Roofing Contractor Derby – Reliable Roofing Services

TEL: 01332-327296

We are Derby House Extensions, based at Stenson Road, Derby, DE23 1LP. We have been in the building trade for over 20 years, working on homes and properties across Derby and Derbyshire. Roofing is one of our core services. Whether you need a single broken tile repaired or a complete new roof, we carry out every job with skilled tradesmen, proper preparation, and BBA approved roofing materials on every project.

If you are searching for a reliable, professional roofing contractor in Derby — you have found the right team.

In Derbyshire, roofs face a constant challenge. Cold winters, hard frosts, heavy rainfall, and strong winds put real pressure on older properties across Stenson, Littleover, Mickleover, Sinfin, Alvaston, Chaddesden, Chellaston, and Normanton. We know Derby's housing stock. We know the roof types, the recurring problems, and what the correct fix looks like every time.

And we make getting started easy — with a FREE Drone Roof Survey for every Derby homeowner, so you know exactly what condition your roof is in before spending a penny.

Call us on 01332-327296 for your free, no-obligation drone survey and quote today, or our home page if you require another service.

FREE Drone Roof Survey — See Your Roof Clearly Before You Commit to Anything

Most Derby homeowners have no idea what condition the top of their roof is actually in. From the ground, you can spot obvious problems — a missing tile, a sagging gutter. But the real picture is often hidden. Cracked ridge tiles, failed flashings, deteriorating felt, early moss penetration under tiles — these are the issues that cause the most damage and the most expensive repairs, precisely because they are invisible until water starts coming in.

That is why we offer every Derby homeowner a completely FREE Drone Roof Survey before any work is quoted or agreed.

What Our Drone Roof Survey IncludesUsing a professional-grade drone equipped with a high-resolution camera, our team captures detailed aerial imagery of your entire roof from multiple angles — without a single ladder touching your property and without any scaffolding being erected. The survey is fast, safe, and produces a clear visual record of every part of your roof.

Our free drone survey covers:

All tile and slate surfaces — identifying cracked, slipped, missing, or damaged tiles across the whole roof
Ridge and hip tiles — checking for displaced tiles, failed mortar bedding, and wind damage
Verge and eaves details — inspecting for gaps, movement, and deterioration
All flashings and leadwork — around chimneys, skylights, valleys, and abutments
Chimney stacks — checking pointing, flaunching, and stack condition in detail
Gutters and downpipes — identifying blockages, sagging, cracks, and failed joints
Flat roof areas — condition of membrane, ponding, splits, and edge details
Moss, algae, and lichen coverage — extent and location across the roof surface

Why a Drone Survey Changes Everything
A traditional roof inspection means someone climbing a ladder or erecting scaffold before any work has been agreed. A drone survey gives you a complete, detailed picture of your roof's condition from the safety of the ground — in a fraction of the time, with no disruption to your property.

The benefits for Derby homeowners are significant:

No scaffolding required — the survey is completed from ground level
No physical access to your roof — no risk of tiles being displaced or damaged during inspection
Complete roof coverage — every angle, including areas that are impossible to see from the ground
High-resolution images — you can see exactly what we see and make informed decisions
Written findings and recommendation — you receive a clear, plain-English summary of what the survey found and what we recommend
Completely free and no obligation — there is no charge and no pressure to proceed

Many Derby homeowners who book a free drone survey discover issues they had no idea existed. Catching them early — before water gets into the roof structure — is always significantly cheaper than dealing with the consequences later.

BBA Approved Roofing Materials — Why It Matters for Your Home

Every roofing material we use at Derby House Extensions carries BBA approval — the British Board of Agrément certification. This is not a marketing badge. It is an independent, rigorous quality standard that tells you exactly what you are getting when we install a new roof or carry out a repair on your Derby home.

What BBA Approval Actually MeansThe British Board of Agrément (BBA) has been the UK's leading independent construction product certification body since 1966. Before any product earns BBA approval, it undergoes:

Extensive laboratory testing — for durability, fire performance, thermal performance, and waterproofing
Weather resistance and wind uplift testing — including simulation of freeze-thaw cycles relevant to Derbyshire winters
Factory inspections — to confirm production quality is consistent batch after batch
On-site performance evaluation — assessing how the product performs under real UK conditions
Regular re-auditing — BBA certificates are formally reviewed to confirm standards are maintained

The result is independent, verified confirmation that the product does what it claims to do — and will continue to do so for the lifespan stated in the certificate.

