Properties with a flat roof are often classified as ‘non-standard’ types, meaning they are regarded as higher risk by lenders. Flat roofs can be more prone to leaks and require higher maintenance.
However, it is still possible to get a mortgage on a property with a flat roof, particularly with the support and guidance of expert mortgage advisors such as Barlow Irvin.
Can you get a mortgage for a flat roof property?
You can definitely get a mortgage on a flat roof property, though it can be slightly more complex than getting a standard mortgage on a pitched roof.
The potential for leaks combined with higher upkeep and maintenance costs means that your mortgage application is likely to undergo a lot more scrutiny from lenders before it is accepted. As a result, it’s a good idea to discuss your options with an experienced local broker upfront.
Flat Roof Mortgage Advice
What are flat roof mortgages?
Put simply, ‘flat roof mortgages’ are mortgages on properties/houses where a significant portion of the roof is flat as opposed to being slanted or pitched.
Many lenders have certain policies in regard to the proportion of a roof which is flat when considering applications and their risk, whilst others do offer specialised 100% flat roof mortgages too.
A recent inspection, a valid warranty or evidence of a recent roof replacement typically increase your chances of getting an approved application.
What to consider about mortgaging a home with a flat roof
When getting a mortgage on a home with a flat roof, there are a couple of factors that you need to consider:
Lender classification - Understanding what each lender regards as a ‘flat roof’ property is vital. Typically, roofs with over 20-30% flat space fall into this category. Many lenders offer mortgages with larger deposits or higher interest rates.
Insurance costs - The higher risk associated with flat roofs means that insurers will assess materials used and build quality, potentially leading to higher premiums.
Structural requirements - A variety of issues such as blocked drains, pooling water, degradation, damp and rot are all more common with flat roofs. As a result, you may need to locate valid warranties and building regulation certificates before securing a loan.
Future resale value - It’s important to consider the long term. Many buyers aren’t interested in flat roofs, so if you ever come to sell the property, you may find it more difficult.
