How can I know when my roof needs repair or replacement?

Roof Shingles

There are a few things to watch for when assessing whether repairs need to be made:

  • Broken and Cracked Shingles - Too many broken and cracked shingles will compromise your roof’s integrity. These should be repaired to ensure proper protection.
  • Wide Gaps - When roofing materials age, they will shrink. This can lessen the protective covering of the roof and allow moisture to seep into the attic. Gaps should be about 3/8” wide. When they become ¾” or more, it is time for repairs.
  • Shingle Curling - Curling at the edges of the shingles is a common sign that they are aging. This can sometimes be observed from the ground and is an indication that your roof needs attention.
  • Mildew and Algae - Shady roofs can have fungus and algae grow on them. This type of growth can be limited by trimming trees to allow sunlight to reach the surface.
  • Age of the Roof - Asphalt shingles, the most common roofing material, will last about 20 years. If your roof is approaching its suggested lifetime, consider having a professional take a look.

If you are unsure about the condition of your roof, a Global Property Inspections professional can inspect it and give you a proper assessment.

For keeping your roof in good condition, hire good roofing company which provides regular inspection and maintenance of the roof.
