Premium Pitched and Flat Roofing Solutions

Choosing the right materials is crucial for the longevity and character of your property. For pitched roofing, we expertly install traditional natural slate, classic clay, and durable concrete tiles from trusted leading brands like Marley and Redland.These traditional tiles are fitted alongside advanced breathable membranes, such as Tyvek or Klober Permo Forte, to prevent internal condensation and drastically improve your home's thermal efficiency. We also highly recommend upgrading to modern dry-ridge and dry-verge systems for a storm-proof, maintenance-free finish that eliminates the need for traditional mortar.If you are upgrading a flat roof on a rear extension, garage, or dormer window, we offer state-of-the-art EPDM rubber and GRP fibreglass roofing systems. Both of these modern options provide a seamless, highly durable, and watertight finish that far outlasts traditional felt alternatives.

How Our Roof Replacement Process Works

Replacing a roof is a significant investment, so we make the process as straightforward, transparent, and stress-free as possible from start to finish.Comprehensive Survey: We begin with a thorough structural assessment to identify hidden water ingress, failing timbers, or poor ventilation.Transparent Quotation: You receive a fully itemised, no-obligation quote. You will know exactly what materials we are using and what you are paying for, with no hidden surprises.Professional Installation: Our directly employed craftsmen safely erect scaffolding, strip away the old materials, and expertly install your new underlay, battens, and roof covering.Site Clearance: Once the final ridge tile and precision leadwork are perfectly in place, we clear the site entirely, leaving you with a flawless, weather-tight home.

The Benefits of a Complete Roof Replacement

Continually patching up an old, failing roof can often cost more in the long run than investing in a proper replacement. A brand-new roof provides immediate and long-lasting benefits for any homeowner.Complete Weather Protection: Secure your property against severe winter storms and prevent further internal water damage to your ceilings and decor.Improved Thermal Efficiency: Modern insulation and high-quality breathable membranes help to lock in heat, potentially lowering your winter energy bills.Enhanced Kerb Appeal: A fresh, professionally installed roof instantly boosts the visual appeal and overall market value of your property.Total Peace of Mind: With extensive warranties and no more anxiety over emergency leaks, you can relax knowing your home is structurally secure.

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.
