Frequently Asked Questions

Find answers to common questions about our roofing services.

How do I know if my roof needs repairing or replacing?

Common signs include recurring leaks, damp patches on ceilings or walls, loose or missing tiles, blistering on flat roofs, and overflowing guttering. During an inspection, we assess whether a repair will solve the issue long-term or whether replacement is the safer and more cost-effective option.

Yes. We provide free, no-obligation inspections and clear quotations. You will be given honest advice on the condition of your roof and a breakdown of recommended work, with no pressure to proceed.
We handle everything from minor repairs to full roof replacements. If a small repair is all that is needed, we will not recommend unnecessary work.
We work on flat and pitched roofs for domestic and commercial properties, including felt roofing, GRP fibreglass, tiled roofs, rooflines, skylights, and associated roofing systems.
Timeframes depend on the type and size of the job. Small repairs may be completed in a few hours, while larger projects such as full roof replacements typically take several days. Clear timescales are provided before work begins.
Disruption is kept to a minimum. We work efficiently, maintain a tidy site, and communicate clearly throughout the job so you know what to expect at each stage.
Yes. All work is carried out by fully insured professionals, giving you peace of mind that your property is protected throughout the project.
