Roof Replacement London

Some clear signs include: multiple leaks, widespread cracked or missing tiles/slates, sagging roof boards, visible daylight through roof boards in the loft, recurrent patch-fixes that keep failing, aged materials beyond their lifespan (e.g. 20-30 years+ for many tiles/slates), or when the underlying structure (timber, battens, under-felt) is damaged. We always perform a survey to assess if replacement is more cost-effective in the long run than repeated repairs.

From start to finish, we:

• Carry out a complete roof survey, checking structure, coverings, flashing, insulation, etc.
• Remove the old roofing material, including any damaged framework or underlay.
• Replace or repair roof structure where needed (e.g. rotten timbers).
• Install new underlay, battens, and fixings as required.
• Fit new roofing material (tiles, slate, flat membrane, etc.) chosen by you.
• Replace or repair ancillary parts — flashings, ridge tiles, gutters/downpipes, moss protection, etc.
• Ensure correct insulation and waterproofing, finish and clean, and provide any guarantees.

It depends on the size, type (flat roof vs. pitched; simple slope vs. multiple hips/valleys), materials, access, scaffolding requirements, and whether the structure is sound or in need of repair. For a typical pitched roof on a mid-sized home, replacement could take a few days. More complex or larger roofs may take a week or more. We ensure that you receive a clear timeline once the survey is complete.

Costs vary widely depending on: roof size and pitch; materials (tiles vs. slate vs. membrane vs. high-end materials); the amount of structural work required; access and scaffolding; removal and disposal of old materials; insulation; flashings, etc.; location & local labour rates. As a rough guide, full roof replacement in London can range from £5,000 to £12,000+ for many standard homes, up to significantly more for large, complicated, or heritage properties.

We offer a range of products, including clay tiles, concrete tiles, natural slate, single-ply membranes, flat roof membranes (such as EPDM, felt, and torch-on), lead flashings, and more. Factors to consider when choosing a material include: the style of your property (aesthetic match), durability, maintenance requirements, cost, weight (especially for slate), insulation or thermal efficiency, and local planning/building regulations. We will help you with pros & cons to make the right choice for your needs and budget.

Usually, replacing with like-for-like materials doesn't need planning permission. However, if you are changing roof pitch, adding dormers or skylights, altering the height or shape, or if you are in a conservation area / listed building, you may need permissions. All replacement work must comply with the Building Regulations (e.g., for insulation, waterproofing, and structural work). Environ Roofing will advise you on what's required and handle compliance where needed.

Yes, very likely. When replacing a roof, we can install newer insulation and ensure better air tightness, improved ventilation, and more efficient materials. This reduces heat loss, which helps in winter months, and can make cooling easier in summer. So the investment can pay off over the medium to long term in savings on heating/cooling.

We stand behind our work. Our roof replacement services include workmanship guarantees and, where applicable, manufacturer warranties on the materials used. We will specify what components are covered (tiles/slates/membrane, flashings, insulation, etc.), for how many years, and any conditions (maintenance, periodic checks, etc.), so you have confidence in the lifespan of your new roof.

Some disruption is unavoidable (noise, scaffold, removal of old materials, access). But we plan carefully to minimise it: we'll let you know the schedule, protect your home (cover furniture etc.), limit dust and debris, organise safe access, clean up daily, and communicate clearly. We aim for a smooth process so you are not unexpectedly inconvenienced.

We combine knowledge, extensive roofing experience, quality materials, and customer care. We understand London's weather, building types, design requirements, and regulations. Our process is transparent (survey → quote → schedule), our workmanship is solid, and we aim to deliver your replacement roof on time, on budget, and with minimal stress. Additionally, many satisfied homeowners have trusted us with their London projects and can vouch for our service.
