Water damage to metal roofs
Double standing seam roofs, especially metal roofs with a slight incline, draw in water through the capillary effect (known as the suction effect) through the gutter and collar area between the metal roof and the roof structure. This is a common problem, even though the gutters are based on the guidelines and the current industry standards.
In my many years working with tin and on roofs, I have been regularly confronted with this problem, which can cause substantial damage for my customers, often after just a short time. There is now a solution to prevent these problems for the whole tin works, plumbing and roofing industry.
Avoid water damage to metal roofs
KAPIpro® capillary profile
Our solution is simple, cost-effective and ultra-efficient!
It interrupts the capillary effect of the water and prevents it penetrating through the gutter area between the metal roof and the roof structure. This means it provides damp protection for the metal roof. The innovative folding and perforation of the stainless steel profile guides the water into the gully. It stops the capillary effect and protects the metal roof from water ingress!
The capillary profile is made from stainless steel and can therefore be combined with all types of metal. It is available in L x W 100 x 24 cm and in metal thicknesses of 0.6 mm and 0.8 mm.
In order to achieve the highest possible level of dryness in the gutter area of the metal roof, fitting the KAPIpro® standing seam compression tape is a must.
• Sustainable and gentle on resources! ☘
Our capillary profile and compression tape help save and protect resources. Save valuable metals and construction materials. After all, a dry metal roof lasts longer.
• Saves time!
Fitting the KAPIpro ® capillary profile means there is no need for the complex process of folding the inlet plate with engaged suspension lug, also known as a Swedish brake. The profile makes a quick, clean formation of the gutter possible. This means easy, low-cost installation with a real impact. So there is nothing standing in the way of long-term customer satisfaction.
• Suitable for listed buildings ⚒
Our capillary profile is virtually invisible when fitted. All you can see is the drip gulley which is covered by the guttering. The view of the listed building is not impaired.

KAPIpro ® compression tape
It is fitted to the double standing seam of the metal roof and prevents water ingress into the gutter and collar area, e.g. following a build-up of ice. The compression tape, which is made especially for the standing seam roof, is 35 mm in width.
In order to achieve the highest possible level of dryness in the gutter area, fitting the KAPIpro® compression tape is a must. Avoid water damage to metal roofs and use the KAPIpro® compression tape.
