Roof Repair and Maintenance: 5 Preventative Measures

Replacing a roof is more costly than repairing a roof. An average roof that is between 2,200 and 2,600 square feet can cost anywhere between $1,000 and $4,000 for a DIY homeowner to replace. Hiring a professional roofer to replace the roof can cost anywhere between $2,000 and $8,500. The standard unit of measure for roofers is a ten foot by ten foot “square,” which means the average roof is between 22 and 26 squares. Roofers charge by the square.

One way to head off a roof replacement is roofing repair and maintenance performed annually or semiannually. Annual or semiannual roofing repair and maintenance addresses these issues before they become major problems. Here are five preventative measures taken during a typical roofing repair and maintenance service:

Visual Inspection

The roof is visually inspected during roofing repair and maintenance service. Any signs of standing water or sagging may indicate where possible leaks may occur. Similarly, shingled roofs and slate roofs are inspected for missing, curling, or damaged shingles or missing or damaged tiles that may allow water to leak through the roof. Tile or shingle repair, or tile or shingle replacement, may be needed to maintain the integrity of the roof.

Inspect and Repair Flashing

Flashing around vents, chimneys, or other openings in the roof are inspected to make sure they are undamaged and seal the vents, chimneys, or other openings from water leaks. If the flashing is bent or has pulled away from the roof, the flashing may need to be re-positioned and re-caulked.

Check for Fungus and Algae

The roof surface may be inspected for mold, fungus, or algae, which can cause the roof material to break down and leak. If leaks occur, the mold, fungus, or algae may make its way into the house.

Inspect for Rust

Metal on and around the roof may be inspected for rust during roofing repair and maintenance. Rust around vent pipes, gutters, or flashing may indicate water damage or leaks. Depending on the amount of rust, the rusted part may need to be replaced or painted.

Check Fascia and Soffit

During roofing repair and maintenance, the fascia and soffit may be checked for cracks and rotting, as well as insect or animal damage. Cracks, rotting, and other damage to the fascia or soffit could allow water or invasive animals and insects to enter the attic.


You change the oil in your car so the engine will last as long as possible. You brush and floss so your teeth will last as long as possible. Why not do the same for your roof? Roofing repair and maintenance can find and address potential problems before they necessitate replacement of the roofing.
