 When your roof starts showing its age, you're faced with a critical decision: should you invest in a complete shingle replacement or explore modern protective solutions like WIMAR silicone coating? This choice can significantly impact both your wallet and your home's protection for years to come. As roofing professionals, we've seen countless homeowners struggle with this decision. The experts at Best Roofing Now have helped hundreds of property owners navigate these waters, and today we're breaking down everything you need to know about both options. Understanding Your OptionsBoth shingle replacement and WIMAR silicone coating serve the same ultimate goal: protecting your home from the elements. However, they achieve this through completely different approaches and investment levels. Complete Shingle Replacement: The Fresh Start ApproachFull shingle replacement means stripping your roof down to the decking and building back up with entirely new materials. It's the most comprehensive solution available and essentially gives you a brand-new roof system.  The Major BenefitsWhen you opt for complete replacement, you're getting the maximum lifespan possible from a roofing system: typically 20 to 30+ years depending on materials chosen. You'll have full manufacturer warranties protecting your investment, and there's an opportunity to upgrade to more efficient, modern shingle technology. The process also allows contractors to address any underlying structural problems that might exist beneath your current shingles. Issues with decking, insulation, or ventilation can all be corrected during a full replacement project. From an aesthetic standpoint, nothing beats the curb appeal of a completely new roof. Your home's value increases significantly, and you won't need to worry about maintenance for many years. The Downsides to ConsiderThe biggest barrier for most homeowners is cost. Full replacement represents the maximum investment you can make in your roof, and according to industry data, roof coatings cost 50-70% less than complete replacement. The installation process is also more disruptive. You're looking at several days of extensive labor, noise, and potential weather exposure during tear-off and installation phases. WIMAR Silicone Coating: The Protective Enhancement SolutionWIMAR silicone coating takes a different approach entirely. Instead of replacing your existing roof, it creates a seamless, waterproof membrane over your current shingles, essentially giving them a protective shell. Why Silicone Coatings Work So WellIndustry experts consider silicone coatings among the most effective treatments for asphalt shingles. They form an incredibly durable barrier that's particularly excellent at handling ponding water: making them ideal for flat or low-slope applications. The UV resistance is impressive too. Quality silicone coatings can block up to 88% of harmful UV rays, which not only protects your roof but can reduce your cooling costs by 10-20%. That's real money back in your pocket every month. Best Roofing Now has seen WIMAR coatings extend roof life by 8-12 years when properly applied, which represents tremendous value for the investment required. What You Should Know About LimitationsSilicone coatings do require more surface preparation than some alternatives. Your roof needs thorough pressure washing and must be completely dry before application: no shortcuts allowed. The surface can become slippery when wet, which might be a consideration if you have foot traffic on your roof for maintenance purposes. Over time, coatings can attract dirt, which diminishes their UV protective properties. However, proper cleaning restores their performance, so this is manageable with routine maintenance. The Numbers: Cost and Performance Comparison
Making the Right Choice for Your SituationWhen Replacement Makes the Most SenseIf your roof has structural damage, compromised decking, or is simply at the end of its useful life, replacement is likely your best bet. Roofs that are leaking extensively or have extensive granule loss typically need the comprehensive solution that only replacement provides. Replacement also makes sense if you're planning to stay in your home long-term and want the peace of mind that comes with a completely new system and full warranties. When WIMAR Coating Is the Smart PlayFor roofs that are functionally sound but showing signs of aging, WIMAR silicone coating represents an excellent middle-ground solution. You get substantial protection and performance improvements at a fraction of replacement costs. This approach is particularly smart if you need immediate protection while planning for eventual replacement down the road. The 8-12 year extension you get from quality coating gives you time to budget for replacement when it makes more financial sense. The energy savings alone can help offset the coating investment over time, especially in climates with significant cooling demands. Professional Installation Makes All the DifferenceRegardless of which option you choose, proper installation is absolutely critical. Poorly applied coatings can fail prematurely, while improper replacement can lead to expensive callbacks and warranty issues. The team at Best Roofing Now has the experience and certifications to handle both types of projects professionally. Their track record speaks for itself, with hundreds of successful installations across both replacement and coating applications. Environmental Impact ConsiderationsFrom a sustainability standpoint, coating existing roofs generates significantly less waste than full replacement. If your roof structure is sound, extending its life through coating is often the more environmentally responsible choice. However, if your roof is truly at the end of its life, replacement with modern, efficient materials can provide long-term environmental benefits through improved energy performance. The Bottom LineBoth shingle replacement and WIMAR silicone coating have their place in modern roofing solutions.
The right choice depends on your roof's current condition, your budget, and your long-term plans for the property. For most homeowners with aging but structurally sound roofs, WIMAR coating offers an excellent value proposition. You get substantial protection improvements, energy savings, and years of additional life at 30-50% of replacement costs. If your roof has significant structural issues or you want the maximum lifespan possible, replacement remains the gold standard.  The Reality of Roof Moss in the Pacific NorthwestPortland’s rainy, tree-filled environment makes roof moss an ongoing battle for many homeowners. Left untreated, moss can damage shingles, trap moisture, and shorten the lifespan of your roof. Naturally, many homeowners ask: How much does it cost to remove moss in Portland? Let’s break it down. Average Moss Removal Costs in PortlandWhile costs can vary, most homeowners in the Portland area can expect to pay between $275 and $400 for professional roof moss removal. Smaller or newer homes may fall below this range, while larger or heavily affected roofs could exceed it. What Affects the Cost of Moss Removal?✅ Roof Size & Complexity : Larger roofs require more time, labor, and cleaning solutions. Homes with steep slopes or multiple stories also increase the job's difficulty, and that adds to the cost. ✅ Moss Severity A roof with light moss coverage will take less time and material than one that’s been neglected for years.
