The Hidden Dangers of DIY Roof Repairs
DIY projects have become increasingly popular in recent years, especially since lockdown. Many homeowners are keen to save money and take on home improvements themselves. While some projects are perfectly manageable, roofing work is very different. Your roof protects your entire property from the elements, and mistakes can lead to serious structural damage, leaks and safety risks.
DIY projects are growing in popularity since lockdown – people are more inclined to save money and have a go at jobs themselves. However, getting up on a roof may be a job which is best left to professionals with the knowledge to get it done correctly. If you decide you are going to have a go yourself anyway, these are some common hazards that you should look out for:
Before climbing a ladder, it is important to understand the potential risks involved in carrying out roofing work without professional training or experience.
Causing A Leak
If you install certain roofing elements incorrectly, you might end up making your roof ineffective. Nailing in asphalt shingles might look like a straightforward task, but you will need to carefully install underlayment and flashing if you want a leak-free functional roof. It is quite easy to leave gaps, holes, and other errors which can end up being a major headache later on down the line.
Even small installation mistakes can allow water to penetrate beneath the surface of your roof. Once moisture reaches the roof timbers or insulation, it can cause rot, mould and long-term structural damage. Improperly fitted flashing around chimneys, skylights or roof valleys is one of the most common causes of leaks.
If you are unsure about flashing or tile installation, it is always safer to consult experienced professionals in roof repairs before small issues turn into costly damage.
Injuring Yourself
This might be the biggest hazard when getting up on your roof. You might get yourself in some dangerous situations whilst up there. If you do not feel comfortable with heights or walking on sloped surfaces, then roof work will not be for you. Watch out for the following to avoid getting injured:
- Using the tools incorrectly
- Falling through weak parts of your roof
- Losing awareness of the edge
- Slipping on a steep pitch
These issues are particularly dangerous if you own a two-storey house. Even good quality personal protective equipment does not offer enough protection against falls, improper use of nail guns and other hazards.
Professional roofers are trained to work safely at height and use specialist equipment designed for stability and fall prevention. Roofing surfaces can become slippery very quickly, especially in the damp and windy conditions common in North Wales.
Your Warranty
If you end up causing damage to your roof whilst you are trying to repair it yourself, it is possible that you may void the manufacturer’s warranty on it. This is not a risk you would want to take, but professional roofers know how to deal with this, it is their job after all.
Many roofing systems and materials come with manufacturer guarantees that are only valid when installed by qualified professionals. Incorrect installation can invalidate these warranties, leaving you responsible for future repair costs.
Additional Expenses
In the end, a lot of people find that they end up spending more when trying a DIY roofing project. From the amount of time you spend on the roof, to the amount of money you spend on materials needed to fix things. It might be worth it to call a professional instead – save your weekends and time after work for relaxing or having a go at another, more manageable DIY project!
DIY repairs often require purchasing tools and materials that may only be used once. If mistakes are made, correcting them can cost significantly more than hiring professionals from the start. In some cases, partial DIY work can make future repairs more complicated.
