Can you replace the tiles on a foam insulated roof?

Spray foam insulation bonds the tiles on your roof together, but replacing a damaged tile is still simple enough when you know how.

When spray foam is applied to the underside of a property’s roof it bonds the roofing materials to each other and to the structural timber, holding everything securely in place.

As well as sealing all gaps and cracks in the roof to make the property warmer and more energy-efficient, spray foam can also help to protect and support your roof’s structure and increase its lifespan.

Whilst spray foam will make your roof stronger and more durable, it won’t make it invincible and it is still possible that tiles on your roof may become damaged.

If a tile on your foam insulated roof cracks or breaks then don’t worry, replacing it may be simpler than you think.

Removing a tile on a spray foam insulated roof

If a tile on your roof becomes broken, then it’s important to get it repaired as quickly as possible to prevent water leaking into your property and causing expensive damage.

To remove one or more tiles from a spray foam insulated roof you are likely to need to remove the insulation first.

You may wish to begin by using a saw or utility knife to cut away the majority of the foam that you need to remove. With the bulk of the foam gone, you should be able to scrub away the rest with a strong wire brush or sponge. It may help to apply a small amount of acetone before you scrub the foam to help to loosen the bond.

Once the foam has been removed, the broken tile can be replaced, and the spray foam will need to be restored to ensure that the insulation keeps working efficiently.

Benefits of spray foam insulation for historic or listed buildings

Spray foam insulation is an ideal solution for securing tiles on the roofs of listed and historic buildings.

Spray foam insulation is applied to the underside of roofs to bond slates and tiles together, providing effective insulation and structural support.

Whilst spray foam insulation can benefit buildings of all different shapes, sizes and ages, it can be particularly useful for securing tiles on the roofs of historic or listed buildings, here’s why:

Preserve appearance

It is very important to preserve the appearance and original character of historic and listed buildings by retaining original features and materials where possible. Securing and sealing the existing roof with spray foam can help to bond the existing roof and tiles together to cure nail fatigue and avoid the need to replace roofing materials.

Protect roof tiles against theft

Very old and listed buildings are also more likely to have valuable tiles on their roofs, including lead tiles, which are frequently targeted by thieves.

Bonding your roof’s tiles together and to the roof’s structure using spray foam will help to protect valuable roof tiles from being stolen.

Further benefits of spray foam insulation

As well as protecting and preserving the outer appearance of historic and listed buildings, spray foam insulation provides a whole host of other benefits including:

Affordable solution to re-roofing.
Makes the roof weather-resistant.
Seals the roof to get rid of air leaks and draughts.
Improves the building’s energy efficiency.
Keeps the building feeling warm and comfortable.
Prevents condensation build-up.
Reduces the risk of pipes and tanks freezing.

The spray foam we install at Metropolitan Insulation prevents interstitial condensation, whilst also allowing the roof’s battens to ‘breathe’. It also meets Class 1 Surface Spread of Flame when tested to BS 476 Part 7:1997.

Does vermiculate insulation contain asbestos?

Should you be concerned if you have vermiculate insulation in your roof?

Vermiculate insulation is commonly used to insulate building roofs and walls. If you have vermiculate insulation in your home, you may be concerned by reports that some vermiculate can contain asbestos.

If your vermiculate insulation was installed after 1990 then you’ll be relieved to know that it is unlikely to contain asbestos. There is however a chance that older vermiculate insulation could be contaminated with the dangerous substance.

What is vermiculate?

Vermiculate is a natural material that expands when it is heated, making it ideal for insulation. It is flaky material that looks a little like grey, lightweight gravel.

Vermiculate and asbestos

In its natural form, vermiculate is not dangerous and does not contain asbestos. However, prior to the 1990s, most vermiculate originated from one mine in America which was contaminated with asbestos, later causing problems for over 35 million homeowners in the USA.

Unfortunately, vermiculate from the same mine was imported to the UK for use as insulation in our homes prior to the 1990s, so it is possible that if your home contains very old vermiculate insulation it could too be contaminated with asbestos.

How to deal with old vermiculate insulation

Asbestos is a very dangerous substance that poses numerous health risks. It is a known carcinogen and can cause a variety of serious lung diseases and health problems.

If you suspect that your insulation could be contaminated by asbestos, then it is very important not to touch or disturb it any way as asbestos is most dangerous when it becomes airborne.

Instead, seek help from a professional who is licensed in the removal of asbestos. They can then test for the presence of asbestos and safely remove the insulation if necessary.

Spray foam insulation

If you are removing old insulation from your roof, then it will need to be replaced with a new insulation material to keep your home warm, comfortable and energy efficient.

How to handle noisy neighbours

Excessive noise pollution from neighbours is not only annoying, with time it can also begin to negatively impact your health and wellbeing.

