Harlow is one of Britain's eight original post-war new towns, designated in 1947 and built largely between the 1950s and 1970s to rehouse families from London's East End. Designed by Sir Frederick Gibberd, it was a planned town from the outset — which means its housing stock is unusually uniform in age and construction type compared to most Essex towns.
That uniformity has a practical consequence for homeowners: a large proportion of Harlow's properties were built at the same time, with the same materials, and those materials are now reaching the end of their designed service life simultaneously. Flat roofs that were installed in the 1960s and 1970s, concrete interlocking tiles from the 1980s, and original fascia boards from the post-war build are all coming due for replacement or major repair across the town at the same time.
This guide explains what Harlow homeowners are most likely to encounter, what the options are, and what to look for when choosing a roofer.
Harlow's Housing Stock and Why It Matters for Roofing
Understanding Harlow's housing history helps explain why certain roofing problems are so common here.
Post-War Council and Social Housing (1950s–1970s)
The original new town housing — much of it now privately owned following right-to-buy — was built quickly and economically. Flat roofs were common on low-rise blocks and bungalows because they were cheaper to construct than pitched roofs. The felt systems used at the time had a designed lifespan of around 20–25 years. Many of these roofs have been overlaid or patched multiple times since, and are now well beyond any reasonable service life.
Concrete Interlocking Tiles (1970s–1990s)
Harlow's expansion through the 1970s and 1980s brought large numbers of properties with concrete interlocking tiles — a popular choice at the time because they were cheap, fast to lay, and required minimal maintenance in the short term. After 40–50 years, however, concrete tiles become porous, lose their surface coating, and begin to absorb water rather than shed it. Moss and algae growth accelerates the deterioration. Many Harlow properties with original concrete tiles are now at the point where a full re-roof is more cost-effective than continued patching.
1990s and 2000s New Builds
Harlow's more recent developments — particularly around Newhall and the southern expansion areas — used modern clay and concrete tiles with better longevity. These properties are generally in better condition, but are now old enough to need attention to flashings, valleys, and ridge mortar.
Common Roofing Problems in Harlow
1. Failing Flat Roofs
Flat roofs are more common in Harlow than in most Essex towns, and they are the single most frequent source of roofing enquiries we receive from the area.
The original torch-on felt systems used in the 1960s and 1970s have a characteristic failure pattern: the felt becomes brittle, develops hairline cracks, and eventually splits — particularly at seams, around upstands, and where the roof meets a parapet wall. Water pools in low spots and finds its way through. By the time a homeowner notices a damp patch on the ceiling, the water has often been tracking through the roof structure for months.
The modern solution is EPDM rubber roofing or GRP fibreglass — both of which offer 25–50 year lifespans, are fully waterproof, and require minimal maintenance. A flat roof replacement in Harlow typically takes one to two days and is significantly less disruptive than it sounds.

2. Deteriorating Concrete Interlocking Tiles
As described above, Harlow has a large number of properties with ageing concrete interlocking tiles. The signs that these tiles are failing include:
- Visible moss and algae growth — not just cosmetic; moss retains moisture and accelerates tile deterioration
- Colour fading and surface erosion — the tile surface becomes rough and porous
- Cracking and spalling — tiles begin to break, particularly at the edges and nibs
- Increased heating bills — porous tiles allow more heat loss through the roof
At a certain point, continued repair becomes uneconomical. If more than 20–25% of tiles on a roof are cracked, porous, or missing, a full re-roof is usually the right answer. Modern concrete or clay tiles are significantly better than those installed in the 1970s and 1980s, and a new roof will typically come with a 10–15 year workmanship guarantee.
3. Ridge and Hip Mortar Failure
The mortar that beds ridge tiles and hip tiles onto a pitched roof has a lifespan of around 20–30 years. On Harlow's older properties, this mortar is now crumbling, cracking, and in many cases falling away entirely. Loose ridge tiles are a safety hazard — a ridge tile weighs several kilograms and can cause serious injury if it falls — and they allow water into the roof structure at the highest and most vulnerable point.
Repointing ridge and hip mortar is a straightforward job that can usually be completed in a day. It is one of the most cost-effective pieces of preventive maintenance a homeowner can carry out.
