Here’s 18 Reasons As To Why It Could Be!

Faulty Or Damaged Flashing

A reason for leaks could be the use of poor installation practises during construction; improper flashing installation means water will eventually find its way into your home through small gaps in your roof’s protection system where there should never be any holes at all!

What is flashing? Flashing is a small piece of metal that is used to seal the gap between the roof and wall. Flashing can become damaged or missing, which thus allows water to seep into your home.

Aged Roofing Materials

One of the most common reasons for a roof leak is old, deteriorated or damaged materials. The roof of your home is one of the most important aspects of it and its longevity depends on how well you maintain it. Extreme temperatures over time, as well as severe weather such as rain, snow and hail can damage your roofing materials.

If your roof is exposed to these elements over an extended period of time, they can begin to deteriorate or break down which will then lead to issues down the line.

There are various factors to consider when looking at the cause of a rook leak, including old or damaged materials such as shingles or flashings (the metal foil that covers joints between two pieces of shingles.)

Damaged Roofing Membranes Or Underlay

Roofing membranes are the primary layer of protection for your roof. They are installed to protect the roofing materials from the elements, and they also serve as a barrier between your home and water damage.

To protect against weathering effects, such as wind-blown rain or heavy snow loads, Underlayment is sometimes used instead of a membrane.

If either of these components are damaged or torn in any way, they can leave your roof vulnerable to leaks and damage that could turn into bigger problems down the line.

Broken Or Missing Roofing Tiles/Slates

A leaky roof can be a big problem, as they can cause damage to the interior of your property and even, potentially lead to further problems if left untreated. It’s therefore very important to check for broken slates or tiles on your roof. If you noticed that any of your slates or tiles are broken it is advisable to have them replaced immediately by an expert roofer.

The easiest way to check if any tiles are missing from your roof is by looking at it from ground level. If you cannot see any gaps in between the slates then this is an indication that everything is intact and there are no missing items on the surface of your home’s exterior walls.

Poorly Placed Fixings

On some instances, it’s the fixings themselves that are to blame. Roof tiles and slates are laid on top of a framework of wooden battens, which are then fixed to the roof with screws or nails. If the fixings aren’t placed correctly – for example, if they’re not entered over the tile/slate or if there are one too many holes around the edge – they can cause water to leak into your home. To stop this from happening:

• Make sure all the screws and nails are driven into the batten at least 1″ from where it meets other pieces of wood (the closer you get to an edge, the higher risk there is for leakage.)
• Use a pair of pliers to fix any damaged parts carefully and seal any holes left bending with silicone caulk before re-fixing.

Condensation In Your Loft Space

Interstitial condensation and surface condensation were the two types of condensation which could be found in your loft space.

Condensation is usually caused by high humidity, which can be caused by a number of different factors. The first factor could be the installation of an under-ventilated roof system. This means that there could be gaps or voids in your attic insulation that allow for moisture to build up and cause problems. We suggest that if you think this could the cause with your attic, that you contact a roof expert as soon as possible!

Lack of airflow is another reason for condensation. Or, air exchange in your home’s ventilation system. To remedy this problem, you’ll need to install adequate roof ventilation; otherwise, your house will retain moisture and could become mouldy.

Poorly Installed Skylights Or Roof Windows

The poor installation of Roof Skylights or Windows is a common reason as to why a roof leaks.

Clogged Gutters

If you have gutters attached to your home, you should make sure to clean them regularly. The best time to clean them is before leaves start falling in the fall and after heavy rains or storms.

When leaves land in your gutter, they can become stuck in there, causing water to pool and leak into the house instead of draining away from it through the downspout.

Cracked Chimney

If your home is old, there is a high chance that your chimney may have never been cleaned. Due to this, your chimney may be filled with years of creosote and other debris that could have built up over the years. This could result in condensation forming within the flue structure itself, leading to leaks in roofing materials and ceilings below.

To avoid this, make sure that your chimney is being swept regularly so that all of this debris can be removed from inside and make sure to have your chimney inspected annually by a professional so that they can make sure there aren’t any cracks or structural issues emerging.

Ice Damming

You may be wondering what Ice Damming is, well, it’s when snow on your roof melts due to the warmth of the house below and then refreezes as it reaches the edges. As more snow melts and refreezes, an ice dam can form. This can enable water to seep into your attic and leak through ceiling tiles or walls. Luckily, there are a few things you can do to prevent ice dams:

• Drag snow off of your roof using a roof rake before it turns into an icicle-filled mess that could damage your home’s exterior or interior structure by breaking off during windy conditions.
• Inspect your gutters regularly and clear them if they’re clogged with debris like leaves or pine needles.

Damaged Roof Vents

Roof Vents are vital to your home’s structural longevity. Venting allows air to flow in and out of your home so that no moisture gets trapped and causes damage. If you spot any cracks in your roof vents, it’s vital that you begin the repair process!

Damaged Soffit or Fascia Boards

One of the most common ways for damage to occur is through Soffit or Fascia Boards. These boards run along the edge of your roof and are typically made from wood, aluminium or vinyl. They’re used to protect walls from rainwater leaks as well as insulation from melting during extreme heat or cold conditions such as those experienced in the winter months.

These boards, however, are often damaged by high winds during storms or ice buildups during freezing temperatures in the winter months.

