Hurricane Roofing: How to Prepare Your Roof for Hurricanes

27 de junio de 2024

While you can't control the weather, you can minimize its impact on your home. If you live in a hurricane-prone area, you can take steps before and after a storm to protect your property from damage. For instance, choosing quality hurricane roofing materials and completing proper roof maintenance can help reduce roof damage.

Here's everything you need to know to prepare your roof for hurricane season.

Types of Hurricane Roofing Materials

The Saffir-Simpson Hurricane Wind Scale classifies hurricane categories based on their highest approximate wind speeds:

Category 1: 74 to 95 mph winds
Category 2: 96 to 110 mph winds
Category 3: 111 to 129 mph winds
Category 4: 130 to 156 mph winds
Category 5: 157 mph or higher winds

With this in mind, specific roofing materials are designed to resist high winds and protect against damage from debris.

Tejas resistentes a los impactos

Impact-resistant shingles meet the UL 2218 impact test standards, defending your roof—and home—against the natural elements. They can cost more than typical asphalt shingles but can be worth the expense if you live in a hurricane-prone region.

Techos de metal

Metal roofing can resist heavy impacts and withstand high winds, making it one of the best roofing systems for hurricanes. Some metal roofs can withstand wind speeds up to 150 mph, covering you even during Category 4 hurricanes.

Synthetic Roofing

Synthetic roofing materials resist wind, water, and fire damage, making them beneficial during hurricanes. Since they use man-made materials, they don't rely on a natural build. Instead, they're built with damage-resistant features in mind while mimicking the appearance of natural materials. These composite roofing shingles are typically made from recycled plastic, asphalt, and other products.

GAF Hurricane Roofing Solutions

Your choice of roofing materials can limit roof damage. Some products are manufactured specially to withstand the harshest weather conditions and keep everyone in your home safe. Here are a few GAF products developed with harsh weather in mind.

GAF Timberline® AS II Shingles

Timberline® AS II Shingles are created with proprietary SBS-modified asphalt that's flexible to bolster impact resistance. Impact resistant shingles can be stronger than other non-impact resistant asphalt shingles, and since they pass the UL 2218 impact-resistance test, you could potentially qualify for insurance discounts. Timberline® AS II shingles come with a 25-year StainGuard Plus™ Algae Protection Limited Warranty that protects against algae discoloration. Plus, when installed with four qualifying GAF accessories, they're eligible for the WindProven™ Limited Wind Warranty, which provides infinite wind speed protection.

GAF Grand Sequoia® AS Shingles

Grand Sequoia® AS Shingles also pass the UL 2218 Class 4 test, as they're built with the same SBS-modified asphalt formula. The DuraGrip™ Adhesive seals shingles tightly to prevent wind blow-off, and the shingles are warrantied against winds up to 130 mph, covering Category 4 hurricane winds.

GAF TimberSteel^TM Premium Metal Roofing System

The GAF TimberSteel™ Premium Metal Roofing System gives your home the hurricane-resistant capabilities of metal roofing at an affordable price. The system can help keep your home safe against high winds and rain through its multiple layers of protection. It's designed to provide a beautiful look with GALVALUME® steel that features top and bottom interlocking to keep everything tight and leakproof.

Hurricane-Resistant Roof Designs

More goes into building a hurricane-resistant roof than just the material. The roof shape and slope can provide additional resistance.

Hip roofs can best resist hurricane weather. Although they're typically costlier to build than gable roofs, a hip roof's four slopes provide better wind uplift resistance than a gable roof's two slopes. As the wind flows around the roof causing pressure differences, the additional slopes are better equipped to handle the wind flow.

A 30-degree roof slope also provides the best protection against high winds, preventing wind from easily lifting the roof.

Installation Quality Plays an Important Role

Roofing contractors must follow proper techniques when preparing or installing a roof for hurricane season. This often means using nails instead of staples to install shingles since nails better attach the shingle to the roof and create fewer holes for water to get in. Likewise, properly installed flashing-without gaps in the intersection-helps keep heavy rainfall from entering the home.

Additionally, a contractor can install hurricane clips to ready a roof for harsh weather. These steel plates secure and connect roof trusses to the home's wall structure, keeping the roof attached during high winds. In states like Florida, new homes are required to have hurricane clips installed.

Preparing Your Roof for Hurricane Season

The Atlantic hurricane season starts June 1 and lasts until November 30, reaching its peak in September.

Months before hurricane season approaches, schedule a professional roof inspection from a trusted contractor to ensure your roof is up-to-date and isn't damaged. This gives you sufficient time to complete any maintenance and repairs before the season arrives, as contractors might be busy once it starts.

