Plano Roofing: Article About How Temperatures Affect Roofs
Many homeowners underestimate the heavy toll fluctuations in temperatures and weather conditions can have on their roofing materials. Plano roofing professionals have seen roofs temperatures climb to an excess of 150 degrees Fahrenheit during the summer. Certain building materials like slate and metal can actually become too hot to touch. During a very cold winter night, roof temperatures can drop below freezing.
In addition to different temperatures, a roof's surface must stand up to different types of precipitation and wind. Hurricane season can bring a mixture of wind, rain and ice. Under this heavy strain, a roof may be subject to failure if it has not received proper maintenance on a regular basis.
Weather will also play a factor in when and if maintenance work can be done. For example, on a hot summer day, jobs like coatings and shingle repairs cannot be done because the roof surface will not respond well because of the high temperatures. The opposite is also true. When the temperature becomes extremely cold, some roofing materials become brittle and can be damage when handled.
Properly installed ventilation can help a roof endure temperature fluctuations better. An effective ventilation system will reduce heat accumulation during the summer and moisture accumulation during the winter in the attic. This takes some of the strain off the roof and increases its lifespan.

A good roof system will have exhaust vents and intake vents. The exhaust vents let the air escape the attic, and intake vents bring in fresh air. It is best if intake vents are situated under the overhangs since this area is always shaded. Most roofers recommend installing intake vents in the soffit. A general rule of thumb is that a home should have the same amount of intake vents as it has exhaust vents. Most would recommend 1 square foot of ventilation for every 150 feet of attic space.
Excessive heat in the attic during the summer, mold growth in the attic or on the roof, water dripping from the tips of nails in the roof and frost growing on the rafters or other places in the attic are signs that a roof does not have sufficient ventilation. Homeowners who are experiencing any of these issues should speak to their roofing contractor immediately to have the ventilation system in their roof evaluated.
The surface of a roof is a harsh environment. For this reason, it is imperative that homeowners take roof inspection, maintenance and ventilation seriously as it plays a direct role on the lifespan of their roof.
