When to Replace Your Roof, and Other Roof Questions You Might Have

Updated: Jun 20, 2023

The lifespan of a roof can vary greatly depending on the material and environmental factors.

However, there are a few signs that your roof may be reaching the end of its life:

  1. Age: If your roof is over 20 years old, it may be time to start thinking about a replacement.

  2. Shingles: If your shingles are curling, cracking, or missing, it's a sign that they are no longer protecting your roof properly.

  3. Granules: Look for granules in your gutters or downspouts. If your shingles are losing granules, it's a sign that they are nearing the end of their lifespan.

  4. Water Damage: If you notice water stains on your ceiling or walls, it's a sign that your roof is leaking and needs to be repaired or replaced.

  5. Energy Bills: If your energy bills are higher than usual, it could be a sign that your roof is no longer providing adequate insulation.

What Does a Failing Roof Look Like?

If you suspect that your roof is reaching the end of its life, there are a few things to look for:

  1. Dark Streaks: Algae and moss growth on your roof can cause dark streaks and stains, which can be a sign of moisture damage.

  2. Sagging: If your roof is sagging, it could be a sign of water damage or structural issues.

  3. Missing Shingles: If your roof has missing shingles, it's no longer providing complete protection from the elements.

  4. Cracking and Curling: If your shingles are cracking or curling, they are no longer protecting your roof from water damage.

Types of Roofing Materials

There are several types of roofing materials available, each with its own advantages and disadvantages:

  1. Asphalt Shingles: The most common roofing material in the US, asphalt shingles are affordable and easy to install. However, they have a shorter lifespan than other materials and may not be as energy-efficient.

  2. Metal: Metal roofs are durable, energy-efficient, and low-maintenance. However, they can be expensive to install and may not be suitable for all architectural styles.

  3. Clay or Concrete Tiles: These materials are durable and energy-efficient, but they can be heavy and expensive to install.

  4. Slate: One of the most durable roofing materials available, slate is also expensive and heavy.

Roofing Costs in Ohio

The cost of a new roof will depend on the size of your home, the type of material you choose, and the complexity of the installation. In Ohio, the average cost of a new asphalt shingle roof is between $3 and $5 per square foot. A metal roof can cost between $7 and $10 per square foot, while a tile or slate roof can cost upwards of $15 per square foot.

Parts of a Good Roofing System

A good roofing system consists of several components, including:

  1. Decking: The foundation of your roof, usually made of plywood or OSB.

  2. Underlayment: A waterproof barrier that is installed over the decking to protect against moisture.

  3. Flashing: Metal strips that are installed around chimneys, skylights, and other roof penetrations to prevent water from seeping in.

  4. Shingles or Tiles: The outer layer of your roof, which protects against the elements and adds curb appeal.

  5. Ventilation: Proper ventilation
