The short answer
Check the Exterior
Start by walking around your home and looking at the roof from the ground. Use binoculars to spot missing, cracked, or curled shingles. Storm winds can lift edges or tear off entire sections, especially at corners and ridges. Also check for loose or dented flashing around chimneys, vents, and skylights.
Look at the gutters and downspouts for granules from asphalt shingles. A heavy buildup means the shingle surface is wearing away. Check for dents or punctures from hail. After any severe storm, inspect the roof for new damage.
If you have a metal roof, look for popped seams or screws, and check for dents that can create low spots where water pools. For flat or low-slope roofs, inspect the membrane for tears, blisters, or ponding water that lasts more than a day.
- Missing or lifted shingles
- Granules in gutters
- Dented or punctured metal
- Loose flashing
- Daylight visible through the roof deck
- Sagging or uneven roof lines
Inspect the Attic
Go into the attic with a flashlight and look at the underside of the roof deck. Check for water stains, dark streaks, or rot on the wood. Also feel the insulation for dampness. Brown or yellow stains usually mean active leaks, while white or gray marks may be old water damage.
Look for light coming through the roof. Even a small crack or gap can let water in during heavy rain. Check around vents, pipes, and chimney bases for dampness or staining. Also inspect the rafters and decking for soft spots, which indicate prolonged moisture exposure.
- Water stains on rafters or decking
- Musty odor
- Visible mold or mildew
- Damp insulation
- Soft or rotting wood
Look Inside Your Home
Water from a roof leak often travels down wall cavities before it shows inside. Look for bubbling or peeling paint on ceilings and walls, especially near exterior walls. Brown or yellow rings on ceilings are classic signs of a roof leak.
Feel the walls and ceiling for dampness. Use your hand to touch areas near windows, corners, and where walls meet the ceiling. Dampness or a cool sensation may indicate hidden moisture. Also check for warped or stained drywall, which can sag or crumble if wet.
Inspect the attic access panel and the ceiling around it for stains. If you have a finished attic, check the seams and edges of the ceiling. Also look at the baseboards and flooring for water damage that could come from a leak above.
- Brown or yellow ceiling stains
- Peeling or bubbling paint
- Warped or sagging drywall
- Damp patches on walls
- Water spots near light fixtures
Know When to Call the Pros
If you spot any of these signs, it is wise to act quickly. Water can travel far from the original leak, causing damage to insulation, framing, and drywall. The longer you wait, the more extensive the damage can become, and the higher the repair cost may be.
A local water damage pro can perform a thorough inspection and identify the source of the leak. They have the tools and experience to assess the roof condition and the extent of water damage. They can also help with drying and mitigation to prevent mold growth.
If the damage is widespread or you cannot safely access the roof, professional help is appropriate. A roof repair specialist can address the roofing issue, while a water damage pro can handle the interior cleanup. Do not attempt to climb on a steep or damaged roof yourself.
Prevent Future Storm Damage
After a storm, trim overhanging branches that can scrape or fall on the roof. Keep gutters clean so water flows freely. Check the roof after every major storm, not just in spring or fall. Regular checks are useful in any climate with heavy snow or thunderstorms.
If you have insurance, review your policy to understand what storm damage is covered. Policies vary, and your insurer decides what is covered. Document any damage with photos and notes, and contact your insurance company promptly to report the loss.
Consider scheduling a professional roof inspection once a year, especially before winter. A pro can spot weak spots that you might miss. They can also recommend repairs that help your roof withstand the next storm, such as re-sealing flashing or replacing worn shingles.

How soon should I check my roof after a storm?
Check as soon as it is safe to do so, ideally within a day or two. Water damage can worsen quickly, so acting fast helps limit the extent. Look for visible signs from the ground and in your attic, and call a pro if you suspect a leak.
Can a roof leak cause mold?
Yes, a roof leak can lead to mold growth. Moisture in dark, warm areas like attics and wall cavities creates ideal conditions. Mold can spread within 24 to 48 hours. If you see or smell mold, consider contacting a mold professional for safe removal.
What should I do if I see water stains on my ceiling?
First, place a bucket under the stain to catch dripping water and remove any furniture. Avoid touching the ceiling if it is sagging. Take photos for your records. Then contact a water damage pro to find the source and begin drying and repair.
