Sun and temperature swings evaporate the natural oils in bitumen, and the roofing hardens. Enkonol treatment soaks into the membrane and restores its flexibility.
Enke Werk products may only be installed by authorised, certified installation teams. KattoFIXer is one of them.
The roofer next door says nothing can be done for a bitumen roof and it has to be replaced now. We maintain bitumen roofs dating from 1992.
Enkonol penetrates deep into the membrane and restores the bitumen's elasticity. The roofing stops cracking, and on granule-surfaced bitumen the treatment also binds loose granules.
Combined with Enkopur® sealing of critical seams, it is a safe, cost-effective way to extend the life of a bitumen roof without premature replacement.
Granule-surfaced roofing collects moisture, moss and dirt that slow down drying. Smooth roofing such as Derbigum dries faster. Either way, regular maintenance matters more to the roof's condition than the roof type.
Inspections and maintenanceEnkonol is made by Germany's Enke-Werk (Joh. Enke GmbH & Co. KG). Quality since 1924.
RoofTech Oy is the official importer of Enke Werk products in Finland.

Privacy policyIn many cases, yes. Targeted repairs, sealing of risk points, protective treatments and regular monitoring keep a roof working for longer. The key is to identify what needs action now and what can wait.
Yes. Winter sealing can be applied to wet surfaces and in temperatures as low as −25 °C. The leak is stopped straight away, and the permanent repair is done when the weather allows.
Spring and autumn are the key times. In spring you can see any damage from winter and snow clearing; in autumn you make sure the roof and drainage work before winter.
When nobody keeps an eye on the roof, drying out and cracking of the roofing with age go unnoticed, as do dirt, moss, standing water, splitting seams and minor damage. Systematic maintenance and checking that the roof stays watertight and elastic are the most important ways to extend the life of a flat bitumen roof.

KattoFIXer.fi is the marketing name of Gewerk Finland Oy's (Business ID 3631966-2) services for housing companies. We are an authorised Enke Werk installation team and have been looking after roofs since 2013.
We don't sell complete roof replacements. We only recommend replacement when repairs and maintenance alone are no longer worthwhile.
The product is for professional use only and may be installed only by a trained and certified installation team. KattoFIXer is an authorised Enke Werk installation team.
The sealing is used on metal, standing-seam and bitumen roofs, for example, as well as in gutters and roof windows. We always assess suitability on site.
Yes. The sealing can be painted over. On metal roofs we recommend EMP anti-corrosion paint.
Enkopur® sealing has a technical service life of 25 years.
One high-build coat is enough. EMP (Enke Multi Protect) bonds chemically to the metal and stops corrosion.
EMP is solvent-based, so it dries quickly. The surface is rainproof after about 30 minutes.
The standard colours are anthracite, red-brown, grey, patina, black and white-grey. Custom tinting is also available to order.
Not necessarily. Enkonol treatment soaks into the membrane and restores the bitumen's flexibility. We maintain bitumen roofs dating from 1992 that have still not been replaced.
No. Enkonol does not seal on its own. Sealing is done with Enkopur® before the bitumen treatment.
All bitumen roofing: flat and pitched roofs, plus granule-surfaced and smooth Derbigum bitumen roofing.
Arctic Seal is suitable for metal, bitumen, tile and other roofing materials.
Arctic Seal stops the leak immediately, whatever the weather. When conditions allow, the leak point is sealed with long-life sealing.
Detached houses, terraced houses and small blocks of flats are cleared safely from the ground with high-pressure vacuum equipment up to a height of 12 metres. Larger buildings are cleared from the roof using a vacuum truck.
Autumn offer from 99 € (incl. VAT 25.5%) in Tampere and the surrounding area. The final price depends on the size and complexity of the property. Order together with your neighbours and we'll take it into account in the price.
The labour cost is eligible for the household tax credit for private customers.
When water can't reach the downpipe, it overflows and can get into the structures. Decaying debris corrodes the gutters and adds weight, and in winter the blockage freezes.
For most roofs we recommend an inspection in spring and autumn. The interval can be adjusted if needed, based on the report.
Leaking water soaks insulation and structures long before it shows indoors. An inspection finds the risk points before they become leaks, and regular maintenance keeps the roofing's service life where the manufacturer promised.
Photos and findings, recommended actions in order of urgency, cost estimates and maintenance instructions. Every visit is archived as a roof history that stays with the property.
Yes. Urgent repairs are carried out during the same visit, so the property manager doesn't need to order them separately. The scope of repairs is agreed when the lifecycle contract is signed.
Yes. The report is designed so that the actions and their urgency can be transferred directly into the maintenance needs assessment.
Yes, when needed. We are a drone operator registered and approved by Traficom.
You choose the recipients yourselves – for example the property manager, the maintenance company and the chair of the board. Alerts arrive by text message and/or e-mail.
In existing buildings, structures do need to be opened up. The sensors are wireless, however, and can easily be installed in new builds during construction.
The sensors' built-in battery lasts more than 20 years.
Yes. System installation and equipment are charged separately. Monitoring complements the spring and autumn inspections, and alerts are logged in the same maintenance history. Monitoring is also charged at a monthly fee based on the number of sensors.
An initial inspection goes over the roof and photographs it. A lifecycle plan is then drawn up, scheduling and pricing the actions for the budget. Spring and autumn visits cover inspections, minor repairs and the gutters, and the board receives a report after every visit.
Yes. The actions are scheduled, so they can be transferred directly to the PTS and the budget.
No results. Give us a call – we're happy to help.
