Frequently Asked Questions
We provide a standard 5-year workmanship guarantee on all new installations, regardless of whether it is steep-slope or low-slope, or the type of material selected.
Yes! If you upgrade to our CertainTeed SureStart™ coverage, the warranty is fully transferable to the next property owner at no additional cost during the SureStart period.
NDL stands for "No Dollar Limit". Available through our GAF Diamond Pledge™ Guarantee for commercial roofs, this means the warranty covers the full cost of repairs to fix covered leaks, regardless of the original cost of the roof.
Generally, roofing warranties do not cover "Acts of God," such as severe hail or wind storms. Our enhanced manufacturer warranties protect against defects by covering both labor and material for 25 years. Severe weather damage is typically handled through your homeowner's or commercial property insurance policy rather than the roof's warranty.
A roofing warranty can be voided by a lack of routine maintenance, improper roof ventilation, or making unapproved structural alterations, such as adding solar panels without consulting a professional. We always recommend reaching out to our team for guidance before making any major modifications to ensure your warranty remains fully intact.
While many basic manufacturer warranties do not cover the labor required to remove and dispose of bad shingles, our elite extended options offer superior protection. Through our elite certifications, we can offer extended manufacturer warranties that cover both labor and material for 25 years.

We provide emergency services during business hours.
Our free diagnostic inspection will give you a definitive answer. We operate with uncompromising integrity and will never upsell a total replacement when an honest repair will do. Generally, warning signs that you need a replacement include a roof over 20 years old, significant granule loss, curling shingles, or daylight visible in the attic.
We are certified in all major material applications for both steep-slope and low-slope roofs.
For residential (steep slope): We install composition asphalt shingles, standing seam metal, clay and concrete tile, wood shake, slate, and synthetic roofing.

Sectional gutters are pieced together, creating dozens of seams around your roofline. Over time, these seams expand, contract, and inevitably leak. Seamless gutters are custom-fabricated on-site to fit your exact dimensions, providing superior leak prevention and structural integrity.
Yes, we offer comprehensive cleaning and maintenance services. Keeping your gutters clear of debris and ensuring your roof's drainage pathways are unobstructed is the easiest way to prevent unexpected leaks and foundation erosion.
Absolutely. We believe a gutter system is only as good as its exit point. Our "Water Management" philosophy ensures that water isn't just caught, but is safely diverted completely away from your home. By ensuring the proper system pitch and utilizing strategic downspout extensions, we actively prevent heavy storm runoff from causing severe soil erosion or basement flooding.
Yes, Central Roofing provides complete diagnostics and custom estimates absolutely free of charge, regardless of the project size. Our experts will conduct a physical walk-through of your property to assess your unique drainage or airflow needs, providing you with a detailed, itemized breakdown of the necessary materials and labor.
Yes. Before recommending a total structural replacement, our experts conduct thorough diagnostics. If your underlying insulation is sound, we frequently utilize liquid-applied coatings that can be rolled or sprayed directly over existing substrates. This extends the life of your current roof and offers system warranties for up to 20 years, maximizing your immediate ROI.
Absolutely. If your project requires strict adherence to government mandates, our Public Works & Municipal team is highly experienced in the specific requirements of the public sector, including detailed submittals, industry standards, prevailing wage practices, and regulatory compliance.
Headquartered in South San Francisco, we proudly serve commercial facilities and government agencies throughout San Francisco & San Mateo County.

Yes, we install heavy-duty, energy-efficient "Cool Roof" solutions, such as high-performance white Single-Ply TPO and PVC membranes. By reflecting intense UV rays away from the building, these materials significantly lower interior cooling costs and frequently meet the stringent LEED certification requirements mandated for many new government and educational facilities.
Safety and minimal disruption are top priorities when working on occupied public property. We implement a strategic "Minimal Disruption Plan," which includes careful material staging and the flexibility to coordinate off-hours work if necessary to keep your facility fully operational. Furthermore, our crews adhere to the strictest OSHA safety standards to ensure the complete protection of the public, your staff, and our workers during the entire installation process.
Headquartered in South San Francisco, our team is equipped to manage large-scale public works projects across the entire Bay Area. Our local service footprint includes San Francisco & San Mateo County.

