Homeowners across Milton Keynes and nearby towns rate us highly, with 80+ 5-star reviews on Checkatrade and a 5-star rating on Google. From emergency make-safe to permanent repairs, we respond quickly and stand by our workmanship.

1) First 10 minutes – safety first

Water and electrics do not mix, and ceilings can become heavy quickly. Before anything else:

  • Keep people and pets away from any area where the ceiling is bulging or dripping heavily.
  • If water is near lights, a fuse board, or sockets, switch off the affected circuit at the consumer unit. If unsure, switch off the main power and use torches.
  • Move furniture, rugs, and valuables out of the drip zone. Cover what you cannot move with plastic or waterproof sheets.
  • Place buckets or containers under drips. Lay towels to reduce splashing and protect floors.
  • If a ceiling is visibly bulging, you can reduce structural stress by carefully creating a controlled release into a bucket with a screwdriver – only if you are confident there are no electrics in that section and it is safe to do so. If unsure, wait for a professional.

2) Diagnose the leak without going on the roof

Never climb onto a wet or windy roof. You can still gather useful clues from inside the property:

Check the loft or attic (if safe to access)

  • Use a torch to look for active drips, damp underlay, water trails on rafters, or daylight through the roof covering.
  • Trace water uphill along timbers – leaks often travel before dripping elsewhere.
  • Check around chimney stacks, valleys where roof slopes meet, skylight frames, and pipe penetrations.

Flat roofs on extensions and garages

  • Leaks often occur at seams, upstands, rooflight kerbs, and outlets. From inside, note the location relative to features above.
  • Ponding after a downpour can stress older felt systems or poorly detailed EPDM or GRP joints.

Skylights and roof windows

  • Inspect plasterboard reveals for staining. Look for water tracking around the frame. Internal condensation is sometimes mistaken for a leak.

Chimneys and flashings

  • Staining near a chimney breast usually indicates failed lead flashing, porous bricks, or missing mortar where repointing is needed.

Gutters and overflows

  • During heavy rain, blocked gutters can overflow and force water behind fascias or under tiles. This is common with autumn leaf fall on MK’s leafy estates.

Simple notes or photos will speed up diagnosis and repair.

3) Quick do’s and don’ts during heavy rain

Do

  • Contain water with buckets and towels.
  • Turn off affected electrics.
  • Document the issue with photos or video, with timestamps and weather conditions.
  • Call a professional roofer for guidance. Many leaks can be stabilised same day or next day.

Don’t

  • Do not climb on the roof in rain or high winds.
  • Do not peel back tiles or slates. This can make leaks worse.
  • Do not apply DIY sealants everywhere. Misapplied products can trap moisture and void warranties.
  • Do not ignore a small drip. Ceilings can fail suddenly as plasterboard becomes saturated.

4) Temporary measures while you wait

If it is safe and you are confident, you can take small, interior-only measures:

  • Protect floors with plastic sheeting and towels to reduce damage.
  • Ventilate by opening nearby windows once rain eases to help drying and reduce mould risk.
  • Run a dehumidifier in damp rooms if you have one.

Exterior tarps or roof tapes should be left to professionals. Wet roofs are extremely hazardous, and poorly fitted tarps can cause additional damage.

5) When to call an emergency roofer and our process

Call immediately if you have any of the following:

  • Active dripping or streaming water
  • Bulging ceilings or visible sagging
  • Water near electrics
  • Flat roof ponding with interior leaks

What Maxwell’s Roofing does on arrival

  • Make safe first – interior protection, controlled relief of trapped water if needed, and electrical safety guidance.
  • Diagnose properly – visual inspection of coverings, flashings, valleys, and loft checks. Where appropriate and safe, we carry out external inspection. We can use drone inspection on suitable properties when permitted.
  • Stabilise – professional-grade temporary weathering so further ingress stops.
  • Repair – where possible, permanent repairs on the first visit. If specialist materials are needed, we schedule a quick return.
  • Clear pricing – straightforward quotes with no pressure.
  • Documentation – photos and a written summary for your records or insurer.

For urgent help call 07311091804

6) Insurance and documentation

Storm-related water ingress is often insurable. To support a claim:

  • Record date, time, and weather conditions such as high wind or heavy rain.
  • Take clear photos or video of interior damage and any visible external issues from ground level.
  • Keep receipts for emergency works, drying equipment, and cleaning.
  • Ask us for a written report and repair invoice describing cause and remedy. We provide these on request.

