Roof replacement is very likely one of the most expensive home improvement projects that you will complete. For this reason, you want to make sure that you are making the best decisions when it comes to when and how the replacement is completed. So, how exactly will you know when to contact a professional for the roof replacement service? Find out about a few distinctive ways you can figure this out.
Consider the Roof's Age
One of the easiest ways to figure out when you need a new roof is to use the age of the existing roof structure. Most roofs will have an age range that you should pay attention to. And, you can use the date of the initial installation to figure out the age. This is one reason why it is always wise to keep the original paperwork whenever a home construction project, service, or installation is completed.
You also have to look at the roofing material. When it comes to traditional asphalt shingles, these will last 15 to 30 years. High-quality architectural ones or any other shingle product that is made with a thick construction will likely last for 25 to 30 years. Any clay or terra cotta product can withstand up to 50 years of abuse and metal roofing can stay strong for 70 years.
The age can give you a rough guideline, but you should also think about the weather in your region. Is your roof exposed to hurricane-force winds? Do ice dams form in the winter months? Or, has your roof been exposed to any hail? If the answer to any of these questions is yes, then your roof may not reach its typical lifespan.
Look for Signs of Serious Damage
You may notice the occasional shingle tear or rip and this can be addressed easily by replacing each shingle individually. However, certain kinds of damage, even when it is isolated, can indicate that the roof is starting to age. This is true if shingles start to tear or dislodge in a way that the underlying nailing edge is exposed. When this starts to happen, shingles have aged to the point where they tear along the more protected areas of the shingle. And, the exposed nails can lead to leaks in a short period of time.
Other concerning issues include anything that indicates that water penetration is a problem. The development of mold or the growth of moss or other plants is a sure sign of this. Also, you want to look for signs that the shingles themselves are breaking apart. For example, if the top part of the shingle has started to deteriorate, then the base will no longer have the strength alone to protect your home.
