Replacing roofing felt from inside a building presents several significant challenges and limitations that must be carefully considered. One of the primary concerns is related to structural integrity. Roofing felt is typically installed as a protective layer between the roofing material and the underlying structure, which means that disrupting this layer from the interior could compromise the roof’s overall stability. Attempting to remove or replace roofing felt from inside the house may inadvertently cause more damage than intended, potentially leading to leaks and structural failures.
Accessibility is another key factor that complicates this process. The nature of roofing felt installation requires that the material be fitted into a tight space and anchored securely to the roof deck. This positioning can make accessing the felt from the interior particularly difficult, often necessitating the removal of ceiling panels and insulation. Furthermore, these actions can create additional work and potential damage, leading to increased repair costs. Entering the roof structure from the inside often doesn’t provide the necessary access to evaluate and replace the felt efficiently.
Moreover, adequate ventilation is crucial when dealing with roofing materials. Insufficient ventilation can lead to moisture build-up, which can further exacerbate roofing issues. If roofing felt is replaced from the interior without ensuring proper air flow, it may result in an inadequately ventilated space, heightening risks of mould growth and additional moisture damage. Generally, roof replacement, including the installation of roofing felt, is performed from the exterior as this method offers the best access to inspect and address any underlying issues thoroughly.
In light of these complexities, it is essential to recognise that while replacing roofing felt from the inside may seem feasible, it often leads to complications that necessitate a more comprehensive approach. Understanding these challenges highlights the importance of professional intervention when addressing roofing issues.
