How to Replace Your Polycarbonate Conservatory Roof with a More Durable and Energy-Efficient Option

If you have a conservatory with a polycarbonate roof, you may have noticed it becomes brittle and discoloured over time, leaks during heavy rain, and lacks sufficient insulation. Replacing it can greatly enhance your conservatory’s durability, energy efficiency, and aesthetics. Read on to learn why swapping out that ageing polycarbonate for glass, tile, or slate is worthwhile, what the best replacement options are, step-by-step instructions for installing a new roof, and additional upgrades that boost energy savings.

Problems with Polycarbonate Roofing

Polycarbonate roof sheets were once thought to be a durable glazing choice, but they have some inherent flaws:

  • They become brittle and degraded from UV exposure after around 5 years, with discoloration and even small fractures. This leads to leaks.
  • They lack multi pane or vacuum-insulated options. Heat loss and gain is significant in both winter and summer.
  • The roof requires replacement long before the rest of the conservatory structure. Repeated roof replacements are troublesome and costly.
  • They have an unattractive look that worsens over time as sheets age, crack, or get dirty.

Why Replace Your Polycarbonate Roof

If your polycarbonate roof is more than a few years old, replacing it offers three major upsides:

Improved Durability

Premium materials like glass, slate, and tile roofs can last upwards of 50 years or longer without replacement. This avoids repeat roofing jobs.

Better Energy Efficiency

New glazing or vacuum-insulated panels cut heat transfer significantly compared to single-pane polycarbonate. This slashes energy costs.

Lower Maintenance

Upgraded roof materials are more resilient against damage and environmental wear-and-tear. You’ll spend less on cleaning and repairs.

Best Replacement Roofing Options

When selecting a replacement conservatory roof, the three top options to consider are:

Glass

Tempered safety glass avoids the fragility of polycarbonate. Multi Pane thermal insulation glazing adds excellent temperature and sound insulation too.

Tile

Clay or concrete roof tiles are extremely durable against the elements. Their natural insulation properties also aid energy savings.

Slate

Natural slate roofing lasts over a century when properly installed. It comes in various tints to control heat gain versus natural light transmission.

How to Replace Your Polycarbonate Roof

Replacing a conservatory roof requires careful planning and execution:

Check Local Building Codes

Most jurisdictions require permits for structural work like roof replacement. Research local regulations first.

Hire a Professional Roofer

While DIY roofing is possible for advanced renovators, it’s complex and risky. Consult a qualified professional roofer.

Prepare the Roof for Replacement

Remove all existing polycarbonate panels, flashing, gutters and debris. This exposes the roof structure for rebuilding.

Install Underlayment and Flashing

Apply weatherproof, heat-reflective underlayment across the roof. Integrate flashing around intersections.

Install New Roofing Material

Finally, attach your new glazed panels, slate sections or tiles row-by-row per the manufacturer’s instructions.

Improving the Rest of Your Conservatory for Energy Efficiency

To maximise energy savings along with your new roof, also upgrade:

Insulate the Walls and Floors

Add insulation batting within wall cavities plus under flooring. Reduce conduction heat transfer.

Install Double Glazing

Swap out old single pane glass conservatory windows for new double or triple glazing. Further curtail heat loss.

Add a Conservatory Heater

Install a dedicated heater to warm the conservatory efficiently on demand during cold weather. Maintain ideal warmth.

Conclusion

Replacing an ageing, leaky polycarbonate conservatory roof with a modern glass, tile or slate alternative not only restores structural integrity, but also boosts durability exponentially, cuts energy bills significantly through better insulation, and improves aesthetics. With proper planning and setup, the upgrade process need not be overly complex. Pairing your new roof with added wall/floor insulation, glazing upgrades and a conservatory-specific heater takes energy savings to the next level. Your conservatory will become a comfortable, visually stunning space you can enjoy year-round for decades to come.

FAQs

What are the main benefits of replacing a polycarbonate conservatory roof?

The main benefits are improved durability, better energy efficiency, lower maintenance costs, and enhanced aesthetics over time. High quality replacement roofs last many decades.

How much does it cost to replace a conservatory roof?

In most cases it costs £3,500 – £6,000 to replace a conservatory roof depending on the size, chosen materials, complexity of the project and your location. Professional installation is recommended.

What are the best conservatory roof replacement materials?

The best options are tempered safety glass, clay or concrete tile, and natural slate shingles. All offer exceptional longevity and good insulation. Glass also provides excellent natural daylight.

Can I install a replacement conservatory roof myself?

It is possible for skilled DIYers to self-install a new conservatory roof, but due to the complexities involved most homeowners utilise a professional roofer for a safe, legally compliant installation.

How long does it take to replace a conservatory roof?

The total project duration varies based on size but allows 2-4 weeks: 1 week for tear-off, preparation and setup; 1-3 weeks for the actual roofing installation. Be sure to check local building codes first.