Working On Your Roof

Never work on a roof when it’s wet or raining, this in order to avoid roof leaks. It is also advised to make sure that the ladder you are using is stable and tall enough for the job. There are other safety measures that you should take as well:

• Don’t stand on top of your ladder.
• Don’t use an aluminium ladder on a metal roof because they don’t conduct electricity like wood ladders do.

Wildlife

Most Birds, Squirrels and Racoons can be harmless to your roof. However, if they find a way to settle on the roof for a long time, they can unintentionally cause damage. If you’re vigilant enough to keep them off, then this shouldn’t be an issue.

You could use netting or a netting-type material around the perimeter of your home so that when they get up high enough on the side of a house they’ll fall back down before making it over to the roof line. You might have success with this method alone in preventing wildlife from getting up there in the first place!

Overhanging Trees

Overhanging Trees can unfortunately cause significant damage to your roof. This can include structural damage to your roof, damage to the insulation, and even damage to your roofing materials.

It could also result in you having to replace any other parts of your home that were damaged because of this leak, such as gutters or fascia boards.

Lean-To Roof

If your roof is sloping on one side only and not the other, then its a lean-to roof. These types of roofs are often used to extend the living space of a property or house by creating an extension. They’re also useful for creating an independent living space n the ground floor of your property such as an additional bathroom or bedroom.

It’s vital, however, to keep a close eye as this is where your main roof often sheds rainwater. If this continues, it can increase the moisture levels and overtime, can compromise the integrity, eventually leading to a leak via the roofing material or its underlay.

Punctures or Pooling Water

A puncture in your roof could be allowing water to seep through, if this is the case, you will see water pooling on your ceiling or inside of your attic.

You could even have a puncture in one of your skylights, which will cause water to leak through the roof when it rains.

Finally, a leaking chimney flashing could be causing leaks in your home’s ceiling.

How To Identify A Leak In Your Flat Roof

If you suspect that you may have a Leaky Flat Roof, prompt inspection and identification of the leak is vital. To effectively identify a leak, follow these guidelines:

• Before beginning your inspection, await a dry spell of up to 72 hours. Climbing up onto your roof during cooler temperatures may enhance visibility of any leak source.
• If you have any doubts about carrying out the inspection yourself, whether it be due to the climb up onto the roof, always prioritise safety and do not hesitate to contact a professional.
• If you see any steam during your examination, this may be an indication of heat escaping from a breach in your roof.
• Dirt Rings or Water Stains could reveal previous water pooling locations, which are often responsible for leaks.
• To make it easier to pinpoint the area of the leak, irrigate the suspected area with a hosepipe and observe if water appears inside.

Keep these points in my mind when inspecting your roof:

• The Common Causes of Roof Damage: look for things such as a slits, punctures, or degraded seals, which could all lead to leaks.
• If the area you irrigated with the hosepipe does not reveal a leak, attempt the irrigation again in various locations until the leak is located.
• Have a look! Whilst inspecting your roof, survey for any other potential issues that may cause future leaks.

By following these steps you can often detect the exact point of a leaky flat roof without the need for extensive professional intervention. However, keep in mind, that if the flat roof repair is beyond your skillset, enlisting a skilled roofer is always recommended to ensure a lasting resolution.

How To Fix Leakages In Flat Roofs

Resolving A Leaking Felt Roof:

Leaks and divisions in felt roofs can typically be fixed by using a dual layer of flat roof sealant after ensuring the area in question is clean and completely dry. For significant damage, we would recommend adding new layer of torch-on roofing felt, but if you’re not certified to work with open flames, it is important to seek help from a qualified professional.

Fixing Splits in Fibreglass Roofs:

Known for their longevity and visual appeal, Glass Reinforced Polyester (GRP) Roof’s are perfect options for your property, but what do you do if you have to mend a split? Buy a good-quality Fibreglass Repair Kit, then prepare the area in question with sandpaper and acetone. Follow the kit’s instructions to apply chopped strand matting and finish off with a top layer. When resolving flashing problems, always make sure to ensure matching colours for a seamless finish.

Patch an EPDM Roof:

Being a durable choice for Flat Roofs, Ethylene Propylene Diene Monomer, or EPDM, is a cost-effective and eco-friendly choice for your property. And patching one isn’t difficult. You can use EPDM sealant for small tears, but larger holes may require a more lasting approach. Once you have cleansed the area, apply an EPDM-specific primer and then fix the area with self-adhesive flashing tape, making sure to work from the centre outwards. Using a roller can help ensure it’s firmly in place, capped with edge sealant for added assurance.

Cracks in Concrete Roofs:

You can apply a bitumen primer followed by a waterproof sealant or paint for a temporary fix for a crack in a concrete roof. For larger cracks, bonding a new layer of roofing felt is optimal, torch-on if the crack’s size warrants it. Remember, working with an open-flame requires proper insurance.

Sealing An Asphalt Roof:

Remember to examine your asphalt roof for blisters and ruptures. For a quick solution post-cleaning, we recommend using a self-adhesive bitumen flashing tape. For more extensive damage, consider using a torch-on roofing felt for a more resilient option. This technique also applies to multiple cracks or blisters grouped together. Ensure you, or the person conducting the repair, are insured to manage open flames.
