All about Roofing Nails for Shingles

If you notice missing shingles on your roof, there's no need to panic. Missing shingles aren't an emergency, but you should still act quickly, especially during wet seasons. Your roof is a multilayered system designed to protect your home's structure and finishes from water damage.If you ignore missing shingles, moisture can get into your home, leading to issues such as rot, mold, and costly water damage. Replacing missing shingles quickly can mean the difference between a minor roof repair and a total roof replacement.So, here's how to spot missing shingles and hire a roofer to replace them.How to Spot Missing ShinglesLocating missing shingles, before leaks set in, can save you time, money, and peace of mind. Here are several ways to spot them before they cause bigger issues.Inspect Your Roof from the GroundScope your roof with binoculars for signs of missing shingles. Inspecting your roof from the ground helps prevent shingle damage from walking on the roof and, most importantly, fall-related injuries. Scan your roof from every angle that it's safe to do so, including from streets, sidewalks, and neighbors' yards if you have permission to do so.Check for Shingle ChangesSystematically check each shingle following a horizontal or vertical line. A missing shingle often sticks out as a color change in your shingle pattern. While you're at it, look for shingles that are cracked, curled, or sagging or that aren't aligned with the others. These can all be signs of shingle or roof damage.Review Your Roof for Damage after StormsRoof damage often happens as a result of extreme weather. Once it's safe to be outdoors, visually inspect your roof for damage. You can also survey the ground around your property to spot any shingles that may have blown off.Look Inside Your Home for LeaksCheck inside your home for longer-term signs of missing shingles. Evidence of leaks in your attic or water stains on your interior ceilings or walls can indicate wider-spread water damage in your home. If you notice anything out of the ordinary, have a roofing professional inspect the area (both inside and outside) for damage.Schedule a Professional Roof InspectionThe National Roofing Contractors Association recommends professional-level roof inspections twice a year—once in the spring and once in the fall. Like routine car maintenance keeps repair costs down, roof inspections can help spot small concerns before they potentially become expensive problems.How to Hire a RooferOnce you spot missing shingles on your roof, the next step is hiring a professional to replace them. Create a list of questions before you call around, so you can find a reliable roofing company that won't cut corners.If you have warranties, you may also want to check whether or not those have any requirements. For example, all GAF roofing shingles and qualifying accessories (the "GAF Products") come with the coverage provided by the GAF Shingle & Accessory Limited Warranty,** and you don't need to do anything at all to get it.How to Prepare for Roofing RepairsThough every contractor is different, confirm certain details before signing any contracts. Here's how you can ensure you and your contractor are on the same page before work begins:Communicate clearly from the start; this will help prevent frustration and unexpected costs.Before making a deposit, be sure you both agree on the quote and job details.Agree on the job's start date, plus a contingency plan if bad weather forces a rain check. Ask your roofer if they'll install a temporary tarp to prevent water damage in the case of a delay.Read your quote carefully. Confirm approximate labor costs and the color, style, and brand of shingles that will be installed.Ask about anticipated material quantities and estimated roofing material costs (like flashing, roofing nails, etc.).Confirm whether the repair job includes cleanup costs and if the roofer will remove any debris.When to Consider a Roof ReplacementLook at the big picture before replacing missing shingles. Consider your roof's age, any warranties on your roof system, the extent of the roof damage (both internally and externally), and whether the missing shingles are an isolated issue. Multiple missing shingles or frequent repairs could be a sign that you need a new roof.Ready to schedule a professional roof inspection?

