5 señales de mala ventilación en una casa

¿Conoces las señales de advertencia de mala ventilación en una casa y ático? La ventilación adecuada es importante por muchos motivos, y uno de los principales conceptos a tener en cuenta es que puede prolongar la vida útil de tu sistema de techo. También puede ayudar a reducir la temperatura del ático y, por lo tanto, el desgaste del HVAC, lo cual, a su vez, puede reducir las facturas de servicios públicos y la probabilidad de reparaciones costosas. Y por último, pero no por eso menos importante, la ventilación del ático puede ayudar a reducir el riesgo de moho, lo que protege la salud de su familia. All-in-all, attic ventilation offers a long-term return on investment as well as potential preventative health benefits.What Happens to a Home That's Poorly Ventilated?Poor attic ventilation negatively impacts your home and can ultimately cost you money. But what makes for a good ventilation system? Ideally, a well-balanced roof ventilation system will efficiently draw cool exterior air into the attic through intake vents and push hot interior air out through exhaust vents. This helps maintain your attic's temperature so that it's similar to the ambient outdoor temperature. When an attic doesn't have proper ventilation, or the ventilation system is blocked by paint, debris, or insulation, hot air gets trapped in your attic's highest points.Trapped hot air leads to trouble all year round, including roof ice dams in winter and overworked HVAC systems in summer. Proper ventilation helps prevent home repairs and protects your roof investment. That's why it's so important to recognize the warning signs.How Do You Know If You Have Poor Attic Ventilation?1. Excessive Heat in the AtticA hot attic may feel cozy, but it's one of the warning signs of poor ventilation in a house. Perhaps counterintuitively, your ideal winter attic temperature is similar to ambient outdoor temperatures. With poor ventilation in house, the hot air concentrated at your attic's highest points stays trapped. This, in turn, can lead to uneven roof temperatures (ice dams), an overtaxed HVAC (higher energy bills), and other costly headaches.An indoor digital wall thermometer is a good way to help determine if your attic temperatures are too high.2. Visible Moisture on PlywoodWet wood in your attic is not a good sign. When warm, moist air from your home is trapped against your attic ceiling, condensation can occur. Any sign of visible moisture on plywood is a red flag.Look for beaded water, condensation on hard surfaces, water stains, rusted nails, or rust stains around nail heads. It's important to address visible moisture quickly because trapped, warm, and wet air is a breeding ground for mold and mildew.3. Mold or MildewIf left untreated, mold and mildew can negatively impact you and your family's respiratory health, and deteriorate plywood, drywall, and other building materials.Discolored patches, including white, orange, pink, green-black, gray, or black colors, can be indicators of mold. An active leak or damp area is a possible indicator that mold or mildew is also present. A musty or unpleasant damp smell is another sign. If you're concerned about mold or mildew in your attic, contact a professional.4. Cracked or Curling ShinglesPoor ventilation can damage shingles by causing extreme roof temperatures, water damage to roof decking, and more. That's why it's important to be alert to the state of your roof's exterior. A regular roof inspection (performed safely from the ground with binoculars) can help you keep tabs on the situation. Warning signs of shingle damage caused by poor ventilation can include blistering on the shingles, granule loss, and curled, cracked, or brittle shingles. If you notice these warning signs, contact a certified roofing contractor.5. Ice DamsIcicles around your roof's perimeter may look magical, but don't be deceived. They can be a sign of ice dams caused by poor attic ventilation.The excess warm air that results from poor ventilation gets trapped within the steeper parts of your roof. This can then melt the snow on the roof exterior above it. The melted snow then drips down and refreezes on lower, cooler areas. This freeze-thaw cycle can create built-up ice dams around the base of your roof that just get larger over time.When ice dams are not removed, the built-up ice and water can infiltrate your roofing system, leading to shingle damage, roof leaks, and even structural home damage.What Are the Health Problems Caused by Poor Ventilation?As mentioned, property damage isn't the only negative consequence of improper attic ventilation. Changes in your family's health can also, unfortunately, be a warning sign. In fact, mold in the home can cause "sore throats, stuffy noses, coughing or wheezing, burning eyes, or skin rash," according to the Centers for Disease Control and Prevention. Asthma and allergies can be triggered by mold and immunocompromised folks are at a higher risk for lung infection.The right attic ventilation can hopefully save you money on home repairs and medical care, while helping maintain the health of your family and home.

