Emergency Roof Repairs in Hendon (24/7 Response)
When a roof leak strikes during a storm or you discover water dripping through your ceiling, you need a roofer who responds fast. Smart Roofing London offers 24-hour emergency call-outs across Hendon and NW4 for urgent roof repairs, storm damage, and weather-related issues.
London’s wet winters—with November being the wettest month and average annual rainfall around 690 mm—put pressure on aging roofs and flat roof systems. Named storms like Storm Éowyn in January 2025 caused significant wind damage across the capital, lifting tiles, damaging flat roofs, and exposing properties to water ingress. Hailstorms in spring also create unexpected damage that requires immediate attention.
Our emergency roofing services include temporary weatherproofing to prevent further water damage, replacing missing or slipped tiles, repairing flat roof leaks, and repairing damaged flashing or valleys. We understand that ceiling bowing, damp patches, and active drips can’t wait until Monday morning.
Until we arrive, move valuables away from the leak, place containers to catch water, and avoid touching electrical fixtures near wet areas. Our team will assess the damage, provide temporary protection, and give you a clear plan for permanent repairs.
New Roof Installation & Replacement in Hendon
Whether you’re replacing an aging roof on a 1930s home or installing a new roof on an extension, Smart Roofing London delivers high-quality pitched and flat roofing solutions designed for longevity, weather resistance, and energy efficiency.
When Does Your Hendon Roof Need Replacement?
Roof replacement becomes necessary when structural surveys flag damp timbers and inadequate ventilation, when tiles or slates are beyond repair (typically after 60-100 years depending on material), following severe storm damage, or when multiple leaks indicate widespread failure. Many Hendon homeowners contact us after receiving Level 3 surveys highlighting roof concerns during property purchases.
Pitched Roof Installation for 1930s Hendon Homes
Hendon’s Art Deco and pre-war properties feature traditional pitched roofs with clay, concrete, or natural slate tiles. We specialise in replacing these roofs while preserving the character of period homes in areas like Shirehall Estate and Sunny Hill.
Material options include:
- Natural slate: 60-100+ year lifespan, premium appearance, excellent weather resistance
- Clay tiles: 50-100 year lifespan, traditional aesthetic, ideal for conservation areas
- Concrete tiles: 40-60 year lifespan, cost-effective, wide range of colours and profiles
We ensure proper installation of underfelt or a breathable membrane, adequate ventilation to prevent condensation, and compliance with Barnet Council design guidelines that encourage pitched roofs to match existing structures.
Flat Roof Installation & Replacement
Modern extensions, garages, and apartment blocks across West Hendon and Colindale often feature flat roofing systems. We install and replace felt roofing and GRP (fibreglass) flat roofs with proper falls to ensure proper drainage and prevent water pooling.
Flat roof systems:
- GRP/Fibreglass roofs: 30-50 year lifespan, seamless waterproof finish, low maintenance
- High-performance felt systems: 20-30 year lifespan, cost-effective, suitable for most applications
Poorly installed flat roofs cause ceiling bowing and persistent leaks during heavy rain. Our installations include proper drainage, high-quality materials, and guarantees for peace of mind.
Roof Repair Services in Hendon (Pitched & Flat)
Not every roof problem requires a full replacement. Smart Roofing London provides cost-effective roof repairs across Hendon for slate, tile, and flat roofing systems—helping you protect your property without unnecessary expense.
Common Roof Repairs We Handle
Pitched roof repairs include replacing slipped or broken tiles and slates; repairing damaged roof valleys where two roof slopes meet; fixing or replacing lead flashing around chimneys and walls; replacing deteriorated or missing underfelt; and repairing storm-damaged battens or timber work.
Flat roof repairs address water pooling and drainage issues, patch felt roof leaks and blisters, repair damaged GRP fibreglass surfaces, replace failed edge trims and flashings, and fix leaks around skylights or roof penetrations.
Repair vs. Replace: Honest Advice
Many homeowners worry when surveys flag issues on 100-year-old roofs, but age alone doesn’t mean replacement is necessary. If your roof isn’t leaking, the structure is sound, and the tiles are intact, repairs or maintenance may be all you need. We’ll always tell you honestly whether repair or replacement makes sense for your situation and budget.
However, if you’re experiencing multiple leaks across different areas, if battens and timbers show significant rot, or if more than 30-40% of tiles need replacement, a full roof replacement is often more cost-effective in the long term.