A low-slope commercial roofing system is responsible for keeping the elements out of the building. During heavy rain, water with nowhere else to go may pond on the roof. A roof drain prevents water from ponding by providing a way for it to leave the roof, and regular commercial drain maintenance ensures its continued performance.Although commercial buildings may appear to have flat roofs, some roofs have slopes built into the structure or require added slopes, typically achieved with tapered insulation to facilitate water drainage. This slope is designed to guide water to a drain, so it doesn't sit on the roof and damage the roofing system or structure. Standing water can slowly deteriorate certain roofing materials and cause premature degradation, failure, or damage. It can also promote algae and plant growth and attract nuisances such as birds and insects.Guiding Water off the RoofResidential roofs have gravity on their side—water flows down the slopes into gutters that transport it away from the home. Commercial buildings with low-slope roofs have to work a little harder to remove water, which is where roof drains come into play.The roofing system design can help guide water toward the drains. It often involves using tapered insulation such as GAF EnergyGuard™ tapered polyiso insulation. The two most popular tapered boards deliver a 1/8-inch or 1/4-inch per foot slope. This slight slope prevents water from standing on the roof, forcing it toward a drain strategically installed at various low points on the roof with crickets and saddles.Drain placement is particularly essential when the parapet wall sheds water. To help water arrive at the drain line or gutter, tapered crickets are typically installed in corners and between drains to direct the flow and alleviate ponding. This water must flow down the roof side of the parapet wall and follow the roof slope to reach the drain.3 Common Types of Roof DrainsInner DrainsInner drains are connected to sloped pipes under the roof that carry water off the roof and away from the building. They typically rely on gravity and the roof's slope to get water to the drain.ScuppersScuppers are found at the roof's edge, usually installed through a hole in the parapet wall. They're designed to drain water from the roof into a downspout or may extend out from the building to shed water.Siphonic DrainsSiphonic drains feature a baffle that keeps air out and allows water to fill the pipes. Once the pipes are full, the lack of air creates a vacuum that siphons water from the roof at a high velocity. The baffle also keeps leaves and debris from gathering in the drain and causing a blockage.Caring for and Maintaining Roof DrainsInspecting and maintaining roof drains should be part of your regular roof inspections. Because roof drains are located at low points on the roof, it's easy for debris or leaves to build up in these areas. Clearing debris is essential for the drains to function properly. Clogs encourage pools of water to form on the rooftop, which can cause structural issues for the building. Even just an inch of standing water can add thousands of pounds of weight to the roof, reinforcing the need for regular commercial drain maintenance.Advancing Roof Drain Maintenance with TechnologyGAF recently introduced the Steely Drain™. This is a roof drain solution that leverages technology allowing contractors to build their maintenace relationship by setting up building maintenance reminders to contact building owners or facility managers. This contractor-inspired drain is made of 316L marine-grade stainless steel, making it ideal for tough environments that require exceptional corrosion resistance.Steely Drain™ features a QR code etched onto the top that you can scan with your smartphone to instantly view information about the roofing system. This data can include the contact information of the contractor who installed the system, the architect and consultants for the project, and the roofing system details if all information is inputted.This critical data is managed from a convenient GAF-hosted dashboard and plays an important role in the roof's maintenance plan. Contractors can set up and receive email reminders when it's time to perform scheduled roof and drain inspections. The dashboard also eliminates the need for core cuts since every detail of the roofing system is available through the QR code—from the deck type to the cover board, underlayment, insulation type and thickness, to the final membrane.Knowledge Is Key to SuccessWhen properly installed and maintained, roof drains can keep the rooftop free of standing water for many years.

You can also visit the GAF CARE Contractor Training Center to gain additional tips and access valuable training courses that allow you to learn at your own pace.

