft spots on the east deck near a plumbing penetration where years of heat cycling and a tired pipe boot had let moisture work into the OSB sheathing
- Dried and cracked pipe-boot collars and lifted aluminum drip edge at the rake, minor on their own but consistent with a system past its useful life
- Only a single shingle layer present, so a full tear-off to the deck was the right path under the NC two-layer limit rather than a second layer over failing shingles
