Numerous inputs directly impact the lifespan of a property’s roof, and Venture Engineering’s expertise takes the following into consideration during the roof inspection:

  • Type of Roofing Materials Used: The durability and efficiency of materials have an effect on the overall health of the roof and building. Commonly used materials may include: composition shingle, wood shake, clay, concrete tile, slate, metal/steel, tar and gravel, synthetic materials.
  •  Age of the Roof: Not only taking into account normal wear, tear, climates and weathering, materials deteriorate at different rates and the maintenance schedule should be suggested accordingly.
  • Roof Pitch or Steepness: Incline and angle causes different rates of deterioration and weathering due to the evenness (or lack thereof) of stressors placed on the roofing system. The subsequent budget may also be impacted, due to the fact that contractors often charge more for a roof with a steeper pitch.
  • Number of Layers: It is common to see certain materials layered over other materials to compound how effective the roofing system is. This may extend the life of a roofing system before an entire replacement is necessary.
  • Previous Roof Repairs:  The quality and durability of work done to previously repair the roof will impact the schedule of maintenance required.
  • Skylights or Solar Panels: If not purposefully planned for or adequately installed, these features may alter the integrity of the roofing system and demand premature maintenance.

Weathering and Natural Disasters: Whether exposed to extreme temperatures, high winds, foot traffic, or an unforeseen

How Often Should I have a Roof Inspection Completed?

Conducting a roof inspection at any given point during the ownership of a commercial property can reveal practical information on the current condition of the roof and what the asset owner can likely expect in coming years. Now is as good a time as any to have a roof inspection completed.

However, the recommended cadence is to conduct the inspection is annually. This allows for the evaluation of the systems’ condition year-over-year in a regular fashion while simultaneously allowing for a more accurate prediction and adjustment on the estimated remaining lifespan. Additionally, having the inspection done on a yearly basis can facilitate the addressing of minor deficiencies immediately, in hopes of mitigating or preventing major roofing problems.