    How to Detect and Address a Roof Leak: A Homeowner's Guide

    If you think your home might have a leak in the roof, you're right to be concerned. A leak, if left unrepaired, can lead to many problems, from mold to water damage. Detecting the issue early-and figuring out what's causing it-can help limit the damage.So, here's how to tell whether you have a roof leak, the common causes, and what to do next.How to Detect a Roof LeakHere are a few signs you might have a leaking roof.StainingWater stains, which look like brownish or yellowish spots, on your walls, floors, or ceilings are signs you have a leak. A plumbing leak can also cause these stains, but finding them in the attic or near other roofing structures means water is likely coming from the roof.MoldMold grows in humid environments, and roof leaks can create the perfect conditions for this growth. If you see mold around the attic and insulation, you may have a leak or your attic may not have proper ventilation. Either way, it's an issue you'll want to address.SaggingSagging ceilings can indicate leaks and issues with your roof's structural integrity. If water has accumulated in the roof decking, the wooden materials can rot and become damaged, weakening them. As water collects, it can also cause these materials to grow heavier, leading to sagging ceilings. This is a safety hazard you'll want to fix as soon as possible.Common Causes of Roof LeaksYour roofing system might develop a leak for several reasons.Severe WeatherWeather-related damage is one of the major sources of roof leaks. Exposure to moisture from rainstorms can cause materials like shingles or flashing to deteriorate and eventually allow water to seep into the structure below. Sharp winds can lift or warp shingles, letting water enter the damaged area. Hail can crack shingles and flashing. Even temperature fluctuations can cause materials to become brittle and crack as they expand and contract with these changes.Faulty Roof WorkImproperly installing roofing materials can also lead to roof leaks. When shingles aren't aligned or securely attached to the roof, it creates small openings where water can pool. This can occur when nails aren't driven in all the way or not enough nails are used. That's why certain shingles like GAF Timberline HDZ® use patented LayerLock® Technology that helps your roofer achieve a 99.9% nailing accuracy. Since flashing protects the vulnerable parts of the roof, improper flashing installation can also cause problems.Additionally, many homeowners try to save money by making repairs themselves or hiring low-quality contractors who don't do the job correctly or use cheap materials. This can lead to further and more expensive repairs down the road.Simple Wear and TearWear and tear over time can also cause roof leaks. Roofing materials can deteriorate over the years due to harsh weather, ultraviolet rays, and roof movements.Animals and Tree BranchesLess common causes, which still pop up now and then, include damage from animals and tree branches. The heavy impact from tree branches can crack shingles, leaving room for openings. Small critters like rats and squirrels can chew through roofing material or burrow into it, creating openings for water to enter.Call A Professional to Repair LeaksIt isn't always easy to identify the main source of a leak yourself. So, as soon as you notice any signs of a leak, call a trusted roofing contractor. They can find the leak's source, install quality materials to fix it before further damage occurs, and prevent it from happening again. A contractor can also help determine whether you need a new roof entirely.How to Prevent Roof Leaks in the FutureWith regular maintenance, you can catch leaks before they occur and extend your roof's life.Schedule A Professional InspectionIt's recommended to get your roof professionally inspected at least twice a year. When a leak is in the first stages, you might not notice signs immediately. A contractor can detect these issues before they happen and repair any damaged areas, such as shingles or flashing. These proactive steps are often less expensive than, for example, replacing damaged insulation from water damage or replacing the roof decking due to rot.Inspect Your Attic and RoofIn addition to professional inspections, monitor your attic and roof to determine whether you need a roof repair. From your attic, look for any sunlight that might be entering. If light can get into your attic, that means water can too. If you have a leak, you might see small dark spots or smell mildew or mold.While you should avoid climbing on your roof (leave this to the professionals who have the proper safety equipment and training), you can inspect your roof from the ground. Look for missing or damaged shingles, holes, and damage to the gutters and flashing.Clean Your GuttersMake gutter cleaning part of your yearly maintenance, or hire someone to do it. When your gutters become clogged with debris, water has nowhere to go and will remain on the roof or make its way inside. Installing gutter guards can help reduce the need for gutter cleanup.Trim Tree BranchesTrimming the tree branches near your roof can further prevent leaves from clogging the gutters. This step can also prevent branches from scratching your shingles on windy days or falling on your roof, leading to cracks.Catch Leaks Early to Minimize DamageYour roof is one of your home's most important structures. So, as soon as you notice signs of a leak, contact a roofing contractor, and prevent future leaks with regular roof maintenance and inspections. By taking these steps, you can ensure your roof protects what matters most for years to come.Ready to hire a contractor to fix a leak or inspect your roof?

