When most people think of roofing shingles, they are actually thinking of asphalt shingles, the most common type of shingles in the country. Asphalt shingles are made from asphalt re-enforced with either organic material or fiberglass and they are coated with small metallic surface granules that protect the roof from UV-rays that speeds deterioration. Asphalt shingles come in a wide range of colors, sizes and styles. During severe storms asphalt shingles can be seriously damaged and require repair or replacement.
On an asphalt roof, hail damage looks like a dark spot, or bruise, where the roofing granules have been knocked away. In some cases you may find holes, cracking, or missing shingles on roofs with hail or storm damage. After a tornado, you may notice split seams and torn or missing shingles. This can result in leaking and serious water damage, which can lead to mold formation and wood rot, which can compromise the structural integrity of your roof resulting in collapse.
In severe wind storms, it is common for shingles or sections of the roof to be missing altogether.
On other types of roofs, including shake (wood), metal, tile and slate, damage can include broken or cracked shingles, missing shingles, torn or split seams, and missing sections of the roof. If a tree limb or other debris has fallen onto your roof during the storm, you may have structural damage, and will want to exercise extreme caution.
