Five Signs Of Roofing Trouble That Show Up Inside Your Home

When you want to tell what kind of shape your roof is in, your first instinct is probably to go outside and look at the roof. Indeed, you can see a lot of signs of roof trouble, like peeling shingles and loose flashing, from the outside. However, there are also a lot of signs of roofing damage that you can look for inside your home. Here's a look.

Sagging Doorways

Pay attention to the doorways in the upstairs of your home, especially. If they begin sagging, making it hard to open and close your doors, then you may have a major issue with your roof. When the wood that forms the base of your roof starts deteriorating, pressure sometimes gets redirected elsewhere, causing ceilings and doorways to sag. Call a roofing contractor immediately if you notice this problem since, in rare cases, it is sign your roof may collapse.

Moisture in the Attic

Not all roofing leaks are caused by missing shingles. Water can leak in around a nail or under flashing even though your roof looks fine from the outside. So, go up into the attic to assess for moisture. If you see any little puddles of water or your insulation feels moist in some areas, you probably have a leak. These symptoms will be most noticeable, of course, after a rain storm.

Water Marks on Ceilings

Look up at your ceiling in the upstairs of your home. Do you see any spots where the ceiling is discolored? These are usually caused by water leaks. If it has not rained in a while, you may just see some dry, brown marks -- but no moisture in the attic. Have the roof looked at it before it rains again.


If you have mysterious mold appearing in your attic or on the ceilings of your top floor, it is probably due to a roof leak. Mold does not appear without moisture, and plumbing leaks, the other major cause of mold, don't typically explain attic or top-ceiling mold growth since pipes don't usually run through these areas.


If you can see nails coming through the boards that form the top of your attic, then you can expect roof leaks to occur. Nails should be sized so that they don't extend all of the way through the roof; if they do, they should be replaced before water starts seeping in around them.