    How to Put Up Holiday Lights and Seasonal Decor Without Risk

    While it can be fun to put up holiday lights, it's traditionally had its share of downsides. In addition to requiring a ladder, adding seasonal cheer to a home's exterior previously involved driving screws, nails, or staples into the roof or siding. The small holes these fasteners create can allow moisture to penetrate the roofing system, potentially leading to leaks, mold, and mildew.These days, you can choose many options to spread holiday cheer without damaging your home or taking on unnecessary risks. Here are the most effective ways to decorate for the season.Consider Decor That Doesn't Involve the RoofThe safest way to bedeck your home for the holidays is to decorate another part of the house or your yard, away from the roof. Here are a few ideas.ProjectorsLight projectors shower your home with a moving light display, featuring anything from snowflakes to traditional holiday characters. With many options, you're sure to find one that suits your house and neighborhood. And since the projector units sit close to the ground, you don't risk damage to your home and don't need a ladder to install them.InflatablesInflatables are staked into the ground and can help create a variety of holiday themes, from the classic nativity scene to an eye-catching menorah. They're easy to install and won't damage your home. However, inflatables are susceptible to weather events-during high winds or heavy snowfall, you may want to unplug or turn off the fan to prevent them from taking flight or creating a risk of electric shock.Tree LightsYou can hang lights from trees, landscaping, or other structures in your yard. Stringing lights around bushes, up light poles or tree trunks, and under a carport are all good alternatives to hanging them on the roof.How to String Holiday Lights on Your HouseIf you really want to put up holiday lights on your house, you can do so safely without damaging your roof or siding.Seek HelpOnly use a ladder with a partner nearby to help maintain stability and provide assistance. If you don't feel comfortable climbing a ladder or want additional help, contact a roofing contractor.Use Plastic ClipsYou can mount holiday lights using plastic clips that attach to gutters or shingles. The most common ones clip to the gutter's edge and hold either individual lights or the wire between them. You can also use siding clips to string lights vertically.Alternatively, you can install roof peak clips, which grip the shingle's edges at the top of the roof. They require access to the roof ridge, so professionals often use them.To remove the lights at the end of the season, take down the clips individually. Don't pull on the string of lights, as doing so could damage your gutters or the light string.Try Magnetic ClipsYou can use magnetic clips to attach individual bulbs or sockets to metal roofs or flashing. You can easily take them down by pulling on the string of lights (in this case, it's OK).While you're working around your roof, take a few minutes to inspect it for potential damage or quality issues. Contact a contractor if you have any concerns.Holiday Lighting OptionsSelect lights that are properly rated for outdoor use. LEDs are often recommended due to their energy efficiency, and they don't heat up like incandescent bulbs. You can also plug in multiple strings to the same outlet without fear of overloading the circuit, making LED lights more versatile.When it comes to types of holiday lighting, you have a few options.Large BulbsIt doesn't get much more traditional than large bulbs. You can use clips to ensure they're all pointing the same way, or string the cord through them for a more carefree look.Mini LightsMini lights don't put out as much light as large bulbs, so they may not be the best option for the roof. However, they're great for windows, trees, or indoor displays.Icicle LightsIcicle lights have strings of small bulbs that hang down from the gutter or roof to look like icicles. Use clips to attach the main string to the gutter line.Raindrop LightsRaindrop lights are animated to look like raindrops. You can hang them in a cluster in a small area or spots where traditional string lights don't work.Decorative Bulb CoversDecorative bulb covers give your home a unique look. You can get them shaped like snowmen, stars, ornaments, or other holiday motifs.Smart LightsSmart lights are the newest trend in holiday lighting. An app lets you control the lighting colors, patterns, intensity, and blinking speed so you can create your own unique light show. When paired with music, your home will become a neighborhood attraction.Remember to Prioritize SafetySafety should always be your first priority when you put up holiday lights. If you need a ladder to achieve your desired design, don't climb one without a helper nearby, and ensure you have the right ladder for the job. Also, attaching lights to your house with temporary clips instead of permanent fasteners can help keep your roofing system healthy.If you notice any roof damage or concerns while planning your holiday decorations, don't hesitate to contact a roofing contractor that's certified by GAF. They have the expertise to assess and address any roofing issues, ensuring your home stays protected throughout the holiday season and beyond.Whether you hang lights or opt for other outdoor decor, you can spread holiday cheer this season safely and creatively.

