After a storm damages your roof you can end up with more than roof damage. Water enters through the missing shingles and that roof leak will damage your ceiling.
Making sure the proper repairs are made is necessary to prevent mold and additional costly future repairs.
Before you do anything, get a tarp for your roof right away. Water damage can be some of the most costly repairs and get much worse with continued exposure. Making temporary repairs and completing the proper dry out is the first step.
If the water is entering and creates a bubble on the ceiling you want to get a bucket and towels placed under it, then pop the bubble with a nail. This will create an opening for the water to exit so the drywall does not get so saturated that an entire section of ceiling comes down. Do not worry about the ceiling being damaged, it was already damaged by the water.
After you have installed a tarp and have stopped the water, if you can, cut out the damaged drywall. This gives access to remove the wet insulation above it. You will want to wear safety glasses as dust and debris will fall on your face as you cut the drywall. You can purchase a drywall knife at any local hardware store. You don’t need to cut too big of an area, just the portion that is brown or has the large bubble.
Remove and dispose of the drywall and any wet insulation. You can cover the hole up with plastic so your air conditioning does not escape up into the attic area.
Take pictures of the ceiling damages before you do this so you have them for your insurance claim adjuster. Do not schedule any permanent repairs until the adjuster has been out and permanent roof repairs have been made. There is no reason to fix the inside until you are 100% sure it will not leak again.
Mold grows in warm, dark, wet places. So by removing all the wet material and drying out the area, you are removing an area for mold to grow. You can also spray the framing and the surrounding areas with 10% bleach 90% water mixture. This will kill any mold spores left in the area.
Now you can rest easy knowing you have done everything you can to prevent long-term damage. There are water mitigation companies that specialize in doing this work. These professionals will also bring out dehumidifiers and fans to help with the dry out. They can be found under Fire Damage in the phone book.
