  • What To Ask References
    Interviewing Previous Customers About Their Experiences with a San Mateo County Metal Roofing Contractor

    It’s best to select a Diamond Certified metal roofing contractor because all certified companies have passed an in-depth ratings process that most other companies can’t pass. If you want quality from a metal roofing company in San Mateo County and the greater Bay Area, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews. That’s because all research is performed in live telephone interviews of actual customers.

    If you can’t locate a Diamond Certified metal roofing company within reach in San Mateo County, including the smaller cities of Brisbane, La Honda, Princeton by the Sea, San Gregorio, Palomar Park, and Pescadero, you’ll have to do some research on your own. If you do, it’s wise to call some references provided by your metal roofing company.

    Remember, though, that references provided to you by the metal roofing contractor are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do phone references on your own, specifically request a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    1. Were you satisfied with the services from (metal roofing contractor name)?
    2. Did the metal roofing contractor keep you up to date with the status of the metal roof installation? Or did you have to call to get information?
    3. If you live in one of the smaller cities such as Millbrae, Moss Beach, Sharp Park, Emerald Hills, Half Moon Bay, Hillsborough, and El Granada, did they charge extra to travel to your home?
    4. Did the metal roofing contractor show up on time?
    5. If you need a metal roofing company in the future, will you consider hiring this metal roofing company?
    6. Did the metal roofing contractor start and finish the work on time?
    7. Would you recommend this metal roofing contractor to your family and friends?

    • Do not sign a contract or any document until you have thoroughly read through it and filled in any blank spaces.
    • Do not make final payment until the work completed meets agreed upon specifications and building code requirements.
    • Do not sign a contract that uses vague terms. Make sure that all terms are specific regarding project requirements and the work that will be performed.

    Figure out a Payment Schedule with a Metal Roofing Company from San Mateo County
    Once you have negotiated a final price for the roofing project, you should agree to payment terms. You should either pay a portion of the job at certain stages such as after removal of old roofing, once products are delivered, or at the completion of the job, or you should wait until the entire project is completed before making payment.

    Time to Let the Metal Roof Work Begin
    If you have faithfully followed all of the above steps, you can feel confident that you have hired the best metal roofing company for the job. You have done your research, made comparisons, negotiated for a fair price, and signed a written contract.

Frequently Asked Questions
Frequently Asked Questions for Metal Roofing Installers

Q: Why choose a Diamond Certified metal roofing contractor?

Q: Why choose a Diamond Certified metal roofing contractor?
A: Diamond Certified helps you choose a metal roofing company with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only metal roofing companies rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified metal roofing company.

Q: Is a metal roof more expensive than a typical roof?
A: Metal roofing is a premium home product so it costs more than an asphalt shingle roof. However, a metal roof is comparable in price to cedar shake roofing or tile roofing. Also, it is less expensive than a slate roof. The good news is that a metal roof typically comes with a 30 to 50 year warranty. It adds to the resale value of your home and will help you save money on your energy bills.

Q: How can I know that a metal roof will match my home and roofing style in my neighborhood?
A: Today, metal roofing for residential structures is made to look exactly like roofing materials that are commonly used such as cedar shake, asphalt shingle, slate roofing, or cedar shake. However, it’s more durable and stronger. Metal roofing comes in a wide variety of colors, patterns, and styles, so you should be able to match the style of your home and neighborhood.

Q: Is lightning attracted to metal?
A: Lightning is attracted to the highest point. So a metal roof is not more likely to be hit by lightning than any other type of roof. However, metal roofs do dissipate an electrical charge, so if, by the rare chance your home is hit by lightning, a metal roof may help prevent your home from catching on fire.

Q: Can I walk on a metal roof?
A: Typically metal panel systems can support the load of an average individual walking on them. But you should take care to not cause damage to the roof because of abrasion or collapsing of the raised portion of the panel—as with any system.

Q: How much does metal roofing weigh?
A: Metal roof systems commonly weigh between one to three pounds per square foot. The metal gauge and profile of the panel determines the weight. Compared to other systems, metal roofing systems are considered a lightweight roof covering.

Q: How far can I span with metal roofing?
A: The profile, gauge, and width of the panel itself determines span capability. In order to determine if the panel meets the actual performance requirements for your project, consult individual load tables and test results.

Q: How much longer can I expect a new metal roof to last versus common roofing such as wood  shingle or asphalt?
A: A metal roof usually lasts two to three times longer than a regular roof. In other words, a metal roof can last 40 to 60 years or more. Typically, an asphalt roof lasts between 12 to 20 years, depending on pitch and climate. Asphalt roofs decompose but a metal roof will never decompose. Metal roofs retain their good looks and durability year after year after year.

Q: Is metal roofing noisier in bad weather than cedar shake, slate roofing, tile, or asphalt?
A: This is a common misconception about metal roofing. Metal roofs are often installed over a solid substrate. Furthermore, attic space and insulation provide even of a sound barrier. Research proves that metal is not any noisier than traditional roofing systems. In fact, you’ll hear more outside noise from windows and walls than your metal roof.

Q: How will a metal roof endure extreme weather?
A: A metal roof has the ability to withstand decades of abuse from high winds, hailstorms, heavy snow, wildfires, and other forms of extreme weather. Metal roofing has a wind rating of 120 mph—equal to an F2 tornado. It is also the roofing system of choice in locations of heavy snow because it protects the structural integrity of a roof. It eliminates ice damming at the eves so water won’t back up and create leakage into your home. Furthermore, it also adds protection if burning embers land on your roof. To top it off, metal roofing may even save you money on your homeowners insurance.
