The Project: Repairs to pitched roof in Welwyn Garden City

Our client contacted us after a heavy September storm. They were experiencing leaks in the hallway of their 1920s semi-detached property, and he had also noticed issues with the guttering, with water dripping between sections of the systems.

Our roofers attended the property quickly and diagnosed the issue. There were a number of dislodged tiles, causing the leak. In the long-term, this could cause further leaks and potential structural damage. We also noticed that the gutters were heavy and sagging, causing misalignment, meaning that the water was not running smoothly through them, leading to further water ingress issues.

We discussed the issues with the property owner and the best and most cost-effective repairs. They were happy for us to go ahead and complete the work, which we did immediately to ensure no further water damage.

The first step was to secure the property. We removed the damaged tiles to prevent further ingress and replaced them with high-quality replacements that closely matched the existing ones for a seamless appearance. Our team only use the best tried and tested products to ensure optimal outcomes.

We then cleared the gutters of debris and reinforced them with new brackets, ensuring they were correctly aligned to allow for efficient water flow.

The Results

The client was really happy with the work and relieved that the issues had been corrected. The roof was free from leaks, and rainwater flowed correctly away from the walls and into the drains.

They said: 'The team at Radlett Roofing were fantastic. They were highly professional and single-minded in getting the job done properly and efficiently. Their quote was competitive, and they were really helpful. They only replaced the materials that were not fit for purpose. I would highly recommend their roofers.

Any challenges?

The weather was dreadful, but our roofers continued to finish the job. Finding tiles that matched the old ones was tricky, but they succeeded in sourcing a close match.
