A large majority of our clients are on our annual Maintenance Program, and here’s a great example of how the Program will improve your roof! You can probably visually identify the dark, uniform-looking newer slates, so take a look at how the older slates demonstrate deterioration with brownish colors, flaking layers, and curved white ‘smile lines’. For many roofs and many budgets, a steady replacement of these worst slates every year will slowly improve the roof, avoiding future roof replacement. We want historic homeowners to know that roof replacement is NOT always necessary, but proper and preventative maintenance sure is!
