Slate is one of the most aesthetically pleasing and durable of
all roofing materials. It is indicative at once of the awesome powers of
nature which have formed it and the expertise and skill of the
craftsman in handshaping and laying it on the roof. Installed properly,
slate roofs require relatively little maintenance and will last 60 to
125 years or longer depending on the type of slate used for the roof,
roof and tile configuration, and the location of the property. Some
slates have been known to last over 200 years although that would be
rare in Oklahoma.
Historic slate roofs should be repaired rather than replaced whenever
possible so it's important to make sure you are working with an expert
at historic roof restoration.
Before replacing a slate roof, an experienced historic roofer needs
to check for isolated damage, corroded and worn flashings, leaky
gutters, poor ventilation in the attic, and other possible sources of
moisture that could be causing the damage. All too often slate roofs are
mistakenly replaced when, in fact, they could have been effectively
Broken, cracked, and missing slates should be repaired promptly by an
experienced slater in order to prevent water damage to interior
finishes, accelerated deterioration of the roof and roof sheathing, and
possible structural degradation to framing members.
If repair is not possible and a new slate roof must be installed, it
is important to remember that more than just the replacement of the
slate is involved. The old slate should be removed to prevent
overloading of the roof timbers.
Deciding whether a historic slate roof should be repaired or replaced can be difficult so trust our restoration roofing specialist to give your roof a thorough check.
