8 Common Causes of Roof Leakage

If you are an owner of a home that has experienced roof leakage, you know the frustration and devastation it can cause. Roof leakage is not only inconvenient to deal with but also expensive. This blog post will discuss 8 common causes of roof leaks and what you should do if they happen to your home.

1. Old Roofs

An old roof is a common cause of leakage. As your roof ages, it loses the ability to withstand weathering and other environmental factors such as insects or falling branches. These issues can lead to structural damage that will need to be repaired before long. If you do not have any signs of leaks yet but have a more than 20 years old roof, you might think about replacing the roof before it becomes necessary.

2. Wind Damage or Pressure

Wind can blow your shingles off the roof and weaken them against other weather conditions such as heat from the sun. If they don’t have enough support to keep going, then this will cause leaks! This means that if there was a mighty storm in your area recently, be sure to check for any damage on top of your house and see what steps need to be taken next.

On the same note, pressure from heavy snowfall could also cause leaks by piling up too much weight onto one side of a section or damaging certain areas with extremely cold temperatures. It’s important to remove this snow as soon as possible to avoid any leaks.

3. Leaking gutters and downspouts 

Gutters and downspouts are essential parts of a roof that help to direct water away from home. When they leak, it causes problems with the shingles at your house. Make sure you have both gutters and downspouts inspected every year to keep them running smoothly.

4. Extreme weather conditions (too hot or too cold)

If your roof is exposed to extreme temperatures, it can weaken the structure and cause leaks. In terms of being too cold, you could have ice dams that form in freezing rain, which accumulate around the edges where they freeze to create a dam. This leaves water behind when thawed out and will eventually lead to a leak as well!

For temperature-related issues with roofs, one way to eliminate this problem is by installing insulation on top of the roof under shingles before they start leaking. You should also check for any holes that might be allowing more heat into the attic through its vents so that you can seal these spaces as well.

5. Homeowner neglect or improper installation of roofing materials

If your house has been neglected for a long time, you may find that leaks are coming from the rafters because they have rotted out over time. If these types of repairs haven’t been done in some time, it’s likely to lead to water seeping through the roof, which can cause leaking problems.

One sign might be broken shingles on top, while others include screws missing around vent openings along with open seams! You will want someone who specialises in waterproofing to come and do an inspection before any major problem arises so that you don’t get too much water inside your home where mould could grow!

6. Animal intrusion

Suppose an animal is living inside a home (such as mice). In that case, they can cause structural damage by chewing on wood beams, weakening them against other environmental factors related to rainwater, etcetera.

This means that if there are signs of rodents around your house, such as faeces near vents, droppings in crawlspaces, or food left behind, you might have another issue with leaking roofs coming up soon! You’ll want to call professionals specialising in eradicating pests because this could lead to structural damage and other problems.

7. Patchy roofing materials or a poor-quality installation

If shingles are missing, it can create leaks that will eventually lead to bigger problems. If your house has been neglected for many years, then you may need new ones installed! Some signs of this include if the ridge vents have pulled away from the trusses and holes in the roof deck, which should be repaired as soon as possible.

It’s also important to know how well your current roof is performing because older roofs tend to have more problems with leaking than newer models do. The reason why this might happen could be due to improper installation when they were first laid down on top – so make sure any future roofer who installs them knows what they’re doing before they do the job!

8. Shingle nails not seated correctly in the shingle tabs 

Shingles have tabs that are meant to hold them on the roof. If shingles nails aren’t correctly seated under these tabs, water will seep between the nail and tab, causing a leak in your roof. You’ll need to remove all of the loose nails before securely seating them around their respective tabs to fix this issue.


In conclusion, there are a variety of reasons why roof leakage can happen. It is essential to know that these types of problems should be addressed as soon as they arise so that more serious issues occur to avoid any significant water leakages inside your home.
