Green roof and sedum roof in Alkmaar
A sedum roof retains rainwater, cools in the summer, and lasts longer than a bare bitumen roof because the vegetation protects the covering against UV rays and temperature fluctuations. We install green roofs on flat roofs and extensions, but always only after checking whether the structure can support the weight.

Why a green roof belongs to a roofer
A sedum roof looks like a garden job, but it is primarily a roof job. Saturated with water, an extensive green roof easily weighs fifty to one hundred kilograms per square meter, and the structure must be able to support that. With an extension from the seventies, that is not a given. We check this first, because a sagging roof costs more than the greenery will ever yield.
In addition, there is still a roof covering underneath the greenery, and that must be in good condition. Installing a green roof over a covering that has reached the end of its lifespan means that you will have to remove it all again in five years. We assess the covering first and replace it if necessary, adding a root-resistant layer.

What are the benefits of a green roof
Choose quality
A sedum roof does more than just look good. These are the five most important benefits.
Your roofing lasts longer
The vegetation protects against UV and temperature fluctuations, and that makes a difference of years.
Cooler in the summer
The difference is particularly noticeable with an extension or addition with a room underneath.
Rainwater is retained
The sewer system has less to process at once during a cloudburst.
Noise from outside is dampened
The structure acts as damping, which is pleasant under an approach or traffic route.
Better for the environment
Insects and birds find something there, and that counts in a concrete neighborhood.

How much does a cost sedum roof in Alkmaar?
Clear pricing
The price depends on the surface area, the type of vegetation, and whether the underlying roofing needs to be replaced. The latter often accounts for the largest part. If structural work is also required, we will map this out separately so you can see what each item covers. You will receive a fixed price after the free inspection.
When is a roof suitable for sedum?
Good to know
The roof must bear the weight, have a slight slope of at most fifteen degrees and a roofing that will last for years to come. Flat roofs of extensions, garages, and sheds are the most suitable candidates. For a roof that is already sagging or where water collects, we will not start work until that is resolved.

Are you interested in a green roof and do you want to know what to expect? Below you will find answers to the questions we receive most frequently.
No, and that is the first question we answer. When saturated, an extensive sedum roof weighs fifty to one hundred kilograms per square meter. We assess the structure before making any proposals.
Less than people think, but not nothing. Remove weeds one to two times a year, check the drainage, and water occasionally during a dry summer in the first year. After that, sedum largely takes care of itself.
Not the greenery itself, but the covering underneath. That is why we install a root-resistant layer and assess the existing covering first. Detecting a leak under a green roof is considerably more difficult, so we want to be certain of that beforehand.
Yes, and that combination actually works well. Panels perform better on a cooler roof surface. However, the fixings must rest on ballast rather than go through the roofing, and we discuss that in advance.
Some municipalities have a scheme for this, but the conditions change regularly. We check what applies at that time when reviewing the quotation.

What comes up most often: that the cause is thoroughly investigated, that everything is explained calmly, and that the roof is left clean and tidy.
RatingPleasant and efficient roofer who immediately replaced the worn-out lead flashing at the chimney.
We had two skylights replaced with larger ones and renewed the gutters on that side at the same time. The team worked for three days, and the result is exactly what we had in mind. We already notice a difference in the amount of natural light, and the gutters slope perfectly.
Our skylight no longer closed properly and moisture was coming in when it rained. They repaired it expertly and immediately replaced the seal all around.
