Most residential roof replacements in San Mateo take between 2-5 days to complete, depending on the size of your home, roof complexity, and weather conditions. A typical single-family home can often be completed in 2-3 days. Our efficient process includes tear-off, inspection of the roof deck, any necessary repairs, and installation of your new roofing system. We assign a dedicated project manager to every job who will provide you with a detailed timeline during your free consultation. At Elm Roofing, we work diligently to minimize disruption to your daily life while never compromising on quality or safety.

Elm Roofing stands behind our work with a comprehensive 10-year warranty on all roof installation and replacement projects. Our warranty covers workmanship defects including issues with installation, material application, and structural integrity related to our work. This is in addition to manufacturer warranties on roofing materials, which vary by product and can range from 20-50 years. Our warranty ensures that if any problems arise due to installation errors, we’ll make it right at no cost to you. This demonstrates our confidence in our skilled craftsmanship and our commitment to your long-term satisfaction and peace of mind.

Several factors help determine whether you need repairs or a full replacement. Consider a full roof replacement if your roof is 20-25+ years old (for asphalt shingles) or nearing the end of its expected lifespan for other materials. Other signs include widespread shingle damage affecting more than 30% of the roof, multiple leaks in different areas, sagging roof deck, significant granule loss, daylight visible through the roof boards, or consistently high energy bills due to poor insulation. If you’ve had multiple repairs in recent years or damage is extensive, replacement is often more cost-effective than continual patching. Our free professional roof inspection will provide an honest assessment of your roof’s condition and our recommendation on the best course of action for your specific situation.

For Bay Area weather, we recommend materials that handle our unique climate of wet winters, dry summers, and moderate temperatures. Composite/asphalt shingles are excellent all-around performers, offering durability and affordability with good resistance to our weather conditions. Tile roofs (clay or concrete) are ideal for our Mediterranean-like climate, providing superior longevity, fire resistance, and energy efficiency by reflecting heat. TPO and EPDM roofs work exceptionally well for flat or low-slope roofs, offering UV resistance and waterproofing. For homes in foggy coastal areas, we often recommend materials with enhanced moisture resistance. During your consultation, we’ll assess your home’s specific location, architecture, and exposure to recommend the optimal material that balances performance, aesthetics, and budget for your property.

Homeowners insurance typically covers roof replacement if the damage resulted from a covered peril such as storm damage, fallen trees, fire, or vandalism. However, insurance generally won’t cover replacement due to normal wear and tear, age, or lack of maintenance. The key is proving that damage was sudden and accidental. At Elm Roofing, we have extensive experience working with insurance companies and can help document damage for your claim. We’ll provide detailed reports, photographs, and estimates that support your insurance claim. We recommend contacting your insurance company promptly after discovering damage and scheduling a professional inspection. Our team can meet with your insurance adjuster to ensure all damage is properly identified and documented.

Yes, we can replace your roof during the rainy season with proper planning and protective measures. At Elm Roofing, we monitor weather forecasts closely and strategically schedule work during dry windows. We use heavy-duty tarps and weatherproofing techniques to protect your home if unexpected rain occurs during the project. Our experienced crews work efficiently to minimize the time your roof is exposed, often completing critical waterproofing stages in a single day. For urgent replacements during winter months, we prioritize protecting your home’s interior and can section the work to ensure continuous coverage. While ideal conditions are always preferred, we understand that roof emergencies don’t wait for perfect weather, and we’re equipped to handle replacements safely and effectively year-round.

Reroofing (also called overlay) involves installing a new layer of shingles over your existing roof, while roof replacement means completely removing the old roof down to the deck before installing new materials. Reroofing is faster and less expensive since it eliminates tear-off and disposal costs, but it’s only suitable for roofs in relatively good condition with a single existing layer. Reroofing can mask underlying problems and typically voids some manufacturer warranties. Full roof replacement allows us to inspect and repair the roof deck, replace damaged underlayment, ensure proper ventilation, and address any structural issues. While more expensive upfront, replacement typically provides better long-term value, longer lifespan, and maintains full warranty coverage. During your free inspection, we’ll assess which option is appropriate for your roof’s condition and provide honest recommendations.

At Elm Roofing, protecting your property is a top priority throughout the roof replacement process. We place protective tarps over landscaping, gardens, and outdoor furniture near the work area. Our crews use magnetic sweepers and thorough ground cleanup daily to collect nails and debris. We install protective boarding on walkways where needed and set up containment systems to catch falling materials. Inside your home, vibrations from roof work can occur, so we recommend removing wall hangings and securing fragile items. We also protect your driveway and vehicles by designating equipment zones away from parked cars. Our dedicated project manager conducts daily inspections to ensure protection measures remain in place. At project completion, we perform a comprehensive cleanup including a final magnetic sweep, ensuring your property is left in pristine condition.
