About us
What we do
We provide roofing surveys and diagnostic testing to help clients and contractors investigate roof issues.
Our services include Electronic Leak Detection, Moisture Mapping, Drone Surveys and Thermal Imaging Roof Surveys.

Our background
With over 20 years of experience in the roofing industry, we bring knowledge of contracts management, estimating and commercial management to our survey work. This gives us a practical understanding of roofing projects and the decisions involved in investigating and addressing roof issues.
We work with contractors, surveyors, manufacturers and property managers who need clearer information about a roof’s condition. Our testing can be used to check new roof coverings or investigate suspected leaks in existing flat roofs, helping you understand any defects found and consider the next steps.
Our Core Values
Our values guide how we approach every survey, from choosing a suitable testing method to presenting findings clearly. They reflect our aim to provide useful information that helps clients and contractors understand roof issues and decide on appropriate next steps.
