    Frequently asked questions


    Yorkshire Roofing is proud to inform customers that it’s a GAF-certified contractor, allowing its clients to enjoy the GAF Roofing System Limited Warranty. The GAF Roofing System Limited Warranty includes all the great benefits of the original GAF Shingle & Accessory Limited Warranty but adds Lifetime coverage on Qualifying Accessory Products.

    In this context, the word “lifetime” means the length of coverage as provided by your GAF warranty, and as long as you, the original owner of coverage, retains ownership of the property where the accessories and/or shingles are installed. Although the Lifetime limited warranty is only applicable to accessories and shingles installed on a single-family detached residence, other building types such as government institutions, corporations, condominiums or apartments, schools, and other multi-use structures can still use the warranty for up to 40 years.

    After a GAF-certified contractor like Yorkshire Roofing installs GAF products for a customer, that customer automatically enters a Smart Choice Protection Period. This period refers to the time after installation wherein the coverage received by the customer for GAF warranty is non-prorated. Once the Smart Choice Protection Period ends, any remedies provided for in the GAF warranty may not be the same as what was offered during the period.

    Choosing a GAF-certified contractor is an excellent way to secure a GAF warranty while ensuring your contractor’s service is exceptional enough to earn recognition from the GAF. Give us a call now at Yorkshire Roofing so we can provide you with a free quote on our top-notch services.

    Diamond-Certified Roofing Contractor

    A Diamond certification is only given to businesses that are able to define excellence as identified by their actual customers. Diamond certifications started way back in 1990, back when there were no computers yet and surveys were done through personal interviews and phone calls.

    Diamond Certified is an organization that believes every customer should only do business with companies of the highest quality. To truly separate which businesses provide top performance, Diamond Certified created a series of tests wherein customers can rate a business’s overall service while ensuring the results are of the highest accuracy and done with integrity.

    Only a limited number of companies earn the distinction of being Diamond Certified, which should speak volumes about how hard it is to earn the title. Diamond Certified uses a rigorous 12-step certification process wherein they survey a random sample of actual customers by telephone to get the most accurate reviews, information, and ratings about a contractor. They make sure that only actual customers are responding to their surveys to prevent any questionable results.

    Yorkshire Roofing is proud to have been Diamond Certified for 15 consecutive years, starting in 2006. With a customer loyalty percentage of 94%, Yorkshire Roofing is one of the most trusted and top-rated roofing companies providing high-quality roofing services for residential and commercial clients in Alameda and Contra Costa Counties.

    Per the latest study conducted in the subject, the average cost of a new roof ranges from $5,349 to $10,686. The amount may be higher or lower based on location. It is also highly dependent on the price of the materials and labor.

    The most typical indication of a roof problem is leakage. If you notice that water or moisture begins to seep into your attic or ceiling, it is time to have your roof inspected thoroughly.

    There are, however, a lot of signs that show if your roof has issues. Factors such as age, materials, exposure to harsh elements, are all critical.

    Another thing you can look into is the age of your roof. The average lifespan of roofs is dependent on the type of materials used. As a homeowner, you should know important information, such as the materials of your roof and its date of installation. If your roof is nearing its end of life, problems will begin to show. Aside from these, you can also check your roof for visible damage or defects. If you are using shingles, you will notice that the shingles may be misaligned or decaying. For those using a metal roof, you can check if the paint of the metal is starting to chip off.

    As architecture and design evolve, more materials are being used now for roof construction. The most common are the following:

    1. Slate
    2. PVC
    3. Shingles
    4. Metal
    5. TPO
    6. Composite
    7. Asphalt

    All of these are durable materials good enough to last. Some are tougher than others and more expensive. Some allow for more decorative leeway than other types. It depends on the homeowner which material he wants, based on his preference.

    The answer to this question varies for each type of material used.

    • Roof made out of slate, copper, and tile can last more than half a century.
    • A roof made with fiber cement shingles will last for 25 years. Composite roofs usually last for 20 years.

    However, even if the suggested lifespan of a roof can reach decades, its actual lifespan depends on how homeowners take care of their roofs. Weather is also a critical factor. Roofs that are exposed to more harsh weather conditions are expected to have a shorter lifespan.

    A roofing job is extremely difficult. Without proper training and protective equipment, it can lead to accidents and injuries. Repairing a roof by yourself is not recommended unless you are a trained roof technician. What you can do instead is minimal clean-up for your roof. Use extended cleaning brushes and sturdy ladders to clean up parts of the roof that are easily accessible. For major repairs, maintenance, and installation works, call a professional instead.

    A roofing job is difficult in itself. Without proper work conditions, it can be more dangerous and challenging. With that said, the best time to get a roofing job done is when the weather is neither too hot nor cold. Aim to schedule your roofing job when the temperature is between 50 to 60 degrees F, and when the weather is not too windy nor sunny.
