What causes a leaky roof?

Age of the roof

As time goes by, roofs experience wear from constant exposure to the elements like sun and rain. This wear can lead to the materials breaking down, making the roof more prone to leaks. Even high-quality materials have a lifespan, and when they reach it, they no longer effectively keep water out.

Broken/Missing Slates or Tiles

Slates and tiles are crucial for protecting your home. They can break or be blown away due to strong winds, debris, or general wear, leaving areas exposed to water. These openings can allow water to penetrate the roof and cause damage inside your home.

Damaged Flashing

Flashing, the metal installed around roof intersections like chimneys and skylights, can degrade over time. This metal may corrode or come loose from the roof material, creating gaps that let water in. Keeping an eye on these areas is vital to prevent leaks.

Clogged Gutters

Gutters play a key role in directing water away from your roof. When they get clogged with leaves, twigs, or other debris, water can back up and seep under the roof materials, eventually leaking into your home. Regular gutter cleaning helps prevent this issue.

Roof Holes

Holes in the roof can result from various installations, such as satellite dishes which, if not properly sealed correctly after removal, leave spots for water to enter. These gaps need to be properly managed to avoid water damage.

Low-Sloping Roofs

Low-slope or flat roofs can collect water, especially if they have slates or tiles that are not suited for low slopes. This pooled water can find its way through the roof and cause leaks, making such designs more prone to water infiltration.

Issues with Skylights

Skylights brighten homes but can also lead to leaks if they aren’t installed correctly or if their seals become worn over time. Proper installation and maintenance are key to preventing leaks around skylights.

Cracked Roof Vents

Roof vents, made to ventilate attics, can crack or become brittle with age, especially those made from plastic. These cracks create potential points where water can leak into your home, so regular inspection is necessary to address any issues promptly.

How to Spot a Roof Leak

Indoor Inspection

Start by examining the inside of your house. Inspect the ceilings and walls for signs like:

  • Watermarks
  • Discolouration
  • Peeling paint
  • Bulges
  • Damp patches on the floor

If you find wet spots or hear a dripping sound, it suggests the need for a leaky roof repair.

Examine the Loft or Roof Space

Check the loft for signs of leaks, using good lighting. Pay attention to spots around chimneys, roof vents, and skylights. Look for:

  • Damp or darkened timbers
  • Pools of water
  • A musty odour

Mark any suspicious area with chalk. Measure its location from fixed points to help find it from outside.

External Examination

You don’t need to climb the roof. Use binoculars to inspect from the ground for:

  • Missing or damaged slates or tiles
  • Wear around chimneys and vents
  • Moss or algae growth

Check flashings around vent pipes, skylights, and chimneys for corrosion or breaks.

Water Test

If you can’t locate the leak, a water test can help. It requires two people: one on the roof with a garden hose and one inside the attic with a flashlight.

After dry weather, wet sections of the roof gradually. Let water run for a few minutes on each section. The person inside the attic should watch for signs of water. Remember, water may travel, so the source of the leak might not be directly above the visible water.

What to Do if You Have a Leaking Roof

Ensure Safety First

Before you do anything else, make sure the area is safe. Turn off electricity to avoid any mishaps with exposed wires. If the leak is severe, get a professional to look at it immediately.

Manage the Leak

Place a bucket under the drip to collect water. Lay down some towels to catch splashes. Move electronics, furniture, and other valuable items away from the area to protect them from water damage and prevent mould.

Provide a Quick Roof Patch

If it’s safe, you can temporarily patch the roof. Use a scraper or putty knife to apply the patch evenly over the leaking area. This will stop more water from coming in but remember it’s just a short-term fix. You will need a permanent solution soon.

Tip: If you are undertaking a leaky roof repair, try to do in on dry, sunny days for better safety and material adhesion.

Strengthen Your Fix

For maximum durability, apply roof patch tar over the patch. If you have an extra slate or tile or a piece of timber, press it into the tar. This creates a stronger barrier against water and helps keep your home safe from leaks.

