How To Fix A Leaking Conservatory Roof

With a conservatory, you may bask in the sun’s warmth even when the temperature drops outside. 

Yet, as with any other part of your home, issues occasionally develop. Stormy weather usually means one thing: a leaking conservatory roof. When that occurs, you may begin to worry about the state of your conservatory and wonder, is it possible to fix a conservatory roof leak?

Weather conditions are irrelevant regarding the inconvenient presence of a leaking conservatory roof. A variety of factors can bring on leaks. The good news is that there are ways to fix the leaking conservatory roof. This post will explain how to find the source of a leak in the roof of your conservatory and fix it.

Let’s dive in.

How to Fix A Leaking Conservatory Roof: Effective Strategies

Short-Term Fix 

The immediate fix to the leaking conservatory roof is waiting for the rain to stop so that you can safely climb onto the roof and fill the hole with sealant. A sliding panel may require realignment and reseal on a polycarbonate roof. 

Remove the affected roof panels, wash and dry them, and then apply a silicone bead around each edge. After that, replace them. Accessing the top of the roof is necessary for this, and if you are not confident in your abilities to do so securely, you should seek professional help. 

While it may stop the conservatory roof leak problem, for the time being, there’s no guarantee that another spot on your conservatory roof won’t develop a leak in the future, which is why this is only a temporary fix.

However, if the roof of your conservatory is built of glass, fixing the leak may be more difficult. As with polycarbonate, glass panels include a frame and a material, but the weight of glass makes it a less popular option. 

Only two individuals and some tools can safely remove the glass. Damage to the panel during removal may necessitate a replacement, which will likely be very costly.

Long-Term Fix

Roofing replacement is something that needs to be thought about in the future. Afraid you won’t have the stamina to follow through? To your surprise, it could be quite easy.

When you call an expert service provider for your leaking conservatory roof, they’ll take care of everything. This includes scheduling the initial consultation at a convenient time to having a sales representative come out and collect measurements so that you may have your panels custom-painted in a colour scheme of your choosing. 

Professional installation of your panels will take just one day, thanks to the helpful team of experts. The insulated roofing panels will leave no crevices for condensation to collect, reducing the likelihood of mould growth and improving your roof health in the long run. You can stop worrying about fixing the roof from the ground.

Why is My Conservatory Roof Leaking?

Below are some common reasons why you are facing conservatory roof leak problems.

Cracks in the Glass

The glass on the top of the conservatory is vulnerable to breakage from accidents, heat stress, and other environmental variables. When the roof of your conservatory begins to leak, it can spread the problem of moisture and mould throughout your home. 

Lightweight metal tiles are a good option for a conservatory roof since they are sturdy and won’t rust, but no roofing material can be guaranteed to endure forever. Regardless of the material you choose for your conservatory roof, it will require regular upkeep to ensure it lasts as long as possible in pristine condition.

Cracks in the Glass

Broken or Damaged Sealant on the Conservatory Roof

This is a common reason for roof leaks in conservatories. The sealant used on the conservatory’s roof should keep the elements out completely. However, it is possible for this layer to deteriorate over time due to things like improper installation or normal wear and tear.

Broken or Damaged Sealant


A conservatory roof leak problem may also be caused by guttering that has become defective owing to cracks or simple wear and tear. In this case, your conservatory roof is unfortunate but unavoidable collateral damage. Cleaning and repairing your gutters thoroughly is the best option.


Perhaps the conservatory roof leak problem results from improper flashing in the conservatory. If the damage is too serious about being fixed, it will have to be replaced. If it does not, ensure all the seams are sealed and clean.

How Much Does It Cost To Fix A Conservatory Roof Leak?

If a sliding panel is to blame for the conservatory roof leak problem, fixing it won’t save you money.

If the problem persists, you may need to install brand-new roof vents or another component of the conservatory roof. The final price tag will be determined by the manufacturer and type of material you want, as well as any additional labour expenses.

If the worst should happen:

The typical cost to replace a conservatory roof ranges from £6,300 to a whopping £22,500. Though, this may vary greatly based on the size and substance of your current roof. 

It’s a big bill, which is just one more reason to look for signs of a leaking conservatory roof as soon as possible and replace it as soon as possible.


Do I Need To Replace My Conservatory Roof?

The damage’s extent will determine whether you can repair the roof without replacing the entire conservatory structure. It’s fairly uncommon for only a couple of parts to need replacing if you catch the leaking conservatory roof problem early on. There is no longer much of a need for a professional roofer to come out and change things like flashing, vents, or polycarbonate sheets, all thanks to technological advancements in the roofing industry. However, if the roof of your conservatory is leaking, it could indicate deeper structural issues.

Can I Fix A Conservatory Roof Leak Myself?

While a complete roof replacement for a conservatory is not something we recommend for a homeowner or DIY novice to take on, many of the problems that cause leaks can be addressed quickly and easily by just about anyone. Most leaking conservatory roofs can be fixed by replacing a single roof panel or vent or by reapplying sealant. You should always prioritise safety if you’re doing any kind of work around the house.

Is Wear And Tear Covered Under Buildings Insurance?

Inform your insurance company if you plan to build a leaking conservatory roof. If you have, then any unforeseen damage, like a leaking roof, will be covered by your policy.

However, a word of warning; may not necessarily be the case if the leak results from normal, age-related wear and tear. Never delay in informing your insurer of damage, even if you think it might be covered.
