Ice dams are a major problem for roofs in cold climates, and slate roofs aren't immune to the issue. These dams form when snow or water collects on the roof. Heat escaping from inside the home melts the snow or ice so it makes its way beneath the slate shingles. It then refreezes and can lift up the slate or cause a shingle to break. It may also result in a leak indoors when the ice dam begins to melt.
If your roof is damaged, then you may have the option of restoring or replacing it. Replacement is a good idea, but it isn't always the only option open to homeowners. Many people think that it's all about saving money because replacement can be costly, but this isn't the only benefit of roof restoration. Depending on the overall status of your roof and the nature of the damage, restoration can give you a host of other benefits such as:
Hail storms can leave your home with significant damage, especially the roof. The roof damage could be minimal or heavy enough to require a complete re-roofing. There are many myths surrounding hail damage and roofs.

The roof on your home may have a slope and asphalt shingles and an addition can be more contemporary with a flat roof. While it may be OK to use asphalt shingles on a slope roof, flat roofs need to have a durable material that is wind resistant. This can be something like roofing membranes, metal or polycarbonate roofing materials. These flat roofing materials will be more durable and wind resistant than conventional roofing shingles.
Thermal shock is the expansion and contraction of roofing materials due to temperature fluctuations. It affects all kinds of roofs, although to different degrees. Roof thermal shock is one of the reasons your roof will age and need to be replaced one day, even if you maintain it well. You know your roof is experiencing thermal shock-related damage if it is exhibiting:
Cracking of Shingles
The asphalt mix, the main material used in the manufacture of asphalt shingles, is both stiff and water permeable.
