Common Flat Roof Problems We Fix
Flat roofs on extensions, garages, and porches are prone to specific issues. We diagnose and repair all flat roof problems across Cambridgeshire.
Leaking Flat Roofs
Water pooling, blistering felt, or failed seams cause leaks. We locate the source and repair it properly, whether it's a small patch or requires re-covering.
Ponding Water
Water collecting in low spots accelerates deterioration. We improve drainage and, where necessary, adjust falls to prevent water pooling.
Blistering and Bubbling
Trapped moisture causes blisters in felt roofs. We cut out damaged sections, dry the roof properly, and repair with matching materials.
Cracked or Split Surfaces
Age, UV damage, and temperature changes cause cracks. Small cracks can be sealed; extensive cracking usually requires replacement.
Failed Flashing and Upstands
Where flat roofs meet walls, poor flashing causes leaks. We repair or replace lead or felt upstands to create watertight joints.
Perished Felt Roofing
Old felt becomes brittle and tears. Once felt has deteriorated significantly, overlaying with GRP or EPDM is often more cost-effective than re-felting.
Damaged GRP or EPDM
Modern flat roofs can be punctured or torn. GRP can be patched and recoated; EPDM can be repaired with specialist adhesives and patches.
Poor Installation Issues
DIY or substandard installations often fail prematurely. We rectify poor workmanship and install flat roofs properly to last.

Flat Roofing Costs in Cambridgeshire
Flat roof costs depend on size, system chosen, and existing roof condition. Here's what affects pricing and typical costs in our area.
What Affects Flat Roof Costs?
Roof size: Larger roofs cost more but have lower per-square-metre costs. Small roofs have higher per-m² prices due to minimum material quantities.
System chosen: Felt is most economical. GRP and EPDM cost more but last longer and require less maintenance. Liquid systems vary depending on application.
Access and height:
Ground-level garages are straightforward. First-floor extensions or difficult access increase labour costs.
Existing roof condition: If decking or joists are rotten, these need replacing first. We identify structural issues during the survey.
Additional work: New fascias, soffits, guttering, or roof lights add to the overall project cost but are often worth doing while scaffolding is up.
The only accurate way to get an idea of costs is to have us inspect the work required and put together a free quote.
Flat Roof Repair or Replacement?
Not sure whether to repair or replace your flat roof? Here's how to decide:
Repair When:
Leak is localised to a small area
Flat roof is less than 10 years old
Overall condition is good except for one issue
Repair cost is significantly less than replacement
You need a temporary fix before planned replacement
Replace When:
Flat roof is 15+ years old
Multiple areas are leaking or failing
Blisters and cracks are widespread
You've had multiple repairs in recent years
Underlying decking or structure is damaged
You want to upgrade to a better system
Still Unsure?
Our free inspection will give you honest advice. We'll explain whether repair is viable or if replacement makes more sense for long-term reliability and value.
Frequently Asked Questions
How long does a flat roof last?
It depends on the system. Felt roofs last 15-20 years with maintenance. EPDM rubber lasts 20-25 years. GRP fibreglass lasts 20-30 years. Quality installation and proper maintenance significantly affect lifespan.
Can you repair a leaking flat roof?
Often yes, if the leak is localised and the roof is in reasonable overall condition. We locate the source, assess whether repair is viable, and carry it out properly. Some leaks indicate the roof has reached the end of its life and needs replacing.
Which flat roof system is best?
It depends on your priorities. GRP fibreglass offers the best durability and longevity. EPDM rubber is cost-effective and quick to install. Felt is most economical upfront. We'll recommend the best option based on your property, budget, and requirements.
How quickly can you repair an emergency leak?
For emergency flat roof leaks during business hours (Monday-Friday 8am-6pm, Saturday 9am-4pm), we aim to respond the same day. We'll make the roof weathertight and arrange permanent repair or replacement as needed.
Do flat roofs always leak?
No. Properly installed modern flat roofs using quality systems (GRP, EPDM) are extremely reliable. Problems occur when flat roofs are poorly installed, use substandard materials, or aren't maintained. Our installations are guaranteed for 15 years.
Can you install a flat roof over an existing one?
Sometimes. If the existing decking is sound, we can overlay with GRP or EPDM. This saves on removal costs. However, if there's rot or structural issues, complete replacement is necessary. We assess this during the survey.
How much fall does a flat roof need?
Despite the name, flat roofs aren't completely flat. They need a minimum fall (slope) of 1:80 to prevent water pooling. Ideally, 1:40 provides better drainage. We ensure proper falls when installing new flat roofs.
What maintenance do flat roofs need?
GRP and EPDM need minimal maintenance – an annual inspection and clearing debris is usually sufficient. Felt roofs benefit from periodic coating to extend lifespan. We provide maintenance advice with all installations.
Can you add roof lights or windows?
Yes. Flat roofs are ideal for roof lights. We can incorporate these into new installations or retrofit them to existing flat roofs. This adds natural light to extensions and converted spaces.
Do you notify building control?
Where required by building regulations, yes. Some flat roof replacements require building control notification. We handle this process and ensure all work complies with current regulations.
What guarantee do you provide?
New flat roof installations come with our 15-year guarantee covering materials and workmanship. Repairs carry varied guarantees depending on the work carried out – we'll confirm this in your quotation.
Can flat roofs be insulated?
Yes. We install warm roof systems with insulation above the deck, or cold roof systems with insulation between joists. Warm roofs are generally better and meet current building regulations for energy efficiency.
