- Cracked, blistered, or lifting felt

Garage Roof FAQs
Common questions about garage roof replacement and repair in North London
How do I know if I need a garage roof repair or replacement?
If your garage roof is relatively new and the damage is isolated, a targeted repair may be all that's needed. If it's older, showing widespread deterioration, or has suffered significant damage, a full garage roof replacement is likely to be more cost-effective in the long run. We'll give you an honest assessment during your free survey.
How much does a garage roof replacement cost?
The cost depends on the size of your garage, the materials chosen, and the extent of any existing damage. We provide free, no-obligation surveys and clear, itemised quotes so you know exactly what you're paying for before any work begins.
How long does a garage roof replacement take?
Most garage roof replacements can be completed within one to two days, depending on the size of the roof and the materials being used. We'll give you a clear timeline as part of your quote.
What is the best material for a garage roof?
This depends on your budget, the style of your property, and how long you want the roof to last. Fibreglass (GRP) is one of the most durable and low-maintenance options, with a lifespan of up to 40 years. Felt is a more traditional and cost-effective choice. We'll advise on the best option for your property during your free survey.
How long will a new garage roof last?
A well-installed garage roof using modern materials should last anywhere from 20 to 40 years depending on the material chosen. Fibreglass roofs in particular offer excellent longevity with minimal maintenance required.
Do you carry out garage roof repairs as well as replacements?
Yes. We carry out garage roof repairs of all sizes, from minor leaks and felt repairs to more extensive damage. We'll always advise honestly on whether a repair will suffice before recommending a full replacement.

Yes. We carry out garage roof replacement and repair services across North London and the surrounding areas including Pinner, Ruislip, Hendon, Hampstead, Finchley, Edgware, Northwood and beyond.
