Homeowners with a 20-year-old roof:

If you maintain your roof and keep your gutters cleaned then you should have no problems with your roof. However, when you have the original roof and you have not done anything to the roof but you notice a little something leaking in the house. You probably need to have it inspected. Most inspectors when seeing a roof of this age will tell you to replace it. Homeowners are better safe than sorry. You want too protect your most precious investment.

Homeowners selling a home:

It is important to go through a home inspection when you sell your home. Normally it is the purchaser responsibility to get a home inspection. When we come to the roof, it is just good business to tell the purchaser the last roofing issues you have with the home. If you have owned it and there has never been and issue, let them know that also. Nine times out of ten, We have seen new home owners say "I just bought this house and the warranty just ran out and the previous home owner did not mention any roofing issue".

Homeowners with a two layers Roof:

We have heard people in the industry say that, you can have 3 layers of shingles on a roof before you have to replace them. In fact, We have heard some people repair roof jobs in patch work just replacing a few shingles. This can be effective if the ply board under the roof is still in good condition. We have seen a roof with 3 layers of shingle (the third layer just recently placed) cave in because of the weight. The roof didn not simply fall in, but the roof sagged in an area allowing water to seep in through the ply boards causing damage to the board and drywall in the ceiling.

A roof is your home first layer of protection. It is best to care for your first layer of protection properly or you will have major challenges in the future.
