It is important to flash the outer windows and the doors of your home. This protects your home from getting rain water inside. Flashing around a door keeps the area dry and keeps the building in the best shape possible. Without any flashing around the door, water can intrude the home which can lead to damage from the moisture. Mold can get into your home and the air quality indoors will be compromised without the flashing as well. The cost you will have if you don’t have flashing around the door could be quite substantial, especially if you have to start doing structural repairs to your home because of the water damage.
It is quite common for new construction areas to use flashing during the building process. However, many of the homes which are already built may not have this. It is important to remember two main things when doing flashing around a door. You want to use a water-resistant barrier such as house wrap. You should also use shingle-type membranes so the top portion hangs over the bottom part. This helps the water to drain away from your home or building.
Sometimes you can just install wrap and a drip cap. This type of flashing is done often for doors and windows. However, many building and manufacturer codes require more detailed flashing so the studs, sheathing and interior walls stay protected. Keep in mind that you must plan on how you are going to put flashing around the door before you just jump right into it. You need to use the right materials so that your home or building gets the best protection from any moisture.