Why BBA Approval Matters to You as a Derby Homeowner

Your roof will perform as promised — BBA approval means independent verification, not just a manufacturer's claim
Materials meet UK Building Regulations — BBA certified products are accepted by building control, local authorities, and insurance companies
Extended warranties are supported — many manufacturer warranties are only valid when BBA approved materials are correctly installed
Protection for your home insurance — insurers recognise and rely on BBA certification when assessing roofing work
Peace of mind — you are not a test subject for unproven materials; everything we install has been independently proven

When you receive a quote from Derby House Extensions, you are not just paying for labour. You are investing in materials that have been independently tested, certified, and proven to perform on UK roofs in UK conditions — including the cold, wet winters that Derbyshire delivers every year.

Is Your Roof Trying to Tell You Something?

Warning Signs That Your Derby Roof Needs AttentionYour roof gives you warning signs before it fails. Spotting them early — ideally through a free drone survey — can be the difference between a straightforward repair and a costly structural replacement. The longer a problem is left, the more water damage spreads into timbers, insulation, ceilings, and walls.

Here are the most common warning signs to look out for:

Missing, cracked, or slipped tiles — often visible from the ground or garden
Damp patches or water staining on ceilings — a clear sign water is already penetrating
Daylight visible from inside the loft — gaps in the roof structure needing immediate attention
A sagging or uneven roofline — indicates structural issues with battens, rafters, or decking
Moss, lichen, or algae on tiles — holds moisture and accelerates surface wear
Loose, cracked, or missing flashings — around chimneys, skylights, and roof valleys
Overflowing or blocked gutters — can cause water to back up under tiles and saturate roof timbers
Rising energy bills — a failing roof allows heat to escape and cold air to enter the property

Derby properties built between the 1930s and 1980s — which make up a large proportion of the housing stock in Normanton, Alvaston, Chaddesden, Spondon, and Oakwood — often have original concrete tile roofs at or past their expected lifespan. Our free drone survey is the fastest, safest, and most accurate way to establish the current condition of your roof — with no ladders, no scaffolding, and no commitment required.

Roof Repair or Full Replacement — Making the Right Decision

Not every roofing problem requires a full replacement. We will always give you a straight, honest answer — and our free drone survey means that answer is based on real visual evidence of your roof's actual condition, not a guess from the ground.

When a Repair Is the Right Choice

Damage is localised — a few broken tiles, a small isolated leak, or a failed flashing section
The roof structure, battens, and felt underlayer are all in sound condition
The roof is less than 15–20 years old
The problem has been identified early through the drone survey before water has penetrated the structure

When a Full Replacement Makes More Sense

Widespread tile damage, cracking, or slippage across large areas
Repeated leaks in different locations that repairs have not resolved
The roof is over 20–25 years old with general deterioration throughout
The felt underlayer has failed and water is collecting in the roof void
Roof timbers show signs of rot, water damage, or structural weakness identified during the survey
You are planning a loft conversion — replacing the roof at the same time avoids duplicate costs and disruption

For homeowners in Littleover, Sinfin, Mickleover, and Chellaston with 1950s–1970s semis, full replacement often works out better long-term value than a cycle of ongoing repairs. We project manage every replacement from scaffold erection to final sign-off. You always know exactly what is happening with your home.

Our Roofing Services in Derby & Derbyshire

Derby House Extensions offers a complete roofing service for homeowners and property owners across Derby and the wider Derbyshire area. We handle everything in-house — free drone survey, written quote, BBA approved materials, skilled installation, and written guarantee. No subcontracting. No hand-offs. One team, one guarantee, one point of contact from start to finish.

Pitched Roof Construction

A pitched roof — the sloped roof found on the majority of Derby homes — is our most common area of work. We carry out repairs, full replacements, and re-roofing across all pitched roof materials, all installed using BBA approved products.

Concrete Roof Tiling

Concrete tiles are the most widely used roof covering on homes across Derby and Derbyshire. They are found on the majority of post-war semis and terraced properties across Spondon, Alvaston, Oakwood, California, and Chaddesden. Durable, cost-effective, and widely available, we supply and fit BBA approved concrete tiles for full replacements and repairs, carefully matching existing profiles and colours where possible.

Clay Roof Tiling Derby

Clay tiles suit period properties, older homes, and conservation area properties. Derby has several conservation areas — including parts of the city centre, Darley Abbey, and Quarndon — where clay tiles are the appropriate and often required choice. We install BBA approved clay tiles on new roofs and replacement projects, with their natural finish and long lifespan making them a sound long-term investment.

