Roof renovation

Extra insulation and a new finish for your roof
At ease again with a renewed roof

Thanks to Cleys.

Heat. In winter you have too little of it, in summer far too much. Insulation helps to counter these large temperature differences. Did you know that on average 30% of your heat escapes through the roof? Time to change that.

A roof renovation by Cleys makes your home more resistant to heat and cold. We remove the existing finish, install an efficient insulation layer and complete it with under-roofing and sealing. Ready to lower your energy bill?

How we approach your roof renovation

Cleys specializes in insulating and waterproofing existing roofs. Most customers choose to combine both. This way, you benefit from attractive government grants. Read on to learn more about the “Mijn VerbouwPremie” for roofs.

On a flat roof, we install the insulation and the new roofing on top of the existing roof. On pitched roofs, we remove the tiles or slates and the battens. Then we insulate your roof and finish it with the covering of your choice. Depending on the type of roof and the weather conditions, insulating and replacing your roof takes from a few days up to a week.

Having your roof renovated: here’s what you should keep in mind
Conditions and permits

We only renovate roofs whose structure is in good condition. In advance, we check whether there are any leaks or sagging in your roof, whether your roof is damaged, and whether the structure provides sufficient load-bearing capacity and support for the new insulation and roofing.

A permit for a roof renovation is usually only required when you opt for a major aesthetic change. To be sure, check with your city or municipal services whether you need to apply for a permit to renew your roof.

Grant for roof renovation
A boost to renew your roof

A roof renovation with a focus on improving your roof insulation is not only good for your energy bill. You also help achieve climate targets. That’s why the Flemish government gladly provides financial support in the form of the “Mijn VerbouwPremie” for roofs.

Grants for a roof renovation start at 8 euros per square meter. The total compensation depends on, among other things, the purpose of the building, your income category and the total invoice amount. Discover all the details about possible grants and loans for renewing your roof.

How much does a roof renovation cost?
The price of renewing your roof

The price of a roof renovation is custom work. Costs depend on many factors. Consider for example the following:

  • Surface area: the larger your roof, the higher the total costs, but the lower the unit price.
  • Appearance of the roof: renovating a flat roof is cheaper than a pitched roof with roof windows.
  • Level of difficulty: edge finishing is expensive, so renovating a roof with many corners and details costs more.

Cleys specializes in renewing the entire exterior shell of your home. Curious how much insulating and finishing your facades would cost? Make an initial calculation with our facade calculator.