Even your dream home can turn into a nightmare if the wrong people move in next door. Whether it’s all-night parties, arguments, barking dogs or musical instruments, here are your options for dealing with noisy neighbours.

Communicate calmly

In most cases, people don’t even realise that their actions are disturbing those around them. The very first thing to do if your neighbours’ noise is disturbing you is to pop round and have a word with them face to face.

Make sure that you’re polite, amiable and calm and provide examples of times when their noise has disturbed you and how it has affected you or your family. Try to avoid letting the conversation turn confrontational.

Report noise to the council or a private landlord

If you have tried speaking to your neighbour about their noise to no avail, you may wish to report their behaviour to their landlord or to the council.

Before doing so it can be useful to keep a noise diary of all disturbances so that you have specific examples to talk about. The council has a duty to investigate activity that can be classed as a ‘statutory nuisance’, such as excessive noise.

If the property is privately rented, then your neighbour may be breaching a clause in their tenancy agreement.

Bear in mind that reporting your neighbours can raise tensions and it’s always best to try to resolve the problem between the two of you first if possible.

Mediation

Mediation is a process where parties meet up, usually in a neutral environment, and communicate to resolve a disagreement. Mediation is controlled by a trained independent third party and you may be required to pay for the service.

Go to court

Taking your neighbour to court should only be used as a very last resort. The process can be time-consuming, costly and very messy.

Install sound insulation on your home

It may not be that your neighbours are excessively noisy, it could just be that you have paper thin walls. If you can hear every cough and sneeze from next door, then the chances are that they can hear you too. If you plan on staying in the same house for the foreseeable future then installing sound insulation in your home could be a good investment for the future.

Home improvements to help fight climate change

Fighting climate change starts at home. Make one or more of these eco-friendly home improvements to reduce your carbon footprint.

According to the Committee on Climate Change’s report ‘UK housing: Fit for the future?’ domestic energy use accounts for 14% of the UK’s total carbon emissions.

As well as helping to fight climate change, living more sustainably and reducing your energy consumption can also help you to save money.

Insulate

Over half of domestic energy is used to heat our homes so it’s very important to insulate your home to minimise heat loss. Heat escapes through your home’s walls, roof, floors, windows and doors. Insulating one or more of these areas can help to reduce the amount of energy your home uses, cutting your carbon footprint as well as your energy bills.

Here at Metropolitan Insulation ourspray foam insulationbonds to the structure of your roof, filling and sealing all gaps and cracks to get rid of all air leakages and strengthen your roof’s structure. To find out more, give our team a call on 0800 028 4042.

Low-carbon heating systems

Many homes still use very old and inefficient gas or oil boilers and heating systems. Updating your boiler to a new and efficient model or a renewable energy heating system can significantly reduce your home’s carbon emissions

Solar panels

Installing solar panels on your roof can be very expensive, but the savings you will make on your energy bills should mean that the investment pays for itself over time. The renewable energy you generate can then be used for heating, hot water and electricity in your home.

Energy efficient home appliances

If you’re renovating your kitchen or utility room always shop around for energy efficient appliances. Check the energy ratings label on an appliance before buying, those with A+ ratings are more environmentally friendly and will cost less to run.

Why and how to eliminate thermal bridges from your property

To effectively insulate a property, it’s important to eliminate thermal bridges.

Sometimes referred to as a cold bridge, a thermal bridge is a weak point in a property’s insulation.

Thermal bridges most commonly occur when there is a gap or hole in a building material where heat loss occurs. They also occur at areas near highly conductive materials like wood, metal and steel. Areas susceptible to thermal bridges include joints between the roof, walls and floor, and holes made for running cables and pipes through the building.

Why eliminate thermal bridges?

Benefits of eliminating thermal bridges from your property include:

Decreases heat loss.
Makes the property more energy efficient.
Makes the property more comfortable.
Reduces energy bills.
Reduces risk of condensation, mould and damp problems.

How to eliminate thermal bridges from your property

Design and build with thermal bridging in mind– the most effective way to eliminate thermal bridges from your property is to take care when building or decorating to consider thermal bridges in the design and plan. Of course, this doesn’t help with any existing problems.

Fill cracks and gaps– If you discover any cracks or gaps in your property’s structure, then they should be sealed immediately by fixing or filling them.

Replace old windows and doors– Draughty old windows, doors and frames should be replaced with new and energy efficient UPVC versions.

Wall insulation– In some instances, thermal bridges are caused by less obvious problems than a hole in the wall or ceiling. If elements of your building’s structure are causing repeating thermal bridges, you can rectify them by installing wall insulation. Depending on your property type, either cavity wall insulation, external wall insulation, or internal wall insulation may be suitable.

Foam spray insulation – If thermal bridging is present in your roof, spray foam insulation can effectively seal the roof, preventing air leakages and providing a vapour control layer to control condensation.

What grant schemes are available in the UK for sound insulation?

