Your Most Common Roofing Questions, Answered

How Long Does a Roof Actually Last?

A well-fitted pitched roof using concrete or clay tiles will typically last between 50 and 80 years, though the felt underlayer beneath the tiles often degrades after 30 to 40 years and may need attention before the tiles themselves fail. Slate roofs, particularly those using natural Welsh or Spanish slate, can last well over a century if the fixings are kept in good order.

Flat roofs have a shorter lifespan, but modern systems give considerably better performance than the old felt-and-bitumen jobs that gave flat roofing a poor reputation. A quality GRP (fibreglass) or EPDM rubber flat roof fitted today should last 25 to 40 years with minimal maintenance.

In Mildenhall and the surrounding Breckland area, the climate is drier than much of the UK, but easterly winds, hard frosts, and occasional heavy downpours still put roofs under real seasonal stress. We regularly inspect roofs across Lakenheath, Beck Row and surrounding villages where properties have been standing since the 1950s — and many original roofs are still serviceable with targeted repairs.

Do I Need Planning Permission to Replace My Roof?

In most cases, replacing a roof with the same type of material is considered permitted development and does not require planning permission. However, there are important exceptions. If your property is a listed building, or sits within a conservation area, you will likely need consent before carrying out any roofing work — including like-for-like replacements.

Using different materials, altering the roof line, or adding rooflights may also trigger a planning application. We always recommend checking with West Suffolk Council before work begins if there is any doubt. The GOV.UK planning guidance sets out the rules clearly, and a quick phone call to the local planning office costs nothing.

Building regulations are a separate matter. Replacing a roof does fall under Part L (energy efficiency) of the Building Regulations, so the work must meet current thermal performance standards. We handle all required notifications as part of our roof replacement service.

How Do I Know If My Roof Needs Repairing or Replacing?

This is the question we get asked most often, and the honest answer is: it depends on the extent and location of the damage. A handful of slipped or cracked tiles, a small area of failed flashing around a chimney, or a blocked valley are all straightforward repair jobs. A roof where the felt underlayer has rotted, the battens are soft, or the majority of tiles are spalling and porous is a candidate for full replacement — patching it will only delay the inevitable and often costs more in the long run.

Warning signs that warrant a proper inspection include persistent damp patches on ceilings, visible daylight in the loft space, granules from felt collecting in your gutters, and moss or lichen growth that has lifted tiles at their edges. Our team offers free roof surveys across Mildenhall and the surrounding area — it is always better to get an accurate diagnosis than to guess from ground level.

For straightforward issues, our roof repairs service covers everything from individual tile replacements to re-bedding ridge tiles and repointing verges.

What Is the Best Material for a Flat Roof?

GRP (fibreglass), EPDM rubber, and torch-on felt are the three systems most commonly installed on domestic flat roofs in the UK. GRP gives a hard, seamless finish that is particularly good on complex shapes and around penetrations like soil pipes and rooflights. EPDM is highly flexible, handles temperature extremes well, and is straightforward to repair. Torch-on felt is a cost-effective option for straightforward areas but tends to have a shorter lifespan than the other two.

For most homes in this area — including bungalows with flat roof extensions and garages across Red Lodge and Fordham — we typically recommend GRP or EPDM for their longevity and low maintenance requirements. You can read more about the systems we install on our flat roofing service page.

Should I Use a Roofing Contractor Who Is Registered?

Yes, always. A registered contractor has agreed to operate to a defined standard of workmanship and can usually offer a manufacturer-backed guarantee on materials as well as their own labour warranty. The National Federation of Roofing Contractors (NFRC) maintains a directory of vetted member companies if you want an independent starting point.

Be cautious of unsolicited door-knocking, cash-only quotes, or contractors who cannot provide a local address and references. Roofing fraud is unfortunately common after storms, when homeowners see visible damage and feel pressure to act quickly. A trustworthy roofer will put everything in writing before work starts.
