Slate Valley Repair

Typically a slate roof will out-last the metal flashing-even copper flashing! Replacing deteriorated flashing is a common project for us.  This valley was on a Vermont slate roof in West Akron from circa 1920. The original style of this valley is what we call a “closed valley” with no exposed flashing. You can see that the original valley was installed incorrectly. A proper closed valley has a separate piece of flashing at each course of slate-overlapping like step flashing. This original flashing was punctured close to the center line on almost every course by the original slaters. We carefully opened the valley and it was ready for re-flashing. An “open valley” features exposed copper. Natural expansion and contraction of the slates will not wear through the center and slating nails need not puncture the flashing. This choice of valley system uses about 50% of the copper of a closed valley.

Scaffolding is dismantled, the yard and landscaping thoroughly tidied.  Please note that we were able to salvage and reuse approximately two thirds of the slates in this valley and were able to supply the remaining third of the valley slates from our own stock of vintage, salvaged slates. We take a lot of pride in our ability to match color, size and texture of slates to produce a final repair that blends unnoticed into the existing roof.

Large-Area Repairs

Slate at the bottom edge of a roof is particularly vulnerable to damage from ice build-up, improperly installed gutters and other factors.  Often, the solution is to remove several courses of slate across the roof to make the necessary repairs.

This is the Noah Carter House in the Hudson, Ohio Historic District.

It dates back to 1853.  The lower eave area needed some basic carpentry repairs. Some of the original roof deck boards were 18 inches wide- a dimension unheard of in modern construction. Andrew Hazlett (left) and Kevin Hazlett re-laid a starter course during this repair. The roof was put back together matching the original slate layout and re-using about 90 percent of the original slate.

A truly unique home in Richfield, Ohio with a truly timeless setting.

Here we have opened a problem-prone area of the roof. Carefully reworking the roof, Andrew Hazlett works with his dad Stephen. Andrew has an eye for this random-pattern slate blend. With the roof repaired, you can see that he has perfectly recreated the original stone pattern/texture.

Chimney Flashing

As with valley flashing, chimney flashing will often wear out long before slate. This large and unique chimney in Canton had been neglected for years because of its inaccessibility. By using ground and roof-top scaffolding (as well as plenty of safety gear!) we were able to safely replace the worn copper flashing.
