Buying a porch roof is one thing – getting it safely fixed to the facade is another. This is exactly where it is decided whether the canopy lasts 20 years or whether cracks appear in the render after the first wet winter. This guide describes what a specialist company actually takes care of during installation, which points are checked during on-site measuring, when self-installation makes sense – and what you have to budget for.
Why the Wall Decides the Installation
A porch roof is a cantilever: its entire dead weight plus snow and wind loads hangs from a few fixing points and acts there as a lever on the wall. That is why the critical factor is not the porch roof but the substrate.
- Solid masonry or concrete: the straightforward case. Approved anchors transfer the loads directly into the load-bearing component.
- Vertically perforated brick and aerated concrete: the loads have to be distributed via injection anchors with a sleeve, because the cavities in the block cannot take a point load.
- Facades with thermal insulation (WDVS): the most common stumbling block. Since the insulation cannot take any loads, special anchors are required. Spacer mounting systems (thermal stops) create a positive connection into the masonry behind without thermally breaching the insulation layer.
Anyone who simply drills through the insulation on an insulated facade creates two problems at once: a thermal bridge where moisture condenses on the inside, and a fixing that slowly settles under load.
What Is Checked During On-Site Measuring
On-site measuring is not a matter of re-checking the door width, but a technical survey. Consultation, planning and measuring are handled here exclusively by qualified metalwork specialists. Among the things checked are:
- Wall construction and load-bearing capacity – often only reliably established by a test drilling.
- The position of cables and pipes behind the render, particularly above the door.
- Roller shutter boxes, lintels and window reveals, which limit the mounting height.
- Water drainage: where does the water run off without icing up the footpath? This determines the drainage direction of the gutter.
- Dimensioning: so that the front door stays dry in driving rain, the porch roof should project at least 20 to 30 cm beyond the door width on both sides and be around 100 cm deep.
- Mounting height: ideally the lower edge sits 20 to 30 cm above the upper door frame – enough headroom without rain being drawn in under the roof from the side.
These points cannot be settled over the phone. That is precisely why an on-site measuring appointment is a prerequisite for a reliable commitment on larger or cantilevered systems.
What Does a Made-to-Measure Porch Roof Cost?
Custom manufacture is closer in price to DIY-store products than many people expect. Some guide values from our shop (as of 08/2026):
- Porch Roof Model Freising, glass or aluminum: from 603,69 €
- Porch Roof Model Erlangen, glass or aluminum: from 688,47 €
- Porch Roof Model Würzburg, aluminum roof: from 839,00 €
- Porch Roof Model Fürth, glass roof: from 863,55 €
- Porch Roof Calypso, VSG glass on aluminum: from 1.167,39 €
- Porch Roof Vesta, VSG glass on stainless steel: from 1.695,75 €
- Aluminum Porch Roof Platin Portal 125: from 2.243,90 €
The online configurator shows the exact price for your desired dimensions immediately – with no enquiry and no waiting. Shipping is free of charge.
And the installation? There is deliberately no flat rate for that. The effort involved depends on the wall construction, the working height, the accessibility and on whether scaffolding or a lifting platform is needed. A cantilevered glass porch roof over an insulated facade on the first floor is a different job from an aluminum mono-pitch porch roof over a ground-level front door in solid masonry. You therefore receive the installation price after the on-site measuring – as a firm commitment, not an estimate.
Install It Yourself or Have It Installed?
Both are possible, and both have their place.
In favor of self-installation: all systems are prefabricated to the millimeter and delivered ready to install – including instructions and suitable fixing material for the most common substrates. Anyone with practical DIY skills, a solid wall and a second pair of hands will manage well.
In favor of professional installation: insulated or unclear facades, large spans, glass weights above roughly 40 kg, overhead working heights – and the fact that an incorrectly placed fixing only becomes apparent after years, but is then expensive. In the Schwandorf, Cham and Regensburg region we carry out measuring and installation on site on request.
Honestly, there is one simple test: if you cannot say for certain what the wall above your front door is made of, have it installed for you.
Process and Delivery Time
- Configure: set the dimensions, material, glass type and drainage direction in the online configurator. The price appears immediately.
- On-site measuring (optional): for professional installation or an unclear substrate, an appointment on site is added.
- Manufacture: every porch roof is produced as a one-off to your dimensions – special widths are possible.
- Delivery: 14 to 35 days depending on the model and version; the binding figure is stated on every product page. Delivery is by freight forwarder or parcel service with prior notice of the appointment.
- Installation: self-installation following the instructions, or an appointment with our installation team.
Do not schedule the installation appointment for the delivery day. It makes sense to allow a buffer of a few days so that you can check the delivery beforehand for completeness and transport damage.
Does a Porch Roof Need Building Permission?
Under building law a small porch roof covering the front door is usually exempt from approval as a subordinate structure. There are two exceptions: if the building is a listed monument, or if the porch roof projects into public road space, the building authority has to be involved. Since state building codes differ, a quick call to the local council is worthwhile if in doubt – it is dealt with faster than a subsequent removal.
Conclusion
The question “porch roof with installation – what does it cost?” can only be answered properly after a look at the wall. The porch roof itself is the predictable part: choose a model, configure it, see the price, from around 600 €. The variable part is the fixing – and that is exactly where durability is decided. Anyone with a solid wall and some practical skill can install it themselves. In all other cases the specialist company is the cheaper option, even if the invoice looks higher at first.
