Roof Ridge Cap Repair in Clarksville, TN

We have been replacing ridge caps in Clarksville since 2003. After every wind event, we get

calls for missing or lifted ridge caps. Homes o Fort Campbell Blvd are especially vulnerable

because they are exposed to open elds. The wind has no bu er.

Here is what happens. A storm rolls in o the Red River. The wind gusts hit 60 mph. The ridge

cap lifts at the edge. The nails pull through. The cap aps. Then it tears o completely. The

homeowner does not notice until they see the black ridge vent exposed.

If you ignore a missing ridge cap, water will get in. It might take a few storms. But eventually,

rain will drive into the ridge vent. It will drip onto your attic insulation. That insulation will get

wet and moldy. Then your ceiling will stain. A $240 repair becomes a $1,500 repair.

This article covers roof ridge cap repair in Clarksville. What it is. Why it fails. How we fix it. And

why you should not ignore it. Call (931) 666-1469 for a free estimate.

What Is a Ridge Cap and Why Does It Fail in Clarksville?

The ridge cap is the shingle that covers the peak of your roof. It is cut from standard shingles

or purchased as pre-formed ridge caps. It is nailed over the ridge vent or directly over the

peak. In a proper installation, each cap overlaps the one below it. The nails are covered by the

next cap. The last cap gets a dab of roofing cement on each nail head.

Ridge caps fail for three reasons. First, wind. Clarksville's spring thunderstorms produce

straight-line winds that can hit 70 mph. Those gusts get under the edge of the first cap and lift

it. Once one cap is loose, the others follow.

Second, improper installation. Some roofers use only 4 nails per cap instead of 6. Some use a

nail gun set too deep, which breaks the shingle. Some skip the roofing cement on the final cap.

We see these mistakes on roofs installed by storm chasers.

Third, age. After 10 to 12 years, the asphalt in the ridge cap becomes brittle. The shingle loses

exibility. A gust that would just lift a new cap will snap an old one in half. We see this on

homes o Tiny Town Road that are approaching 20 years old.

Signs of ridge cap failure: missing caps, lifted caps (you can see daylight under them), cracked

caps, or visible nail heads. If you see any of these, call us.

Fort Campbell families, ridge cap damage is common on base housing after wind events. The

housing office has a maintenance crew, but they use us for large repairs.

How We Repair Ridge Caps (Step by Step)

A: You can, but working on a ladder at the eaves is dangerous. You also need to ensure proper

ventilation. And you need to rehang gutters with the correct pitch. We have seen DIY so t

repairs that blocked attic ventilation and caused ice dams. Hire a pro.

1. Inspection. We walk the entire ridge line. One missing cap often means others are loose.

We check each cap by trying to lift it. If it lifts easily, the seal has failed.

1. Remove damaged caps. We pull o loose, cracked, or missing caps. We remove the old

nails. We clean the area of debris.

1. Check the ridge vent. If you have a ridge vent, we inspect it. Ridge vents are plastic or

metal. They can crack or get dented by hail. If the vent is damaged, we replace that section.

Cost is $50 to $100 per 4-foot section.

1. Cut new ridge caps. We use matching shingles from the same batch if available. If not,

we use the closest match. We cut each cap to size (typically 12 inches wide). We use a hook

blade to avoid damaging the shingle below.

1. Install the first cap. We nail it with 4 nails (2 on each side). We make sure it is centered on

the ridge. We do not overdrive the nails.

1. Install subsequent caps. Each cap overlaps the previous cap by at least 2 inches. Each

cap gets 4 nails through the overlap. The nails are hidden by the next cap. We stagger the nail

pattern to avoid splitting.

1. Install the final cap. The last cap gets 6 nails: 4 through the overlap, plus 2 through the

exposed end. We hand-seal each nail head with roofing cement. We also seal the edges of the

final cap.

1. Seal all exposed nails. For any cap where a nail is visible (rare if done correctly), we dab

cement on it.

1. Clean up. We remove old cap debris. We magnet for nails.
2. Test (optional). For roofs with ridge vents, we run a hose along the ridge to ensure no

water gets in. We do this on the first rain after repair.

Why Hire a Local Clarksville Roofer for Ridge Cap Repair?

A handyman can nail up a ridge cap. But will it stay? Probably not. We use the correct nailing

pattern (6 nails per final cap). We hand-seal each nail head with roofing cement. A handyman

might use 4 nails and no cement. That cap will blow o in the next storm.

We also match your shingles. Ridge caps cut from a different batch of shingles will look slightly

different. We carry samples. We show you the match before we cut.

For Fort Campbell families, we offer same-day ridge cap repair. It is a quick x that prevents

bigger problems. We can usually be at your home within 24 hours of your call.
