ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates in general to roofs for buildings and other structures, and in particular is concerned with a durable roof covering. Furthermore, this invention is concerned with a method of installing the disclosed durable roof covering.
Various materials have been used to cover roofs of structures. Examples of such materials include shingles formed from asphalt and metallic materials such as aluminum and copper. The shingles are formed in a convenient size having a width and length. To cover a roof, a patchwork of overlapping shingles is installed.
SUMMARY OF THE INVENTION
This invention includes a durable roof covering for roofs of buildings and other structures. The durable roof covering can be formed from bendable material such as aluminum or steel. The roof covering can be pressed or otherwise formed as desired and cut to a length that matches the application, such as the width of a roof. Layers of the covering can be secured to cover and protect a roof and structure.
This invention includes a roof covering having an upper portion, a lower portion, and a retainer. The upper portion includes a nailing strip, a water stop, a lock, and a lock indicator. After a first strip of the roof covering is installed on a roof, a second strip of the roof covering is interlocked with and secured to the first strip. A retainer of the second strip is received in the lock of the first strip to secure the strips together. Successive strips of roof coverings are added to a roof until a desired area is covered.
Various objects and advantages of this invention will become apparent to those skilled in the art from the following detailed description of the preferred embodiments, when read in light of the accompanying drawings.
