Is Spray Foam Roof Insulation a Good or Bad choice?

Spray foam insulation is frequently found at the joist or at the rafter level. During the colder months, this form of insulation aids in reducing heat loss and maintaining the warmth of the home. Additionally, it helps keep a building from being too hot throughout the summer.

Typically, this kind of insulating foam is poured into place as a liquid and is mostly composed of polyurethane. Upon contact, the foam gradually increases in size by up to 100 times to form a useful coating of hardened foam that acts as insulation. However, is spray foam roof Insulation good or bad, the right time to find?

Spray foam roof insulation: good or bad choice?

Let us begin with the bright side of spray foam roof insulation. Many spray foam insulation experts will inform you that this substance strengthens your roof as a whole by keeping slates and roof tiles in place. This improves roof insulation and guards against water tanks and pipelines freezing.

By adding spray foam roof insulation, you are giving yourself and your family access to a dry, clean, and functional attic space. The process is also very quick and simple to implement by a qualified crew of insulation experts.

Spray foam roof insulation offers other benefits, such as:

Reduces the cost of your energy bills

• Air-tight seal

• Outstanding moisture barrier

• Resistant to mould

• Long lifespan

• Ecologically sound

But how about the gloomy side of the spray foam insulation? There is frequently one major issue for many individuals who have utilised this form of insulation in the past. The material's strong moisture barrier properties and ventilation are the key problems. Your home needs ventilation to allow for the circulation of fresh air and the escape of stale air.

This ventilation gap can be closed off by spray foam put to the bottom of your slate roof. Foam completely covers your roofing slats and the base of your rafters, trapping moisture inside.

A skilled specialist should install spray foam insulation. It is crucial that a qualified individual does this task because spray foam might occasionally release dangerous chemicals.

Always leave a Ventilation Gap

It is crucial that you allow a gap that can be vented between your roof shingles and any insulation you employ. This is done to give moisture a place to exit your roof before it settles and starts to destroy the wooden roof rafters. The cost of a brand-new roof is significantly more than that of fresh insulation.

This problem is completely avoidable with the right installation methods and competent techniques. Contact our staff right away if you would like additional details on the value of airflow or how to avoid it.

How Do I Install Spray Foam myself?

Better not to give any attempt at all. A skilled specialist should install spray foam insulation all by himself. Spray foam can occasionally release harmful gases, so it is crucial that a knowledgeable and skilled individual should handle it.

What are the roof and loft insulation?

You have probably heard the term "roof and loft insulation” before, which essentially refers to any sort of insulation placed in the roof or possibly the loft of a home. Loft insulation is the process of installing a layer of material into the loft to create a barrier that stops heat from leaving during the winter and aids in keeping the house cool during the summer. The roof's joists, or the beams that run horizontally over the floor, are typically where the insulation is placed. Any area of the loft that is insulated can efficiently keep heat in by lowering heat loss.

The location of the insulation will directly affect how your loft can be utilised. If you insulate between the joists, the loft will be cold but the living area below will be kept warm. This is a "cold loft," which is appropriate for storing requirements.

It will be possible to keep the house and loft warm if you want to place insulation in the beams, which allows you to think of using the loft as an extra room or living area. Increased energy efficiency, decreased heating costs, and perhaps even a rise in home value are just a few of the major advantages of putting insulation in the loft.

Costs and Savings with Roof Insulation

Costs and Savings with Roof Insulation

Roof and loft insulation not only saves money on installation costs but also lowers annual energy costs as a result of a home that is much more energy efficient. Even for detached homes, you can generally anticipate making your installation expenditures recoup within two years.

If hiring a professional, you can think about having this job completed consecutively with other home repair projects to save on labour and opt for costs and savings. Having strong home insulation is essential whether you are considering an air-source heat pump or dual heating.

It is worthwhile to review your home's Energy Performance Certificate if you have access to one to see if any spray foam insulation cost suggestions are made that may specifically include the roof and loft.


One of the parts of the house where heat loss is the greatest is the loft. In reality, 25% of all heat is lost through a home's roof. Therefore, adding insulation here is an effective approach to prevent the loss of heat and to maintain your space comfortable in the winter as well.

The long lifespan of loft insulation allows you to reduce your energy costs. It can last for years, letting you recover your initial costs just to save money each year through decreased annual energy bills.

It is also important to emphasise the environmental advantages as good loft insulation helps a home fight climate change and lower its carbon impact. Because there will be less heat loss, the heating system won't need to run as long and the house will store heat for longer, requiring less fossil fuel to keep your home warm.
