Water ingress from a leaking roofvent is a common problem on panel van conversions. This was a problem for a recent customer who spotted water damage on the underside of his roof. The only way to sort this out is to remove the roofvent,clean all the old silicone off and prepare the surface. Repair any damage around the rooflight,reseal with a non-drying bedding sealant and refit the roofvent. This can be a challenging job as all the old sealant needs to be removed fully to ensure a good joint is maintained when fresh sealant is applied. The customer will now be able to sleep soundly in his bed next time it rains!
