Rooftop gardens can become a getaway in a busy city environment. Whether you fill them with plants or plan to entertain, this guide will help you create the perfect lighting design scheme for your rooftop garden.
Benefits of Lighting Your Rooftop Garden Area
Lighting your garden can transform it into a space you love to spend time in. Whether you use it for some alone time or like to host guests, lighting for a rooftop terrace is important to get right.
Good lighting can create a nice atmosphere and set the mood in the space. Choosing string lights, warm-toned illumination and subtle wall lights can completely transform the space into something dreamy and inviting.
It also has the practical benefit of extending the use of your rooftop space into the night. Outdoor lighting can also enhance the safety and visibility when you are using it after dark.
With accent lighting, you can highlight the architectural features and plants that are up there as well. Wall washers, spike lights and recessed uplights can show off columns, vertical gardens and beyond.
If you one day plan to sell your property, having quality rooftop garden design may improve the property value. This is especially true in urban locations where outdoor space is prized.
How to Light Different Zones and Functional Areas of a Rooftop Garden
A rooftop can have many different use cases, and having lighting in each of the areas can make them come to life. Below are some tips on how to light the rooftop space for certain areas.
Dining and Entertainment
For social rooftop spaces, you should create an atmosphere that is warm and inviting. Pendant lights over dining tables, string lights over seating areas and warm light throughout are your best bets.
Plants and Greenery
Using accent outside lighting, you can draw attention to the beautiful plants you have on the roof. Hanging lights, vertical gardens, and potted plants can all be enhanced with properly placed lighting.
Steps and Pathways
In areas meant to help navigate the rooftop, having step lights and other low level rooftop patio lights can make it easier to move around. Use glare-free light fixtures to make it easier to see while avoiding harsh shadows.
How to Layer Lighting in a Rooftop Lighting Scheme
Layered rooftop terrace lighting is the process of layering ambient, task and accent lighting together. This creates a more balanced and even visual appeal.
Ambient light is the main foundation of lighting in a space. It provides the base illumination that your other outdoor rooftop lighting can then supplement. Wall lamp outside fixtures with bright lumen counts, or overhead exterior lamps work well for this layer.
Task lighting provides more focused illumination for certain activities. They are ideal for areas used for cooking and dining. Hanging outdoor LED ceiling lights above a table or placing exterior step lights along pathways will create a solid task layer.
Finishing off the layered lighting scheme is accent lighting. Accent lights highlight and accentuate different areas in the rooftop space. Using spotlights, uplighters and outdoor up and down wall lights, you can show off different features in the space.
Different Design Ideas for Rooftop Gardens
Rooftop lighting ideas are many, and the right one for you all depends on the personality you want to express and communicate in your rooftop garden. Below are a few ideas to get you started.
Modern Entertaining Area
While the best lighting for rooftop entertaining will vary, contemporary spaces can all benefit from similar lighting principles. Having sleek lines and crisp angles with your lighting and decor will give off a clean, minimalistic design.
LED strip lighting hidden behind counters and under benches will provide lighting without exposing the actual fixture, instantly giving a more modern look.
Urban Jungle
You can make your rooftop into a dense, green area with layered planting and plenty of natural textures. Raised planters that have ferns and grasses paired with climbing vines can bring a breath of fresh air to city rooftops. Choose outdoor spike lights hidden among the plants and uplights to show off any vertical gardens.
Wellness Gardens
Create a tranquil escape with zen-inspired gardens. Think stepping stones, gravel paths and water features for a peaceful getaway. Diffused wall sconces and low-level exterior bollard lights will provide a soft glow that creates a calming environment.
Top Mistakes to Avoid When Lighting a Rooftop Garden
When considering how to light a rooftop garden at night, it is easy to focus purely on aesthetics of the lights themselves and make mistakes in other places. By getting familiar with some of the more common mistakes people make, you can get ahead of them and avoid renovations down the line.
Overcomplicating the Lights
Especially in terms of rooftop garden lighting for small spaces, adding too many lights can be a detriment. Your instinct may be to add as many light fixtures as you can to ensure even brightness, it is best to layer lights strategically.