Reinforce Weakened Areas

A weak spot in your roofing system can lead to further damage and compromise the rest of the roof's integrity. Even a small opening in a shingle can cause serious water damage during a rainstorm. Your roofing contractor can fix or replace loose or torn shingles, repair broken flashing or fascia, clean debris from your roof, and clear out your gutters.

Mitigate Potential Tree Damage

Sharp winds and storms can sometimes cause tree branches to break and fall on top of the roof, damaging shingles or other materials. So, trim nearby trees as part of your roof maintenance. Also, remove fallen leaves before and after storms. Leaves can clog gutters, preventing water from flowing off the roof during heavy rain.

Schedule Post-Storm Inspections

Roofing maintenance after a storm is just as important as before a storm. If a hurricane damages your roof, find a company that handles storm damage roof repair. While you can try assessing any roof damage from the ground, a roofing contractor can accurately identify the damage extent and fix it. They can also help you with any insurance claims if your policy covers you for these circumstances.

Preguntas frecuentes

Can a roof be hurricane-proof?

Due to the nature of hurricanes, no roof is 100% hurricane-proof. But wind- and moisture-resistant roofs perform the best during hurricanes. This is why it's important to choose quality products that will protect your home in the worst possible weather conditions.

What is the best roof for a hurricane?

The best roof for a hurricane is made with impact-resistant shingles or metal. These materials can handle impacts from heavy objects that may blow onto your roof during a hurricane. Metal roofing can generally handle higher hurricane winds better than typical singles.

What type of roof would most likely be torn off in a hurricane?

The worst-performing roofs during hurricanes are ones that have wood shingles or shakes. Wood isn't very moisture-resistant without additional coatings. Wood shingles and shakes are also lightweight, so sharp winds can easily lift them. Furthermore, wood isn't as strong as other materials, so it can become brittle when heavy objects land on it.

What is the best roof for high-wind areas?

Metal roofing is one of the best roofing systems for high-wind areas, as it's built to withstand wind speeds up to 130 to 150 mph. But the installation quality is just as important as the material-even the most robust materials may not stand well against high winds if they aren't correctly installed. Additionally, When installed with the required combination of GAF Accessories, Timberline® Shingles with LayerLock™ Technology are eligible for an industry first: a wind warranty with no maximum wind speed limitation.

If your roof has been showing signs of wear and you've finally decided to replace it, you'll naturally want to know what to expect and how long the process will take. But simply asking a contractor "How long does it take to replace a roof?" won't always give you the same answer.While an asphalt shingle roof replacement on an average-sized home can often be completed in one to two days, many factors can influence how long the replacement actually takes. Here's a look at the steps involved in a roof replacement and the variables that can affect the timing.Securing an EstimateThe first step in any roof replacement project is meeting with your contractor. They'll assess your roof, secure measurements, and review material choices with you. Many contractors rely on technologies like aerial imagery and remote measurement services that allow them to deliver an estimate within a few hours or the next day.After reviewing your estimate and roofing system options, your contractor should have a good idea of how long the project will take (and how much it will cost) based on their past experiences.Accessing Your RoofOnce crews arrive at your home to begin work, they'll need to use ladders or scaffolding to get themselves, their tools, and the roofing materials onto your roof. Complex landscaping, closely situated neighbors, or even a fence around the property can make it more difficult and time-consuming to position dumpsters, stage materials, and dispose of waste.Having to move items around and prepare the space before work can begin can add hours to the front end, potentially causing the project to take longer overall. Accordingly, make sure your roof is accessible and your property is free of hazards before the crews arrive.Discovering Hidden Roof IssuesYour roof replacement includes removing the old roofing system, down to the plywood roof decking. This process is typically accomplished in a few hours. Once the wood decking is exposed, your contractor will be able to see if any water intrusion has caused it to rot.Damaged or rotting plywood will need to be replaced, which can add time to your roof installation-anywhere from a few hours to an extra day.Calculating Your Roof's Size and ComplexityIf your home has a steep pitch-generally greater than an 8:12 slope-the roofing crews will require specialized safety equipment, and they won't be able to work as fast as they could on a lower-pitched roof. Roofs that feature many intersecting planes, angles, and penetrations take longer, as these features require crews to cut more shingles during the installation, adding time to the job.Factoring in Weather on Installation DayIf rain is in the forecast, this could cause your roofing installation to take longer. If the morning weather is clear, but rain is expected in the afternoon, the crews may only complete part of your roof and have to return the next day to finish the installation.Roofers typically start work early in the day. But during cold weather, frost on the roof can make it dangerous. They'll have to take extra safety precautions or start working later in the morning after the frost is gone.All of these environmental factors can impact the roofing crews' ability to work. So, ask your contractor about contingency plans before work begins, and inquire how weather might push the completion date.Improving VentilationVentilation is critical to your roofing system's performance. It prevents moisture from becoming trapped in your attic, which can lead to interior damage to your home. If your contractor determines your home has poor attic ventilation, they'll need to correct that during the roof installation process, adding time to the project.So How Long Does It Take to Replace a Roof?No two roofs are the same, so the best answer to "how long does it take to replace a roof" will vary based on factors specific to your home and location. Start by asking your contractor for a project timeline, and inquire how they'll manage any issues that can cause delays, such as hidden damage or the weather.When you work with a GAF-certified roofing contractor, you can rest assured they have the experience and knowledge to keep your project on track, efficiently handling unexpected delays or other challenges.Interested in getting an estimate on a roof replacement?

