BOULDER – A thorough inspection of a home’s exterior is critical as conditions on the outside may also affect the integrity of the interior. Inspectors will make a visible inspection of the grounds around the house to see if rain water is draining away from the structure or towards it. Rain water that drains towards the house could damage the structure, weaken the foundation and allow water to get into the basement or crawl space.
Plants or trees growing too close to the house can damage the siding or roof covering; trees planted too close to the foundation may damage the foundation; untreated wood and ground contact can cause rot; overgrown landscaping can cause poor drainage and erosion.
Water draining towards the house instead of away from the house, can cause serious water damage. Gutter downspouts should have extensions to carry water away from the house. The amount of rain water coming off the roof could be in the thousands of gallons and if the water is discharged alongside the foundation, the inspector can recommend that homes with wet areas have sump pump systems
to remove water from under the house.
Roof leakage caused by old or damaged shingles/tiles or improper flashing is a common problem. It may be easy and inexpensive to repair damaged tile and shingles and to re-caulk the roof penetrations if found in the early stages. Some homes have class 3 or 4 impact resistant roofing which can save a good amount on insurance premiums. You or your inspector may have to get this information from the inspector as it may not be visible after installation. Determining the exact age of a roof in insurance premiums.
All these areas and more should be covered in any inspection of the exterior of a home. Your inspectors should be able to answer questions regarding any of them.
