How Long Should The Average Roof Last?

Many different factors have an effect on a given roof’s lifetime. While most cannot be controlled, at least factor should be maintained, so that it can limit the effect of the other factors.

The type of roof on a given building determines to a large extent the amount of time that could pass before that same roofing would need to be replaced. A roof made of asphalt shingles should last for 20 to 30 years. If well maintained, a tile-covered rooftop should last for 50 to 60 years.

The level of maintenance that roofing receives has a huge effect on its lifetime.

Regular inspections by Roofing Contractor in San Jose allow for the detection of problems at an early stage, in other words, at a point where the detected problem is easy to fix. An effort to watch for certain interior signs can work to supplement any inspections.

Obviously, the appearance of a leak is a bad sign. Still, some changes signal problems before a leak might get noticed. For instance, there could be stains on the ceiling. Improper installation can also cut into any roof’s ability to provide the desired level of protection for an extended amount of time. For instance, the installer needs to place the elements on the sides, and on those spots where the roofing meets any one of the building’s surfaces. That would include a spot like the sides of a chimney.

How weather conditions affect a roof’s lifetime?

Storms can subject roofing to a combination of winds and some form of precipitation. Rain should roll off of a rooftop with a steep slope. Still, the rainwater needs to fall into a clean and debris-free gutter system, so that it can be directed to the ground.In other words, gutter cleaning must be part of any planned roofing maintenance work.

That fact holds true, whether the water flowing into the gutter system has come from melting snow, melting ice or rainwater. Regardless of its source, it should be directed towards the ground. Intense heat can also affect the condition of a rooftop. It might cause the shingles to curl, or crack. Because homeowners cannot control the intensity of the sun’s heat, their efforts need to focus on good roofing maintenance.

Homeowners can feel the sun’s heat, but not one other factor that could shorten the length of a roof’s lifetime. In fact, human eyes cannot even see that particular factor. It is the sun’s UV rays.

UV rays can change the color of shingles on an asphalt roof. Yet those same rays lack the ability to change the color of metal or tile roofing. That is why it is easier to replace a broken tile than it is to replace a damaged shingle.