Slate Roofing Derby

When properly installed using BBA approved slate, a natural slate roof can last well in excess of 50 years — often significantly longer. Many Victorian and Edwardian properties in areas like Kedleston Road, Duffield Road, and the streets around Derby Cathedral have original slate roofs. Slate is also the standard material for listed buildings and heritage properties across Derbyshire. We carry out slate repairs, full re-slating, and new slate installations across Derby, Belper, Matlock, Ashbourne, and the wider county.

Flat Roofing

Flat roofs are found on extensions, garages, bay windows, porches, and dormer windows across Derby. The flat roofing market has changed significantly. Older felt systems have been replaced by far more reliable modern alternatives — and we work with all of them, exclusively using BBA approved flat roofing systems on every installation.

Felt Roofing

We install BBA approved high-performance torch-on felt roofing systems with multiple reinforced layers — not single-layer felt. These significantly outperform older felt roofs in both lifespan and weatherproofing performance and are well suited to garage roofs and smaller flat areas across Derby.

GRP Fibreglass Roofing

GRP fibreglass is our most recommended flat roofing system for home extensions and bay windows across Derby, and it is one of the most popular choices across Derbyshire. We use only BBA approved GRP fibreglass systems. Applied as a seamless, one-piece membrane with no joints or seams — the points where older flat roofing systems typically fail first — BBA approved GRP fibreglass flat roofs typically carry a manufacturer guarantee of 20–25 years when installed correctly. It handles Derbyshire's wet winters and freeze-thaw cycles with ease and requires very little maintenance.

EPDM Rubber Roofing

We install BBA approved EPDM rubber membrane systems on larger flat roofs — typically on extensions, outbuildings, and garage roofs. Flexible, highly resistant to UV degradation, and proven in cold and wet conditions, BBA approved EPDM is an increasingly popular upgrade from failed felt systems across Derby suburbs including Mickleover, Sunnyhill, Chellaston, and Alvaston. A correctly installed BBA approved EPDM roof can last in excess of 40 years.

Not sure which flat roofing system is right for your property? Our free drone survey will assess the existing roof, and we will give you a clear recommendation — with the reasons explained in plain English. Call 01332-327296.

Emergency Roofing

Storm damage, blown-off tiles, and sudden leaks cannot wait. A compromised roof allows water into your home rapidly, causing damage to ceilings, plasterwork, insulation, and roof timbers that spreads far beyond the original entry point.

We offer emergency roofing call-outs across Derby and the surrounding Derbyshire area. Call us immediately on 01332-327296. We will attend as quickly as possible, make the roof safe and weathertight, and provide a clear written quote for the permanent repair — using BBA approved materials throughout.

Common emergency call-outs we respond to in Derby include:

Storm-damaged, blown-off, or badly slipped tiles
Cracked or displaced ridge tiles after high winds
Failed chimney flashings allowing water into bedrooms or loft spaces
Damaged flat roofs leaking into extensions or garages
Fallen chimney pots or damaged stack brickwork
Storm damage to fascias, soffits, and guttering

Do not leave an active leak. Water damage compounds quickly. The sooner the roof is made safe, the lower the overall cost of putting things right. Call 01332-327296 any time.

Chimney Repairs and Leadwork Derby

Chimneys are among the most common sources of roof leaks on Derby homes — particularly on pre-1970s properties with multiple stacks that may not have been touched in decades. Our free drone survey regularly identifies chimney issues that are completely invisible from ground level but are actively allowing water into the property.

We carry out all chimney-related roofing work across Derby and Derbyshire, using BBA approved lead and ancillary materials throughout:

Lead flashings — re-dressing or replacing code-rated lead at the base and sides of chimney stacks
Chimney pointing and repointing — removing and replacing failed mortar joints before water penetrates the stack
Chimney stack repairs — rebuilding or repointing deteriorating brickwork from scaffold
Chimney pot removal and capping — for unused stacks where fireplaces have been sealed
Flaunching repairs — replacing cracked or crumbling mortar at the top of the chimney stack
Lead valley work — relining or replacing lead valleys between roof sections on complex rooflines

We use code-rated lead sheet throughout, cut and dressed to the correct profile. Lead work done to the right standard with the right materials lasts for decades. Properties in older Derby areas — Normanton, Peartree, Wilmorton, and the streets around Derby city centre — regularly need chimney attention and are among our most frequent call-out areas.

Dry Verge and Dry Ridge Systems

If your property has mortar-bedded ridge tiles or mortar-pointed verge edges, you are living with a recurring maintenance liability. Mortar cracks, shrinks, and fails — accelerated by the freeze-thaw cycles that Derbyshire winters produce every year. When it fails, ridge tiles lift or slide and the roof becomes vulnerable to both water ingress and wind damage.

