FAQs

The lifespan of a roof varies depending on several factors. These include the quality of materials used, the effectiveness of attic and roof ventilation, and the local climate conditions. All roofs will eventually require replacement, but proper maintenance can extend their longevity.

Roof deterioration is caused by a combination of factors. These include exposure to ultraviolet radiation from sunlight, extreme temperature fluctuations, wind and rain exposure, and foot traffic on the roof surface. It's worth noting that darker-colored shingles may have a shorter service life compared to lighter-colored ones due to increased heat absorption.

The splitting and cracking of wood shingles is a natural part of their aging process. This occurs primarily due to the repeated cycle of moisture absorption and subsequent drying, which causes the wood to expand and contract over time.

While it is possible to add another layer of roofing over an existing one, this practice can reduce the roof's resistance to hail damage. It's important to consult local building codes, as some areas restrict the number of roofing layers permitted. Additionally, when applying new roofing over wood shingles, potential fungus problems should be considered.

Yes, composition shingles can be repaired if the damage is minor. A professional roofing contractor can remove individual damaged shingles and replace them with new ones, maintaining the integrity of the roof.

The potential for hail damage to roofing depends on various factors, including the hail's shape, hardness, and density, as well as wind speed, roof age, and roofing material. Generally, pea- and marble-sized hail shouldn't cause significant damage to composition shingles in good condition, unless accompanied by extreme winds.

Yes, granule loss is a normal part of the weathering process for composition shingles. Small hail impacts, rain, wind, and foot traffic can all contribute to the displacement of granules over time. This process is expected and doesn't necessarily indicate immediate roof damage.

The lighter-colored marks you observe after a hail storm are not typically indicative of damage. These marks occur because hailstones remove the algae and oxidation that have darkened your roof over time. These lighter areas will gradually blend in as algae regrowth and oxidation continue.

Hail damage can vary significantly, even within a small area. Factors such as the number, size, and hardness of hailstones, wind velocity and direction, roof pitch, and the age and condition of each roof contribute to differing impacts. Therefore, homes in the same neighborhood may experience varying degrees of hail effects.

When replacing your roof, several factors require consideration. These include the original roof design, proper ventilation, changes in roof structure due to new materials, potential insulation issues in vaulted ceilings, and the availability of energy-efficient roofing options. It's crucial to address ventilation needs, consider the impact on existing trim and structures, and explore modern roofing technologies that can improve energy efficiency and longevity.
