How Much Wind Can a Roof Withstand During a Storm?

Nigh modern shingle roofs are rated to withstand ninety mile-per-hour winds, although there are roofing products bachelor for hurricane and tornado-prone areas that tin can withstand winds up to 150 MPH. Yet, the National Oceanic and Atmospheric Administration says that light structural damage – including damage to shingle roofing – starts at wind speeds of fifty MPH.

While there are many reasons why a shingle roof can sustain damage at lower wind speeds, the two most common reasons are an aging roof and shoddy installation. Permit's look at the types of wind damage well-nigh commonly establish with shingle roofs, how you tin can forbid the harm, and how to handle the insurance claim and repairs one time the damage is done.

Common Types of Damage

The most commonly reported types of wind damage to shingle covering are shingles that have lifted and those that either shatter or pull completely free of the roof. Broken, missing and lifted shingles are like shooting fish in a barrel to spot and they require firsthand attending since this type of impairment makes your roof more prone to leaks.

However, at that place is another type of damage that isn't so easy to meet. During high winds, your shingles may lift and and then settle back downwardly in one case the storm is over. When you look at the roof from the ground, it looks fine. But you lot could exist facing two issues:

• The nails holding your shingles may accept loosened, which lessens the roof's power to remain watertight and its ability to resist loftier winds in the futurity.
• Shingles ordinarily take adhesive strips or sealant betwixt each layer so that each shingle seals to the i underneath it. High winds tin can break this seal. Similar loosened covering nails, this makes your roof less wind and water resistant.

Preventing Air current Impairment

To prevent wind damage, i of the outset things y'all'll need to think near are the sealant strips on the backs of the shingles. These strips are meant to bond with the shingles underneath every bit the lord's day heats the roof. If you live in a cool climate or a shady surface area, your roof may not get warm enough to make a proficient seal. Enquire your contractor to use roof cement equally they install the shingles. Two or 3 small spots of cement underneath each shingle increases your roof's wind resistance by a wide margin.

Because the roof's ability to seal itself is dependent on the sun'southward heat, you lot should always install a new asphalt shingle roof in the spring or summer. If you look until fall, your roof will be more than vulnerable to wind harm over the wintertime.

Fantabulous craftsmanship is the final component to a wind-resistant roof. Your contractor should:

• Notify you if the roof deck is weak or rotted because this lessens the deck's ability to hold covering nails.
• Follow the manufacturer'south instructions for shingle placement. Using an incorrect placement pattern may make the roof more than prone to wind damage, and it may besides void the manufacturer'south warranty.
• Ensure that roofing nails are driven properly. The heads of each boom should make contact with the shingle without pressing into the hingle. Nails that are driven in at an angle or driven in too far will damage the shingle, while nails that aren't driven far plenty will allow the shingles to work loose over time.

Dealing with Impairment When it Happens

When high winds impairment your roof, the beginning thing to do is take pictures of the damage. If you suspect that the shingles lifted, telephone call a professional person to audit the roof for broken seals and loosened fasteners.

Most homeowner policies embrace air current harm. On your policy, "Coverage A" is the part that covers damage to your home, so if you have this coverage, you lot should exist protected. Phone call your insurance agent to start the claims procedure. They volition either send an adjuster to your habitation to assess the damage or request that you transport photos of the damage. After that, you'll need to call a contractor to become a quote for the repair or replacement costs.

In the meantime, you lot may need to enquire your contractor to temporarily patch your roof to prevent leaks while your claim is being approved. Brand certain that your contractor adds these costs to your final quote so that the insurance company tin can cover these charges also.

Wind damage is ane of the most common reasons why shingle roofs fail, particularly among older roofs. If you're installing a new roof, make sure that the contractor takes extra precautions and then that you tin avert wind damage in the future.
