SO your feeling very good about that home your purchasing because a lot of the items are brand new like the roofing materials. This is where you need to be careful just because it's new doesn't mean it was installed correctly.I can't even count how many poorly installed roof's I have came across at a home inspection performed in the Houston Texas area. I have seen roof's at brand new homes and older homes where shingles were missing in areas,missing flashing, missing roof jacks, etc, but here's the one defects that really gets me nails not driven in all the way or nails that where driven all the way through the roofing material.
This is an example of poor workmanship this roof appeared to be less than five years old and is covered with nails penetrating through the face of the shingle leaving many areas where water can enter into the structure. There were also many areas where the nails were driven through the singles making the roof vulnerable to shingles blowing off roof during high winds. This all was easily prevented if the roofer would have adjusted the compressor properly and driven any nails down flush. I guess the roofer was just to lazy and didn't care about workmanship completing the job as fast as possible leaving a problem and expense for the home owner. Once again make sure your Houston area home inspector is performing quality inspections and not low quality like this roofer. If the roof area is not walked by your home inspector than more than likely this will not be visible from the ground area have Houston's edge home inspections LLC save you money from low quality roofing companies. Always remember just because it's newer doesn't mean it will last along time. If items are not installed correctly it will significantly limit the life of the product.
