4 Subtle Signs Your Old Shingled Roof Is In Danger Of Leaking

Posted on: 25 May 2017

At first glance, you may not see any damage to your home's shingled roof. However, you may still wonder if the old roof has sustained damage that is not immediately visible. If so, look for the following subtle signs that your old shingled roof may be in danger of starting to leak.

Test Shingles From Different Areas On Your Roof

One sign that your shingles may start breaking and letting water into your home is their pliability. Over the years, temperature changes and constant exposure to the sun can make them dry and brittle. One way you can see how pliable they are is to test them.

After taking the necessary safety precautions, climb up onto your roof. Then, slightly bend the corner of one shingle. If it bends smoothly with no cracking, the shingle is still good.

However, if you hear or feel it starting to crack, let loose of it before it breaks. This means the shingle has become brittle. Do not try to bend too much of the shingle in case this does happen, as it could damage the shingle to the point it needs replacing.

Repeat the test above with various shingles in different locations on your roof. If the majority of them are brittle, you may want to hire a roofer to have them look to see if the problem is localized or widespread, necessitating roof replacement.

Check Your Gutters For Shingle Pieces

If you don't find any obviously damaged or brittle shingles, check your gutters for pieces. During strong rains and winds, pieces of the shingles may be broken loose and carried down the roof. Once in the gutters, they can become stuck inside, especially if there are leaves and other debris present.

After checking your gutters, you should also check the ground beneath your drain spouts. Some of the pieces may have been washed out of the gutters and down the spouts, where the broken shingles may still be laying.

Inspect The Shingles For Nail Holes

Over the years, the nails holding the shingles onto the plywood become loose. Eventually, the nails can work their way out. leaving holes in both the shingles and the underlying structure. These holes can provide a free entryway for water. Not only can it rot the plywood under the shingles, but it can also cause water damage in your home.

Inspect as many shingles as you can to see if they still have nails in them. If you do not see a nail, check for a hole. If possible, try to replace any missing nails. However, if the hole has become too large for a nail, you may need to have a roofer look at both the shingles and plywood to determine the extent of damage.

Look For Gaps Around The Flashing

Whether or not you find brittle or broken shingles, you should also check the flashing around your vents and chimney. This flashing directs water away from these structures and down the roof so that the water does not leak into your home through any holes around them.

The top of the flashing should be flush with the vents and chimney. There should also be no signs of buckling or rust. However, if you do find that the flashing has been damaged or has left gaps around the structures, water could already be leaking into your home. You may want to contact a roofing contractor to replace the old flashing.

If you find one or more of the signs above while inspecting your roof, you may be facing an imminent leak problem. You may want to contact a roofing contractor to have them professionally inspect your shingles
