A slate roof is one of the best investments you can make in a home or other structure. The roof should be installed by an experienced slate roofing contractor. When installed properly, Greenstone's slate will last at least 100 years. See our 100 year warranty .

Hardware and Accessories

Considering the life of a slate roof, the hardware and accessories you select should be very durable. It is economically unwise to use anything but the most permanent items utilizing non-ferrous metals. There are three major items that you will need:

Flashing: Flashing should be used at all intersections of vertical or projecting surfaces through the roof or against which the roof abuts, such as walls, parapets, dormers, sides of chimneys, etc. Copper is particularly suitable for all flashings (including valleys) as it is easily worked and shaped and adjusts itself to temperature stresses.

Copper Nails: We recommend copper nails for proper installation of slate. Copper's ability to adjust to changes in temperature and its non-corrosive qualities make it an ideal solution for slate roofs. The slight savings of using non-copper nails will surely cost you more in repairs and will significantly shorten the life-span of your roof.

Snow Guards: Snow guards are rooftop devices that allow snow and ice to drop off in small amounts or melt completely before falling to the ground. Snow guards are installed on sloped roofs to prevent damage.

       Areas of greatest concern would be:
       •Entry and walkways
       •Landscaping
       •Ground mounted mechanics
       •Lower roofs, valleys and crickets
       •Gutters and roof protrusions
