KrolockWe had an old house fitted with a new roof according to WK guidelines. The exterior insulation consists of PUR/PIR rigid foam with an upper layer of a 3-ply underlay membrane, class UDB-A, made of polypropylene. On the underside, it is combined with a 3 cm (1.2 inches) wood fiberboard and a membrane foil. A vapor retarder was properly installed.
After the roof was closed, a smell resembling cat urine started, and this condition has persisted for 5 months now. The insulation manufacturer verbally advised against removing the attic insulation because the odor even penetrates the membrane foil. According to the specialist dealer, the smell originates from cutting the wood fiberboard, and indeed, the odor at the cut edges closely resembles cat urine. However, it was expected to stop after 2-6 weeks, but the smell remains omnipresent.
We therefore gave the roofer a one-month deadline. We only received an email stating that he would take care of it. Then the insulation supplier came once, smelled the area, and confirmed that removal is not an option. Now the deadline has passed, and the tenant of the house is asking how the renovation of the rented attic space will proceed.
Are there any suggestions for defect remediation (ventilation, odor absorbers, etc. – forget about those!) if not for evidence preservation – how should one proceed in this situation?
The roof cost was 30,000 euros. Now it will certainly not get cheaper, considering expert assessments, rent reduction, disposal, another six months of work, and all the related hassle.
