New for Old

Upgrading your roof is one of the most effective ways to improve the energy efficiency of your building, and to deal with issues such as poor drainage.


Refurbishment offers all kinds of opportunities to get creative. As well as looking at insulation, you could consider changing a flat roof to a pitched one, or making use of the space it offers to install solar panels and generate energy to reduce your bills.

Get active

Using your roof space is a great way to protect and enhance the environment, or help to manage weather events, such as excessive heat or rainfall.


Green roofs are a well-established way to support biodiversity, or even create a garden where people can relax and enjoy a natural environment in the middle of the city.


Blue roofs offer effective water management to help prevent flash flooding or drainage problems, and cool roofs use reflective technologies to keep internal spaces from over-heating.
