Frequently Asked Questions
How long does a flat roof last?
With proper installation and maintenance, a flat roof can last anywhere from 20 to 40 years, depending on the material used. Single-ply membranes and GRP fibreglass typically offer longer lifespans, while felt roofing may need replacing sooner. Regular inspections and timely repairs can significantly extend the life of your flat roof.
Are flat roofs prone to leaking?
Flat roofs can be more susceptible to water pooling if not installed or maintained properly. However, modern flat roofing systems are designed with effective drainage and waterproofing in mind. Choosing high-quality materials and having the roof installed by experienced professionals greatly reduces the risk of leaks.
What is the best material for a flat roof?
The best material depends on your property and budget. Single-ply membranes are durable, flexible, and resistant to UV and weathering. GRP fibreglass offers a seamless, long-lasting finish, and felt roofing is a cost-effective solution ideal for smaller projects. We’ll recommend the best option based on your specific requirements.
