The Benefits Of Dry Fix Roofing Systems

For decades, mortar was the go-to solution for securing ridges, verges, and other roof details. But while mortar-based systems can do the job, they often come with long-term issues: cracking, loosening, and the need for regular repairs.

In recent years, the industry has shifted towards dry fix roofing systems—a modern, mechanical alternative that eliminates the weaknesses of mortar. And at Metrotile, we’ve embraced this change, offering dry fix solutions that are faster, cleaner, and more secure than traditional methods.

What is a Dry Fix System?

A dry fix roofing system uses mechanical fixings and interlocking components, rather than mortar, to secure ridges, hips, and verges.

For example, instead of bedding a ridge tile onto cement, a dry fix system uses:

• Clips, nails, screws, and support trays to lock tiles in place.

• Ventilation systems that allow airflow under the roof covering.

• Weatherproof components that provide lasting resistance against rain and wind.

Why the Shift Away from Mortar?

Mortar-based systems rely on cement to bed roof details in place. While initially strong, they’re prone to:

• Cracking due to temperature changes and natural movement in the roof.

• Water ingress where mortar has weathered or broken away.

• High maintenance, with costly repairs or repointing often needed.

• Time-consuming installation, requiring curing and careful finishing.

Building regulations and industry guidance now recommend more sustainable, long-term solutions—driving the popularity of dry fix systems.

The Benefits of Dry Fix Roofing Systems

Switching to dry fix brings a wide range of advantages:

1. Faster, Cleaner Installation

No mixing, no setting, no mess—dry fix is quick to install, reducing labour time and making projects more efficient.

2. Stronger and More Secure

Tiles tend to be mechanically fixed, meaning they stay firmly in place even under extreme wind uplift and severe weather conditions.

3. Low Maintenance

Unlike mortar, dry fix won’t crack or dislodge over time. That means less maintenance and fewer call-backs for homeowners or contractors.

4. Built-in Ventilation

Many dry fix systems, including Metrotile’s, are designed to improve roof ventilation. This helps prevent condensation and supports better roof performance by allowing a clear airflow path at the ridge and eaves of the roof.

5. Regulation Compliant

With roofing standards increasingly moving away from mortar, dry fix offers a future-proof solution that aligns with best practice and NHBC requirements.

Dry Fix with Metrotile

Metrotile’s lightweight steel roofing systems are designed to work hand-in-hand with our dry fix accessories. From ridge vents and eaves ventilation trays to barge covers that secure and protect verges, our solutions ensure every roof is:

• Fully ventilated to meet building regulations.

• Mechanically fixed individually by hand with nail guns or drills for maximum durability and storm resistance.

• Neat, clean, and professional in finish, enhancing kerb appeal.

And because Metrotile roofs are seven times lighter than traditional concrete tiles, installation is even faster, making dry fix the perfect partner for efficient, long-lasting roofing.

The Smarter Way to Roof

The industry’s move from mortar to mechanical fixing is no fad—it’s a response to the demand for stronger, longer-lasting, and regulation-compliant roofing.

With Metrotile’s dry fix systems, homeowners and contractors can enjoy all the benefits of modern roofing technology: faster installation, lower maintenance, and a secure roof that’s built to last.
