Windshield Repair in Winston-Salem, NC: Rock Chips Filled at Your Car

Auto Glass Winston-Salem is Impex Auto Glass serving Winston-Salem, so the repair is done where your car is: at home, in an office lot or in an apartment parking space. This page covers which chips can be filled, how a repair is done, what it looks like afterward and how insurance usually treats it in North Carolina.

The kinds of chip a stone leaves

Glass people name chips by their shape, and the shape says something about how well the repair will go. Knowing the names helps when you describe the damage on the phone or in the form.

Name	What it looks like	How it usually repairs
Bullseye	A round, cone-shaped break with a dark circle	Well, when it is clean and filled early
Star break	A small impact point with short legs running out from it	Well, if the legs are short; long legs make it a crack job
Combination break	A bullseye with legs, the most common chip from road stones	Usually well, within the size limits
Half moon	A partial bullseye, like a semicircle	Usually well
Pit	A tiny missing flake with no cracking around it	Often left alone unless it is in the driver’s view

Which chips can be repaired

Three things decide it: the size of the break, how deep it goes, and where it sits on the glass. Impex’s own rule is that a repair may be possible when the chip or crack is small, shallow and away from the edges of the windshield.

For size there is an industry standard. ROLAGS, the Repair of Laminated Automotive Glass Standard administered by the National Windshield Repair Division, says ‘Stone-breaks up to two inches in diameter and single line cracks up to 14-inches are repairable.’ Those are outer limits. Day to day, shops use simpler rules of thumb: one widely used rule says damage smaller than a dollar bill, about six inches, is likely repairable, and Impex describes small chips as those smaller than a quarter. A rule of thumb is a starting point, not a promise: the technician decides at the glass.

• Size. A chip under the size of a quarter is the easy case. Up to about two inches across is inside the ROLAGS limit.
• Depth. The break should be in the outer layer of glass. If the stone went through to the plastic layer or the inside layer, the windshield needs replacing.
• Position. A chip at the very edge of the glass sits where the windshield is bonded to the car and tends to run. A chip right in front of the driver may leave a visible mark after repair, so a new windshield is often the better answer there.
• Age and dirt. A fresh, clean chip takes resin better than one that has filled with grime and water over months.

Why a chip spreads, and why sooner is cheaper

A chip is a weak point in a sheet of glass that is under stress all the time. The glass expands in the sun and contracts in the cold. It flexes over bumps, expansion joints and railroad crossings. A door slammed with the windows up pushes on it. The edges of the chip are where all of that stress collects, so the chip that sat still for three weeks can run a foot across the glass on the morning you blast the defroster.

Piedmont driving gives a windshield plenty of that. A car parked all afternoon in an open lot near Hanes Mall Boulevard, then cooled hard by the air conditioning on the way home along Silas Creek Parkway, or a frosted windshield on a cold morning on University Parkway: those swings are what turn chips into cracks. The fix is cheap compared with a new windshield, so the earlier the better.

What to do until the repair

• Put a piece of clear tape over the chip to keep dirt and water out of it.
• Do not pour hot water on frosted glass, and do not aim the defroster straight at the chip on full heat.
• Avoid the car wash until the chip is filled: high-pressure water and soap push into the break.
• Close doors gently, with a window cracked if you can.
• Take a photo with a coin beside the chip for scale. It helps Impex tell you from the quote form whether it looks repairable.

How a windshield chip repair works

A resin repair is a short job, done at your vehicle without taking anything off the car. In outline:

1. Look and decide. The technician checks the size, depth and position of the chip and confirms it can be repaired before starting.
2. Clean the break. Loose glass and dirt are taken out of the impact point so the resin can reach every leg of the chip.
3. Fill. A tool is fixed over the chip and resin is drawn into the break under pressure, pushing out the air that makes a chip look dark.
4. Cure. The resin is hardened so it bonds the glass on both sides of the break.
5. Finish. Any extra resin is scraped level with the surface and polished, and the technician checks the result.

A repaired chip does not vanish. Expect a faint mark where the stone hit, much less visible than the open chip. What matters is that the break is sealed and stable. If a repair is not possible, the technician will say so before starting, and the job becomes a windshield replacement.

Why Winston-Salem windshields take stones

Winston-Salem sits where I-40, I-74, I-285 and US 52 meet, with Salem Parkway running south of downtown. That means a steady stream of trucks, and highway work zones where loose gravel collects on the shoulder. North Carolina treats loose stone as a road hazard: under G.S. 20-116(g), no vehicle may be driven with its load able to fall, blow or sift out, and trucks over 7,500 pounds carrying rock, gravel or stone must keep the load six inches below the walls and covered by a tarpaulin or similar cover. Not every load is covered well, and tires throw up gravel from the shoulder all the same.

Following distance helps more than anything. A stone thrown from a tire ahead loses height and speed with distance, so the extra car length behind a dump truck on US 52 is worth it. If you see a load uncovered, give it more room.

Chip repair and insurance in North Carolina

Glass damage from a stone normally falls under comprehensive coverage. The NC Department of Insurance lists ‘breakage of glass’ and ‘missiles or falling objects’ among comprehensive losses, and says comprehensive pays the repair less any deductible. North Carolina has no law that waives the deductible for glass. Some policies include full glass coverage; check yours or ask your agent. Because a chip repair costs far less than a windshield, it often comes in under the deductible, in which case many drivers simply pay for it.

• Your choice of shop. G.S. 58-3-180 says a policy covering damage to a motor vehicle must let you select the repair service, and the insurer pays the same whichever you choose.
• Points. A rock chip is not an at-fault accident, so a comprehensive glass claim does not add Safe Driver Incentive Plan points. Your insurer may still look at how often you file claims.
• Help with the paperwork. Impex works with all major insurance providers. Have your insurer’s name and policy number ready when you ask for the quote.

Chips and the NC safety inspection

North Carolina’s annual safety inspection, set out in G.S. 20-183.3, checks the windshield wipers, not the glass itself, and no NC statute sets a chip or crack size. That is not a reason to leave a chip alone. A break that runs into a crack in front of the driver is a safety problem whatever the inspection says, and it turns a short repair into a full windshield.

When the windshield has to be replaced

Some damage is past filling: a chip that went through the outer layer, a crack that reached the edge, or a break right in the camera’s field of view. Then the windshield comes out, a new one checked against your VIN goes in, and the forward camera is calibrated if your car needs it. The pages on windshield replacement in Kernersville, NC and windshield replacement in High Point, NC cover that job in full.
