Roof Inspection Services - Expert Roofing Solutions

Maintenance Survey & Report

Protect your investment with our expert flat and pitched roof maintenance surveys. Our comprehensive report details all maintenance needs including a maintenance schedule, giving you a clear timeline for future planning. For a more thorough assessment, we offer an expanded survey that includes specialised services such as lightning conductor testing, Photovoltaic Testing and CCTV drainage analysis. We are committed to accommodating your unique needs with a service tailored just for you. For hard to access roofs we can also use drone and telescopic pole technology to provide a comprehensive inspection.

Condition Survey & Report – Flat Roofs

 Our comprehensive flat roof condition surveys employ an in depth approach to accurately diagnose the integrity of your roofing system. The process involves an internal examination supported by core sampling to determine the roof's structural deck and condition within the insulation zone. An endoscope can also be used to determine complex build ups. We will also collate all the relevant information and advise on drainage  in accordance with BS EN 12056:3-2000 . There are other methods of non-invasive techniques we provide, including moisture mapping and infrared thermography, as well as leak detection analysis. 

Drone Condition Survey & Report - Pitched Roofs / Metal Roofs

Our professional drone roof surveys offer a non-invasive solution for inspecting roofs and hard-to-reach areas, significantly enhancing safety and efficiency compared to traditional methods. Our experienced surveyors interpret the high-resolution imagery and data captured by the drones to produce a comprehensive report. This report details the roof’s condition and its compliance with current building regulations, with the scope and depth customised based on your specific brief. In areas where a drone is not suitable to fly, we can use telescopic pole technology to aid with the survey.

 Given that asbestos was widely used in construction until its ban in 1999, many older buildings still contain asbestos in their roofing materials. We are specialists in providing comprehensive access and testing services for both flat and pitched roofs. After a thorough assessment, we will outline your options, advise on the best remedial strategy, and provide a guidance on costs for safe asbestos removal and replacement with a new roofing system, that meets current building regulations and inline with HSE guidance.
