Sealing

Roof sealing encompasses a range of techniques and products used to close potential water entry points across the roof surface. This includes applying sealant around screw heads on metal roofs, sealing the edges of flashings, filling gaps at pipe penetrations and vent bases, and sealing the overlaps between polycarbonate or fibreglass light panels. The sealant products used in roofing must be specifically formulated for exterior use and capable of withstanding UV exposure, thermal movement, and constant moisture contact. Common roofing sealants include neutral-cure silicone (used on metal and glass surfaces), polyurethane sealant (offering superior adhesion and paintability), and butyl rubber tape or compound (used under flashings and at lap joints). The choice of sealant depends on the materials being sealed, the expected movement at the joint, and whether the sealant will be exposed or concealed. Using the wrong sealant type can lead to adhesion failure, staining, or accelerated corrosion of the surrounding materials. In Gippsland, sealing is an important part of both roof repairs and preventative maintenance. During a roof inspection, a roofing professional will check all sealant joints for signs of cracking, separation, or deterioration, and re-seal any compromised areas. Town & Country Roofing carries a range of professional-grade sealants suited to all common roofing materials and applications encountered across the region.
