Rotten shingles or shingles that seem to just fall out of the roof can be easily replaced with another shingle. Several in a row can indicate a problem with the roof boards and should be carefully examined for water damage or rot. Always buy an extra bundle of shingles and keep on hand for these types of repairs.
Always use the right type of tools and materials when shingling whenever possible. Roofing nails have a larger head that prevents the shingle from pull off and over the head of the nail. Never nail through an exposed part of the shingle, only nail where the next row will cover.
Ridge shingles are the singles that are placed across the peak of the roof, known as the ridge, to provide a waterproof cap to the roof. If these shingles are damaged or are coming off it is a good idea to get a roofer in to examine the roof and give you an estimate for a full replacement or a repair.
