Financing a roof renovation: which loan fits roof and insulation?

A roof renovation is one of the bigger single measures on a house. Work out the rate and check whether an instalment loan is enough or a mortgage-backed loan is better.

How do I finance a roof renovation?

A roof renovation can be financed by an instalment loan without a land registry entry, a top-up of an existing mortgage or a mortgage-backed loan. With insulation, funding may apply. Above about €50,000 the mortgage-backed route is usually cheaper.
