Many manufacturers of composite shingles now offer superior protection from our climate such as a “Scotch guard” coating to inhibit growth of algae and moss on your new roof as well as solar reflective shingles with specially treated granules to reflect solar energy out and away from your home to help combat energy costs, both a benefit to you, the homeowner.

Slate or Tile Shingle
Often in the Portland area, historic homes or buildings were constructed using a natural slate or tile roof shingle to compliment the architectural style of the structure. Although natural slate and tile shingles can be the longest lasting materials one can choose for a roof, they are also incredibly heavy compared to an architectural or wood style roof, they are also prone to chipping or cracking, and are more difficult to install and repair.
Natural slate and tile types of roofs are still available if you want period correct materials in your home, there are also alternatives, like manufactured tile or slate. They give the same period correct appearance but cut down on install and material costs. But in the long run, whichever you choose, both these options are by far the most labor-intensive, the expensive route to go.
With the correct, properly informed contractor a home with an existing aging or failing slate or tile roof can be replaced with era correct material or converted to a more modern composite roof while maintaining a period correct appearance. The choice is yours.
