6 Common Rooflight Installation Mistakes to Avoid

May 30, 2024

Rooflights are an innovative and stylish way to increase natural lighting in your home. However, if they’re not installed correctly, they won’t stand the test of time.

The installation process goes beyond cutting a simple hole in your roof. Today, TuffX will walk through the most common pitfalls when installing rooflights to help you avoid a faulty fixture.

This will ensure seamless beauty and flawless performance for a light and airy home.

1. Choosing the Wrong Type of Rooflight

When it comes to rooflights, one size doesn’t fit all. The type of property you have and the style of your home impact the type of rooflight you need.

Many homeowners choose a style of rooflight based on cost and aesthetics. However, functionality is the most important component.

For example, a fixed rooflight will lead to problems in a room that needs to be ventilated, and a tubular rooflight won’t provide enough light for a large room.

Solution

  • Assess your home’s needs: Does the room need more light, ventilation, or both? Bathrooms benefit from a vented rooflight to prevent moisture accumulation.
  • Evaluate the roof’s structure: Ensure that your rooflight is compatible with the material and structure of your roof. Flat rooflights are suitable for flat or low-pitched roofs, while pitched rooflights are designed for steeper slopes.
  • Choose high-quality materials: If you’re looking for a permanent solution, choose materials that are built to last. This will prevent damage and the need for replacements down the line.

2. Incorrect Measurements

To ensure a smooth installation process, accurate measurements are vital.

Even the slightest error when measuring and cutting can lead to leaks and structural issues, putting your home at risk of damage.

Ignoring the roof pitch can lead to misalignment, as the angle of your roof affects the dimensions and positioning of your rooflight. Failing to account for beams, rafters, and other components can also cause you to cut into critical elements, leading to structural damage.

Solution

  • Use the right tools: Use measurement tools like a tape measure, laser measure, or level for accuracy when measuring.
  • Measure multiple times: Double-check all measurements numerous times to ensure precision.
  • Consider the roof pitch and structural elements: Always consider the angle of your roof and the placement of structural components. Use a pitch calculator to calculate the proper proportions and placement of your rooflight.

3. Ignoring Building Regulations

Building regulations are an important thing to consider when making any changes to your property.

Ignoring the rules and regulations for rooflight installations in the UK can lead to fines and legal issues. This can also lead to safety hazards, risking structural integrity, fire hazards, and inadequate ventilation.

Solution

  • Consult local authorities: Consult with your local planning office or council to familiarise yourself with the specific regulations and planning permission requirements for your area.
  • Hire professional installers: Hire a professional who is knowledgeable about building regulations to install your rooflights. They can also handle any paperwork required for building control approval.

4. Poor Placement of Rooflights

The placement of your rooflights plays a critical role in the performance, safety, and durability of the installation.

Poorly placed rooflights can lead to inadequate lighting, structural issues, and poor energy efficiency.

Common mistakes include placing rooflights in shaded areas or in an area that disrupts the design and functionality of your home.

Solution

  • Assess sunlight exposure: Assess what areas of your roof are exposed to the most sunlight throughout the day. Place them in the area with the most natural sunlight, unobstructed by buildings and trees.
  • Plan for glare and heat control: Install rooflights with built-in blinds, tints, or UV filters to avoid overheating. Alternatively, position rooflights in areas that receive indirect sunlight.
  • Harmonise with interior layout: Place your rooflights where they will enhance the natural light in key areas of the home. This includes living rooms, kitchens, and hallways, without clashing with the room’s design.

5. Inadequate Waterproofing

Waterproofing is an essential process of the installation method that is often forgotten.

Inadequate water-proofing can lead to leaks, mould and mildew growth, and costly repairs. Using low-quality materials can compromise the effectiveness of the seal, causing water damage.

Improper sealing, such as waterproof membranes or incorrectly installed sealants, can lead to gaps in the rooflight. Neglecting to install or improperly installing flashing can also result in water penetration.

Solution

  • Use high-quality materials: Use premium waterproofing materials for membranes, sealants, and flashing to provide durable and effective protection against water ingress.

  • Correct flashing installation: Ensure that step flashing for pitched roofs and continuous flashing for flat roofs are installed properly. This should overlap the roofing material to create a seamless barrier against water.

  • Apply sealants properly: Use weather-resistant sealants to create a watertight seal around the rooflight. Apply them evenly to ensure there are no gaps or bubbles that could allow water to penetrate the surface.

6. Overlooking Maintenance

Rooflights need to be regularly maintained to ensure they’re functioning correctly.

This helps to identify issues before they become more serious, saving you time and money on repairing significant damage. Many people neglect this task, leading to a build-up of debris that blocks natural light and hinders ventilation.

Without regular maintenance, the seals on your windows can deteriorate, leading to water ingress and energy inefficiency. For vented rooflights, a lack of maintenance can lead to malfunctions and jams.

Solution

  • Regular cleaning: Use a non-abrasive cleaner and a soft cloth to clean any dirt, debris, and bird droppings.

  • Check and replace seals: Inspect the seals for signs of wear, cracking, or gaps. Replace any damaged seals promptly to maintain a watertight seal.

  • Test mechanisms: Test the opening and closing mechanisms of vented rooflights regularly to ensure they are operating smoothly. Lubricate any moving parts as needed and address any malfunctions.
