How to Repair a Leaky Roof

A leaking roof can be an incredibly annoying occurrence within any home, but any water that makes its way into your home through a crack in the roof could actually do a lot of damage.

Your home is supposed to be impervious to all weather types, so the moment it stops being so you’ll know there’s something wrong.

What Damage Can a Leaky Roof Do?

You’d be surprised just how damaging this kind of fault can be, which is why it’s so important to get it fixed ASAP.

According to an article on Service Magic, it can cost between £4,000 and £20,000 to replace the roof on an average detached house. It all depends on how much work needs to be done, the materials used and the size of your property.

Unwanted water within a home can quickly lead to damp. Care2 explains that damp surroundings can invite in a whole host of bacteria, along with pests such as cockroaches and mice that can be difficult to get rid of. Dust mites also love damp and warm environments, so their numbers can increase when you have a leaky roof. Most harmful of all though can be the resulting mould caused by damp.

Mould can produce a number of side-effects and is especially harmful to children that are still developing. It can cause asthma, hayfever, croup and even COPD (Chronic Obstructive Pulmonary Disease).

So Why is My Roof Leaking?

Unfortunately, this question isn’t all that easy to answer without examining your roof. There could be many reasons for your leaky roof, and it isn’t always as easy as assuming that the source of the leak (i.e. the hole in your roof) is right above where the water is coming out.

When water enters your home it can run down the roof’s slope, through wall cavities and over insulation before it emerges inside your house. The best way to find out why your roof is leaking then is to do a spot check of all possible causes.

How to Find a Leak

When looking for the source of your leaky roof, you will need to check the main culprits for this kind of issue. These can include:

  1. The seals around air vents and pipes
  2. The flashing (the metal placed around the chimney and other parts of the roof to make it waterproof)
  3. Shingles (the individual tiles used to roof a house)
  4. Gutters and waterspouts
  5. The dormer valley (where the dormer meets the main part of the roof)


Blocked gutters, broken seals, flashing and cracked shingles can be some of the main causes of leaky roofs.

What to Do When You Find the Cause

Often, the best way to fix a leak is to repair the fault, after which you can focus on fixing any internal damage to the property.

This can involve replacing shingling, clearing gutters and re-flashing the roof to reinstate its waterproof properties. If you find that there are a number of potential causes for your leaky roof, you would be better off having all of them repaired. The last thing you want is to only repair the root cause of your leaky roof and then have a second leak appear just a few weeks later.

How to Repair the Internal Damage

If you’ve managed to catch the leak early enough, you may not notice any internal damage such as damp patches or mould. However, those that haven’t been this lucky will need to focus on getting rid of these resulting issues.

The main issue will be the build-up of moisture within your property. In this case, simple techniques such as opening a window or using a dehumidifier to get rid of excess moisture in the room can help.

Can I Do This Myself?

While it’s certainly possible for anyone to have a go at repairing their own roof, it can sometimes be better to let a professional do the job.

If you have no idea what you’re doing when it comes to fixing your roof you could actually end up doing more harm than good. By hiring a professional you can ensure that the job gets done properly, so you won’t need to be up on your roof again anytime soon.

A leaky roof can cause a lot more damage than you might expect, so you should take action before the problem gets out of hand.
