Roofing Certifications

Any time you’re paying someone to work on your home, it’s important to know the service professional you are dealing with is properly certified to do the work. Not only will this mean the work performed on your home is of the highest standard, but you will have the peace of mind that your money is well spent.

Here at Alternative Roofing, we’ve gone through the process of obtaining not one, not two, but three separate industry certifications. They’re outlined below, and we strongly recommend you ensure your Maryland roofing company has these same certifications so that you know you are getting the best roof for your money.

ShingleMaster – Offered by the CertainTeed company, the ShingleMaster certification means we are a certified residential contractor who can use the products offered by CertainTeed. With this certification we’ve shown we know how to adhere to workforce standards, produce high quality jobs, and ensure warranty compliance.

Johns Manville – Offered through Johns Manville, who has over 44 manufacturing facilities in North America. By being certified though Johns Manville, we are authorized to install any of their products in our service area; and can do so at the highest level of standards.

GAF Certified – Offered by GAF, the most fully integrated roofing manufacturer in the United States. By being GAF certified, we’ve passed the tests and proven we are qualified to install their products to a level of quality that fits their highest standards.