    What to Look for When Finding a Contractor

    Your roof is a long-term investment that helps protect your family, may improve your home's resale value, and crowns your home's aesthetic so finding a contractor that is qualified is very important. To help you choose a roofing contractor with confidence, here are three qualities to look for.1. Professional Experience and ReputationBefore you hire, do your research. Choose a company based on experience and reputation-not just price. If you decide on price alone, you may not be making the best choice.RecommendationsWord-of-mouth from trusted sources is a great starting place. Ask neighbors, friends, and online community forums for referrals.ResearchVisit the company's website to determine the products and services it offers-as well as the number of years it's been in business. Then, verify the company is licensed and insured.ReviewsNext, read reviews from multiple online platforms to learn about customer experiences. Resources could include Google Reviews, Yelp, Better Business Bureau, and the company's social media pages. While searching, look for info such as ease of interactions, professionalism during installation, cleanup after project completion, and overall satisfaction with the outcome.2. CertificationsFinding a contractor certified by a manufacturer typically indicates that a contractor has met the certification requirements of the manufacturer. For example, contractors certified by GAF must be insured and licensed in states where they operate (if required). GAF also considers factors such as years of roofing experience, credit rating and overall standing with the Better Business Bureau.Higher tiers of certification may be allowed to offer better enhanced warranties on qualifying roofing systems. For example GAF Master Elite® Contractors are entrusted to offer the GAF Golden Pledge Limited Warranty* on qualifying roofing systems, which provides up to 30 years of misapplication coverage.VerificationVerify contractor certifications whenever possible. For example, the GAF website lets you verify whether a company is certified by GAF by simply entering their phone number or contractor ID.AwardsIn addition to certifications, select contractors may also qualify for manufacturer awards. For example, the highest distinction a GAF Master Elite® contractor can earn is the GAF's President's Club Award. This award indicates that a contractor has demonstrated commitment to installing GAF roofing systems backed by GAF's strongest warranties and dedication to learning about GAF's products and services.3. Operational ApproachAfter identifying several contractors, consider these talking points when interviewing the contractors:ExperienceAsk the contractor whether it has experience installing roofs on the type of roof architecture you have.AvailabilityWhen do you need the project to start, and when can the company actually do the installation? If your roofing needs are urgent (leaks, damage, etc.), make sure they can perform the work in the timeframe you are looking for.EstimateAsk the contractor to provide you with an estimate. As a preliminary step, try using GAF's estimate tool. However, keep in mind that the estimate provided by the tool is non-binding and contractors will provide their own estimates. Review actual estimates from contractors closely to understand what is included. The cheapest option is not always the best. Consider experience, and reputation, too.Payment OptionsAsk your contractor about payment options, including payment and financing options to make sure you choose the best option for you.Starting Your SearchPrioritizing these qualities when looking for a contractor may help you find the right company for the job.Are you ready for a new roof?

