Should Roofing Nails Be Exposed? Expert Advice for Homeowners in Clare, Galway & Limerick

No, roofing nails should never be exposed. Exposed nails create openings for water to seep into your roof, leading to leaks, wood rot, and long-term structural damage. Properly installed nails are always covered by the shingle above. If a nail becomes exposed, it must be sealed with roofing cement to prevent rust and loosening.

Why Exposed Roofing Nails Are a ProblemWhy Exposed Roofing Nails Are a Problem

Roofing nails may look small, but they play a critical role in keeping your roof watertight. When they are left uncovered, several problems can develop quickly:

• • Water Damage – Rainwater and melting snow follow the path of least resistance. An exposed nail is essentially a direct channel into your roof structure.

• • Rust and Corrosion – Metal exposed to the elements will corrode. As nails rust, they lose their holding strength and can start to back out of the decking.

• • Shingle Damage – A loose nail can lift surrounding shingles, making them more vulnerable to high winds and further water penetration.

• • Structural Risk – Over time, hidden leaks can rot the roof decking or even the rafters, leading to expensive repairs.

What starts as a minor issue can quickly escalate into a major roofing failure if not addressed.

Proper Installation of Roofing Nails

Professional roofing contractors know that nail placement is key to roof performance. A properly installed nail should be:

• • Placed under the overlapping shingle, never exposed to weather.

• • Driven in straight and flush with the shingle surface (not angled or overdriven).

• • Hidden by the next course of shingles for a watertight seal.

Following these best practices ensures that every nail is protected from rain, wind, and UV damage. Poor workmanship or rushed installations are the most common causes of exposed nails.

How to Cover Exposed Roofing Nails in Clare, Galway & Limerick

Homeowners in the west of Ireland know how tough our weather can be. Between heavy Atlantic rain in Galway, strong winds along the Clare coastline, and the freeze–thaw cycles common in Limerick, even the smallest exposed nail can become a big problem if it isn’t sealed properly.

Here’s a step-by-step guide on how to cover exposed roofing nails safely:

1. Find the Exposed Nails

• • Walk the perimeter of your home and look at your roof from different angles.

• • Common problem spots are ridge caps, flashing around chimneys, and roof edges where strong winds are frequent in places like Shannon or Ennis.

2. Clean the Nail Area

• • Use a wire brush or cloth to clear away moss, dirt, or grit (which are common on Irish roofs due to damp conditions).

• • A clean surface helps the sealant stick properly.

3. Apply Roofing Cement or Sealant

• • Place a small dab of roofing cement directly over the nail head.

• • In wetter regions like Galway, we recommend a cement that stays flexible and won’t crack in cold weather.

• • Cover slightly beyond the nail to create a watertight seal.

4. Add Extra Protection if Needed

• • If the exposed nail is on a ridge cap or hip line, cut a small patch from an extra shingle.

• • Press it over the nail with cement underneath for double protection.

• • This method is especially useful in areas exposed to high winds off the Atlantic.

5. Inspect After Storms

Check the repaired area after heavy rain or high winds to make sure the cement hasn’t cracked or washed away.

In the west of Ireland, storms can hit hard and fast.

What To Do If You See Exposed Nails

If you notice exposed nails on your roof, act quickly:

• • Seal with roofing cement.

• • Inspect common trouble spots like flashing and ridges.

• • Call a professional roofer for long-term repairs and peace of mind.
