High-Quality Pitched and Flat Roofing Materials

Every property is unique, which is why we offer a comprehensive range of materials tailored to the local housing stock across Kent. For traditional pitched roofing, we work with premium natural slate, classic clay tiles, and highly durable concrete tiles from trusted manufacturers like Marley and Redland.If you are looking at flat roofs for an extension or garage, we provide advanced, seamless systems including GRP fibreglass and EPDM rubber roofing. These modern alternatives to traditional felt offer superior longevity and flexibility. Beneath the surface, we upgrade your home’s thermal efficiency and weather resistance using top-tier breathable membranes like Tyvek and Klober Permo Forte, alongside secure dry-ridge and dry-verge fixing systems to prevent future wind damage.

Frequently Asked Questions About New Roofs

How long does a new roof installation typically take?For an average semi-detached property in Swanley, a standard pitched roof replacement usually takes between a few days to a week, depending on weather conditions and the complexity of the design.Do I need planning permission for a roof replacement?In most cases, replacing a roof falls under permitted development. However, if you are significantly altering the roof height, living in a listed building, or residing in a strict conservation area in Sevenoaks, permission may be required. We assess this during your initial consultation.What is the difference between EPDM rubber and GRP fibreglass?Both are exceptional flat roofing solutions. EPDM rubber is installed as a single sheet, meaning there are no seams for water to penetrate, making it highly flexible. GRP fibreglass is brushed on as a liquid system that cures into a tough, rigid, and highly durable surface. We will recommend the best option based on your specific property.

"Highly recommended! Great price! First class job. Nothing was too much for these lads, very polite, got the job done and more. When they had finished they cleaned up that well, even took some of my own rubbish away for me. Well done lads! Not often you get a good, honest local roofer anymore! Thanks again."

Expert Roofing Advice

New Roof Installation FAQs

Considering a roof replacement? Here are answers to the most common questions we receive regarding our new pitched and flat roof installations for homeowners across Swanley, Sevenoaks, and Croydon & South London.

How much does a new roof installation cost in Swanley?

+

The cost depends on the size of your property and the materials you choose. A small terraced house using concrete tiles will cost less than a large detached home requiring natural slate. We provide free, detailed quotes that break down every cost, so you can make an informed decision based on your budget.

How long will it take to replace my roof?

+

Most domestic re-roofing projects take between one and two weeks, depending on the weather and the complexity of the roof shape. We work efficiently to make sure your home is "dried in" as quickly as possible to prevent any internal disruption.

Do I need planning permission for a new roof in Kent?

+

Generally, you do not need planning permission for a simple re-roofing project, provided the height of the roof does not change significantly. However, if you live in a conservation area or a listed building in places like Eynsford or Shoreham, special rules may apply. We can advise you on these requirements during our initial site visit.

Should I choose a pitched roof or a flat roof for my extension?

+

This usually comes down to your budget and the style of your house. Pitched roofs are incredibly durable and offer a classic look, while modern flat roofs using GRP (fibreglass) or EPDM (rubber) are excellent, cost-effective options for extensions and garages. We can talk you through the pros and cons of each during your consultation.
