The trim "flashing" pieces are something that we make to finish our customers roofing and siding jobs. There is really Not a "standard" trim flashing, therefore we can offer almost anything our customers may need. In most cases, we will ask for you, the customer, to sketch something for us make to your dimensions. We can take either a simple sketch on the fax machine, or detailed prints emailed to our "Request a Quote" form. Please give us each of the dimensions you need, which we can cut to length, or supply in our standard 10′ lengths. The flashing pieces can cover the ends of a roofing application, or put down on corners to help keep moisture out, but the proper flashing will make almost any job look professional and clean. Please feel free to call us for more information, or help with choosing the proper flashing.