If you have trees on your property, you're probably aware of their many benefits. They can boost your property's aesthetic appeal, create privacy, and provide shade to keep your home cooler. Trees can also protect your roof from ultraviolet rays and block wind, minimizing related damage.However, if trees aren't maintained, they can cause damage to your roof. Here are the signs to look for, what to do if a tree falls on your roof, and how to prevent tree damage to your roof in the future.How Nearby Trees Can Damage Your RoofYou're likely aware that the worst damage to a roof can occur when an entire tree falls on your home. This can happen during a severe storm or if an older tree is ill or damaged.However, one tree branch can cause plenty of structural damage, too. Even a small branch falling on or rubbing against your roof can scratch or dent its protective layers, especially if it's laden with snow or ice.And branches aren't the only culprits that can damage your roof. Fallen leaves, nuts, and needles from trees can accumulate, blocking your gutters and roof valleys. This creates an environment that absorbs moisture, leading to moss or mold growth-both of which can reduce your roof's lifespan. Ponding water from this debris can cause leaks over time.Overhanging branches can also create too much shade, exacerbating any moisture issues by making it challenging for your roof to dry. Additionally, branches that touch your roof create easy access for squirrels and other animals, potentially leading to intrusions and damaged roofing components.Signs of Roof DamageTo stop any issues from a tree over the roof from worsening, watch out for signs of roof damage. While a professional inspection can help pinpoint problems by taking a closer look at your roof, you can also perform an inspection from the ground.Look for any cracked, broken, scratched, or curled shingles. Also, note any missing shingles, especially after a windstorm. Check for moss, mold, or an accumulation of debris like leaves and needles. All of these issues can lead to leaks or larger problems down the road, such as structural damage.What to Do If a Tree Falls on Your RoofIf a large branch or entire tree has fallen and damaged your roof or siding, prioritize your safety. If you see any live wires, smell gas, or spot major water leaks, call your utility company right away to shut off your service. Evacuate everyone from your home, and call your insurance company. In most cases, the company will send a professional roofer to evaluate the damage.While you're waiting for the expert to arrive, document the damage by taking photos and video of any areas the fallen tree affected. Once the insurance company has approved your claim, hire a professional to remove the tree and repair the damage.While most homeowners insurance policies cover roof repairs from tree damage, your insurance company might deny your claim if it discovers you failed to do preventive maintenance.How to Prevent Tree Damage to Your RoofProactively addressing tree-related challenges can help you minimize potential roof damage, saving you time and money in the long run.Clear DebrisRemove leaves, twigs, needles, and nuts from your roof and gutters. Installing gutter guards can also help prevent debris from clogging them.Trim BranchesTrim any tree branches that are too close to your roof. Avoid having any part of a tree over the roof-there should be at least 6 feet between your roof and the tips of a tree's branches. If you can't safely trim branches yourself, hire a tree expert.Remove Dangerous TreesIf an arborist determines that more than one-quarter of a tree's limbs need pruning, you might have to cut down the tree before it can fall on your roof. Don't forget to check with local authorities regarding bylaws and protected tree species.Plant Trees at a Safe DistanceIf you're planting new trees, remember they'll grow large over time. So, select species appropriate for your property's size, and plant them about 20 to 30 feet away from your home.Prepare for the Next Storm with Expert HelpAs the saying goes, the best defense is a good offense. Before another storm can threaten the health of your home's roof, take proactive measures to prevent as much damage as possible.For more information about preventing tree damage to your roof, check out GAF storm and hurricane roofing resources.
