We often get asked why we charge for a roof leak investigation but provide quotes for roofing works.

The key difference is this: A quote is provided when the scope of work is already clear.

For example, replacing a section of roof sheets, installing new guttering, or carrying out a roof restoration. In these cases, we can visually assess the works required and price them accordingly.

A leak investigation, however, is a diagnostic service.

When a roof is leaking, the source is often not obvious and is rarely where the water is appearing internally. Properly identifying the cause requires a detailed inspection, testing, checking flashings, penetrations, laps, drainage points and surrounding areas. In some cases, previous repairs may also need to be assessed.
During a leak investigation, we are:

• Diagnosing the root cause
• Using experience to trace water entry points
• Documenting findings with photos
• Providing a professional assessment
• Recommending the correct long-term solution

That process is a professional service in itself.

Without a proper investigation, any “free quote” would simply be guesswork — and guesswork leads to repeat leaks, unnecessary costs, and frustration.

By separating the investigation from the repair quote, we ensure:

• The problem is correctly identified
• The scope of works is accurate
• Clients only pay for what is actually required
• The solution is done properly the first time

In short, a quote prices known work.

An investigation determines what the work actually is.