By following these steps, you can manage a leaking roof and protect your belongings from damage. Always consider calling a professional for a more permanent solution.

How to Repair a Leaky Roof

Necessary Supplies for Roof Repairs:

To repair a leaky roof properly, you’ll need a few key materials and tools:

  • Roofing Nails: These nails are designed to hold roofing materials securely and resist weather effects.
  • Roofing Repointing: Pointing to seal any gaps, joints, and overlaps in roofing materials.
  • Replacement Slates or Tiles: Extra slates or tiles matching the existing roof to ensure seamless repairs.
  • Flashing: Thin, waterproof material to prevent water seepage and enhance roof longevity.

External Repairs:

Most roof damage appears on the exterior. Fixing these issues from the outside ensures a more lasting repair.

1. Swap Out Damaged Slates or Tiles

  • Check the roof to spot any damaged slates or tiles.
  • Use a pry bar to gently lift the damaged slates or tiles and the ones next to it to reveal the nails. Carefully remove the nails.
  • Slide a new slate or tile into place, ensuring it aligns with the adjacent ones.
  • Nail the new slate or tile securely with roofing nails, ensuring the nail heads lie flush.

2. Repointing

Clear away any old mortar before adding the new. This step is very important.

3. Fix the Flashing

  • Inspect the flashing for corrosion, bending, or dislodgement.
  • Remove damaged flashing and clean the area underneath.
  • Measure and cut a new piece of flashing to match the old one. Shape it appropriately.
  • Nail the new flashing into place and seal around the edges.

Internal Repairs:

Sometimes, it’s easier to make repairs from inside the house, especially for immediate fixes. Here’s how to address leaks from inside:

1. Find the Leak

  • Look for damp patches, mould, or water stains inside the attic or ceiling.
  • Mark the identified area to streamline the repair process.

2. Apply a Roof Patch

  • Make sure the marked area is cleared of any debris.
  • Position a roof patch over the leak from the inside, ensuring it extends a few inches beyond the damaged area.

3. Seal the Area

  • Ensure the area is dry and clean before applying sealant.
  • Make sure the edges are sealed well to prevent future leaks.

By following these steps, you can address both external and internal aspects of a leaky roof, ensuring your home remains dry and protected. If in doubt, consult a roofing professional at Premier Roofing Solutions to guarantee the best results.

How to Prevent Future Roof Leaks

Routine Roof Checks

Inspect your roof twice a year, ideally in spring and autumn. Look for any signs of damage, such as missing or broken slates or tiles, and other potential problem areas. Addressing these issues early can prevent them from becoming major problems.

Keep Gutters Clean

Regularly clean your gutters and downspouts to ensure water flows properly away from your home. Blocked gutters can cause water to back up and increase the chance of leaks.

Prompt Slate/Tile and Flashing Replacement

Replace worn-out or damaged slates or tiles and flashings right away. It’s more manageable to replace a few now than to deal with a leak later. Keeping up with these small repairs can save you a lot of trouble.

Ensure Proper Ventilation

Make sure your attic is well-ventilated. Good ventilation can help prevent the formation of ice dams, which are a common source of roof leaks in winter.

Seal Leak-Prone Areas

Use a quality sealant to secure areas that are prone to leaks, such as roof valleys, chimney bases, and around skylights. This can be a simple yet effective way to prevent water from getting inside.

Trim Back Overhanging Branches

Trim branches that hang over your roof. These branches can drop leaves that clog your gutters or break and damage your roof. Regular trimming helps keep your roof in good condition and reduces the risk of leaks.


Addressing a leaky roof repair promptly is essential to prevent further damage to your home. By understanding the causes of leaks and knowing the steps for effective repair, you can safeguard your home.

Whether it’s replacing damaged slates or tiles, sealing gaps, or patching holes, each method helps protect and enhance the longevity of your roof. In all cases, safety is crucial, and if you are unsure, seeking professional help is always recommended.
