In addition to the roof size there are ather considerations to be mindful of when looking at the project, typically these are:

Environmental assessment - will we be close to a water source and do we need to consider run off of the treatment that is used?

Are electrical cables present that need to be avoided, we will manage the application of shouding if required.

Can we gain access all the way around the property?

Can we work safely?

How do we get access to your roof?
