Polycarbonate Roofing Repair
Yellowing, rattling sheets or leaking joints, polycarbonate roof repairs across Plymouth and Devon, fixed at the actual cause.
Polycarbonate roofing problems tend to fall into a few clear categories: UV degradation causing yellowing and brittleness (usually a failed protective coating or a non-UV-stabilised sheet), sheet movement and rattling from incorrectly spaced fixings, glazing bar seal failure letting water track in at the joints, and algae growth within the wall cavities of the sheet.
Sherford Roofing repairs polycarbonate roofing across Plymouth and Devon, replacing degraded sheets and correcting fixing faults so the repair doesn't recreate the same movement or leak problem.
Our Process
Assess the Sheets
We check for UV degradation, cracking and fixing faults across the roof.
Diagnose Leaks
Joint seals, end closures and glazing bars are checked to find the actual source of any water ingress.
Replace or Refit
Degraded sheets are replaced; incorrectly fixed sheets are refitted with correct spacing to allow for thermal movement.
Reseal Joints
Glazing bar caps and seals are refitted to complete a weathertight repair.
