Occasionally, the answer is obvious: a cavity in the roof, missing shingles, leaks, or the presence of animals in the attic. Sometimes, the indications that you need a new roof are more subtle. If your roof is older than 12 to 15 years, replace it to avoid any problems from a damaged roof.
The durability of your roof will depend on its materials, installation, and ventilation, making it difficult to provide a definitive answer. A robust, well-constructed roof will typically last between 12 and 15 years. This number can reach 30 or more, depending on the quality and variety of shingles you select and the underlayment of your roof.
Given that each roof is unique, the cost of each top will vary. When determining the cost of your new roof, roofing contractors consider the following factors: size, removal of the old roof, design, shape, materials, and obstacles such as chimneys, skylights, and vents.
According to Better Homes and Gardens, forty percent of a home's exterior appeal is determined by the condition and appearance of the roof. If your roof is in poor condition or needs significant repairs or replacement, you may need help attracting bidders when selling your home.