Guttering, Fascias & Soffits in Hendon
Properly functioning guttering, fascias, and soffits protect your Hendon property from water damage, damp, and structural issues. Smart Roofing London installs, repairs, and replaces complete roofline systems in UPVC (white or black finishes) and traditional materials.
Why Guttering Matters
London’s rainfall—particularly during wet autumn and winter months—puts significant demands on your guttering system. Blocked, damaged, or inadequate gutters cause water to overflow, leading to damp penetration, fascia and soffit rot, foundation issues from poor drainage, and staining on external walls.
Our Guttering Services
We provide gutter installation for new builds and replacements; gutter repairs for leaks, sagging sections, and damaged joints; gutter replacement when systems are beyond repair or incorrectly sized; fascia and soffit installation in durable UPVC or timber; and fascia and soffit repairs and replacement to protect roofline integrity.
UPVC fascias and soffits offer excellent weather resistance, require minimal maintenance (no painting needed), resist rot and insect damage, and provide a clean, professional appearance in white or black finishes.
Regular gutter maintenance prevents expensive repairs. We recommend annual inspections and cleaning, particularly before winter, to ensure your system handles London’s wet weather effectively.

Chimney Repairs, Repointing & Leadwork in Hendon
Hendon’s 1930s and pre-war homes feature prominent chimney stacks that require specialist maintenance to prevent leaks, structural damage, and weather deterioration. Smart Roofing London provides comprehensive chimney repairs, repointing, and leadwork across NW4.
Common Chimney Issues in Period Properties
Chimney problems include deteriorating mortar joints requiring repointing to prevent water ingress and brick damage; failed lead flashing around the chimney base causing roof leaks; cracked or loose chimney pots creating safety hazards; spalled brickwork from frost damage and water penetration; and structural movement requiring stabilisation.
Our Chimney Services
We offer chimney stack repointing using appropriate mortar mixes for period properties; lead flashing installation and repair for weatherproof chimney-to-roof junctions; chimney stack repairs, including brick replacement and structural stabilisation; chimney pot repairs and replacement; and full weatherproofing to protect against London’s wet climate.
Quality leadwork is essential for preventing roof leaks around chimneys, valleys, and roof details. Our experienced team works with traditional lead materials to ensure long-lasting, weather-resistant installations that complement your property’s character.

Smart Roofing London installs, repairs, and replaces skylights on pitched and flat roofs across Hendon, delivering leak-free, professionally finished results.
Benefits of Skylights in Hendon Homes
Skylights provide abundant natural light, reducing electricity costs, improving ventilation, helping prevent dampness and condensation, increasing property value and appeal, and complying with building regulations for loft conversions that require adequate natural light.

Roofing Specialists for 1930s Hendon Homes
If you own a 1930s Art Deco semi or terraced house in Hendon, you may be concerned about your roof’s age, the lack of modern membranes, or survey reports highlighting “inadequate ventilation” and “damp timbers.” Smart Roofing London specialises in roofing for period properties and understands the unique characteristics of pre-war construction.
Understanding 1930s Roof Construction
Many Hendon homes were built without breathable membranes or underfelt—this was standard practice and doesn’t automatically mean your roof is dangerous or failing. These roofs relied on proper ventilation and tile overlap for weather protection. Condensation in roof spaces can cause damp staining that may look concerning but doesn’t always indicate structural problems.
However, after 90-100 years, roof timbers, battens, and tiles do eventually deteriorate. Survey reports flagging these issues deserve professional assessment, not panic.
When to Act on Survey Concerns
You should consider roof work if you have active leaks or water ingress; battens show significant rot that compromises tile support; multiple tiles are cracked, slipped, or missing; or structural timbers show serious decay that affects roof integrity.
You may not need immediate work if there are no leaks despite cosmetic damp staining, the roof structure remains sound with intact battens, tiles are secure and properly overlapping, or ventilation improvements alone can address condensation issues.
We provide honest assessments—if your 100-year-old roof is still performing well, we’ll tell you. If replacement is needed, we’ll match the original materials and respect your property’s character while incorporating modern improvements, such as breathable membranes, to enhance performance.

