Residential Metal Roofing: Is It Right for Me?

When the contractor delivered the sad news that my roof needed replacing, that led to a discussion of material choices. I was surprised to hear that metal roofing was an option. Sure, it was fine for commercial buildings, but a home? My contractor told me that metal is used for homes more than people realize. The panels can be designed to look like just about any type of roofing you can imagine. After looking at some samples and finding out about the long life of metal roofs, I decided to give it a try. Fifteen years later, my roof is still in great shape. If you are facing a roof replacement in the near future, let me tell you more about metal roofing. I'm betting that you'll decide this solution is right for your home.

The 3 Roofing Problems Causing A Kitchen Vent Hood Water Leak

by Kelly Murphy

If water is dripping onto your stove through the vent hood when it rains, then there are three different roofing problems that can cause this condition:

  1. a leak in the flashing around the vent
  2. a damaged roof vent
  3. a stuck vent flapper

While it is always possible your home has a roofing leak and it just happens to be dripping down into your kitchen, it's more than likely one of the three reasons listed above. 

Here is more information on each of these problems and how a roofing company could fix them:

1. A Leak in the Flashing Around the Vent

All roof vents have metal flashing around them to prevent leaks and connect them to the surrounding shingles. Flashing is held in place with sealants, which sometimes degrade in the weather. When this happens, the flashing will leak. 

To fix leaking flashing, a roofer will remove the existing flashing, apply a new layer of sealant, and then put the flashing back in place. If the flashing itself is damaged, then it will be replaced.

2. A Damaged Roof Vent

Roof vents are made of either metal or thick plastic, and they are subject to damage from flying objects as well as aging. If the roof vent itself is damaged, then water will leak into it and drip down into your kitchen. 

To replace a damaged roof vent, a licensed roofer will remove the flashing around the existing one, remove the vent, and then replace it with a new one. Once in place, the new vent will be flashed and sealed to prevent future leaks.

3. A Stuck Vent Flapper

The roof vent for your range hood has a flapper installed on top of it. The purpose of the flapper is to keep rainwater out of the vent hood below when there is no steam rising out of it. Sometimes when it rains really hard or the winds are very strong, the flapper will get stuck in the open position. With the flapper stuck open, rainwater gets into the vent and runs down into your kitchen's vent hood.

To determine if the flapper is damaged or if the situation was temporary during the storm, you can check out the vent safely from the ground using a pair of binoculars. If the flapper is sticking up on the top of the vent, then you will need a roofer to come repair or replace it. Thankfully, this is a very inexpensive roofing repair.
