Every time a homeowner hires the services of a roofing contractor, the first question that he usually asks is if there are warranties being offered and how long should a roof last? In general, a roofer will offer a 10-30 years guarantee which means that from the date of installation, the occupants can expect the roofing system to run smoothly for the next 30 years or so. Put simply, guarantees are an assurance that the quality of the roofs is high. But are these warranties true? Can you really rely on such promises?
First off, you have to identify the lifespan of your roofs based on its type of material. The question “how long should a roof last?” is not something that can be answered by merely looking at the surface of your roof. For a more accurate answer, consult a professional roofer who understands the intricacies of a roofing construction. If it's done poorly, the need for constant repair will be necessary.
Below is the list of roof types and their lifespan:
- asphalt roofs – 25 years
- cedar shingles – 25 years
- wood shakes – 25 to 75 years
- steel or metal – 20 to 50 years
- clay and slate – 50 to 100 years