If transport noise pollution is disrupting your home life, you may be able to get help with paying for soundproofing with one of these schemes.

Constant exposure to noise pollution can have a negative effect on sleep, health, and wellbeing, it has even been linked to serious health problems like stroke and heart attack.

If you’re suffering from excessive noise pollution at home because of a nearby road or air traffic, then you may be able to receive financial help towards the cost of having sound insulation installed in your home.

Noise pollution from Highways England roads

If the rumbling sound of traffic from a Highways England road is affecting you at home, you may be eligible to apply for sound insulation.

The Highways England noise insulation schemeis available to properties that lie within a Highways England “Noise Important Area” that contains fewer than 10 properties.

“Noise Important Areas” are the areas that experiences the highest levels of noise from Highways England roads.

If you meet the scheme’s criteria then your property will be assessed and Highways England contractors will carry out the soundproofing work for you, it is not a grant scheme.

Noise pollution from airports

Most airports have noise limits and restrictions on flight paths, to minimise noise and disruption to residents living nearby. Despite these restrictions, noise from aircraft can still be very disrupting and even damaging to the health of those living nearby.

Because of this, UK airports run grant schemes to help those affected by noise pollution to soundproof their homes.

The airport in question will usually have a boundary in place that identifies the properties that are eligible.

Contact your local airport by telephone or check their website to find out details about their scheme and whether you are eligible to help with soundproofing.

For more information about the soundproofing and sound insulationproducts we provide here at Metropolitan Insulation, give our team a call on 0800 028 4042.

Difference between surface & interstitial condensation?

Condensation is an annoying and potentially damaging household problem that most homeowners will encounter at some point.

Signs of condensation include water droplets on windows and walls, damp patches, and mould. Condensation can look unsightly, cause damage to your home, and create unhealthy living conditions.

How is condensation formed?

Condensation is caused when warm water vapour in the air hits a cold surface. The cold surface cools the water vapour to a temperature that is below its condensing point, turning it from a gas back to a liquid.

Interstitial condensation versus surface condensation

There are two different types of condensation, interstitial and surface. The main difference between the two is where they occur.

Whilst surface condensation appears on the surface where it is visible, interstitial condensation occurs inside the layers of your building’s walls, roof or floor where it cannot be seen.

Of the two, interstitial condensation is usually the more damaging problem. As this type of condensation occurs within your building’s fabric, it may have caused considerable deterioration of your building’s internal elements before you notice the signs that there is a problem.

Top tips for banishing condensation

A few simple ways to reduce levels of condensation in the home include:

Open vents, windows or doors when steam from washing or cooking is present.
Keep the temperature in your home consistent.
Ensure your home has adequate ventilation.
Ensure your home has adequate insulation.
Insulate your home using a water vapour resistant material like our spray-applied polyurethane foam.

Is Your Insulation Fire Rated?

You may be starting a new insulation project or considering replacing the insulation you have as the cold winter months set in but have you thought about the fire resistance of the material you’re using? Before fitting insulation, it is important to consider how it might behave in a fire to ensure you are making the best choice and don’t end up with a material that catches fire easily or readily emits toxic smoke. With this in mind here are the most common insulation types together with information on how resistant they are to fire.

Rockwool
Mineral is regarded as one of the best materials when it comes to fire resistance. It is able to withstand heat more than 700 ºF above that of the average home fire.

Spray Foam
Many people assume spray foam to be flammable but it actually contains fire retardants. The material also fills air gaps more effectively than other insulation types cutting off the air that is a major ingredient allowing fires to spread.

Foam Board
Foam board might be cheap and readily available but it certainly isn’t a good performer when it is subjected to heat from fires. Add to this the toxic fumes you get when it burns and you may need to reconsider installing it

The Relationship Between Climate and Insulation

Most of us know that insulation is an important part of any building we occupy and increasingly so now that we are being forced to consider how much energy and consequently money we are wasting.

Money is also a factor in the type of insulation people choose for their homes. Often there are attempts to go it alone and do a DIY job to save even more. After all there are plenty of helpful videos available on Internet or advice from friends to teach you. What often cannot easily be gained from watching other people’s experiences is the insulating materials and methods you’ll need for different types of climate.

Climate is one of the key considerations when choosing insulations and depending on where you live in the UK some insulation types can be better than others. If you live in western parts of the UK the climate is often wet and windy for a large part of the year as this part of the country takes the brunt of weather coming from the stormy Atlantic. That said, temperatures don’t usually fluctuate too rapidly.

The east side of the UK can get very cold with temperatures fluctuating wildy at times as the cold North sea often exerts its influence. Weather in the east is also drier than the west.

In the South East, the weather is particularly dry through summer and also warmer with hotter summers.

So if you live in a colder climate keeping out cold will be the priority whereas in the warmer parts of the country keeping out heat while also protecting against the cold will be the priority.
