How Do I Know If My Bay Window Roof Needs To Be Replaced?

If you have noticed any leaks or damp patches or can see the roof beginning to bow or shed then, it may be time to arrange your bay window roof replacement. When it comes to choosing the best replacement materials, there is a wide range of options to choose from. Don’t worry about choosing as we are here to help and we would be happy to advise you on the options available so that you can enjoy a home that is warm, secure and looks fabulous.

Which Materials Are Available For Bay Window Roof Replacement?

Picking out a specific material depends on your location, the style of your home and your overall budget for the project. The most commonly used materials for replacement bay window roof work includes:

  • EPDM – which a durable and practical material that doesn’t look as great as the rest but offers the robust support you need.
  • Felt – a commonly used material that looks good on the roof but is not decorative like other options. Felt roofs are installed by using a flame to adhere the material to the area.
  • Lead – a very popular option, especially if you are keen to maintain a timeless look. However, the lead flashing can sometimes attract thieves so you will need to be prepared to replace it if it is stolen.
  • Fibreglass – this is a cheaper option than lead but looks great once it has had time to settle and age.

What Covering Should I Choose For My Replacement Bay Window Roof?

Now you know the types of material available to you, we have taken the time to share more information on each choice so that you end up with the right materials for you home and your bank balance. When you decide on the type that you like the best, get in touch and let us discuss the work that needs to be done. We are always happy to advise and will provide you with quotes for more than one type of roof if you are not sure which one to choose.


If you have ever seen a flat roof, then the chances are that you will have seen EPDM in action and while it is not commonly used for a bay window roof, it is a hard-wearing, strong and long life option. It is generally best used on larger projects that require the strength it offers and where it is not a focal point for the aesthetics of the house.

EPDM is easy to install and can be done quickly and efficiently as long as you appoint a contractor that has worked with it before. While EPDM may not be the prettiest choice, it may be the most practical if you want hard-wearing results and don’t care about the overall look of your property when it is complete.


Felt roofing went through a period of real popularity some years ago, but this dwindled when new materials came to the market that offered easier installation and less ongoing maintenance needs. This does not mean that felt should be discounted out of hand!

To successfully enjoy a felt roof, you need to have it installed properly with hard-wearing aluminium edging to secure it. Many people have had trouble when it comes to this roofing because they have not employed an expert to fit it. With proper research, you should be able to enjoy a felt roof without too much hassle. Don’t forget that a naked flame is required to install this option; not a great plan if you have little ones running all over the place!


Lead roof options can be simple or decorative depending on the style of your home and should always be installed by an expert. Lead is an excellent choice if you have a sloping roof that will be in plain sight when you look at the frontage of your home. It is seen as a more upmarket choice and is very popular in older houses.

Because lead roofing is attractive to thieves, it is essential to consider any suitable safety measures that you need to install before you can have the roof fitted. Lead windows will last for many years, especially if they undergo yearly checks and maintenance.


Probably the most common type of roofing today is a fibreglass roof. The reason for this is that it has an exceptionally long lifespan and offers no value to anyone that may benefit from stripping it down and stealing it.

Fibreglass is also the most diverse as you can have it made in a wide range of colour choices to enable you to personalise your home. If you like the idea of a lead roof but want to save money and prolong the life of the roof then why not consider a fibreglass roof with lead flashing, giving you the best of both worlds!
