I. Skylights – When you cut some holes on roof to put skylights in, the natural waterproof tendency of roof are despoiled. Some skylight installations cause leaks in roof. It is mostly due to poor selection of skylights and improper installation.
II. Broken Tiles – Broken roof tiles causes severe roof leaks. The tiles do not break often but overhanging trees, falling woods breaks the tile. Tiles are very fragile and little pressure of anything can break tiles easily. The breaks results in leaks into roof.
III. Rusty Valleys – Rusted valleys on roofs are one more reason of roof leakage. The old rusted valleys bring such problems after survival of 20-30 years.
IV. Defective Tile Ridge Capping – The pointing under tile ridge capping break over time and then water leaks into the crack.
V. Chimneys – It is another hole on roof which needs proper installation and waterproofing. The flashings around chimneys cause leaks and the pots break.
VI. Faulty Flashings – The edges of roofs must be waterproofed by flashings to stay longer. If your roof is new and it’s leaking then your roofer surely did a mistake in its installation.
VII. Rusty Roofs – Rusty roofs are surely an obvious reason of leak. But it takes much time to know whether roof begins to rust and when holes form and when water starts leaking. A close inspection by the roofing experts can reveal the actual situation of your roof.
