Should I Buy a House With a Flat Roof? 5 Things to Consider

Many homebuyers debate whether they should buy a house with a flat roof. While flat roofs can require extra maintenance compared with a traditional pitched roof, there are upsides, too. Modern architecture and design often incorporates flat roofs, and done well, they can look stunning. Older properties though are where you may run into problems!

In this article, I’ll explain some of the main things to consider when viewing an older property with a flat roof, to help you decide if it’s the right purchase for you.

What is a Flat Roof House?

Put simply, a house with a flat roof is a house that has - you guessed it - a flat roof. Homes with flat roofs either have part of the property using a flat roof, like an extension or porch, or the whole building.

Usually, flat roofs are made from materials like fibreglass, known as GRP, felt - known as Modified Bitumen, a rubber membrane - known as EPDM, tar and gravel - known as a Built-Up Flat Roof or BUR, or PVC.

What Do I Need to Know About Buying a House With a Flat Roof?

There are definitely things you should know about buying a house with a flat roof! It’s always good to do your own research and ask your local estate agent for the full details before making a decision. But, we've put together a list of the five main things you need to know about flat roof houses.

1. Leaking is Possible

As water can pool on the surface of flat roofs during rainfall, this can weaken structures and cause leaks. However, this can be avoided if the flat roof is made from one of the more durable materials such as GRP, BUR, EPDM or PVC, or if you have your roof regularly maintained.

2. Insurance Premiums May Be Higher

Because of the added risks, some insurance premiums may be higher for a home with a flat roof compared to a property with a pitched roof. However, prices can vary depending on how much of the property has a flat roof, and what material it’s made from.

3. You May Have Mortgage Restrictions

Some mortgage lenders have restrictions about how much of the house can have a flat roof before accepting you, so you’ll need to check with your lender before making an offer.

4. Your Buying Market May Be Limited

While there’s a market for everything, some potential buyers may not want to purchase a house with a flat roof. So, you may have a slightly smaller buying market when it comes to selling in the future.

5. Maintenance Can Be Expensive

Depending on the material of your flat roof, maintenance can be frequently required and can become expensive over time.
