The harsh weather in Buffalo can have a profound effect on homeowners with asphalt shingle roofs, leading to premature deterioration if it’s not properly maintained. One of the best ways to prevent this from happening is to seal asphalt shingles against the weather extremes.
Waterproofing asphalt roof shingles properly creates a protective barrier that prevents moisture from entering, which is especially important during Buffalo’s wet seasons. When water seeps beneath unsealed shingles, it can cause warping, cracking, and eventually leak into your home. These issues often start small but quickly escalate into major structural problems requiring extensive repairs.
Beyond weather protection, applying asphalt shingle roof sealant offers multiple benefits. It significantly extends the lifespan of your roofing materials, sometimes adding 5 to 10 years to their functional life. A sealant also enhances your home’s curb appeal by maintaining the rich color of your shingles and preventing the growth of unsightly algae and moss.
Most importantly, implementing regular asphalt shingle maintenance techniques like sealing is a smart financial decision. The minimal investment in preventive care helps Buffalo homeowners avoid the substantially higher costs associated with major roof repairs or premature replacement. With proper sealing, your asphalt roof remains resilient against Buffalo’s challenging climate year after year.
Understanding Asphalt Shingle Vulnerabilities in Western New York
Asphalt shingles in Buffalo and the surrounding areas face a perfect storm of challenging conditions that make protective sealing particularly important. Roofing materials in Western New York’s climate face extreme temperature fluctuations, with summer heat reaching into the 90s and winter temperatures plummeting well below freezing. These dramatic swings cause roofing materials to continually expand and contract, weakening their form and durability over time.
Buffalo’s heavy lake-effect snow, averaging over 95 inches annually, creates additional stress through the weight burden and moisture exposure. When this snow melts and refreezes, it forms ice dams that force water beneath unsealed shingles. Meanwhile, the region’s strong winds, occasionally exceeding 50 mph, test shingle adhesion and lift edges that aren’t properly sealed.
Warning signs that your asphalt shingles need sealing include granule loss in gutters, curling or buckling edges, and minor water stains on interior ceilings. If you notice black streaks developing on your roof, this indicates algae growth that proper sealing can prevent. Shingles that appear dry, brittle, or have lost their protective coating are especially vulnerable to moisture penetration.
Selecting the Right Sealant for Your Asphalt Shingle Roof
Choosing the appropriate sealant for your asphalt shingle roof is critical, especially given Buffalo’s challenging weather patterns. Three main types dominate the market, each with distinct characteristics. Silicone-based sealants offer superior waterproofing and UV resistance, making them particularly effective against Buffalo’s intense summer sun and heavy precipitation. Though more expensive, their longevity often justifies the investment for Western New York homes.
Acrylic sealants provide excellent flexibility and adhesion at a more moderate price point. They perform well in Buffalo’s freeze-thaw cycles but may require more frequent reapplication than silicone alternatives. For budget-conscious homeowners, asphalt-based sealants deliver good initial protection and compatibility with existing shingles, though they typically offer shorter protection periods in our harsh climate.
When evaluating the quality of sealant, several factors deserve attention. The first is to assess how capable the sealant is at providing waterproof coverage. Premium sealants create a truly impenetrable barrier against moisture. You should also consider flexibility as sealants must expand and contract with temperature fluctuations without cracking. UV resistance prevents degradation from solar exposure, while temperature tolerance ensures performance during both summer heat and winter freezes.
For Buffalo roofs, we recommend silicone or high-grade acrylic sealants with elastomeric properties. These products maintain their protective qualities through extreme weather conditions and typically offer 5 to 7 years of reliable protection before reapplication becomes necessary.
A Step-by-Step Guide to Properly Seal Asphalt Shingles
Properly sealing asphalt shingles begins with preparing the surface thoroughly. This starts by removing all debris, leaves, and branches using a leaf blower or soft-bristle broom. For Buffalo homes, pay special attention to cleaning moss and algae that frequently develop in our humid conditions. A solution of water and mild detergent works well for basic cleaning, while stubborn biological growth may require a specialized roof cleaner containing zinc or copper compounds.
Before application, inspect your entire roof for damaged or loose shingles. Replace any compromised materials and secure loose fasteners. Timing is critical here, as the ideal conditions include temperatures between 50 and 85 degrees Fahrenheit, with low humidity and no precipitation forecast for at least 24 hours. Buffalo’s weather can be unpredictable, so monitoring the forecast carefully helps ensure a successful application.
