What is the average lifespan of a concrete tile roof?
Concrete tiles are like clay tiles in many regards including their heavy weight. They are however a less costly tile roofing option, with an expected lifespan of 40 to 75 years. Tell-Tale Signs to Consider Replacement: Many cracked or loose tiles and/or leaks that don’t respond to simple repairs.
What is the average tile roof replacement cost?
The average tile roof replacement cost ranges from $8,000 to $23,000. If you’re going to repair an area instead, you’ll pay between $900 and $2,500. This works out to between $8.00 and $25.00 a square foot.
How long should wood forms stay on concrete?
Wooden forms weigh less than metal, and can be fitted and erected in small sections, and fasteners and retaining systems have been devised to allow these to be held in place with tight tolerances under the load of the weight of the concrete they will contain. Wood, however, should be treated with a form release agent if the forms are to stay in place more than 3 days or so.
