Your roof is vulnerable to heat damage. Excessive heat can cause your roof to wear out more rapidly and can lead to you being forced to replace your roof sooner. Fortunately, with the right ventilation, your roof will be less vulnerable to this form of damage.
Effect On Shingles
Excessive heat will cause your shingles to shrink and blister. This will lead to you needing to replace your shingles more often. Asphalt shingles are particularly vulnerable because heat rises and can cause extra blisters to form.
Effect On Flooring Joists and Wood Beams
Important components of your roof expand when exposed to excessive heat. When flooring joists and wood beams expand, they can damage flashings and will make it more likely for moisture to enter your roof.
Effects Of Humidity
Heat contributes to humidity and can cause roof decking and shingles to become damaged. Also, humidity causes mold to grow, and this can be dangerous to your family's health. The moisture can cause plywood layers to separate and cause further damage to your roof.
Effects On Flat Roofs
If you have a flat roof, the damage done to your roof from excessive heat might be less noticeable, but it still occurs. You may see leaks form on your roof, which can allow moisture to enter and cause damage. Because damage is harder to identify, you should hire a roofing contractor who is able to inspect your roof and determine whether it is damaged and what should be done to correct the problem.
Installing Vents On Your Roof
When you're ready for a roofing contractor to install vents on your roof, make sure to understand the different types of vents you will need to install. Roof vents prevent premature aging and other forms of roof damage by allowing hot and moist air to escape the attic. Ridge vents make sure that the underside of your roof stays ventilated. Intake vents allow for adequate air circulation.
Fortunately, roof vents can be installed on already-existing roofs. You will need to have a hole cut in your roof where the vent will go. Then, you will need to install the roof vent and flange. You are best off having this job performed by roofing contractors because performing work on the roof can be dangerous for someone who is untrained and you may cause moisture to enter through the vent if it isn't installed properly.