    Cómo hacer una inspección del techo desde el suelo

    As a homeowner, it's always a good idea to stay on top of routine maintenance that will help protect your biggest investment-and that includes a regular roof inspection. Catching leaks or damage early can help preserve your roof's longevity and prevent major issues.But getting up on a ladder to walk around on your roof can be dangerous. It's safer to visually inspect your roof from the ground. Read on to learn how to conduct a routine roof check, so you'll know when it's time to bring in a professional.Walk around the Entire PropertyTo see all the angles of your roof, you'll first need to walk around your home, looking up and down. Check for any fallen shingles or debris on the ground or any missing spots on the roof where shingles may have broken off.Using binoculars, look for moss, piles of leaves, algae, or other debris on the roof. If left unaddressed, this debris can damage the structure by trapping moisture, eventually causing it to seep into the sheathing beneath your shingles. After some time, this can develop into serious water damage and leaks.Look for Damaged ShinglesExcessive heat and moisture in your attic, typically caused by inadequate ventilation, may compromise the roof system's performance or even cause shingles to become misshapen or damaged. Loose, curled, cracked, or buckled shingles can leave room for water to seep in and damage your roof's underlayment.If you see shingles that don't look right or are missing altogether, consult a roofing professional. They can help you understand if it's a simple fix or indicative of something larger, meaning it could be time to replace the roof.Check Your Gutters, Fascia, and SoffitNext, look for obvious damage, such as holes, dents, mold, or cracks. Gutters clogged with branches, leaves, or dirt can prevent water from draining off the roof. Also, asphalt shingles contain small, gravel-like granules, and if you see this material has ended up in your gutters, it can mean the shingles are nearing the end of their lifespan. Inspect the downspout to be sure it's clear of debris, too.While you can remove leaves or sticks yourself, hire a gutter cleaning service for a larger blockage. If you need to climb a ladder to reach any part of your gutters, it's best to leave that to an insured service.Peek at the Flashings from the BalconyIf you have a balcony or other way to safely view your roof from above, get a closer look at the flashings. These are the metal components that redirect water from your roof, located around your chimney, vent pipes, and dormers.Flashings are often the most vulnerable areas around your roof and the first to show wear and tear. If they're dented, rusty, or otherwise damaged-or if the caulk is brittle or cracked-water can get into your roof's interior structure and lead to rot.Examine the Attic or CrawlspaceAfter your exterior inspection, head inside. Some hidden roof damage or water infiltration can be seen from your attic. Using a flashlight, look for signs of rotting wood joists, sunlight coming through the joints, water damage on the floor, or any vulnerable spots around vents, skylights, or the chimney. Also check your rafters, insulation, and any other wooden structures for signs of mold, moisture, and rot.Scan Your Home's InteriorSome early signs your roof might be leaking are obvious from inside the house. Look for damp spots near the fireplace, water stains on the pipes that vent your furnace or water heater, dark patches, or peeling paint on your ceilings.When to Go with a ProPerform a visual roof inspection twice a year-in the spring or early summer and again in the fall. Conducting regular inspections helps you get to know your roof and spot any issues immediately.If your roof looks like it's in good shape after your inspection, you probably don't need to call in a licensed roofing contractor. However, if you've seen any worrisome signs of damage or leaks, it's best to book a professional inspection before the issues worsen. A GAF-certified roofing contractor* can make any necessary repairs, so your roof continues to protect your most valuable asset.*Contractors enrolled in GAF certification programs are not employees or agents of GAF, and GAF does not control or otherwise supervise these independent businesses.