You should also avoid mixing colour temperatures and too many different finishes. By having too many lights of different styles, you may also accidentally create a sense of visual clutter.
Forgetting About Glare
Glare is a quick way to ruin the ambiance of your outdoor garden. By neglecting to consider reflective surfaces or not choosing glare-free lighting, you can cause abrasive illumination that does more harm than good.
Avoid mounting exterior wall lamp fixtures at eye level or using exposed bulbs near seating areas. You should also take care to ensure in ground lights do not point directly at reflective surfaces.
Neglecting IP Ratings
By not choosing lights with the appropriate IP ratings, you will have to replace them more often. Choose waterproof lights with a rating of IP65 or above for best results.
Not Using LED Lights
Energy efficient rooftop lighting solutions will last you a lot longer than traditional halogen bulbs or incandescent bulbs. They use 80 percent less energy than their conventional counterparts, giving not only a longer life but also reducing the cost of their usage.
Tips on Choosing the Right Colour Temperature
Colour temperature, sometimes just called CCT, is how the coolness or the warmth of a light is indicated. Colour temperatures are measured in Kelvin units and exist on a scale between 1,000 and 10,000.
Warmer colour temperatures are found toward the bottom of the spectrum. Cooler colors have higher Kelvin ratings. Both colour temperatures have their place and time. For most people, warm colours and residential lighting go hand in hand.
Lighting for rooftop entertaining can go either way. If you want to create a more relaxing, toned-down space, warm lighting is ideal. Opt for temperatures between 2700K and 3300K for the right blend of warmth and visibility.
If you want something more modern and energising, cool lighting may be preferred. Lights between 4000K and 6000K create a more vibrant location and a modern atmosphere.
Does IP Rating Matter When Lighting a Rooftop Area?
IP ratings, or Ingress Protection ratings, are metrics used to discuss how well a light is able to resist damages from solids and moisture. It consists of two digits: the first digit measures resistance to solids, while the second refers to its resistance to moisture damages.
When it comes to outdoor lighting, waterproof lighting for rooftop gardens is essential. Even if part of the roof is under a covering, you still need to protect it. This means having IP rated lighting isn't really negotiable.
For outdoor spaces, it is recommended that you choose light with an IP rating of IP65 or above. This will provide waterproof protection so you can be sure even on rainy days your lights are safe.
Why You Need to Consider Light Pollution When Designing the Lighting Scheme
Light pollution is one of the things you need to look out for when designing your garden lighting. Too much light and poorly planned placement can cause illumination to bleed out into the night and potentially other people's property.
This can disrupt nearby ecosystems while also obscuring views of night skies. It is generally considered inconsiderate to have too much light pollution coming from your property.
Since rooftop gardens are often elevated and exposed, they come with additional responsibility to their surroundings to not pollute them with light. In order to reduce light pollution, consider shielded fixtures that control the spill of light.
You can also opt for lights with lower lumen counts, and use indirect light sources like recessed outdoor wall lights to limit the amount of illumination in use. By choosing lights with warmer colour temperatures, you are also less likely to disrupt those around you.
With the lights on smart controls and timers, you have finer control over the amount of light in the area as well as when it shines. You can also make yourself familiar with Dark Sky guidelines and design your rooftop lighting scheme in accordance.
Ways to Create Evening Ambiance
Rooftop garden ambiance is a goal for many when it comes to rooftop lighting design. Beyond practicality from fixtures like pathway lights, you can use this space to tell a story and express personality.
For example, putting a pool of light near the entrance can set a tone for the rest of the experience. Add in scene transitions with various brightness levels in order to create visually distinct zones.
You can create depth and visual drama using light and shadow together. Placing mirrored planters and glass fixtures near lights can amplify the illumination and add lots of sparkle. Conversely, adding shadow-casting fixtures can balance out that glow and create visual drama.
It is recommended when creating an ambiance that you limit the number of colours you are using. Less is more when it comes to ambiance, so stick to simple amber or blush tones for relaxed spaces and blue or greenish hues for modern, spa-like areas.
Think about the different times of day and how the light will naturally play into it as well. For example, during golden hour, warm tones will be amplified and you can supplement with softer glows. During twilight, you may want to introduce softer ambient sources and accent lighting.
