ASPHALT SHINGLES AND WIND RESISTANCE

The roof protects the inside of our home from inclement weather and from other outside elements. A solid roof system keeps us safe from strong winds outside.  It keeps us dry when it is raining.  It provides shelter from heat on a hot day.  Therefore, it is very important that we also protect our roof so it can protect us.  In particular, we will talk about asphalt shingles and wind resistance in the Philippines.

The roof is the cover of our home.  As such, it is located at a very vulnerable position.  More importantly, it is exposed to the violence of typhoon winds.  Violent winds can cause sudden roof damage when a strong typhoon passes through. However, asphalt shingles can also be adversely affected even on a normal windy day.

Always being prepared against unpredictable winds is the best defense.  You must concern yourself with your asphalt shingles and wind resistance.  This article talks about the potential roof damage from wind on your asphalt shingle.

 

THE INTERACTION BETWEEN WIND AND YOUR ASPHALT SHINGLE ROOF

Wind moves in unpredictable and random patterns.  Therefore, wind does not always move in a steady, constant direction.  It is an effect of temperature and pressure changes in the Earth’s atmosphere.  Moreover, it is also a result of the land’s terrain and topography.  As a result, wind swirls up and down, moves sideways, and performs circular patterns at different speeds.

However, the interaction between your asphalt shingles and wind resistance is more predictable.  Wind travels up towards your roof when it hits the sides of your home.  In addition, it goes over your roof with changing degrees of uplift pressure.  Therefore, uplift pressure is highest at the eaves of your roof.  These areas are particularly vulnerable to wind damage.  More importantly, once the wind travels the surface of the roof, suction pressure can lift your asphalt shingles off.

 

FACTORS THAT AFFECT ASPHALT SHINGLES AND WIND RESISTANCE

Several factors influence the speed and direction of wind and how it affects your asphalt shingles:

  • Roof Layout. In general, roofs with higher slopes, longer gable lines, and wider eave overhangs are more susceptible to wind pressure.
  • Location of your Home. Stronger winds are expected in areas that are typhoon-prone.  For example, seaside homes are more exposed compared to those in the city.
  • Quality of the Plywood Decking. Local generic plywood is notoriously known for poor quality that will not last over time.  Invest in quality plywood that will survive wear and tear.  In particular, as the plywood rots, the nails that fasten the shingles may become loose.
  • Quality of Nails. Ensure that your nails are of the highest quality.  The integrity of your asphalt shingles will be only as good as the quality of your other materials.
  • Poor Installation. Scrimping on nails, misaligned shingles, improperly sealed flashings and poor workmanship will all cause your asphalt shingle roof to be more exposed to wind pressure.

ASPHALT SHINGLE DAMAGE FROM WIND PRESSURE

Caring and maintaining your asphalt shingles will require to have your roof checked regularly.  In particular, we will want to check the roof after a typhoon.  Accordingly, you will want a trusted roofer such as KAWARA Philippines to help you with the care and maintenance of your roof.  Accessing the roof has its own set of risks.  It would be best to leave it to a professional.

We need to check the roof for damage from fallen tree branches and other debris.  We will also need to see if there are portions where shingles or flashings were blown off.  However, some signs of damage may not be as noticeable.  For instance, there may be areas where the shingles look slightly raised.  This is an indication that the seals are broken and this exposes the entire roof to further damage.  This will need to be repaired immediately. Consequently, proper care and maintenance will increase the strength of your asphalt shingles and wind resistance.

 

BP CANADA WEATHER-TITE® TECHNOLOGY

Surface uplift can leave shingles deformed and prevent them from properly sealing. Water, dust, and debris that find their way across a sealant strip can also render the seal ineffective. In both instances, the shingle is left exposed to wind-driven water infiltration and wind blow-off. That is why it is crucial that the adhesive seals off quickly after the installation.

BP Canada’s patented Weather-Tite® Technology improves the sealant itself and the way it is applied on the shingles.  Consequently, the result is a sealing mechanism so efficient that it allows protection against winds of up to 220 kmh.

Weather-Tite® Technology has been an industry standard for a decade now. It is the primary reason why BP Canada offers the highest wind warranties in the Philippine market.  Nails may fix the shingles down, but it’s the sealant that keeps them in place in the long run.  Hence, it is the best shingle brand for beach houses that are exposed to strong winds.

When wind lifts the exposed portion of a shingle, dust and other impurities can contaminate the sealant.  This prevents the shingle from sealing properly. Wind then moves up the roof and lifts the exposed part of the shingle, making it curl. Once released from the wind, the shingle will remain slightly deformed, which will also hinder its ability to seal. Only properly sealed shingles can protect your home from water infiltration.  Therefore, Weather-Tite® Technology ensures the care of your asphalt shingles and wind resistance.
