Roof construction - an expert interview

How long should my roof last?

The lifespan of a roof can vary depending on the type of roofing material used and the local climate conditions. Asphalt shingle roofs, which are the most common type of roofing material, typically last between 15 to 30 years. Metal roofs can last up to 50 years or more, while tile or slate roofs can last up to 100 years with proper maintenance. Regular roof maintenance and inspections can help extend the lifespan of your roof and identify issues before they become significant problems. Its important to consult with a roofing professional to determine the expected lifespan of your specific roofing material and the appropriate maintenance needed.

Does my homeowners insurance cover my roof?

Homeowners insurance may cover your roof depending on the cause of the damage. If the damage was caused by a sudden and unexpected event, such as a fallen tree or hailstorm, it is likely covered by your insurance policy. However, if the damage is due to age, wear and tear, or lack of maintenance, it may not be covered. Its important to review your insurance policy and understand the specific coverage limits and exclusions related to your roof. Its also a good idea to have regular roof maintenance and inspections to identify and address issues before they become more significant problems.

Does a leaky roof need to be completely replaced?

Not necessarily. The severity and extent of the damage will determine whether a roof needs to be completely replaced or if repairs can be made. If the leak is due to a damaged or missing shingle, a simple repair can fix the issue. However, if the roof is old or has extensive damage, a replacement may be necessary to prevent further leaks and damage. In some cases, a partial replacement may be sufficient, such as replacing a damaged section of the roof rather than the entire roof. Its best to consult with a roofing professional to determine the best course of action for your specific situation.

What does a new roof cost?

The cost of a new roof varies depending on several factors, such as the size and pitch of the roof, the type of roofing material used, and the complexity of the installation. Typically, the cost for a new asphalt shingle roof ranges from N2,200 to N5,100 per square foot. A metal roof can cost anywhere from N5,100 to N 8,800 per square foot, while tile or slate roofing can cost N7,400 to N18,500 per square foot. Additional costs may include removing the old roof, repairing, or replacing damaged decking, and installing new gutters or ventilation systems. Its best to consult with a roofing contractor for an accurate estimate for your specific project.

What are the signs of a failing roof?

Some signs that a roof is failing include missing or damaged shingles, curling or buckling shingles, cracked or broken tiles, excessive granule loss, water stains or leaks, mould or mildew growth, and sagging or drooping areas on the roof. Additionally, if a roof is more than 20 years old, it may be nearing the end of its lifespan and should be inspected for signs of wear and tear. Regular roof maintenance, inspections, and repairs can help identify and address issues before they lead to more significant problems and costly repairs run.

Why is my roof stained?

There are several reasons why a roof may become stained. One of the most common causes is the growth of algae, moss, or lichen on the roof. These organisms thrive in moist environments and can leave dark, unsightly stains on the roof. Other causes of roof staining may include exposure to pollutants or chemicals, rust from metal fixtures on the roof, or debris and dirt accumulation. The staining can also be a sign of damage to the roof, such as leaks or missing shingles. Regular roof maintenance and cleaning can help prevent staining and identify potential issues before they become more significant problems.

How long does roof installation take?

Roof installation time can vary depending on several factors, such as the size and complexity of the roof, the type of roofing material, and weather conditions. Typically, asphalt shingle installation takes 1-3 days, while metal roofing can take 2-5 days due to additional steps involved such as underlayment and fastening systems. Tile or slate roofing is the most labour-intensive type of roofing.
