Once again you could actually have a good roof and wind will drive water up and under your roofing materials. Poorly anchored off ridge vents can flip up and be come scoops that direct large amounts of wind driven rain into the attic figure 11. Some vents are also prone to leaking when winds blow from certain directions. The only means of prevention is to install membranes under the roofing.

This will stop the rain getting under and causing roof leaking by wind driven rains. Wind driven rain can also be a major problem. It this is the case you need to create a breathable shield to slow the driving rain drops while still allowing air flow. Fortunately wind driven rain is a rare occurrence.

Roof vents can let hurricane driven rain into an attic because most vents are not designed to resist hurricane forcefully driven rain. Wind driven rain will batter your roof and water will escape through any cracks no matter how small they are. No leaks in any other rain situations only wind driven rain. Often a roof can be in perfect condition but because the wind drives the rain across and upwards it can get under the eave and under the roof.

In reality it might not be your roof but it could be a broken water pipe or even faulty head flashings. In this situation there s no harm to looking around for leaks. Hairline cracks in tiles or splits as they are sometimes called cause leaks too. Hemming the edges of the roof means bending the underneath to an angle of 180 degrees.

In that path it passes vents on the roof. The trouble is it is difficult to find the cracked tile without putting up a ladder and having a good look. The leak is definitely only when rain is accompanied by winds strong enough to make the rain horizontal rather than vertical. The causes of a leaking roof can range from wear and tear to roof leaking by wind driven rain.
