Maintain Roof Ventilation
When owning a home, we all know the expense of replacing a roof if it becomes damaged. One preventative measured is to make sure that the roof has proper ventilation. Several instances of damage can occur when a roof does not have the ventilation that is necessary to keep it free of dampness.
In most homes, there are small spaces under the roof. The size varies of course, in each house. Water condensation can build up over time from storms, sweating due to humidity, and melting during the winter. When this happens, the water can drip down onto the room below, in the ceiling of that room. If the water condensation is severe, the moisture build up can cause the wood to rot. Rotting of the wood will lead to wet-rot. Even more severe is when the wood begins to dry-rot.
Homes with shingle roofs need to take care in preventing the buildup of water condensation. The condensation can cause severe damage to the shingles; which means the homeowner will be on the roof replacing shingles. Even more costly would be hiring a roofer to replace the shingles. Either way, it will be costly!
The warranty that comes with a shingled roof calls for specific instructions and guidelines for ventilation of a roof. If these guidelines are not followed and adhered to, damage due to improper ventilation could ultimately void the warranty on the shingles. Another reason to ensure that the roof is properly ventilated.
When the space below your shingles roof is improperly ventilated, the shingles will become brittle. Brittle shingles weakens the roof and will allow for other damage due to storms. When the shingles are brittle and weak, it is possible for them to be blown off during a thunderstorm. Hail will cause damage to the shingles as well when they are brittle and weak.
Ventilation of the roof is figured by measuring the square feet of the attic space. It is important to get the measurements correct so as to get the best protection against the element of water. Also, it is important to keep warranties from being voided due to improper ventilation.
The space below your roof, often referred to as the attic space, will also become immensely hot if not ventilated. Heat gathering in the attic space can cause a number of problems. The air conditioner may be forced to work harder due to the amount of heat. This will cause a hike in your electric bill. It is much more cost effective to install the proper roof ventilation in the beginning to avoid some of these disasters.
Accumulation of moisture in the attic space can also cause damage to the structure of the home, not just the roof itself. Water damage can weaken the walls and ceilings of the home. Over time, extreme buildup of condensation can even cause damage to the floors in your home.
Health can be affected by moisture gathering in the attic. Water leakage and condensation built up during the hot weather months can cause certain types of mold. Some molds are dangerous to the respiratory system. People who have asthma conditions can be more adversely affected by certain types of mold in the home. A very important reason to be sure that your roof ventilation is built properly.
Many people purchase older homes. Often, older homes do not have the proper roof ventilation. They were built in a time when there were not any building codes. Also, we did not know the adverse effects then of not having roof ventilation. Generally, they will require additional ventilation. To find out the amount of roof ventilation required for your home you will need to research your local building code for homes. Also, the warranties for shingled roofs come with specific guides that lay out precise instructions as to the proper roof ventilation needed. Remember, to maintain the warranty, you will want to follow the instructions implicitly for the correct roof ventilation.
Ventilation will keep your home’s temperature regulated throughout. Also, the airflow will be maintained by the vents that are installed so as to keep the moisture out of the attic. Another problem encountered when vents are not installed are ice dams. Ice dams occur when the moisture builds up on cold surfaces in the attic space. When the water hits the cold floor or surface, it turns into ice. As each drop of water hits the cold surface, the ice builds up and creates an ice dam.
Most people stay away from their attic spaces in the winter, or any time of the year, especially during the winter. Ice dams are one of the most common occurrences during the winter when improper ventilation is present in the attic. The problem is, when the weather starts warming up, those balls of ice start melting. Then the moisture has set on the floor and surfaces of the attic all winter. Rotting of the wood will start occurring, along with other damage to the structure of the home.
Another component in the attic is the insulation of the home. All of the moisture and heat that builds up can cause severe damage to this insulation. There are various types of vents that can be installed to keep the roof and attic space’s air flowing properly. The expense of ventilating your attic is much less than the damage that will most certainly occur when left to fill with heat and moisture.
