This means that if you own a pitched roof you should consider being aware of the five common pitched roofing problems so that you can be conscious of when they happen and how you can avoid them occurring as quickly with your own pitched roof helping you save money and stress in the process.

The five most common pitched roofing problems include:

  1. Broken flashing
  2. Pitched roofing leaks
  3. Moss & algae growth
  4. Poor installation
  5. Broken slates or tiles

1. Broken flashing

One of the most common problems that we often come across with pitched roofs in the UK is broken or damaged flashing. Flashing is used on the majority of roofs to prevent water from getting into the property. Flashing is mostly prominent in areas where the roof is more susceptible to water leakage such as around skylights, windows, chimneys and filtration systems. Over time this flashing can get worn away and start to deteriorate, this can also be sped up with bad weather conditions too where the flashing can become ripped. 

How to avoid problems with broken flashing

In a way to try and prevent this issue from occurring or getting too serious of a problem, ensure that you regularly perform maintenance checks on your roof flashing, especially after a major storm or spell of bad weather. If you do notice that your pitched roof flashing is damaged in any way, please get in contact with a qualified roofer who will be able to easily amend the issue reducing any further risk of damage to your roof, property or belongings in your home. 

2. Pitched roofing leaks

A leaking roof is a common issue that occurs across all types however the type of leak can differ for each type of roof. For example, a pitched roof will face water damage issues such as drainage problems and leaks from certain weak points on the roof. If drainage pathways are not kept clear on the pitched roof, debris can build up causing blockages meaning excess water can start to leak into your home. Heavy rain can also damage shingles and flashing making vulnerable hot spots for water leaks.

How to avoid problems with leaks

In order to avoid problems with pitched roofing leaks is ensure that you are proactive in unblocking and removing any debris or rubbish that has ended up on your roof. This can be something you can do yourself, easily unblocking gutters and removing loose objectives off the top of your roof. By getting into a habit of clearing debris off your roof, you will reduce the risk of drainage and roof leaks significantly. 

3. Moss & algae growth

Living in the UK, the weather conditions typically make it the optimal conditions for moss and algae growth on top of your pitched roof. Moss and algae can become a serious issue when it comes to your roof, firstly moss has a sponge-like texture resulting in it being able to absorb and retain water. This is a problem for your roof as prolonged moisture exposure can lead to the degradation of your roof over time. Furthermore, as the moss and algae spread along your roof it can start to grow in between your roof tiles and shingles, loosening them and damaging them. This can weaken your roof and allow water to penetrate into the property itself.

How to avoid problems with moss & algae growth

Moss and algae growth is fairly easy to treat by using zinc or copper strips. All you need to do is place a 2-inch thick strip of copper across the ridge of your roof as near to the pitch as you can. This will then protect the roof from moss and algae growth.

4. Poor installation

Whether you have bought a new build or have bought a previously owned house, the quality of your pitched roof is totally dependent on the people who installed it previously. Therefore, if the roof was not installed by a qualified, trusted roofing contractor and the person who installed your roof previously cut corners and rushed the process, it can lead to major issues down the line.

How to avoid problems with poor installation
