Historic Slate Roofs

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 repaired.
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.
