How to Measure Your Roof
Measuring your roof for a green roof is simple with the right information. If you have architectural drawings or build plans, start there—they’ll give you accurate dimensions without needing to access the roof. If not, you can measure manually using a tape measure, measuring wheel, or, for larger commercial roofs, a laser measurer.
Be sure to measure the usable roof area:
Measure inside any parapets or upstands.
Deduct the space taken up by rooflights, vents, chimneys, and other obstacles.
If you plan to include pebble borders or firebreaks, subtract these from the total green roof area as well.
Remember to convert any measurements in feet to metres, as our products are sold in m². We also recommend adding 5–10% extra to your order to allow for cutting around roof features and ensuring full coverage.
If you’d like help confirming your measurements, our team is always happy to assist.
Delivery Information
Typical lead times are around three days, though this can vary seasonally—contact us if you’d like an up-to-date lead time or to arrange a specific delivery date.
As brown trays contain no vegetation, they can be sent using our economy service, which is cheaper and usually arrives within 1–3 days.
If your order includes both brown and sedum trays, the full shipment must go via next-day delivery to protect the live plants.
Deliveries are made through the national pallet network, with arrival expected between 9am and 4:30pm, and someone must be on site to receive the order.
The trays arrive stacked on wooden pallets and are offloaded using a tail lift.
Unlike sedum trays, brown trays do not need to be unstacked on the day they arrive, giving you more flexibility.
Collecting your order:
Prefer to collect your order yourself? No problem. If you’re a tradesperson arriving in a truck, transit or van, we can stack, strap and load your trays directly onto your vehicle using our forklift, or handball them on if you’d prefer. For smaller orders collected in a day-to-day car, we recommend folding down the seats to maximise space and laying a waterproof sheet or tarpaulin in the boot, as the sedum trays can release water in transit. Because we’re not always on site and each order needs preparing in advance, it’s essential that you book your collection slot—please contact us at least a couple of days before you plan to arrive so we can have everything ready for you. We generally accept collections from 9am-4pm, Monday to Friday
