Why Roof Leak Detection is Important
Ignoring a roof leak can lead to damp, mould growth, rotten timbers, and even ceiling collapse. By detecting the problem early, we can carry out targeted repairs that save you money and protect your home’s integrity.
Our Roof Leak Detection Process
- Full Roof Inspection – We assess your roof’s condition, checking for cracked tiles, damaged flashing, loose ridge caps, or flat roof membrane issues.
- Water Ingress Tracing – We use proven methods to trace where water is entering your property.
- Moisture Mapping – For flat roofs, we can identify areas of trapped moisture beneath the surface.
- Repair Plan – Once the leak is located, we provide a transparent repair quotation.
Roof Types We Cover

When I returned home, I noticed a couple of minor gaps from inside the loft (which weren’t visible from outside). Isaiah came back and sorted them without delay.
Isaiah and his team worked quickly and professionally and Isaiah communicated well. I would highly recommend Lee Roofing as a trustworthy company.
Such a welcome joy to find Lee Roofing Service.
Isaiah came round promptly, was so helpful, took photos of the area concerned, explained so thoroughly the issues we were having and could face, by the photo evidence. A roof not an easy thing to see for yourself!
This led to an immediate trust building and he even helped immediately to resolve a problem giving us some "breathing" space before we venture to further works.
A genuine, good guy, a rarity but I found him.
Thank you
Isaiah and the team worked on my house just after I purchased it. They identified an issue causing water ingress, lifted the entire roof off the house to fix it and completed ancillary work around my chimney and gutters (all in 5 days!).They were complete professionals from start to finish and communicated clearly to us throughout the job. We knew exactly what was happening on each day and they did not go a penny over their initial quote. The team was also very friendly and polite. We particularly appreciated them tidying up at the end of each day!
I cannot recommend Isaiah and the Lee Roofing Services team highly enough - they were nothing short of brilliant.
