Traditional Roofing Expertise for London's Period Properties

Traditional London roofs require more than a quick patch.

Natural slate, leadwork, chimneys, valleys, ridges, hips, mortar and flashing details all work together to keep a property weatherproof. On older properties, inappropriate repairs can create further problems or detract from the character of the building.

NSG Roofers specialise in the types of roofing found on Georgian, Victorian, Edwardian, period and heritage properties throughout North West London.

We assess the visible problem, investigate the likely cause and recommend the most appropriate repair wherever practical.

Our approach is simple: repair what needs repairing rather than automatically recommending a complete new roof.

Our Roofing Services

Slate Roof Repairs

Broken, cracked, slipped or missing slates can allow water into the roof structure and surrounding areas.

We carry out individual slate replacements and localised slate roof repairs, while also checking surrounding areas for related defects that may have contributed to the problem.

Fixed-Price Slate Repair From £599

For suitable repair work, our fixed-price slate repair service provides a straightforward starting price for homeowners dealing with isolated slate damage.

The service is intended for qualifying repairs where the scope can be established without major additional works.

Before proceeding, we will confirm whether your roof appears suitable and explain what is included, together with any relevant access requirements or circumstances that could affect the final scope.

Leadwork & Flashing Repairs

Leadwork is critical to keeping vulnerable areas of a traditional roof watertight.

We repair and renew leadwork including:

Chimney flashings

Apron and stepped flashings

Lead valleys

Abutment flashings

Box and secret gutters

Dormer leadwork

Parapet details

Roof penetrations

Where possible, we identify why the leadwork has failed rather than simply covering the visible symptom.

Our chimney repair work can include:

Chimney repointing

Flashing repairs

Mortar repairs

Chimney-pot capping

Localised masonry repairs

Weathering and water-ingress issues

We assess the condition of the chimney and recommend work appropriate to the defect.

Ridge & Hip Repairs

Loose, cracked or deteriorated ridge and hip details can become a source of leaks and, in some circumstances, a safety concern.

We repair or renew defective ridge and hip tiles, slates, mortar and associated fixings where required.

We explain the proposed work, price basis and relevant access requirements before work begins.

Common Roofing Problems We Repair

If you've noticed any of the following, contact NSG Roofers for advice:

Missing roof slates

Slipped slates

Cracked or damaged slates

Water entering the loft

Damp patches or water staining

Leaking valleys

Failed chimney flashing

Deteriorated chimney pointing

Damaged leadwork

Loose ridge tiles

Damaged hip tiles

Storm-related roof damage

Recurring roof leaks

Previous repairs that have failed

A visible leak does not necessarily indicate where water is entering the roof.

Rainwater can travel through roof coverings, timbers, membranes and masonry before appearing inside the property. For that reason, some problems require inspection before the correct repair can be identified.

Frequently Asked Questions

How much does slate roof repair cost?

Our fixed-price slate repair service starts from £599 for qualifying repairs. The actual cost depends on the condition of the roof, the work required and access.

Can you replace just one broken slate?

Yes. Individual slate replacement is one of the common localised repairs we undertake. We will also consider whether there is an underlying reason why the slate has failed.

Do you repair lead valleys?

Yes. We can assess and repair lead valleys and associated roof details where accessible and appropriate.

Do you repair chimney flashing?

Yes. Chimney flashing is one of the traditional roofing details we specialise in, and we can assess defective flashing and associated water-ingress problems.

Do you repair roofs on Victorian and Edwardian houses?

Yes. Our services are particularly suited to traditional roofing found on Victorian, Edwardian, period and heritage properties.

Do I need a new roof?

Not necessarily.

Where the roof structure and covering remain generally sound, localised repairs may be a more appropriate solution than complete replacement. We assess the condition of the roof and recommend the work that appears proportionate to the problem.

Do you offer emergency or same-day roof repairs?

Priority same-day and next-day appointments may be available depending on location, the nature of the repair and our schedule.

What areas do you cover?

We primarily serve North West London, including Hampstead, Highgate, St John's Wood, Hampstead Garden Suburb, Golders Green, Finchley, Mill Hill, Barnet, West Hampstead, Belsize Park, South Hampstead, Swiss Cottage, Primrose Hill and Kentish Town.
