Roof Leaks: Causes, Signs, Repairs & When to Call a Roofer

A leaking roof should not be ignored. Even a small leak can allow water into the roof structure and eventually cause damp, damaged insulation, timber problems or damage to ceilings and walls.

The good news is that many roof leaks can be repaired when the problem is identified early. The first step is understanding where the water is coming from and what caused the leak.

Advance Roofing North West provides roof repair services across Cheshire, including roof leak repairs, roof restoration, lead repairs, slate and tile replacement, ridge tile repairs and chimney-related roofing work.

What are the common signs of a leaking roof?

A roof leak is not always obvious from outside the property. Common warning signs include:

• Water marks on ceilings or walls
• Damp patches around the roof area
• Dripping water during or after rainfall
• Missing or slipped roof tiles
• Cracked or damaged slates
• Damaged lead flashing
• Water around a chimney
• Damp or damaged roof timbers
• Mould or a musty smell in the loft
• Water entering through a skylight

If you notice one of these problems, identifying the source early can help prevent a small roofing issue from becoming a larger repair.

What causes a roof to leak?

There are several possible causes of roof leaks.

Damaged or missing tiles

Tiles can become cracked, loose or displaced, particularly after strong winds and storms. Damaged tiles can leave areas of the roof exposed to rainwater.

Advance Roofing’s roof repair service includes slate and tile replacement and ridge tile repairs.

Damaged leadwork

Lead flashing is commonly used around areas such as chimneys and roof junctions. If lead becomes cracked, split, damaged or worn, water can enter the roof.

Chimney problems

A damaged chimney stack, deteriorated pointing or defective flashing can allow water into the roof.

Chimney repair work can include repairs to the stack and flashing around the chimney.

Flat roof damage

Flat roofs can develop leaks because of damaged waterproofing, ageing materials, poor drainage or problems around roof edges and penetrations.

Advance Roofing provides several flat roofing systems, including EPDM, GRP/fibreglass, felt and metal roofing.

Storm damage

Strong winds can dislodge tiles, damage flashing or expose vulnerable sections of a roof.

After severe weather, it is worth checking the roof for visible damage rather than waiting for water to appear inside.

How do you find a roof leak?

Finding the exact source of a roof leak can sometimes be difficult.

Water does not always enter the building directly underneath the visible ceiling stain. It can travel along roof timbers or other surfaces before appearing inside the property.

A basic inspection can include checking:

1. The loft or roof space for visible water damage.
2. The underside of the roof for damp areas.
3. Roof tiles or slates for obvious damage.
4. Flashing around chimneys and roof junctions.
5. Gutters and roof drainage.
6. Areas around skylights and other roof openings.

Do not climb onto a damaged or wet roof yourself. Roof inspections and repairs are safer when carried out by an appropriately equipped roofing professional.

Can a leaking roof be repaired?

In many cases, yes.

The appropriate repair depends on the cause and extent of the damage.

A minor problem may only require replacement of damaged tiles or repairs to flashing. More extensive damage may require roof restoration or replacement of a larger section.

Advance Roofing describes its roof restoration service as repairing areas affected by leaks, missing tiles and other roof problems.

When does a roof leak mean you need a new roof?

A leak does not automatically mean that the entire roof needs replacing.

A repair may be appropriate when the underlying roof remains in good condition and the problem is isolated.

Replacement may become more appropriate when:

• The roof has widespread damage.
• Problems continue despite previous repairs.
• The roof structure has deteriorated.
• Large areas of the covering are damaged.
• The roof has reached the end of its useful service life.
• Repairing multiple areas would no longer be economical.

The right decision should be based on the condition of the roof rather than the leak alone.

How urgent is a leaking roof?

A roof leak should generally be investigated promptly.

Water entering a property can cause progressively more damage if the source is not addressed. A small visible stain may represent a problem that has already affected another part of the roof structure.

If water is actively entering the property, particularly during heavy rain, consider contacting a roofing professional as soon as possible.

Advance Roofing states that it provides emergency call-out services for issues including storm damage and sudden leaks.

What should you do if your roof starts leaking?

If you discover an active leak:

1. Protect the inside of the property

Move furniture and belongings away from the affected area and use a suitable container to catch dripping water.

2. Look for obvious signs

If it is safe to do so, check the loft or accessible areas for signs of water entry.

3. Do not climb onto the roof

Wet or damaged roofing can be dangerous.

4. Arrange a professional inspection

A roofer can investigate the likely source and determine whether the problem requires a repair, restoration or replacement.

5. Deal with the problem promptly

Leaving a roof leak unresolved can allow further water damage to develop.