We are happy to speak with your insurer or loss adjuster to clarify scope, materials, and compliance.

7) Common causes of rain leaks in Milton Keynes homes

We regularly repair the following issues across Milton Keynes, Bletchley, Newport Pagnell, Stony Stratford, Bradwell, Great Linford, Bedford, and Northampton:

1) Slipped, cracked, or missing tiles or slates

  • High winds can dislodge tiles. UV and frost cycles weaken older clay or concrete tiles and nail fixings.

2) Ridge and hip mortar failure

  • Cracked or missing mortar allows wind-driven rain to penetrate. Dry ridge systems are a durable upgrade option.

3) Lead flashing defects

  • Poorly wedged or sealed flashings at chimneys and abutments are a prime source of leaks.

4) Valley problems in tile, lead, or GRP

  • Blocked valleys or cracked liners divert water into the roof during downpours.

5) Flat roof membrane failure

  • Aged felt can blister or split. Poor detailing on EPDM or GRP at upstands, outlets, or seams lets water track inside.

6) Blocked or undersized gutters

  • Overflow pushes water behind fascias or under the first course of tiles.

7) Chimney deterioration

  • Porous brickwork, failed pointing, or damaged pots allow water ingress.

8) Skylight or roof window detailing

  • Incorrect flashing kits or degraded seals can mimic a roof leak.

9) Underlay degradation

  • Older felts become brittle. When secondary protection is lost, minor defects turn into leaks during heavy rain.

8) Preventing the next leak – maintenance checklist

Small, regular maintenance prevents most heavy-rain leaks and extends roof life.

Seasonal tasks

  • Autumn: Clear gutters and valleys after leaf fall. Check downpipes for blockages.
  • Winter: After storms, look from ground level for slipped tiles or debris.
  • Spring: Inspect flat roofs for winter damage. Check perimeters and rooflight kerbs.
  • Summer: Plan proactive repairs and upgrades during dry spells for best results.

Ventilation and insulation

  • Ensure adequate loft ventilation to prevent condensation. Persistent moisture can mimic leaks and damage timbers.
  • When refurbishing more than 25 percent of your roof, updated insulation may be required. We advise during quotes.

Professional inspections

  • Every 12 to 24 months, book a roof inspection to catch small issues early. We offer visual and drone surveys with clear recommendations.

9) Compliance and quality – UK Building Regulations

We repair and refurbish roofs in line with relevant UK standards and Approved Documents. On every job we consider:

  • Part A – Structure: Suitable fixings and load assessments when changing materials or coverings.
  • Part B – Fire Safety: Appropriate materials and details. Flat roofing systems should meet the right fire performance such as BROOF(t4).
  • Part C – Resistance to Moisture: Detailing to keep water out and manage condensation risks.
  • Part F – Ventilation: Adequate airflow to prevent damp and mould, especially in lofts and conversions.
  • Part L – Energy Efficiency: Refurbishments affecting more than 25 percent of the roof usually trigger insulation upgrades.

Where Building Control notification is required, we guide you and can liaise with the local authority. Where self-certification via recognised competent person schemes may apply, we explain options and ensure materials and workmanship follow manufacturer guidance and best practice.

Roof Leak FAQs (Milton Keynes)

Can you fix a leak while it is still raining?

In many cases we can make the area safe and apply temporary weathering during rain, then return for a permanent repair in dry conditions. It depends on access and safety.

Should I poke a hole in a bulging ceiling?

Only to release trapped water in a controlled way and only if you are certain there are no electrics nearby. If in doubt, wait for a professional. Bulging ceilings can fail suddenly.

Will a small leak dry out on its own?

Some drying will occur, but hidden moisture can lead to mould and timber damage. It is best to identify and fix the cause promptly and then ventilate or dehumidify the area.

How quickly can you attend?

For urgent leaks we aim for same day or next day attendance wherever possible across Milton Keynes and surrounding towns.

Can you match my existing tiles or flat roof system?

Yes. We source matching tiles or slates where possible and offer compatible flat roof systems such as EPDM, felt, or GRP based on your roof and budget.

Do I need Building Control for a leak repair?

Small, like-for-like repairs usually do not. Replacing or refurbishing more than 25 percent of a roof typically does. We will advise on requirements.
