Premium Materials for Pitched and Flat Roofs

The longevity of a new roof is heavily dependent on the quality of the materials used. We only source industry-leading products designed to withstand the unpredictable UK weather. For pitched roofing, we regularly work with trusted brands like Marley and Redland, offering beautiful natural slate or durable concrete and clay tile installations.For flat roof replacements, such as garages or extensions, traditional felt is no longer your only option. We specialise in modern, highly durable alternatives. Our GRP (fibreglass) and EPDM (rubber) roofing systems offer seamless, waterproof finishes that flex with temperature changes, heavily reducing the risk of splits and leaks.Whether you require a traditional clay tile finish for a period property or a sleek EPDM system for a modern extension, we explain the benefits of each material so you can make the best choice for your home.

Navigating UK Building Regulations Safely

Replacing more than 25% of your roof requires compliance with Part L of the UK Building Regulations, which focuses on the conservation of fuel and power. This often means upgrading your roof's thermal insulation at the same time. Navigating this red tape can feel overwhelming for a homeowner.As trusted local experts, Kevington Roofing and Building LTD handles all local compliance and regulatory awareness on your behalf. We ensure that your new roof installation not only meets but exceeds current structural and thermal standards. If you reside in a conservation area within Dartford or the surrounding Kent villages, we also have the expertise to ensure materials match local authority planning requirements.

"Reliable and prompt - the Kevington team was able to view the property and provide options and transparent, itemised quotes on the same day I called. After deciding what level of work I wanted done, they returned soon after to carry out the roof repairs to a high standard without me even needing to be there."

Philip Day

"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.
