Ordering a rooflight online can feel like a big step, especially if you’re not entirely sure what to look for. But with the right guidance, it’s a smooth and straightforward process that can completely transform your space. Whether you’re working on a home renovation, a flat roof extension, or a loft conversion, a well-chosen rooflight will flood your room with natural light and add a modern architectural feature. In this guide, we’ll walk you through everything you need to know to order the perfect rooflight online, from measuring and choosing the right style to understanding specifications and delivery.

Why Order a Rooflight Online?

Online ordering has become the go-to method for sourcing home improvement products, and rooflights are no exception. With detailed product information, sizing guides, and a wide range of customisation options, you can browse and buy at your own pace, all from the comfort of home.

The key is knowing what to look for and making sure your choice fits your space, style, and budget.

1. Understand Your Space

Before you start browsing, take a moment to consider where your rooflight will go. Is it for a flat roof extension, a new build, a loft conversion, or even a garden room? This will help determine what type of rooflight is best.

For example:

• Flat roofs usually suit flat rooflights or walk-on units.
• Extensions or open-plan kitchens benefit from larger fixed or opening flat rooflights for maximum light and impact.

Also consider what the room is used for. A kitchen or bathroom might benefit from a vented rooflight to help with airflow, while a living room might just need fixed glazing for extra daylight.

2. Measure Correctly

Accurate measuring is crucial. When ordering online, most suppliers will ask for the structural opening size, this is the size of the hole in the roof where the rooflight will be installed, not the size of the glass or frame.

Here are some tips:

• Measure the width and length of the opening from timber to timber.
• Double-check your measurements to avoid ordering the wrong size.
• If you’re unsure, consult your builder or installer, many online retailers will also offer measuring guides or customer support to help.

If you’re replacing an existing rooflight, you can measure the current one to match, but always confirm whether the listed sizes are external frame sizes or internal opening sizes, they are not the same.

3. Choose the Right Style

There are several rooflight styles available, and your choice will depend on your goals and roof type. Common options include:

Fixed Roof Lights

These don’t open and are purely for letting in natural light. Ideal for living rooms, hallways, or anywhere that doesn’t require ventilation.

Opening Rooflights

These offer ventilation and are available with manual or electric opening mechanisms. Perfect for kitchens, bathrooms, or hot rooms.

Roof Lanterns

Although technically these aren’t rooflights, they add height and a traditional aesthetic.

Each style will suit different needs, if in doubt, check the product usage recommendations listed on most supplier websites.

4. Think About Glazing Options

Not all glass is created equal. When choosing your rooflight, take time to review the glazing specs. Some of the most important features to consider include:

• Double or triple glazing: Triple is more energy-efficient, but heavier and pricier.
• Low U-values: The lower the U-value, the better the insulation.
• Solar control glass: Helps reduce glare and overheating in sunny rooms.
• Self-cleaning glass: Great for hard-to-reach rooflights, as it reduces maintenance.
• Toughened or laminated glass: Important for safety and security, especially for large rooflights.

5. Decide on Frame Colour and Finish

Frame finish can impact the overall look of your space. The most common option is anthracite grey, which gives a modern, minimalist look and pairs well with aluminium bifolds and windows.

However, many manufacturers also offer:

• Black or white finishes
• Dual colours (different internal and external colours)
• Bespoke RAL colours (at additional cost)

If the rooflight is visible from below, think about how it will look from the inside too, white internal frames often help keep the interior feeling bright and clean.

6. Check for Ventilation Options

If you need airflow in the room, you’ll want a vented rooflight. Online retailers will usually indicate whether a model opens manually or electronically.

This is especially important for kitchens, bathrooms, or anywhere with rising heat or steam.

7. Compare Brands and Quality

There are many rooflight manufacturers on the market. When buying online, look for brands with a reputation for quality and independent certifications (like BSI approval).

8. Review Lead Times and Delivery

Lead times for rooflights vary depending on whether you’re ordering a stock size or a custom-made product. Standard sizes may ship in a few days, while made-to-order rooflights might take 2–4 weeks or longer.

Check:

• The estimated lead time at checkout
• Delivery cost (some retailers offer free UK delivery)
• If someone needs to be on-site to receive it

Rooflights are large, fragile items, so make sure your builder knows when to expect it and has people on-site to receive and handle it safely.

9. Ask About Installation Guides

While most people will have a builder or roofer install the rooflight, it’s still important to review the product’s installation process. Online listings will usually include downloadable installation guides, useful to share with your contractor ahead of time.

Also check:

• Whether fixings or upstands are included
• If you need to prepare a timber upstand or curb in advance
• The minimum pitch requirements for water run-off (important on flat roofs)

Some suppliers also offer installation services or can recommend trusted fitters in your area.

10. Place Your Order Confidently

Once you’ve confirmed your size, style, glazing, and delivery options, you’re ready to order. Take a final moment to review:

• All your chosen customisations
• Product guarantees
• Return policies, just in case

Save your confirmation email and keep in touch with the supplier in case your delivery schedule changes.
