How Often Should You Replace Your Roof?

A homes roof is the protective layer from the external conditions that help keep your home dry and warm. It’s also an item that homeowners don’t want to repair or replace often. On average, a roof will need to be replaced every 15 to 20 years, depending on the materials used, ventilation, and climate factors such a humidity, cold, and heat. Consider having a roofing contractor to perform inspections on your roof every couple of year to keep informed about the status of the roof of your home.


Lifespan of A Roof

The lifespan of a roof can vary from house to house, and it doesn’t matter how similar the roofs all look in a neighborhood. Many factors will determine how long your roof will last and when it will need to be replaced. A few of the elements you need to consider are:



It depends on the roofing materials that were first used on your home, and different roofing materials come with different average lifespans. If you keep up to date with typical roof maintenance asphalt shingles should last 15 to 18 years. Laminate shingles can average 24 to 30 years, but wood shingles and metals can average 30 to 40 years, and 30 to 45 years, respectively, and clay tiles can average to around 50 years.



Depending on how humid the climate is you live in, you might be replacing your roof sooner than the average lifespan. Moisture is your roof’s enemy, and areas that are prone to heavy rains, snowfall, sleet, and hail, can expect to replace their roof before it hits its average lifespan. Winter is damaging to many things, but especially your rood with the fluctuations between freezing temperatures and above-zero thaws, that lead to other problems for your roof.



Dark roofs are prone to absorb heat, which can lead to melting and cracking, and other problems when your roof is vulnerable. Again, is you live somewhere,  with a warm climate or hot summers, this can all play an effect on the lifespan of your roof.


Poor Ventilation

There’s much more to consider then the quality of shingles when thinking of roof care. There needs to be proper ventilation to ensure that your roof is not forming ice dams during the winter and that air can circulate and properly ventilate during the summer so that your roof doesn’t get too hot.



The older your roof gets, the more likely it is that it will need to be repaired or replaced. Another thing to consider, if ever buying a home, is asking for an inspection of the roof.


Final Thoughts

There’s a lot to consider when it comes to replacing a roof, but generally, most roofs need to be replaced after 20 years. But if you are noticing any problems or significant issues before that time, it might have to be done sooner. It’s essential to keep your eye out for sings od damage, such as large water stains on your ceiling, mold, or other discolorations are also a tip-off that there could be excess moisture coming through the roof. If you have a persistent leak, it could cause severe structural damage and make your roof dangerous.

A professional roofing company, like DMV Roofing Pros, can evaluate your roof and determine if it needs to be entirely replaced or if it can be repaired. Especially if every year you are doing little touches up repairs, eventually these patch-ups can add up, when it might have been less expensive to have a professional come in and evaluate and replace the roof in the first place and leave you with peace of mind knowing that right materials were used, and your roof has proper ventilation to help expand its lifespan.
