How to Order
Order the TruMAX roof system with ease, through this website. To simplify the process, we have broken-down the key decisions, and provided explanation of each option. Every order is reviewed by our team, and confirm back to you prior to manufacture, to ensure that you get the roof you want.
-
Width & Projection
Enter the roof width into the ‘Width (mm)’ field, and the projection into the ‘Projection (mm)’ field.
If fitting to existing 70mm frames, Width is measured from inside face on one side, to inside face on the other. Whilst Projection is measured horizontally (not down the slope) from host wall to inside face of front frame. See our Surveying Guide for more. -
Pitch
Enter the angle of the roof into the ‘Pitch’ field. Pitch can be between 5° and 15°, or from 2.5° for low-profile roof.
Pitch can be calculated by dividing the vertical Rise of the roof (from front support to top of slope), by the Projection, and running that through an arctan function on your calculator. You can also use our Roof Pitch Calculator below, or give us a call. -
Glazing
Select a glass type that meets your performance needs, or choose ‘Unglazed’ if sourcing separately.
The range of options is broad to help you receive glass that best fits your needs. Key considerations are overall u-Value, Solar Heat Reflection, and Light transmission.
For help understanding the options, see Things to Ask Yourself. -
Additional Options
We offer a variety of additional options to help you tailor a roof to your exact needs.
- Frame Colour (inside/outside)
- Eaves Support Posts
- Starter Bar
- Gutter Colour
- Downpipe Position
More details about the Addditional Options can be seen below.
Things to Ask Yourself
Roof Pitch Calculator
Enter your Projection and Rise measurements, then click 'Get Pitch'. Simple!
Notes:
Projection is measured horizontally from host wall to inside face of front frames, if going on top of existing 70mm frames. Otherwise projection would be from host wall to external face of front support, minus 70mm.
Rise is a vertical measurement from top of front supporting frame to top of slope at host wall.
Take a look at the following Technical Information, and our Surveying Guide, to better understand site considerations. See the FAQ at the bottom of the page for answers to common questions.

Delivering Your Roof
We are able to deliver polycarbonate and glass roof systems to most mainland postcodes, but quieter and more rural destinations may have a longer time in transit. Expected delivery date shall be advised in our order confirmation back to you.
-
Receiving Delivery
- Drivers will help offload from the vehicle, but the recipient is responsible thereon.
- At least one person is required to receive delivery. We recommend two able-bodied people for larger roofs, and those with glass units, .
- Aluminium and PVC-u extrusions may be wrapped together for protection during transit.
- Pads or shrink-wrapping may be applied to protect glass units and roof sheets.
- Check carefully to ensure you have expected components, and that they match your order.
- We handle with care, but edges and corners are vulnerable. Check for damage, and inform the driver if you spot any flaws.
- A redelivery cost may be charge if unable to receive delivery on agreed day.
-
Storing and Handling
- Glass handling gloves should be worn to reduce the likelihood of cuts, and slippage.
- Leave any pad or shrink-wrap protection in place until installation.
- Store in a clean, dry, ventilated space, away from direct sunlight and heat sources.
- Do not lay glass horizontally. Stand on edge between 3° and 6° from vertical.
- Prevent bowing by ensuring that the back of glass and polycarbonate sheets are well supported.
- To avoid staining, separate and dry thoroughly if moisture is spotted between stacked units.
- Polycarbonate sheet are lightweight, but double-glazed units weight between 20 and 30 kg per square metre. Take great care when handling roofing materials and glazing.
FAQs
What is Light Transmission and is it important?
What is Shading Coefficient?
Shading Coefficient (SC) measures how much solar heat can transmits through the roof glazing. The higher the figure, the more heat is allowed to pass through.
High Shading Coefficient glazing helps to warm a room naturally in cooler months (reducing energy bills), and allows more natural light. However, rooms can become uncomfortably hot, requiring the use of fans, air conditioning, or blinds, and the increased UV rays can fade furniture. North-facing and shaded roofs might benefit from high shading coefficient glazing.
Low Shading Coefficient glazing reduces overheating in the summer, reduces reliance on fans etc., and helps protect interiors from UV damage. However, rooms may receive less natural light, and require more heating during colder months. South-facing roofs will likely benefit from low shading coefficient glazing.
Does a lean-to need planning permission?
Conservatories smaller than 30m2 don't normally require Planning Permission. However they must comply with IEE and Building Regulations.