We install BBA approved dry ridge and dry verge systems — replacing mortar with mechanical fixings that lock tiles securely in place for the lifetime of the roof.

The benefits for Derby homeowners:

No mortar to crack, shrink, or require re-bedding every 10–15 years
BBA approved mechanical fixings rated and tested for UK wind loading conditions
Far more resistant to wind uplift — critical on exposed Derby and Derbyshire properties
Particularly suited to Derbyshire's climate, where mortar failure is one of the most common roofing maintenance issues our drone surveys identify
Significantly reduced long-term maintenance costs
Cleaner, sharper roofline finish

If you are having a full re-roof, upgrading to BBA approved dry systems at the same time adds little to the overall cost and eliminates a recurring maintenance issue for the lifetime of the new roof.

Guttering, Fascias, and Soffits

Guttering, fascias, and soffits are working parts of your roof system. When they fail, rainwater runs down your walls instead of being directed safely away from the property — leading to damp, cracked render, stained brickwork, and damage to window and door frames over time.

We supply and fit BBA approved roofline products throughout, including:

uPVC fascia boards — white, black, and woodgrain finishes to suit your property
uPVC soffit boards — ventilated where required to allow airflow and prevent loft condensation
Half-round, ogee, and square-profile guttering and downpipes — in uPVC or cast iron
Gutter repairs — resealing leaking joints, re-aligning sagging runs, clearing blocked downpipes
Cast iron guttering and rainwater goods — for period properties and conservation areas
Full uPVC roofline packages — fascia, soffit, and guttering replaced together

Our free drone survey often identifies guttering issues that are not visible from the ground — sagging sections, failed joints at the back of gutters, and deteriorating fascia boards hidden behind guttering. This means you get a full and accurate picture before any work is quoted. We carry out roofline work across Derby, Long Eaton, Ilkeston, Belper, Heanor, Ripley, Swadlincote, Burton on Trent, and Ashbourne.

Roof Cleaning

Moss and algae are not just cosmetic problems. Left untreated, moss holds moisture against the tile surface, accelerates tile degradation, and over time works its way under the tiles — eventually allowing water into the roof structure.

Regular professional roof cleaning is one of the most cost-effective maintenance steps a Derby homeowner can take to extend the working life of an existing roof and avoid premature replacement. Our drone survey will show you exactly how much moss coverage your roof has and where it is most severe — so the cleaning is targeted and the outcome is measurable.

Our roof cleaning process:

Apply a professional-grade biocidal treatment to kill moss, algae, and lichen at the root
Mechanically clear loose moss from the tile surface once treated
Pressure wash where the tile type allows, removing built-up growth and surface debris
Apply a post-treatment protective solution to inhibit regrowth for an extended period

Properties in tree-lined Derby areas — Allestree, Darley Abbey, Little Eaton, and Breadsall — accumulate moss and algae significantly faster than more exposed locations. An annual or biennial cleaning programme keeps tiles in good condition and avoids premature re-roofing.

Planning Permission for Roof Work in Derby

In the majority of cases, no planning permission is required. Replacing a roof on a standard residential property in Derby on a like-for-like basis falls under permitted development rights.

There are situations where approval may be needed:

Conservation areas — Derby has several, including Darley Abbey, parts of the city centre, and Quarndon. Materials and appearance may need to match existing character
Listed buildings — all roofing work on listed buildings requires listed building consent regardless of scope
Structural changes to the roofline — altering the pitch, height, or shape typically requires planning permission
Loft conversions that change the external roofline — planning advice should be sought before work is agreed

If you are unsure, Derby City Council's planning department can advise over the phone. We have over 20 years of experience working within Derby's planning framework and are happy to help you understand what applies to your property.

What Guarantees Should You Expect From a Derby Roofer?

Written guarantees before work starts — not verbal promises after the job is done.

Here is what to look for:

Written workmanship guarantee — a reputable roofer provides a written guarantee on labour, typically for a minimum of 10 years
BBA approved manufacturer product warranties — because we use BBA approved materials, manufacturer warranties are fully supported and documented. You receive a copy of every relevant warranty
Public liability insurance — always ask to see a current certificate before work begins
Employers' liability insurance — required by law when a contractor employs workers
Insurance-backed guarantee (IBG) — protects you if the company ceases trading; available on request for qualifying projects

At Derby House Extensions, all roofing work is completed using BBA approved materials and backed by a written workmanship guarantee. We provide full documentation — insurance certificates, BBA material warranties, and written guarantee — on request and before work begins.

