Roof Flashing Long Island NY | Pro Home Construction

Roof flashing simply put is a think roll of metal. Which is resistant to several weather conditions and moisture. As well as high levels of wind. This can be made of a few materials, such as lead, galvanized steel, aluminum or copper. Then this material is rolled into place, sealed which prevents issues like water damage and mold. Now let us go over what areas of your roof that need roof flashing.

• Chimneys

Roof flashing will seal the intersections of your chimney and the roof, helping prevent any leaks getting through the gap between the two. The flashing slides underneath your roof shingles above the chimney and overlaps the shingle row on the lower side of your chimney.

• Vents

Here the flashing will go underneath the shingles next to the vent. Below the vent the roof flashing should be placed on top of the shingles and then sealed. Just for good measure always make sure you vent cap was put back on top of the vent.

• Skylights

For the most part a continuous piece of roof flashing is used to create the needed seal for your skylight. This prevents water from getting in the cracks around your skylight. Since they usually protrude out from the roof, there will be plenty of space to allow for adequate roof flashing.

There are other features of a home that may require roof flashing. However, these were just some of the ones that we run into the most. Now let’s take a look at some signs of damaged roof flashing.

• Holes

While it may seem like this is an obvious one. Any size hole in your roof flashing will allow water to get into places that its not supposed to be. Causing serious damage to your home and roof.

• Rust / Corrosion

Roof flashing will corrode over time. While certain materials will last longer than others, everything will rust or corrode. When this happens your rusted roof flashing will no longer repel water.

• Internal Leaks

If you are noticing leaks on the inside of your house or around features such as skylights, then there is a chance that your roof flashing could need to be repaired or replaced. We suggest having a roofing come out and look to ensure that the correct repair is done.

• Damage

This includes bends, cracks, dents and worn roof flashing. While these may seem minor, it can break the galvanized coating on the steal or even weaken the structure on the other metals. Once metal is compromised it will become more susceptible to corrosion.
