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

If you're looking to buy a house in Fairwater, Cardiff, you may come across properties with flat roofs, particularly extensions, garages, porches and some more modern homes.

But should a flat roof put you off buying a property?

Not necessarily. While flat roofs can require more regular inspection and maintenance than traditional pitched roofs, a well-installed and properly maintained flat roof can be perfectly suitable for a home.

At Fortis Estate Agents, we know the Fairwater property market and understand that buying a home is about looking beyond the first impression. When viewing a property with a flat roof, there are a few practical things worth considering before making an offer.

Here are five things to look out for when buying a house with a flat roof in Fairwater, Cardiff.

What Is a Flat Roof?

Put simply, a flat roof is a roof with a very low pitch rather than the more obvious slope of a traditional pitched roof.

A property may have a completely flat roof, but it's more common for a house to have a combination of pitched and flat roofing. For example, flat roofs are often found on:

• Extensions
• Garages
• Porches
• Rear additions
• Dormer extensions
• Modern architectural features

Flat roofs can be constructed using a range of materials, including fibreglass (GRP), felt or modified bitumen, EPDM rubber membranes, PVC and built-up roofing systems.

The material, age and condition of the roof are all worth considering when viewing a property.

What Should You Know When Buying a House With a Flat Roof?

If you're searching for property for sale in Fairwater, Cardiff, don't automatically rule out a house simply because it has a flat roof.

Instead, consider the condition of the roof, how old it is, how it has been maintained and whether a professional inspection is recommended.

Here are five key things to consider.

1. Flat Roofs Can Be More Prone to Leaks

One of the main concerns buyers have about flat roofs is water.

Unlike pitched roofs, where rainwater naturally runs down the slope, flat roofs rely on their drainage system and slight falls in the roof design to move water away.

If drainage becomes blocked or the roofing system deteriorates, water can potentially collect on the surface and eventually find its way into the property.

When viewing a property, look out for signs such as:

• Water staining on ceilings
• Damp patches
• Bubbling or damaged roofing materials
• Mould or musty smells
• Signs of previous repairs
• Blocked or damaged gutters and outlets

A surveyor can also assess the condition of the roof as part of the home-buying process.

2. Your Buildings Insurance Could Be Affected

The type and extent of flat roofing can affect buildings insurance.

Some insurers may consider properties with a significant amount of flat roofing differently from properties with conventional pitched roofs. Premiums and terms can vary depending on factors such as the proportion of the property covered by flat roofing, its construction and its age.

If you're considering buying a property with a flat roof in Cardiff, it's worth obtaining an insurance quote before committing to the purchase.

That way, you'll have a better understanding of the ongoing costs of owning the property.

3. Mortgage Requirements Can Vary

Another consideration when buying a house with a flat roof is your mortgage.

Some lenders may have specific criteria relating to properties with flat roofs, particularly where a large proportion of the property is covered by flat roofing.

The requirements can vary between lenders and depending on the construction and condition of the roof.

If you're buying a property in Fairwater, it's therefore worth discussing the property with your mortgage adviser or lender early in the process.

A mortgage restriction isn't necessarily a reason not to buy a property, but it's something you'll want to understand before progressing.

4. Consider Future Resale

When you're buying a house, it's worth thinking beyond your own time living there.

Some buyers may be perfectly happy with a flat roof, while others may prefer a traditional pitched roof. This could potentially affect the pool of buyers interested in the property when you eventually come to sell.

However, location, condition, price and the overall appeal of the property will also play an important role.

This is particularly relevant when considering property in popular parts of Cardiff such as Fairwater, where buyers may be comparing several homes at different price points.

A flat roof shouldn't automatically make a property difficult to sell, but it is one factor worth keeping in mind.

5. Maintenance Can Be Important

Flat roofs need appropriate maintenance to remain in good condition.

Depending on the roofing material and age of the roof, this could include checking drainage, removing debris and addressing minor problems before they develop into larger repairs.

When viewing a property, ask:

• How old is the flat roof?
• What material was used?
• When was it last repaired or replaced?
• Are there guarantees or paperwork for previous work?
• Has the roof ever leaked?
• Are there any known maintenance issues?

If you're seriously considering making an offer, your surveyor can provide further advice on the condition of the roof.

Should You Buy a House With a Flat Roof?

A flat roof doesn't necessarily mean you should rule out a property.

Modern flat roofing systems can be durable when properly installed and maintained, while flat roofs can also form an attractive part of a home's design.

There can be several advantages, too.

Potential benefits of a flat roof include:

• Modern appearance: Flat roofing can create a clean, contemporary look.
• Roof lanterns: Extensions with flat roofs can provide an opportunity to install roof lanterns or rooflights, bringing more natural light into the home.
• Outdoor space: Depending on the design and construction, some flat roofs may be suitable for balconies or roof terraces, subject to the appropriate permissions and structural requirements.
• Green roofs: Certain flat roof systems can be adapted to support green roof installations, potentially providing environmental and insulation benefits.
• Potentially simpler repairs: Access to some flat roofs can make certain maintenance and repair work more straightforward, although costs will depend on the problem and roofing system.

Ultimately, the important thing isn't simply whether a property has a flat roof. It's the condition, construction, age and maintenance history of that roof.
