Many times after a storm, slates will break in the exposure (in the area of the slate that is exposed to the elements). These slates need to be repaired in a timely manner. An advantage of a slate roofing system is that the triple overlap gives a roof an added layer of protection in the meantime. The industry standard states that if more than 20% of the slate roof is damaged, the entire roof should be replaced.

Yet replacing 20 out of every 100 tiles  may do more damage than good. For this reason, the the original age of the roof also needs to be taken into account when considering replacing between 5% and 20% of the slates. Older slate roofs tend to be more brittle and weathered and color matching may not be an option.

Be aware of hairline fractures  Hairline fractures may not be visible at first but will break the slate as water creeps into the fractures. Take this into account when figuring up a 20% breakage.

Underlayment  Often older homes were installed with 15 lb. felt paper. New products on the market may be more suitable. Consider a high temp product as well.

Fastners  Slate is usually installed with copper nails. They bend easily and can be pulled from the roof to replace a broken slate. Stainless steel nails are also appropriate for slate as well.

Industry Opinion Often insurance agents look for a second opinion regarding the slate on a roof. Whether it is damage done, origin of slate or installation techniques, let us know if you need a letter of opinion based on a specific roof.
