new roof in County Antrim (11)

If your roof is showing signs of age or persistent leaks, it might be time to consider a roof replacement.

Whether you’re dealing with cracked tiles, recurring damp patches, or storm damage, search for checked roof replacement services in Antrim with Checkatrade to restore your home’s protection and appearance.

What is roof replacement?

Roof replacement involves removing your existing roof covering — such as tiles, felt, or slate — and installing new materials to restore full protection against the elements.

In some cases, it may also include replacing damaged battens, underlay, or insulation.

Unlike small roof repairs, a full replacement ensures long-term durability, energy efficiency, and weather resistance.

Homeowners often choose this option when repairs are no longer cost-effective or when planning a major home renovation.

Roof replacement vs roof repair

While repairs can fix isolated issues like broken tiles or minor leaks, they may only be a short-term solution.

A full roof replacement is often needed when:

• Damage is widespread or recurring
• The roof is over 20–25 years old
• There are visible gaps or daylight in your loft
• Multiple layers of repairs have already been applied

In the long run, a replacement often proves more cost-effective and energy efficient.

Timings: How long does roof replacement take?

Most roof replacements take between 3 and 7 days, depending on roof size, materials, and weather conditions.

• Flat roofs may take just 1–2 days
• Pitched or slate roofs typically require 5–7 days
• Large or complex roofs with dormers or chimneys may take longer

Checked roofers plan around weather forecasts and use tarpaulins to protect your home in case of unexpected rain.

How long does a new roof last?

The lifespan of your new roof depends on the material used and the quality of installation. On average:

• Felt roofs last around 15–20 years
• Concrete or clay tiles can last 40–60 years
• Slate roofs may last over 100 years
• Metal roofs can last up to 70 years

Regular maintenance — such as clearing moss and checking flashing — can help extend the life of your new roof.

What should be included in your quote?

• Accreditation from NFRC (National Federation of Roofing Contractors) or similar bodies
• Valid and adequate public liability insurance
