Stormy weather, especially wind and rain, can exacerbate current issues with your roof. If you have any problems that need repair, it's a good idea to inspect your roof and have them fixed before storm damage can make them worse.
Curling or Missing Shingles
Shingles that have started to curl are usually doing so as a result of too much moisture. This can happen if rainwater is getting under the shingles, but it can also happen if your attic area is poorly ventilated and hot moist air is being held in for too long. If the curling is minor and isolated, you may be able to simply have the affected area replaced without needing much broader roof work done.
Missing shingles allow moisture into your roof and home much more easily, so if you notice any shingles during your inspection, call for repairs as soon as you can.
Flashing is a component of your roof designed to prevent leaking around things like chimneys and vents. It's usually plastic or metal and sealed with caulk, and is often somewhat visible near where the shingles meet the chimney or vent.
During your inspection, look for signs of rust, corrosion, or cracking and peeling caulk. You can also check the underside of your roof near these areas to look for signs of water damage. If you don't see any signs of leaking, the damage may be minor enough that no water damage has occurred yet; nevertheless, it's a good idea to ask a roofing specialist to investigate it soon just in case.
Discoloration of Ceiling or Walls
You can often spot signs of leaking and water damage from inside your house, even in places that aren't very close to your roof. For example, water damage to the backside of drywall can appear as minor brown stains that might almost look like burn marks. Since water can travel far before settling, these stains can be signs of roof leaks even if they're not directly under the roof.
These stains can sometimes be an indication of plumbing leaks as well, but if you notice these stains in conjunction with other signs of roof problems—such as curling shingles—ask a roofing professional to come check it out.
Rotting Wood in Your Attic
Even serious leaks may not be easy to spot. One such symptom is wet wood rot in your attic and the underside of your roof. Check your attic for any musty or moldy odors, check for cracks in joists and beams, and see if any wood is soft and spongy. Some wood is "soft," but not to the extent that it should give under pressure from your finger. Wood rot can quickly become a very serious danger and weaken your roof even without the stress of a storm, so if you find any, call a roof specialist immediately.
