Entire replacement of a slate roof is very expensive. About 4 times the cost of compostition shingles.

On the flip side, a slate root has a life expectancy of over 100 years, compared to 25 or so for composition. If there are a few broken slate tiles, new ones can be installed. They add a nice look to the house that many buyers like. In fact, I am closing on a house Dec 30th that has a slate roof.

I am having a contractor look at a slate roof tomorrow morning. Has anyone out there had one of these replaced before? I don’t know if this one needs to be replaced, but I was just wondering if someone had one replaced could they give me some idea of how much it would costs?

Check with insurance companies in your area and see if they provide a discount for UL 2218 impact resistant shingles. Insurance companies in certain areas of the country can give as much as a 30% discount on premiums for this type of shingle.

Some brands are very cost competitive. This could also be a good selling point for the house.

On the “This Old House” series they put an artificial slate roof on Silva’s house. Their comment was the cost is about it being a third the cost of true slate and it would last 60 years.

I’ve replaced a slate roof on a rental as slate was too costly. On another property I have been repairing a slate roof to extend its life. Repalcing broken slates, missing nails etc. Never tar a slate roof that will shorten its life not extend it. With proper care it will last 100 years!

Based on HOMETECH REMODELING AND RENOVATION COST ESTIMATOR 1999 EDITION for "Pensylvania Slate " including nails, staging, felt and ridge slates-does not include removal-, 4-6/12 slope 885.00 per square and 7-12/12 slope 867.00 per square.

Roughly eight times the cost of a standard 20 year three tab shingle.