When applying asphalt shingle roof sealant, work in small sections using even, overlapping strokes. Start at the roof’s highest point and work downward, allowing gravity to assist with proper coverage. Apply a thin, consistent coat rather than a heavy application, which can lead to pooling or uneven drying. Pay special attention to vulnerable areas like edges, valleys, and around chimneys or vents where water intrusion commonly occurs.
Common mistakes to avoid include applying sealant during inappropriate weather conditions, using expired products, or improperly mixing two-component sealants. For optimal results, allow for a specified curing time, typically 24 to 48 hours, before the roof is exposed to rain or heavy dew. Following these waterproofing techniques ensures your Buffalo home remains protected through all seasons.
Professional vs. DIY Shingle Sealing: Making the Right Choice
When it comes to sealing asphalt shingles in Buffalo, homeowners face an important decision: tackle the project themselves or hire professionals. DIY sealing can be appropriate for newer roofs with minimal issues on single-story homes. If you’re comfortable working at heights, have the proper safety equipment, and your roof has a gentle slope, a DIY approach might save you money. However, be realistic about your abilities, as roofing work requires proper techniques to be effective.
Professional sealing becomes necessary for homes with steep pitches, multiple stories, or when shingles show signs of significant wear. Buffalo’s extreme weather conditions demand precise application that experienced contractors can provide. Professionals also understand how different sealants perform in our specific climate and can identify underlying issues that might compromise your roof’s integrity. Importantly, DIY applications may void manufacturer warranties, while professional work often comes with service guarantees.
When hiring a Buffalo roofing contractor, expect a thorough inspection, a detailed estimate, and a clear timeline. Professional sealing typically takes 1 to 2 days, depending on roof size and complexity. Ask potential contractors about their product selection, application methods, and whether they offer maintenance programs. Request references from previous Buffalo clients whose homes have endured several seasons after sealing.
Maintaining Your Sealed Asphalt Shingle Roof Throughout The Seasons In Buffalo
Buffalo’s distinct seasonal changes demand a tailored approach to maintaining your sealed asphalt shingles. During winter, safe snow removal becomes critical to prevent excessive weight on its surface. Use a roof rake with a plastic edge from ground level, leaving 1 to 2 inches of snow to avoid damaging the sealant. Never chip ice directly off shingles, as this can break the waterproof barrier that protects your home.
Spring calls for a thorough inspection after winter’s harsh conditions. Check for sealant cracks, particularly around flashing and valleys where melting snow builds up. Summer brings intense UV exposure that can degrade protective coatings, so inspect for signs of blistering or granule loss that might indicate sealant deterioration. Fall maintenance should focus on clearing debris from gutters and roofing surfaces before winter returns.
To maximize sealant effectiveness, schedule professional inspections every two years. Most asphalt shingle sealants in Western New York require reapplication every 5 to 7 years, though high-quality applications may last longer. Between treatments, address any damage as soon as possible, as even small compromises in your roof’s sealed surface can lead to significant problems during Buffalo’s intense weather events.
Track your roof’s performance through seasonal changes, noting any new leaks or interior signs of moisture. Consistent monitoring and preventative care will ensure your waterproofing investment continues protecting your home through Buffalo’s challenging climate cycle, extending the life of your asphalt shingles significantly.
Environmental and Energy Benefits of Properly Sealed Asphalt Shingles
Properly sealed asphalt shingles deliver significant energy efficiency benefits to Buffalo homeowners dealing with extreme seasonal temperature variations. During harsh winter months, a well-sealed roof creates an additional barrier against heat loss, potentially reducing heating costs by 10% to 15%. The sealant fills microscopic gaps between and beneath shingles that would otherwise allow warm air to escape and cold drafts to enter your home’s thermal envelope.
In summer months, sealed shingles reflect more solar radiation and help maintain cooler attic temperatures. This reflective quality reduces the burden on cooling systems and can lower summer energy bills. Many homeowners report more consistent indoor temperatures throughout their homes after professional asphalt shingle roof sealant application, eliminating previously problematic hot or cold spots.
From an environmental perspective, extending your roof’s lifespan through proper sealing represents a significant win for sustainability. Each year of additional service from your existing roof prevents approximately 2 to 3 tons of asphalt shingle waste from entering landfills. Since asphalt shingles can take up to 300 years to decompose, waterproofing techniques that extend roof life directly reduce your home’s environmental footprint.
The production of new roofing materials is also resource-intensive, requiring petroleum products, mining of mineral granules, and substantial energy for manufacturing and transportation. By implementing regular maintenance and sealing of asphalt shingles, Buffalo homeowners make an environmentally responsible choice while simultaneously protecting their homes and reducing long-term energy expenses.
