As homeowners we all desire to keep a roof over our heads for as long as we live in our homes. We depend on our roofs to keep Mother Nature off of us and our walls to keep her out. She can put up a fight at times and we have to protect ourselves by maintaining our homes. Depending on the geographic region we live in we can be subject to a wide variety of storms. In New England we have harsh winters, in the Midwest and Great Plains we are pounded by strong spring winds, hailstorms and tornadoes, in the West relentless heat and so on.
What kind of damage can we expect when Mother Nature comes calling? Storms can wreak absolute havoc on a roof. Strong winds, hail or even heavy rains can adversely affect a roofing system when it is not properly maintained. Slate and tile are extremely tough materials and very long lasting. Hail can damage these surfaces in several ways. When the hail is large, when the slate has deteriorated or has become soft and thin or due to incorrect installation, the roof can become susceptible to hail damage.
It does not take a lot of precision to find hail damage on any roof surface, it is pretty evident, usually it looks simply like a hole in the slate itself. Hail can either break or puncture the slate and can dent metal flashings. Where precision comes into play is in the repair of it. Hail can damage a slate roof but in the majority of cases it can be repaired. Repair in this manner replaces the damaged slates with matching slates. You must match the slates as close to the original as possible. This is to maintain the aesthetic value of the roof. Newer slates do not age the same as the older original slates and this can plainly be seen.
In repairing slates from hail damage the adjoining flashings have to be replaced also. Dented flashings can be a hidden source of leaks that can cause interior damage.
Here are some other examples of the havoc storms can cause.