As a roofing contractor, you know how noisy roofing projects can get. And when repairing or replacing roofs on institutional properties, like schools and healthcare centers, it's often not possible to remove occupants during the project's duration.Accordingly, minimizing disruption at these facilities is key, as students need to be able to concentrate and patients must be protected as they recover. Here are common disruptions to consider and how to reduce them, with insight from GAF Building and Roofing Science Research Lead, Elizabeth Grant.Common Disruptions on Construction SitesYou have several challenges to consider when working on schools or other facilities with ongoing operations, including noise, odors, and occupants' safety.Elevated VolumeHeightened noise levels can affect both students and patients. At schools, loud sounds can affect students' ability to learn and concentrate. Likewise, construction noise can impact patients' ability to rest and recuperate in healthcare facilities.Strong OdorsWhen using certain roofing materials on big job sites—like powerful adhesives or hot-mopped roofing systems—odors may infiltrate the building. This may be distracting and affect the comfort of students and patients.Heavy MachineryUnloading and staging material can also cause disruption, as materials must be staged onsite to be ready for installation as the job progresses. This often involves using heavy equipment, such as cranes and lifts. Proper safety protections must be in place to ensure worker and occupant safety.Roofing Products That Minimize DisruptionUnfortunately, there's no good time for a roof repair or replacement at a medical facility. You may be able to complete school projects when school is out of session, but that isn't always the case if a leak or storm damage occurs.The best (and most proactive) way to minimize disruption is to use durable, long-lasting materials, as this reduces the number of times crews need to work on the roof.Single-Ply MembranesGrant recommends a robust single-ply membrane or a system with some redundancy, such as a multi-ply modified bitumen. She also suggests leveraging a hybrid system, composed of a multi-ply modified bitumen system with a single-ply top sheet for reflectivity.Cover and Substrate BoardsFor resiliency against noise-causing conditions such as hail and foot traffic, Grant suggests using cover and substrate boards. Cover boards are installed on top of the insulation and provide sound insulation, while substrate boards are installed directly on the roof deck under the insulation."If you have a really noisy location, and you want to keep people inside from hearing a lot of disruption, having cover and substrate boards included in the system can be really important," says Grant.Adhesives and FastenersAnother change you can make to reduce disruption is using adhesive to attach roofing products instead of mechanically fastening them. This helps avoid the noise from driving fasteners into the roof deck—and enables a faster installation.Grant notes that, depending on the FM and wind ratings required, it may be possible to adhere all the system components, including the insulation, cover boards, and membrane. An adhesive like GAF EverGuard® TPO Quick-Spray Adhesive can effectively adhere TPO and PVC roofing materials. The product has a high initial tackiness, allowing for faster installation than traditional adhesives. You can also opt for self-adhering products (vapor retarder, pipe boots, TPO roofing, etc.), which can further reduce installation time by eliminating adhesive application from the process.Materials That Shorten Project TimelinesA creative and efficient way to minimize disruption at school and hospital job sites is to reduce the time crews are on the roof. By taking advantage of time-saving materials, you can reduce the risk to workers and occupants, increase productivity, and ultimately take on more work.In addition to the Quick-Spray Adhesive, GAF offers several materials designed to cut installation time and labor:Wider rolls of TPO (12 feet instead of 10 feet) can help crews to spend less time installing systems on wide-open roofs.Insulation installation is easier with lightweight Ultra HD Composite Insulation, and it eliminates the need for one full application of adhesive in adhered systems.TPO self-adhered membrane can cut installation time by as much as 60% compared to installation using traditional bucket and roller adhesives.Experienced Support That Streamlines WorkIn addition to product and material selection, you can minimize disruptions by having GAF professionals from the Tapered Design Group help design the tapered insulation system. These professionals can help you with a variety of services, such as:Tapered insulation designTapered insulation Inventory management and orderingBudget friendly alternativesTapered insulation systems are designed to improve the drainage slope on roofs with substrate damage or without enough slope. The tapered design team at GAF "balances suitable slope with the least amount of material," Grant says. "To help with saving money, saving material, and saving time."This group designs tapered insulation systems that can be loaded and labeled strategically to minimize material handling and time spent looking for and transporting materials. Products are bundled by roof area, and a color-coded plan distinguishes areas for each bundle. Materials are precut and specifically designed for each project.Additional Tools to Save Time and LaborTwo other GAF tools can help you reduce the time spent on projects: GAF QuickSite™ and GAF QuickMeasure™.GAF QuickSite™GAF QuickSite™ provides the information you need before approaching a potential customer. It gives you a snapshot of local codes (important if you're working in an unfamiliar location), a 10-year wind and hail history, historical photographs documenting changes over time, and parcel information (including size and sales dates).GAF QuickMeasure™GAF QuickMeasure™ provides complete roof measurements including parapet wall lengths, heights and widths to help create estimates, past views showing how a roof may have changed over time, grid-lined paper for buildings with predominate pitch of 0 or 1, and a DXF file output for CAD.With the help of GAF QuickSite™, GAF QuickMeasure™, and the Tapered Design Group, you can confidently give your healthcare clients and school customers accurate estimates for suitable roofing products to meet their needs. These tools can also minimize disruption to building occupants and help building owners select durable, long-lasting products that will protect their investments for years to come.Leveraging GAF Professionals' ExperienceWhen working on schools, hospitals, and other important institutions, you're working to satisfy not only your clients but the individuals visiting these locations.
