10 Factors That Influence Roof Longevity

Oct 11, 2018

When buying a new roof, putting a premium on installation and material quality doesn’t guarantee longevity. Both are important, but overlooking the other things that contribute to premature failure can be costly.

10 Factors That Influence Roof Longevity

To maximize the service life of your replacement roofing system, Rogers Roofing recommends keeping these 10 factors in mind:

1. Local Weather

If roofs have a nemesis, it’s Nature. When choosing a product, understand how it can withstand the harshness of the seasonal elements. If your chosen roof has weak resistance to weathering, don’t expect it to last a lifetime.

2. Thermal Cycling

The fluctuation of surface temperatures has an impact on all roofing components. Most materials expand when it’s hot and contract when it’s cold. This cycle happens daily, and its effects worsen the greater the differences between high and low temperatures are.

3. Roof Color

Any experienced roofer would attest that darker colors tend to absorb more heat than lighter ones do. But then again, reflective granules and finishes can be considered cool even when they’re closer to black than they are to white.

4. Attic Ventilation

A hot and moist attic helps accelerate the deterioration of roofing materials above. In the summer, a superheated attic space can bake materials at the bottom as the sun fries them at the top. In the winter, a warmer roof surface increases the chances of ice damming, which is destructive in itself.

5. Elevation

The higher the location of your property’s elevation, the closer your roof is to the sun. In turn, the effects of ultraviolet (UV) radiation heighten. As a result, exposed components would age more quickly.

6. Pitch

Flat roofs are more prone to damage than sloped ones are because they don’t drain rain and snowmelt efficiently. Even if you use specialized components, a low-slope roofing system would wear faster due to hydrostatic pressure and prolonged moisture exposure.

7. Greenery

Trustworthy roofing companies would advise you to trim tall, nearby trees for many reasons. Overhanging branches can bruise the materials with strong winds, fill roof planes and gutters with debris, and give wildlife easier access to your property.

8. Shade

Too much sun isn’t good for roofs, but too much shade can be just as bad. Shaded sections set the stage for moisture accumulation, allowing moss and algae to run amok.

9. Foot Traffic

You may know how to walk on of your roof safely, but the very act on stepping on certain materials could suffice in causing irreversible damage.

10. Maintenance

Last but not the least, improper maintenance will doom any roofs to premature failure. Waiting for leaks to occur before you call in professionals for an inspection can shorten the time between replacement jobs.
