Parts Of Your Asphalt Shingle Roofing System A Roofing Contractor Checks For Signs Of Trouble

Posted on: 4 January 2022

When you hire a roofing contractor to inspect your roof, you want the check to be thorough so you become aware of all problems you might have. You may want an inspection before you put your house up for sale, or you may just want an inspection to make sure your roof doesn't have damage that you aren't aware of. Here are some parts of the roof that a contractor checks.

The Structure Of The Roof

Finding water damage to the structure of the roof is important because if the deck or rafters are rotted, the roof might collapse. The roofing contractor can check the deck by walking on it and feeling for bouncy areas that indicate the deck is no longer dry and firm. Plus, the roofer can lift shingles if necessary to get a close look at the roof's structure.

It may also be possible to check the structure of the roof from inside the attic. If rafters are rotted, they'll need to be repaired or replaced. Another time a roof structure needs to be inspected is when you're thinking about putting a second layer of roofing on or when you want to switch to a heavy roof material such as tile or slate.

The Roof Materials

The roofing contractor will also check the roof materials. This includes flashing and shingles. If the materials are damaged, the roofer may want to determine what caused the damage. For instance, curled shingles might be a sign that ventilation is poor and that the asphalt shingles get too hot. Bruises can indicate the roof has been impacted by hail strikes. A loss of granules and metal flashing that's rusted out could mean that your roof is of advanced age and needs to be replaced.

If your roof is fairly new, the roofing contractor wants to make sure the issues with your shingles aren't due to poor installation practices or problems with the way the shingles were manufactured. If either of these problems is found, repairs might be covered by your manufacturer or installation warranty.

The Roof Ventilation

Ventilation is important for your roof, but it's often overlooked until your roof develops a problem such as damaged shingles or ice dams. A roofer can calculate the amount of ventilation that's necessary according to the size of your attic and roof. The roofer can then check your existing vents to make sure they are not blocked and that they are working properly. If poor ventilation is found, the roofer might need to add additional vents so your roof doesn't sustain more damage due to a ventilation problem.
