Do I need a home inspection? Can I get by without one? That's a risky proposition, especially in todays market. Saving a few hundred dollars on an inspection could cost you litterally tens of thousands of dollars in the future. Keep in mind, most major mechanical componant only last about 15 to 20 years. Depending on the materials an asphalt shingle roof will typically last 17 to 30 years. Nearly everything inside a home has a life span and it's not as long as you would think. But the biggest problems we see are things being being done wrong. Whether it's done during a remodel or during new construction.
