Repair or Replacement Guide to Wood, Slate, Tile and Asphalt Roofing
Should I repair or replace my roof? This is one of the most common questions asked. The typical contractor will often recommend replacement along with an insurance claim. Below is a guide to follow as you consider which choice is right for you.
Age: How old is the roof compared to the serviceable life of the roof. Common functional lives are;
ROOFING LIFESPAN
- Tile Roofing
- Slate Roofing
- Wood Roofing
- Asphalt Roofing
Amount Damaged: Calculate the number of damaged and missing shingles, tiles, or slates. Is the number less than about 20%? Is the roof generally in good condition? If so, the roof should be evaluated for repair rather than replacement. Also, keep in mind that the older a roof becomes, the more maintenance it will likely require.
Leaks: Determine if there are active leaks and what their source may be. Do not assume the shingles, tiles, or slates are leaking. Gutters, valleys, and flashings are more likely candidates. “False leaks” can be caused by moisture condensation in the attic due to improper ventilation.
Moisture: Check the roof rafters and sheathing for moisture stains. Poke an awl into the wood to determine if it is rotted. Remember that very old, decaying shingles, tiles, and slates will hold moisture and cause adjacent wood members to deteriorate even if there are no apparent leaks.
Flashing: Consider the condition of the roof’s flashings. Because traditional roofing is so durable, metal flashings often wear out before the slate does. Examine the flashings carefully. Even the tiniest pinhole can permit large quantities of water to enter the building. Is the deterioration of the roof uniform? Often this is not the case. It may be that only one slope needs replacement, and the other slopes can be repaired. In this way, the cost of replacement can be spread over many years.
Availability: Are new appropriate materials readily available? Even if replacement is determined to be necessary, the existing roof may have to be repaired to allow time for documentation and the ordering of appropriate replacement slates.
Overlay: Is the current an asphalt roof over a wood shingle roof? If so, it will be necessary to replace the roof as repairs are not recommended.

Slate roofing demonstrates the power of nature that formed it, the industry that shaped it, and the craftsmen that laid it on the roof! Because of the craftsmanship, environmental impact, and expense, all efforts must be made to repair rather than replace. Slate roofs can last lifetimes, up to two hundred years! The National Park Service recommends a regularly scheduled maintenance program.
