The average lifespan of a roof differs by the type of material used. While wood shingles last for 25-30 years, slate roofs last for 100 years or longer. Besides this, maintenance, weather, and many other factors also determine your roof’s lifespan, but it is advisable to check your roof at least once a year.

Below are some of the most common signs which should be considered when considering when to repair or replace your roof. Read on to learn more.


Hails, storms, or rain can damage your roof, which results in small cracks and holes in the ceiling. This may result in leakage into your property which also affects the attic of your home in the future.

Loose Roof Tiles

During your annual inspection, you should consider replacing your roof if you find any missing or loose tiles. It is essential to act quickly if you have a weak roof with lost or damaged tiles.


Several factors, including age, can cause sagging roofs. As a result, the rafters would have become damp, which weakens the wood. The top should be inspected and repaired or replaced as soon as possible to avoid interior damage.

Loose Shingles

A missing or cracked shingle is common after a storm or rain. The dark-colored shingles on your roof may indicate moisture on the top, which may even require replacing the roof. Inspecting your roof when you find any problems with shingles would be advisable to avoid enormous costs for replacing it in the future.

Increased Energy Bills

The spike in your energy bills may signify that your roofing needs to be repaired. It may be due to leaking warm or cool air through the roof insulation. It should be addressed immediately to avoid more significant problems in your home.

Gutter Clogs

One of the best ways to inspect your roof is to look for any granules in your gutters. The presence of asphalt or composite granules often ends up in your gutters looking like coarse, black sand. When you find sludge or pieces of shingles in your rain gutters, you should have a professional inspect them.

Calculating the Cost

After finding the issues in your roof, it is essential to calculate how much it will cost to repair them. This varies, however, depending on the damage and materials to use. Below is a list of factors in calculating the roof repair cost:

  • Issue— depending on the issue on your roof, the price varies.
