Featuring four sloping roof faces that meet neatly at the centre, this pergola delivers a balanced, pavilion-style look that instantly elevates patios, seating areas, and outdoor entertaining spaces.

FAQs – Open Roof 4 Pitch Wooden Pergola
Product
What is a 4 pitch pergola?
A 4 pitch pergola features a roof structure with four angled sides that slope upwards and meet at a single central point. This creates a balanced, pyramid-style shape that offers strong visual appeal and a more architectural finish.
How does a 4 pitch pergola differ from a standard apex pergola?
A standard apex pergola has two sloping roof faces that meet along a central ridge. A 4 pitch pergola, by contrast, slopes on all four sides and meets at the top, giving it a more symmetrical and pavilion-style appearance.
Is the timber treated for outdoor use?
Yes. All main structural components are pressure treated to protect against rot, moisture, and insect damage. Roofing elements may vary depending on the option selected.
Can this pergola be made to custom sizes?
Yes. Bespoke dimensions are available, allowing the pergola to be tailored precisely to your garden or patio space. Contact our team to discuss your requirements and receive a custom quotation.
Will I need planning permission for a 4 pitch pergola?
In most cases, pergolas can be installed under permitted development rights. However, rules can vary depending on property type and location, so checking with your local council is always recommended.
Installation
Does the pergola come pre-assembled?
No. The pergola is supplied in kit form for easier transport and access. Detailed installation instructions are provided to support both DIY installation and professional fitting.
Are fixings included with the kit?
Yes. All required fixings for assembling and securing the pergola are included as standard.
Will I need to cut any components during installation?
Yes. Some roof components are supplied oversized and will need cutting to size on-site. This allows greater flexibility and a more precise fit for your specific layout.
Aftercare & Maintenance
Can the pergola be painted or stained?
Yes. Once the timber has dried fully, you can apply a water-based paint, stain, or protective finish. Applying UV protection before painting is recommended to help preserve colour and timber quality.
What maintenance does the pergola require?
To maximise lifespan, we recommend treating the pergola every 6 months with a suitable wood oil and periodically cleaning off dirt and debris.
How long can I expect the pergola to last?
With correct installation and regular maintenance, a pressure-treated wooden pergola can typically last between 10 and 20 years, depending on exposure and care.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.
