How to Stop Roof Leaks

What are the most common causes of roof leaks?

A roof leak seldom starts with a single event. Most of the time, a series of small things happens without us knowing, and the next thing you notice is the damage it is doing.

• Damaged tiles
  • Wind, storms, age, or people walking on the roof can break or shift tiles.
  • Moss, algae, or lichen hold water against tiles, causing damage and gaps.
  • Water first soaks the underlay, then may rot timbers; the first sign is often a damp ceiling patch.
• Broken or worn flashings
  • Flashings around chimneys, vents, gables, etc., can rust, harden, or get damaged by weather or animals.
  • Leaks from flashings can show on ceilings or run down walls.
• Blocked gutters
  • Overflowing gutters can spill down walls or force water back under the tiles and into walls.
• Ridge tiles and mortar
  • Cracks from wind, the building settling, or sun damage will let water in.
  • Water may run down inside the roof before appearing on the ceiling, making the source hard to find.
• Flat or low-pitched roofs
  • Waterproof membranes (EDPM, polyurethane, bitumen) wear out, harden, blister, or shrink over time.
  • Pooling water or blocked gutters (leaves, moss, debris) can find cracks or joints to leak through.

Why should you inspect your roof regularly?

By now, you should realise that one does not always see these problems and often only becomes aware of them when some damage has already been done.

That makes it very important to inspect your roof regularly. Roofing specialists from Improve A Roof are trained to spot them long before you can and will save you a lot of money in the long term by preventing structural damage and expensive repairs.

What are the first warning signs of a leaking roof?

If you don’t get your roof checked often, the first signs of a problem are usually:

• Damp patches, yellow stains, or brown streaks on ceilings and upper walls.
• Paint peeling, bubbling, or going powdery, oily, or soapy.
• Bubbling or stained wallpaper.
• A musty smell from trapped water in walls, attics, or stored items.
• Green fuzzy patches (mould or mildew).
• Water dripping from the ceiling or running down the walls.
• “Puffy” patches on the ceiling.

You’re more at risk if your area gets lots of rain, has long damp periods, or if tree branches, birds, or small animals hang around your roof. Not having regular professional roof inspections and cleaning also increases the chance of leaks.

Don’t ignore these signs. Early problems are usually cheaper and easier to fix. Waiting will make the repairs cost much more.

What should you do if you notice signs of a roof leak?

Severe leaks:

Call a professional roofer immediately if there is a severe leak or a sagging ceiling.

Do not climb onto the wet roof to try to fix it during the downpour.

• The risk of injury is simply too high.
• If there is a weak spot on the roof, you might cause further damage or even have a partial collapse.
• Electrical wires might be exposed to water, and you could be electrocuted.
• With water pouring from the ceiling, you need to restrict the damage by moving furniture, rugs, and loose carpets out of the way.
• Place buckets under the drips to protect your flooring, and spread towels to absorb the water and prevent it from flowing into adjacent areas.
• Protect furniture from water damage by covering it with a tarpaulin or plastic.
• If the ceiling starts sagging, poke a hole to let the water run out freely and prevent the ceiling from collapsing.

What are the main steps in protecting your roof from leaks?

Preventing big roof problems means staying alert and using professionals for regular checks, cleaning, and small repairs.

•  Leak repairs

We will fix all leaks and replace broken tiles or flashings.

If you want, we can treat the tiles to slow ageing, or we can apply a thermal sealing coat to improve insulation and refresh the look of your roof.

• Flat or low-pitched roofs

We can install a Firestone EDPM rubber membrane for long-lasting waterproofing.

When is the best time to have your roof inspected?

• Have your roof checked by a professional at least once a year. If you have heavy rain, damp conditions, or overhanging trees, get it checked every six months. The best times are before and after winter.
• Regular checks and maintenance stop leaks, avoid damage, and save on costly repairs.
• Get your roof professionally cleaned every 2–3 years to remove moss, algae, and debris so water drains properly and tiles stay dry.
• Consider a protective coating or waterproof sealant for extra peace of mind — the best can last 10–20 years and help keep your roof watertight and looking good.
• If you have a flat or low-pitched roof, make sure the waterproof membrane is inspected too.