FAQ's
1. How much does roof repair cost in Hendon (NW4)?
Roof repair costs vary depending on the extent of damage and roof type. Minor repairs, such as replacing a few tiles or fixing small leaks, typically cost £300-£800. More extensive repairs involving valleys, flashing, or multiple areas range from £800 to £2,000. Flat roof repairs generally cost £500-£1,500. We provide free inspections and detailed quotes before any work begins, with no hidden costs or surprise charges.
2. When should I repair vs. replace my roof?
Repair is usually sufficient if leaks are localised to one or two areas, fewer than 20-30% of tiles need attention, the roof structure and battens remain sound, and the roof is under 60 years old and made of good-quality materials. Replacement becomes necessary when you experience multiple leaks across different areas, when battens and timbers show significant rot, when more than 30-40% of tiles are damaged or missing, or when the roof has reached the end of its expected lifespan (typically 60-100 years, depending on materials). We’ll assess your roof honestly and recommend the most cost-effective solution.
3. Do 1930s roofs need breathable membranes?
No—1930s roofs were built without breathable membranes, and this was standard construction practice at the time. These roofs relied on proper tile overlap and ventilation for weather protection. Many function perfectly well after 90-100 years without membranes. However, when replacing a 1930s roof, we recommend installing modern, breathable membranes to provide enhanced protection against condensation and water ingress. This upgrade doesn’t mean your existing roof was “wrong”—it simply incorporates modern improvements while respecting the original construction methods.
4. How quickly can you respond to a roof leak in Hendon?
We offer 24/7 emergency roofing services across Hendon and NW4 with an average response time of 90 minutes for urgent leaks and storm damage. When you call our emergency line, we’ll provide immediate advice on minimising damage until we arrive, then assess the situation and provide temporary weatherproofing to protect your property. We’ll follow up with a detailed quote for permanent repairs. For non-emergency inspections and planned work, we typically schedule assessments within 2-3 working days.
5. What materials do you recommend for flat roofs?
We recommend GRP (fibreglass) flat roofing for most applications due to its 30-50 year lifespan, seamless waterproof finish, excellent weather resistance, and low maintenance requirements. GRP costs more initially but offers superior longevity. High-performance felt systems are cost-effective alternatives with 20-30 year lifespans, suitable for garages and less critical areas. We don’t recommend traditional three-layer felt systems because they have shorter lifespans (15-20 years) and higher failure rates. During your consultation, we’ll assess your specific needs and recommend the best material for your budget and property type.
6. Can you help with insurance claims for storm damage?
Yes. We regularly assist Hendon homeowners with insurance claims following storm damage, providing detailed damage assessments with photographs, written reports documenting the cause and extent of damage, itemised quotes for repairs that meet insurance requirements, and advice on the claims process and working with loss adjusters. We can complete temporary repairs to prevent further damage while your claim is processed. Contact us immediately after storm damage occurs—prompt action helps protect your property and strengthens your insurance claim.
7. Do I need planning permission for roof work in Barnet?
Most roof repairs and like-for-like replacements don’t require planning permission. However, you may need permission if you’re significantly altering the roof height or shape, adding dormers or roof extensions, working on a listed building or property in a conservation area, or changing roofing materials in a way that affects the building’s character. We’re familiar with Barnet Council’s design guidelines and can advise on planning requirements during your free consultation. For complex projects, we recommend confirming with Barnet’s planning department.
8. Do you work on Art Deco homes from the 1930s in Hendon?
Absolutely. We specialise in period property roofing and have extensive experience working on 1930s Art Deco homes throughout Hendon, particularly in Shirehall Estate, Sunny Hill, and similar areas. We understand the unique construction methods used in pre-war properties, can source appropriate materials that match original tiles and slates, respect the architectural character while incorporating modern improvements, and comply with conservation area requirements where applicable.
