Roofers in Modbury, Adelaide
Modbury is the commercial heart of the City of Tea Tree Gully, with Westfield Tea Tree Plaza, the hospital and the O-Bahn interchange surrounded by 1960s and 70s family streets on the lower foothills. Its roofs are mostly the same age and are reaching the end of their first life together.
What usually goes wrong on Modbury roofs
- Porous concrete tiles and crumbled ridge mortar after fifty summers of foothills heat
- Brittle foil sarking that tears at a touch, letting wind-driven rain into the ceiling
- Rusted valley irons under leaf litter from street trees and gums on the hipped roofs
- Cracked pointing and gutters out of fall from reactive clay movement
- Hail-dented gutters and cracked tiles after spring storm cells crossing the north-east
Local notes from the roofers
Modbury climbed out of market gardens in the 1960s and 70s, and most of its roofs are concrete tiles on brick veneer homes with the timber battens and foil sarking of that era. After fifty summers of foothills heat the tiles are porous, the ridge mortar has crumbled, and the sarking is often brittle enough to tear at a touch, so wind-driven rain from the south-west gets past the tiles into the ceiling. Valleys are the weak point on these hipped roofs, with rusted valley irons under a layer of leaf litter from the street trees and gums. The suburb sits on the reactive clay of the foothills, so footing movement has cracked pointing and pulled gutters out of fall on many houses. Around Westfield Tea Tree Plaza and the O-Bahn interchange there is a lot of newer medium-density housing under Colorbond, where the problems are more about box gutters and unflashed solar penetrations. Spring hail tracks across the north-east regularly, denting gutters and cracking tiles. The blocks are generous and access is easy, which helps when a full re-roof is on the table.
