7 Residential Roofing System Performance Threats

When choosing a new residential roofing system, most homeowners tend to rank function above form. Aesthetics and architectural style are important, but customers naturally want their new roof to last as long as possible.

Residential Roofing System Performance Threats

A professional roofer can recommend high-quality, durable rooftop materials capable of protecting your home for decades. However, roofs do have a few natural enemies. Below are the top seven threats that can compromise your residential roofing system’s performance.


How much sunshine hits your rooftop each day? Over time, heat and ultraviolet rays can cause roofing materials to deteriorate. The effect on system performance is typically worse on roof surfaces that face west or south.


When rainwater gets underneath a roof, the support structure can begin to rot. The extra moisture also encourages the growth of mold and mildew within the roofing material, which can spread to the interior walls and ceilings.

Heavy Wind

High winds can lift the edges of a rooftop, blowing away shingles and allowing water and debris to work their way into the roof system. Extremely heavy wind can create extensive damage to most types of roofing materials.

Snow and Ice

As snow melts, it can refreeze at the rooftop’s edge, where the surface is cooler. This causes an ice dam to form, which can block the gutters and drainage system, which can, in turn, create irreparable damage. In addition, ice dams allow water to back up under the roofing materials, which leads to roof leaks and deterioration.

Moss and Algae

When some types of roofing materials become moist, moss and algae can grow. Not only is this growth unsightly, it also leads to roof leaks and the development of mold and mildew.

Poor Ventilation

Ventilation has a profound effect on your roofing system’s performance. In a poorly ventilated attic, condensation builds up inside and underneath the roofing materials. If the problem isn’t quickly addressed, the roof structure can deteriorate.

Overhanging Tree Branches

Trees may not seem all that threatening to your roof’s performance, but overhanging branches can cause trouble. Tree limbs can scrape and gouge roofing materials when the wind blows, and falling branches can create significant damage. Fallen leaves can block drainage systems or stick to the roof and promote rot.
