Hurricane-force winds can lead to extensive and costly damage to your home. As a homeowner, you should be aware of its impact on your roof. Read on as Genesis Roofing explores the factors that affect your asphalt shingle roof in the event of windstorm damage.
Asphalt Shingle Roof and Wind Interaction
Wind can be unpredictable. It moves randomly – up, down, sideways, and even in circular patterns at various speeds. This is an effect of the temperature and pressure differences in the Earth’s atmosphere as well as the variations of the topography and terrain on the land.
However, the interaction between wind and your asphalt shingle roof is more predictable. First, wind travels up and goes over your roof with changing degrees of uplift pressure. The uplift pressure is highest at the eaves of your roofing system, making them more vulnerable to wind damage. Once the wind reaches the surface of your roof, the suction pressure can lift your asphalt shingles off the roof.
Factors That Affect the Vulnerability of Your Asphalt Shingle Roof
Many factors determine the risk of roof damage. We list a few of them here:
- Location of your home. If you live in a region where high winds frequently occur, particularly hurricane- or tornado-prone areas, your roof may be more vulnerable to damage. Seaside homes, for instance, are more exposed compared to those in the city.
- The geometry of your roof. High-pitched gable roofs with wide overhangs may be unable to withstand wind damage. Four-sided hip roofs, meanwhile, are aerodynamic, making them more resistant to strong winds.
- Age and condition of your roof. Your roof weakens with age. Older roofs with cracked or missing shingles are at a greater risk of wind damage. A roof replacement may be necessary to ensure your home remains durable in the midst of severe weather.
- Improper installation. Misaligned shingles or improperly sealed flashings stem from poor workmanship. This may cause your roof to be more exposed to wind pressure. Make sure you work with a manufacturer-certified roofing contractor when having your roof replaced for your peace of mind.
