Reliable roof drainage with a high-quality box gutter

When it comes to protecting small roofs on carports, garden sheds or balconies from rainwater damage, a robust box gutter is the ideal solution. These square-shaped drainage systems effectively collect rainwater and channel it away safely, preventing structural damage to your property.

Thanks to their compact and angular design, box gutters fit seamlessly into modern architectural styles while offering excellent water flow capacity for smaller roof areas.

Our comprehensive box gutter assortment and accessories

In our shop, you will find a wide range of box gutter components manufactured by INEFA, ensuring a perfectly matched system. The core of the assortment consists of 200 cm long PVC box gutters, available in various nominal widths including NW 68, NW 83 and NW 115.

To complete your drainage system, we offer all necessary accessories. This includes standard and adjustable fascia brackets, drop ends, stop ends for left and right sides, connectors, and angles for both inner and outer corners. You can choose from attractive colours such as grey, brown, dark brown, white and anthracite to match your building's exterior.

How to choose the right box gutter for your project

Selecting the correct size is crucial for efficient water management. For small garden sheds or balconies, a nominal width of NW 68 is usually sufficient, whereas larger carports or canopies may require NW 83 or NW 115 to handle heavier rainfall. Ensure you select the matching brackets, drop ends and special PVC adhesive for a secure, watertight bond.

Depending on the specific component and package size, prices for our box gutter range from approximately £5.99 to £165.99 (as of 2026). Whether you need a single fascia bracket or a bulk pack of 20 pieces for a larger installation, you will find exactly what you need for your project.

Frequently Asked Questions about box gutters

How do I install a PVC box gutter correctly?

Installation is straightforward: first, mount the fascia brackets with a slight slope towards the drop end. Then, cut the gutter to the desired length, apply the special PVC adhesive to the connectors and fittings, and securely join the components together.

What is the advantage of a box gutter compared to a half-round gutter?

Box gutters offer a modern, angular aesthetic that sits flush against fascias, making them particularly popular for carports, conservatories and garden sheds. Additionally, their flat bottom can provide a high flow rate even in restricted spaces.

How often should I clean my roof drainage system?

It is recommended to inspect and clean your drainage system at least twice a year, ideally in spring and late autumn. Removing leaves, moss and debris ensures unobstructed water flow and prevents blockages or overflowing.

Can I cut the PVC gutter elements to size myself?

Yes, PVC-U components are very easy to work with and can be cut to the exact required length using a fine-toothed hand saw. Make sure to deburr the cut edges before applying adhesive to ensure a perfectly watertight seal.