How to Spot a Legitimate Roofing Contractor in Derby

Rogue traders remain a genuine problem in the roofing industry. Uninvited door-knocking after a storm, large cash deposit demands, and vague verbal quotes with nothing in writing are all serious red flags.

Here is how to protect yourself:

Never pay the full cost upfront — a reasonable deposit may apply to large projects, confirmed in writing only
Insist on a full written quote — covering materials, labour, scaffolding, waste removal, VAT, start and finish dates, and payment schedule
Ask specifically whether BBA approved materials will be used — any contractor worth hiring should be able to confirm this immediately
Check verifiable reviews — Google, Checkatrade, or Trustpilot from named customers in Derby and Derbyshire
Ask for current proof of insurance — a legitimate contractor provides this immediately
Check how long they have been trading — a contractor with a long, local, verifiable track record is the safer choice
Be cautious of cold-callers — reputable roofing companies do not knock doors uninvited

Derby House Extensions has been trading for over 20 years from our base at Stenson Road, Derby, DE23 1LP. Our quotes are fully itemised and transparent. We use BBA approved materials on every project. And we start every job with a free drone survey so you know exactly what you are paying for and why.

Roofing and Loft Conversions Derby

If you are planning a loft conversion, the roof is not just part of the project — it is the most critical element of the project. Getting it right from the outset determines structural integrity, watertightness, insulation performance, and long-term durability.

We carry out all roofing work as part of full loft conversion projects across Derby and Derbyshire, using BBA approved materials throughout:

Dormer construction — new roof sections built outward to create head height and floor space
Hip-to-gable conversions — restructuring a hipped roof end to a gable to maximise internal volume
Velux and roof light installation — BBA approved roof window systems adding natural light without altering the external roofline
Mansard conversions — altering the roof pitch and structure to maximise internal volume
Full roof replacement as part of conversion — where the existing roof is at the end of its life

Our loft conversion and roofing teams work on the same project together. One company. One point of contact. One written guarantee. Visit our loft conversions page or call 01332-327296 to discuss your project.

Frequently Asked Questions — Roofing Contractor Derby

What is a drone roof survey and is it really free?

Yes — completely free and with no obligation. We use a professional-grade drone equipped with a high-resolution camera to capture detailed aerial imagery of your entire roof from multiple angles, without any ladders or scaffolding touching your property. You receive a clear summary of what the survey found and what we recommend. There is no charge and no pressure to proceed with any work.

What does BBA approved roofing materials mean?

BBA stands for the British Board of Agrément — the UK's leading independent construction product certification body. BBA approved materials have undergone rigorous independent testing for durability, weatherproofing, fire performance, and thermal performance, and they comply with UK Building Regulations. Using BBA approved materials means your roof is built with products that have been independently proven to perform as claimed — not just marketed as high quality. All materials we use carry BBA approval.

How much does a new roof cost in Derby?

The cost of a new roof in Derby depends on the property size, the materials chosen, and the complexity of the job. Our free drone survey gives us — and you — an accurate picture of the roof before we quote, so you receive a fully itemised written figure with no hidden extras. This is always the most accurate starting point, rather than an estimate based on limited information.

Should I repair or replace my roof in Derby?

Our free drone survey is the most reliable way to answer this question accurately. If damage is localised and the roof structure is sound, a repair is the right answer. If we see widespread wear, repeated leaks across different areas, or structural deterioration throughout, replacement typically offers better long-term value. We will always give you a straight, honest assessment — we will never recommend a replacement where a repair will genuinely solve the problem.

How long does a roof replacement take in Derby?

A standard pitched roof replacement on a 3-bedroom semi in Derby typically takes 3 to 5 working days. Larger or more complex roofs take longer. Flat roof replacements on extensions or garages are usually completed in 1 to 2 days. We give you a realistic written timescale before work begins and keep you informed at every stage.

Do I need planning permission to replace my roof in Derby?

In most cases, no. Like-for-like replacements fall under permitted development rights. If your property is in a Derby conservation area — such as Darley Abbey or parts of the city centre — or is a listed building, or involves structural changes to the roofline, approval may be required. We are happy to advise on this during the free survey visit.

Is scaffolding included in your roofing quotes?

Yes. Scaffolding is a legal requirement under the Work at Height Regulations and we include it in every project quote. What you are quoted is the complete cost — no separate scaffold invoices and no surprises on the final bill.

Call us on 01332-327296 or use the contact form at derbyhouseextensions.co.uk. We will arrange a convenient time, attend your Derby property, complete the drone survey, and walk you through the findings — with no charge and no obligation whatsoever.
