About Aztec UK Ltd

Owned by Aztec Washer Company in California, USA, and with an affiliate in Poland, Aztec has a wide reach of distribution. Aztec offers an extensive product line to suit almost any enquiry. Our closed-top Master Flash® products and our Master Flash® Fix-a-Flash allow for holes to be plugged. A Master Flash® Maxi can suit large pipes of up to 724mm, and our Master Flash® Residential range is perfect for slanted roofs. Our rubber flashing series can offer solutions for any problem regarding chimneys, stoves, twin flue walls, metals roofs, pitched roofs (both with a typical and an extreme slant), and even yurts.  

Our simple on-site customization allows for easy installation and Aztec’s flexible designs meet virtually all roofing needs. Sleeve suppleness accommodates vibration and pipe movement caused by expansion and/or contraction.

Aztec Washer Company, USA is family owned and operated. Created in 1968, they were one of the first bonded-washer manufacturers in the world. Since then, Aztec has only grown and now we hold a prominent position in the marketplace for our Master Flash® roof flashings, Master Seal® washers, and Master Coat® painting. With over 50 years of experience, we have had time to perfect our range and are proud to be in a leadership position in the industry.

Here in the West Midlands, Aztec UK holds a large amount of stock to meet both standard and vast volume demands with fast shipping and a rapid turnaround on orders. A close working relationship with affiliates in both the US and in Europe allows for the right parts, the right quantities, and specific requests to be met quickly for our customers.

All stages of our manufacturing process of Master Flash® and Master Seal® products are controlled by ourselves. From the purchase of raw materials to the unique bonding process employed on products, Aztec professionals oversee the full operation. As a Certified ISO 9001 Company, we take pride in product quality and the total satisfaction of our customers.

At our manufacturing plant, we employ a rubber chemist and have state-of-the-art inspection equipment. United with stringent quality controls, this provides a guarantee that our high standards are met continuously.

When coupled with numerous elastomers, metal, and alloy options, our tooling capabilities mean that we can offer a massive variety of roof flashings and sealing washers, can continue to innovate, and launch new products.