4. Fascia, Soffit, and Guttering Deterioration
Harlow's post-war properties were built with timber fascia boards and soffits. After 50–70 years, these are often rotten, painted over multiple times, and no longer providing adequate support for the guttering. Sagging gutters pull away from the fascia, water overflows behind them, and the wall below begins to show damp.
Replacing timber fascias and soffits with uPVC is a permanent solution that requires no future painting or maintenance. It is usually done at the same time as a gutter replacement, and the combined job typically takes one to two days.
5. Chimney Problems
Many of Harlow's older properties have chimney stacks that are no longer in use but remain structurally part of the roof. These chimneys are a common source of leaks because:
- Flashing failure — the lead or mortar flashing where the chimney meets the roof deteriorates and allows water in
- Pointing failure — the mortar between the brickwork erodes, allowing water into the stack
- Pot and cowl deterioration — unused chimney pots allow rain directly into the stack
A chimney that is no longer in use can be capped and made weathertight relatively inexpensively. A chimney that is actively leaking needs prompt attention to prevent water damage to the roof structure and the rooms below.
Emergency Roofing in Harlow
Storm damage, sudden leaks, and missing tiles after high winds are a fact of life in Essex. Harlow's position in the Stort valley means it is exposed to weather coming from both the north and the east, and the town experiences its share of damaging storms.

- Skylights and rooflights damaged by falling debris
Re-Roofing in Harlow: What to Expect
If your Harlow property needs a full re-roof, here is what the process typically looks like:
Day 1–2: Strip and inspect The existing tiles or felt are stripped back to the roof structure. The rafters, battens, and sarking felt are inspected. Any rotten or damaged timber is replaced at this stage.
Day 2–3: Felt, batten, and tile New breathable roofing felt is laid, new treated timber battens are fixed, and new tiles are hung. Ridge and hip tiles are bedded in mortar or fixed with a dry-fix system.
Day 3–4: Finishing Flashings are dressed, valleys are lined, and any lead work is completed. The site is cleared and a final inspection is carried out.
A typical three-bedroom semi-detached house in Harlow takes three to four days to re-roof. We provide a full written quotation before any work begins, with no hidden costs.
Choosing a Roofer in Harlow
Harlow has no shortage of roofing contractors, but the quality varies considerably. Here is what to look for:
Public liability insurance — any roofer working on your property should carry a minimum of £2 million public liability insurance. Ask to see the certificate before work begins.
Written quotation — a reputable roofer will always provide a written quotation that specifies the materials to be used, the scope of work, and the price. Be wary of verbal quotes or quotes that arrive by text message.
Workmanship guarantee — most reputable roofing contractors offer a 10-year workmanship guarantee on new roofs and major repairs. This is separate from any manufacturer's guarantee on the materials.
Local references — a contractor who has been working in Harlow for a number of years will be able to provide references from local customers. Ask for them.
No upfront payment demands — a reputable contractor will not ask for full payment before work begins. A deposit of 10–25% is reasonable for larger jobs; anything more should be treated with caution.
Frequently Asked Questions
How much does a new roof cost in Harlow?
A full re-roof on a three-bedroom semi-detached house in Harlow typically costs between £5,000 and £9,000 depending on the roof size, pitch, tile specification, and the condition of the underlying structure. Flat roof replacements on extensions and garages typically cost between £800 and £3,000 depending on size and material. We provide free, no-obligation quotations — call 07836 559605 to arrange a survey.
How long does a roof repair take?
Most standard repairs — replacing slipped tiles, repointing ridge mortar, repairing flashings — can be completed in half a day to a full day. Larger repairs and full re-roofs take three to five days depending on the size of the roof.
Do I need planning permission to re-roof my house in Harlow?
In most cases, no. Re-roofing with the same or similar materials is permitted development in England. If you are changing the roof profile, adding a dormer, or the property is listed or in a conservation area, you may need planning permission. We can advise on this during the survey.
Can you repair a flat roof rather than replace it?
In some cases, yes. If the damage is localised — a split seam, a failed upstand, a small area of blistering — a repair is often the right answer. If the roof is more than 20–25 years old and showing widespread deterioration, a full replacement is usually more cost-effective in the long run. We will always give you an honest assessment.
Do you cover emergency call-outs in Harlow?
Yes. We provide 24/7 emergency roofing cover across Harlow and the surrounding area. Call 07836 559605 at any time.
