When to start thinking of a roof replacement may not be entirely clear unless you find yourself in a situation like the one in the photograph in this post. Terrible right? But, over the years, how do you know that it’s time to start the process of replacing your roof?

Roof warranties can vary between 20 and 50 years. That depends on the type of roofing supplies with which your roof was built. However, it’s not a guarantee that that timeframe should be when you start thinking about roof replacement.

Factors such as the type of roof or the construction process influence the lifespan of your roof. How do you know then if your roof needs replacement? How long does a roof last for real?

Let’s take a look at the four roof replacement factors that influence your roof’s lifespan:



Asphalt shingles are the most common option for roofing structures in the Bay Area. Four out of five homes have this roofing material. Asphalt shingles are cheap, aesthetic, easy to install and durable. Shingles are one of the most significant elements of a roofing structure. With proper installation, asphalt shingles can last at least 30-years.



The underlayment is decisive when protecting a roof. It’s installed over the roof deck and is made of waterproof material to protect the roof from rain, snow or ice. A good investment in underlayment for your roof is an excellent choice. This will add years of life to your roof and increase your house’s value.



Every home is unique so is its ventilation. A proper ventilation system in the attic can add a considerable amount of years from one roof replacement to the next. A vented roof can prevent the attic from getting moist and warm. It also prevents ice damming or snowmelt over your roof.


Roof installation

Can you remember how your roof was installed? There are hundreds of ways to build a roof, and each of them influences its duration. Specific steps can’t be omitted during the assembly of a roof, no matter what type it is. At the same time, some other particular conditions depend on the roofing supplies or your home’s location.

Keep in mind that a proper roofing installation is a crucial factor in determining your roof lifespan. If the time for getting a roof replacement is getting closer, choose a trusted roofing agency that guarantees quality work.
