Overview

As a house flipper, you need to be able to inspect a property's roof and determine if it's in acceptable condition, or needs to be repaired or completely replaced. This is a critical skill because the roof is a major component of any house, impacting both its value and the safety of its occupants. A damaged or poorly maintained roof can lead to costly repairs, delays in your project, and even potential legal issues down the line.During your inspection, you'll be looking for common red flags like:

  • Missing or damaged shingles
  • Signs of leaks or water damage
  • Sagging or uneven rooflines
  • Improper flashing or ventilation

Keep in mind that the age of a roof is a key factor. Most asphalt shingle roofs last 20-25 years, but climate, maintenance, and the quality of the original installation can all affect its lifespan. So, even if a roof doesn't show obvious signs of damage, its age might indicate it's nearing the end of its useful life.

Focus Areas

These focus areas will guide your inspections to determine if an item needs repair or replacement. Prioritize safety, then evaluate style against market trends and comparable properties, and finally assess the item's condition for its remaining lifespan.

Things to Look For

Safety and Code Considerations

  • Multiple Layers: Check for multiple layers of roofing. Building codes typically limit the number of layers to two. Multiple layers can trap moisture, increase the weight load on the structure, and void warranties.
  • Proper Flashing: Inspect flashing around chimneys, vents, and skylights to ensure it's properly installed and sealed. Missing or damaged flashing can lead to leaks and water damage.
  • Ventilation: Ensure adequate attic ventilation. Poor ventilation can cause moisture buildup, leading to premature shingle deterioration and potential structural issues.
  • Structural Integrity: Look for signs of sagging, unevenness, or damage to the roof structure. This could indicate underlying problems that need to be addressed.

Style and Comparable Considerations

  • Curb Appeal: Assess the overall appearance of the roof. A worn or outdated roof can detract from curb appeal and impact the property's value.
  • Shingle Style and Color: Consider the style and color of the shingles in relation to current market trends and the architectural style of the house. Upgrading to architectural shingles can enhance the look and value of the property.
  • Neighborhood Standards: Drive through the neighborhood and observe the types of roofs on comparable properties. Ensure your renovation choices align with the neighborhood standards and buyer expectations.

Condition Considerations

  • Shingle Wear and Tear: Inspect shingles for signs of aging, such as curling, cupping, cracking, or missing granules. Pay close attention to areas that receive the most sun exposure (typically the south-facing side).
  • Flashing and Seals: Examine the condition of flashing around chimneys, vents, and valleys. Look for cracks, gaps, or signs of deterioration that could lead to leaks.
  • Underlayment: If possible, inspect the condition of the underlayment for signs of damage or deterioration. This layer beneath the shingles provides an extra barrier against water intrusion.
  • Previous Repairs: Look for signs of previous repairs, such as patched areas or mismatched shingles. This could indicate recurring problems or underlying issues that haven't been fully addressed.

Pro Tip

When inspecting a roof, pay close attention to the south-facing side, as it receives the most sun exposure and may show more signs of wear and tear. Always prioritize safety when accessing roofs. If you're not comfortable working at heights, hire a qualified roofing professional to conduct the inspection.

Measurements

To estimate roofing costs and create a scope of work, you'll need to measure the roof's area. Here's how:

  • Calculate Square Footage: Measure the length and width of each roof section. Multiply the length by the width to get the square footage of each section. Add up the square footage of all sections to determine the total roof area.
  • Determine "Squares": Divide the total square footage by 100. This will give you the number of "squares" needed for the roof. A "square" is a standard unit of measurement for roofing materials, equal to 100 square feet.
  • Perimeter Measurement: Measure the perimeter of the house to estimate the linear feet of drip edge and gutter needed.

Safety Tip: Always prioritize safety when accessing roofs. If you're not comfortable working at heights, hire a qualified roofing professional to conduct the inspection.
