The short answer

Check from the Ground First

Walk around your home and look at the roof from different angles. Use binoculars if you have them. You are looking for shingles that are curled, cracked, or missing entirely. Also check for any shiny spots where the granules have worn away, since that exposes the underlayment to the weather.

Look at the flashing around chimneys, vents, and skylights. Storm winds can lift or bend flashing, leaving gaps where water can sneak in. Check the gutters and downspouts for an unusual amount of dark granules. Those granules come from your shingles and are a strong sign that the roof took a beating during a storm.

Inspect Your Attic for Leaks

Go into your attic on a dry day and bring a flashlight. Look at the underside of the roof deck for dark streaks, water stains, or damp spots. Pay close attention to the areas around nails and seams. Even a small stain can mean water has been seeping in for a while, and hidden leaks can rot the wood over time.

Feel the insulation for any wet or clumped sections. Wet insulation loses its ability to keep heat in and can also become a breeding ground for mold. If you find damp spots, trace them upward to see where the water might be entering. Mark the location with a piece of tape so you can show a professional later.

  • Dark or black streaks on the roof deck
  • Water stains on rafters or trusses
  • Damp or clumped insulation
  • Rusty nails or metal flashing
  • Sunlight visible through small gaps
  • Musty odor that was not there before

Look for Interior Water Marks

Hidden roof damage often reveals itself inside your home before you ever see a leak. Check the ceilings on the top floor for brown or yellow rings, bubbling paint, or sagging drywall. These marks can appear days or even weeks after a storm, so keep an eye on the same spots over time.

Also inspect the walls near the roofline and around windows. Water can travel along framing and show up far from the actual entry point. If you see any discoloration or feel a soft spot in the drywall, that is a sign that moisture has been sitting there. Do not wait for the stain to grow before you take action.

Know What Recent Weather Did

Think about the storms that have passed through your area in the last few months. Hail, high winds, and heavy rain can all cause damage that is not obvious from the street. Your local weather patterns matter, since the humid subtropical climate with a Gulf hurricane season can bring strong storms that stress your roof.

The age of your roof matters too. Older shingles are more brittle and more likely to crack or lose granules during a storm. If your roof is near the end of its expected life, even a moderate storm can cause hidden damage. Keep a mental note of when the roof was installed and how severe the recent weather has been.

When to Call the Pros

If you spot any of the signs mentioned above, do not wait for a visible leak to appear. Water damage can spread quickly through insulation, drywall, and wooden framing. Local water damage pros can do a thorough inspection of your roof and attic to find the source of the problem. They have the tools and experience to spot damage that is easy to miss.

A professional inspection usually covers the roof surface, flashing, gutters, and attic. The pros may also check for moisture in the walls and ceilings using specialized equipment. This kind of assessment helps you understand the full extent of the damage before you decide on repairs. Acting early can save you from much bigger problems later on.

  • Visible water stains on ceilings or walls
  • Missing or lifted shingles after a storm
  • Granules collecting in the gutters
  • Damp spots or musty smell in the attic
  • Sunlight coming through the roof deck
  • Recent hail or high wind events in your area

Frequently asked questions

How soon after a storm should I check my roof?

You should check as soon as it is safe to go outside. Walk around the house and look for obvious damage like missing shingles or fallen branches. Then check the attic for any new stains or dampness. Acting quickly helps you catch small problems before they turn into big ones.

Can I find hidden roof damage myself?

You can spot many signs yourself, like water stains, granules in gutters, or curled shingles. But some damage is only visible from the roof itself or requires moisture detection tools. If you suspect a problem, it is wise to have a professional inspect the roof and attic more thoroughly.

What should I do if I find a leak after a storm?

First, move furniture and valuables away from the leak and place a bucket underneath to catch dripping water. Then take photos of the stain and the surrounding area for your records. Contact the pros to assess the situation and help stop further damage. Do not ignore it, as even a small leak can worsen.
