Have you decided to have a local roofing company come to your home to tell you what's wrong with your roof? If so, you're likely curious as to what is inspected during a roof inspection. Here are a few key things that will be investigated to let you know if you're in need of a new roof.
Wear And Tear
One of the first things the roofer looks for is general wear and tear to the surface of the roof. This includes things like holes, cracks, missing shingles, missing granules, and any other signs of physical damage. Shingles with major damage will need to be replaced no matter what, but the overall wear and tear will help determine if a roof needs to be replaced.
There are several signs that a shingle has water damage. There may be edges of shingles that are warping or curling due to moisture exposure. It may be discolored or fading, which is also an indication of weak shingles. You can even have moss or algae growth on the surface as well.
Structural Integrity Issues
The roof and its supporting material must also be in good condition. A key problem to look out for is if the roof is sagging in places since the roof deck underneath should be perfectly flat. Sagging indicates that the roof deck is damaged, and the only way to repair it is to remove the shingles on top.
It's very important that a roof is able to drain properly. This is inspected by looking at the downspouts, gutters, and other aspects of the drainage system to see if it is working. A roofing contractor may even spray water on the roof itself to see if the drainage system is leaking water in places.
Metal flashing is used to wrap around anything that comes out of your roof, such as a vent, chimney, and skylight. The flashing has the job of making sure that water does not get underneath the shingles and causes water to come through whatever object is penetrating through the roof. Any flashing that is no longer flush and can let water in is a big concern.
The roofer will also go into the attic to check the insulation. There not only needs to be enough insulation, but it cannot be wet from a water leak either. Wet insulation will not be able to do its job as effectively as dry insulation and will need to be replaced.
