The highest quality wood roofs require the highest quality wood to start with. We use only cedar from Waldon Forest Product, supplied by Wilson Enterprises. Their cedar products are superior to any wood that we have seen from other suppliers. Metal flashings, valleys, and counter flashings that we use are 16 oz copper, .24 gauges PacClad steel or .040 PacClad aluminum. We follow the standards of the Cedar Shake & Shingle Bureau. We now use only stainless steel fasteners to install the roof. Fire treated wood should only be installed with stainless due to its corrosiveness in our opinion.​​


Slate is probably the best roof that can be installed on one’s house. It is expensive roof, which is beautiful and lasts a lifetime. Slate is very difficult to install properly. The initial planning is key to a successful project. Some slate roofs are fairly routine. Other slate roofs with multiple colors blends, intermingled thicknesses or graduated roofs are much more difficult. The blending of colors and various thickness of slate has to be artfully done to achieve a perfect roof. Over the years we have done many slate roofs for top architects, builders and homeowners.


We install 3 ply modified bitumen membrane roofs consisting of a fiberglass base sheet, a smooth surfaced modified bitumen inner layer, and granular surfaced modified bitumen as a top layer. 24 gauge PacClad steel or 16oz copper are used for flashings. This is an excellent choice for a flat roof that will stand the test of time.


We repair all type of roofs, flashings, skylights and wood replacement.


We install expertly done chimney flashings, saddles and gutters. We have worked with two of the best gutter and sheet metal contractors on the North Shore for complicated metal bays, metal roofs, and custom made soffit and fascia, ridge caps, and custom made gutters and downspouts.
