1a. Thermographic Surveys
This form of non-destructive electronic testing uses award-winning, state-of-the-art infra red camera technology and can be utilised on existing or new build projects. It can quickly and precisely visually pinpoint areas of moisture damage or inadequate insulation. This form of predictive maintenance detection enables Under 1 to provide a cost-effective, targeted repair solution rather than full replacement.

In the case of existing roofs, an Under 1 Thermographic Survey can detect the deterioration and subsequent breaching of exposed waterproof membranes due to UV damage. It accurately highlights areas where water has penetrated, is trapped and causing moisture damage.

For refurbishment and new build projects, an infra-red Thermographic Survey can clearly expose where insulation is missing, water is trapped or cold bridges exist.

We offer this as a separate chargeable service or it can be included as part of a full roofing project.

1b. Moisture Gauge
The main use for our Moisture Gauge is to detect moisture in a roofing system without causing any physical damage to the system. The device measures moisture through the presence of a source called Americium Beryllium. The source is sealed into the device and omits gamma rays which thermalise hydrogen neutrons (present in the rainwater within the system) and a reading is returned to the device. The reading is not given in any particular unit, but is merely a figure. The figures often change due to the different waterproofing build-ups, however as experienced users we can determine which figures indicate dry areas and which figures indicate water ingress.

The results are recorded by marking a grid on the roof, typically with 1-2m spacing, depending on the overall area of the roof. Systematic readings are then taken at points such as A1, C10 etc and are put into a table. The roof and its results are then illustrated in a chart for ease of reading for the client. This grid system allows us to ascertain how widespread the leak is, and also the source of the ingress.

Overall the device allows Under1 to save the client unnecessary costs by isolating the affected areas. It is also a useful tool for us as it often highlights defective areas/detailing that would be very difficult to see just from our visual surveys.






2. Condition Surveys
Under 1 are renowned within the industry for producing some of the most highly comprehensive and honest reports for all types of roofs. Each report clearly identifies the problems concerning the roof and the correct waterproofing solutions, if any.

We work quickly yet thoroughly to produce our surveys in order to report any problems ASAP and to stop any problems worsening.

Estimated budget costs for remedial or refurbishment works can also be provided at this stage.



3. Specifications
Once we have ascertained precisely what waterproofing solution is required, we can provide detailed specifications for existing or new buildings.

Under 1 Roofing Consultants specifications can be designed for inclusion into tender documents. Our extensive knowledge of the roofing market allows us to put forward the most suitable system considering your budgets, etc.

We attend product launches, industry exhibitions, regularly researching new products etc which puts us in a position to recommend products that are not covered by your typical local manufacturers’ salesman.

Our advice is backed by Full Professional Indemnity Insurance.



4. Waterproofing Systems
Because we are 100% independent, we have no tie-in with or obligation to use any particular manufacturers.

This freedom puts us in the unique position of being able to work with the tightest of budget constraints, highest guarantees and specialist systems within the roofing industry.

The result: you receive the most cost-effective and effective solution.



5. Contractors
We have constructed a comprehensive and impressive list of approved contractors that have to complete a detailed questionnaire about their company.

Under 1 pre-vets them on your behalf, diligently looking into their company history and membership to professional bodies, etc. If they don’t check out, they don’t make the Under 1 list.

Any number of contractors can be provided for your tender purposes should you have a local contractor then they can be included provided we are all happy with their credentials.



6. Project Management
Under 1’s involvement in roofing projects can extend far beyond that of many others in the roofing industry.

As experienced project managers, we carry out pre-start meetings and regular progress meetings with the contractor and conduct on-going site inspections.

All meetings are carefully documented and reported direct to you, the client. This means you are constantly kept informed and updated.

We will monitor all aspects of the roofing works to ensure a high quality of installation is maintained and all the roofing works comply with the specification.
