A roof can be damaged from the inside out, with the same devastating effect that a large tree branch brings.
When a homeowner thinks about protecting their roof from damage, they usually are thinking about outside elements such as tree branches, strong winds, ice dams, and heavy snow. While these are valid concerns, a roof also needs to be protected from underneath. A roof can be damaged from the inside out, with the same devastating effect that a large tree branch brings.
A professional St. Louis roofing contractor should be consulted about your home and attic ventilation if you are concerned about the state of your roof. Not only can we repair any damage before it gets worse, but we can also help you properly ventilate the attic space so that no further damage to the roof is caused.
Before a roof can be installed properly, the space directly beneath the roof should be inspected. Whether a large attic or a small crawl space, proper ventilation between the living spaces below and the roof above is critical for the long life of any type of roofing product. Ventilation is required by building code, as well as with roofing material manufacturers who want to ensure that their warranted products are not prematurely damaged by an inadequately ventilated attic space.
How Much Ventilation Is Right for the Space
When it comes to ventilation in your attic, it is possible to have too much. Roofing contractors are trained to determine the happy medium needed based on the size and design of an attic crawl space. Not enough ventilation and you end up with unwanted moisture in the space. Unwanted moisture leads to the beams holding the roof in place being compromised by rot. Once this process begins, the wood rot could spread quickly, putting the entire roof structure in danger of caving in.
You may think the solution is to just add more ventilation to your attic. However, by increasing the number of vents in a roof, you are increasing potential entry points for water. Professional roofing contractors know how many vents are needed in proportion to the size of the attic space and where to place them to reduce the possibility of rainwater getting inside.
Ventilation and Insulation
If your concern is that your heated air is going to blow out through those vents in the winter and raise your energy bills, you are confusing ventilation with insulation. Insulation is primarily used on the floor of the attic space to keep hot air from rising into the attic space in the first place. If you are having energy cost issues in the winter, the amount of insulation you have should be one of the first things you look at. Your roofing ventilation system should have little bearing on how well your home is heated in the winter or cooled off in the summer if the space above your home’s ceiling is properly insulated.