Often, yes. If our core sampling determines your underlying insulation is dry and structurally sound, we can preserve your roof using liquid-applied coatings or install a new single-ply membrane directly over the existing substrate.
Yes, we provide commercial roofing systems and asset management throughout San Francisco & San Mateo counties.
Commercial property owners should view a roof as a financial asset. We highly recommend white TPO single-ply membranes because of their exceptional Solar Reflectance Index (SRI). These "Cool Roof" systems reflect intense UV rays away from your building, which significantly lowers your interior cooling costs, reduces the daily strain on your HVAC equipment, and provides a measurable return on investment.
We understand that your facility needs to stay open. That is why we implement a "Minimal Disruption Plan" for all commercial roofing projects. We carefully stage our materials and can coordinate work-hour flexibility—including off-hours work if necessary—to ensure your business operations continue smoothly while we secure your roof.
We are highly skilled in all low-slope applications and utilize premium products from trusted brands like GAF, Mule-Hide Products, and Firestone Building Products. Depending on your building's needs and budget, we install Single-Ply Membranes (TPO & PVC), traditional layered Built-Up/Modified Bitumen systems, and liquid-applied coatings. Many of these systems come with extended guarantees of up to 20 or 25 years.
We start every project with a free complete diagnostic evaluation. For commercial flat roofs, this process includes taking core samples of your existing roof. Core sampling allows us to check for trapped moisture within the insulation layers. If the underlying insulation is dry and structurally sound, we can often recommend a cost-effective liquid-applied coating to preserve the roof rather than performing a full structural replacement.
We provide free complete diagnostics to take the guesswork out of the process. Our experts will inspect your roof for potential problems. If the damage is localized, a patch is usually sufficient. However, if your roof is aging or showing widespread granule loss and curling, we will outline why a full replacement is the better investment.
Absolutely. We offer a standard 10-year workmanship warranty on all new installs. Because we hold elite manufacturer certifications, like the CertainTeed SELECT ShingleMaster™ designation, we can also offer enhanced protections like the SureStart™ 5-Star Extended Warranty, which covers 100% of material and labor costs for 25 years.
If your roof has been compromised by sudden damage or aging, our Residential Roof Repair team can quickly trace the leak and provide emergency tarping to secure your interior while we map out a permanent repair. We provide emergency services during business hours.
Yes, we handle the entire permitting process with local city and county building departments to ensure your residential replacement strictly adheres to the latest building codes.

Our preventative maintenance tune-up includes clearing debris from your roof and gutters, checking for loose materials, resealing pipe boots, and inspecting metal flashings around chimneys and skylights.
Improper repairs by uncertified handymen can void your warranty. Because Central Roofing holds elite designations like the CertainTeed SELECT ShingleMaster™, our repairs are compliant with manufacturer standards, keeping your existing warranties intact.
We provide free complete diagnostics to evaluate the condition of your roof. If the damage is localized to one area, a repair is usually sufficient. If your roof is over 20 years old and showing systemic signs of failure like widespread shingle curling, we will recommend a replacement.
No, we provide complete diagnostics for free. Because water can travel far along rafters or underlayment before dripping down to your ceiling, our experts will thoroughly inspect your roof to trace the exact source of the water intrusion and identify any hidden structural damage. Catching these potential problems early helps protect your property investment and saves you money on future repairs.
In many cases, we can preserve and repair low-slope roofs without a full replacement. We utilize highly reliable liquid-applied coatings that can be easily sprayed or rolled directly over many existing substrates. These methods seal leaks effectively and can even provide system warranties for up to 20 years.
We proudly serve San Francisco, CA, and the surrounding Peninsula area.
Yes, our top-tier protections, like the CertainTeed SureStart™ coverage, are transferable to subsequent owners at no cost during the SureStart period.
A manufacturer material warranty protects against defects in the physical roofing products, while a workmanship warranty covers the labor and installation process. Central Roofing provides a standard 10-year workmanship warranty on all new installations. Furthermore, because we hold elite certifications like the CertainTeed SELECT ShingleMaster™ designation, we can offer extended protections like the SureStart™ 5-Star Extended Warranty, which upgrades you to a 25-year workmanship warranty and covers 100% of material and labor costs during the initial period.
Your roof’s price depends on its size, pitch, material choice, the number of old layers that need removal, and how easy the property is to access. We start with free diagnostics, then give you a clear, itemized estimate before any work begins.
Yes, poor attic ventilation is one of the most common reasons a manufacturer will void a roofing warranty. To ensure your investment is fully protected, our installation process includes a thorough evaluation of your ventilation and skylights.
