FAQs – Wooden Lean-To Gazebo with Katepal Grey Shingle Roof
Product
What is a lean-to gazebo?
A lean-to gazebo is a structure designed to be fixed directly against an existing wall. It uses the building for support on one side, with posts at the front, making it ideal for patios and space-efficient garden layouts.
What’s the difference between a pergola and a lean-to?
A lean-to is attached to a building, while a pergola is usually free-standing and supported by four posts within the garden.
Is the Katepal grey shingle lean-to weather resistant?
Yes. When installed with a suitable waterproof membrane and maintained regularly with a quality wood treatment such as Osmo Oil, the lean-to offers reliable protection from the elements.
What are Katepal shingles made from?
Katepal shingles are made from SBS-modified bitumen, giving them excellent flexibility, durability, and resistance to tearing in varying weather conditions.
Are the timber components pressure treated?
Yes. All structural timber components are fully pressure treated to protect against rot, moisture, and insect damage. Roofing components may vary depending on the option selected.
Do I need planning permission for a lean-to gazebo?
In many cases, lean-to gazebos fall under permitted development and do not require planning permission. Regulations can vary, so it’s always best to check with your local council before installation.
Installation
Does the lean-to arrive fully assembled?
No. The lean-to is supplied in kit form for easier delivery and handling. Detailed installation instructions are provided to guide both DIY installers and professional fitters.
Are fixings included with the lean-to?
Yes. All fixings required for assembly and installation are included with your order.
Aftercare & Maintenance
Can I paint the lean-to gazebo?
Yes. Once the timber is fully dry, you can apply a water-based paint or finish. We recommend applying a UV-protective treatment beforehand to help preserve the timber’s appearance.
What maintenance is recommended?
To maintain performance and longevity, treat the timber approximately every six months with a suitable wood oil and regularly remove any built-up dirt or debris.
How long will the lean-to gazebo last?
With correct installation and regular maintenance, a pressure-treated lean-to gazebo 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.

Right product, right price, right delivery. Sure, it was only one length of cast iron guttering but they took the order seriously, packed it well and kept me updated on delivery. And when I opened the very good packaging I found it was exactly what I had wanted. How can you do better!!
