Why Flashing Occurs on the Roof
There are different kinds of flashing that can occur on the roof. There is continuous, base, counter-flashing, and step flashing. Continuous flashing, also known as apron flashing, is when the long metal piece that pushes the water down the shingles has issues flexing. Base flashing is when a counter-part of the roof such as the chimney needs two parts of flashing. It guides the rain to that part of the roof that is flashing which is a good thing. Counter flashing mixes base flashing and above base flashing. Step flashing is a rectangular piece that directs the rain to flow away from the wall.
Some additional flashing that can occur is skylight, valley, drip, and kick-out flashing. Skylight flashing might require a professional to make that special piece. Valley flashing is when a piece of metal flashes to protect a vital area of the roof. Drip edges is a metal piece that flashes on the edge of roof which guides the water off the roof without destroying the house or leaking. Kick-out flashing bridges the step flasher and gutter. It also guides the water in the gutter.
The Price of Roof Repairs
The pricing of the roof depends upon the type of roofing. If it is asphalt it is $120 per 100 square feet. If it’s slate it costs $800-$1000 per 100 square feet. If it is tile the pricing is $300-$500 per 100 square feet. If the roofing type is metal it is $1500 per 100 square feet. The type of roofing that needs to be done really depends on the city permits and what is allowed to be fixed and what can’t be added on or altered. The best advice would be to receive three different quotes before deciding which roof repair company to go with.
