Home Inspection Terminology: A Guide for Real Estate Agents!

At Alpine Building Performance, we’re excited to introduce our educational series (Part 1 and 2) designed to help real estate agents navigate the often complex terminology used in home inspections and residential construction. Whether you’re new to the industry or looking to deepen your expertise, this guide is here to clarify the essentials - and a few lesser-known terms. Let’s dive in!

Roofing Terminology

Starting at the top, here are some fundamental roofing terms to know:

• Roof Deck/Roof Sheathing: The structural base of the roof, typically made from plywood or oriented strand board (OSB), where roofing materials are applied.

• Underlayment: A moisture-resistant layer placed between the roof deck and shingles, made of felt or synthetic material.

• Flashing: Metal or other materials used to direct water away from roof joints, such as chimneys and vents, preventing leaks.

• Eaves: The overhanging edges of the roof that extend beyond the exterior walls.

• Ridge: The peak of the roof where two slopes meet.

• Soffit: The underside of the roof overhang, often ventilated to support attic airflow.

• Fascia: The vertical board along the roofline, where gutters are typically mounted.

Exterior Terminology

The exterior of a home is a major focus in inspections. Here are key terms every agent should know:

• EIFS (Exterior Insulation and Finish System): A multi-layered exterior cladding system offering insulation, waterproofing, and a decorative finish. Proper installation is crucial to avoid moisture issues.

• Capillary Break: An air gap between materials to prevent moisture wicking into building components, such as between siding and the ground.

• Brick/Stone Veneer: A facade that serves as siding rather than a structural wall. Unlike solid brick walls, veneers are primarily decorative.

• Pressboard Siding: Engineered wood siding made from compressed wood fibers, resin, and wax. While affordable, it’s prone to moisture damage without proper maintenance.

• Fiber Cement: A durable, moisture-resistant siding made from cement, sand, and cellulose fibers, often mimicking wood or stucco.

• Balcony vs. Deck: A balcony is accessed only from the interior and lacks stairs to the ground, while a deck is open and typically has exterior stairs.

• Flatwork: Refers to horizontal surfaces like concrete sidewalks, patios, or driveways.

• Weep Holes: Small openings in masonry or window frames that allow trapped moisture to escape, preventing structural damage.

How to determine if a roof has impact resistant (Class 4) shingles

Can you tell if the roof has “impact resistant class 4 shingles”? Our homeowners insurance wants to know..

This is a question that we get almost daily as home inspectors and it’s a frustrating question because there is no way to visually determine if a shingle is impact resistant/class 4 rated. The only way to determine a shingles impact rating is by the manufacturer's spec sheet. Some shingles do have labeling on the back side of the shingle, but of course we can’t see that without ripping up a shingle.

Tip: If a roof is newer or if you have the contractor's information who installed the shingles, then we recommend contacting the contractor to see if product specifications are still available for that job. Sometimes there are extra shingles lying around the property, but that is rare and not reliable. Most often the answer is just not available and certainly something that the inspector cannot determine through the normal scope of an inspection.

Other non asphalt shingle roofing materials such as concrete tile or metal roofs are inherently impact resistant and don’t need a rating to determine impact resistance.

Next time you are advising your clients on a homeowners insurance application or looking for this info yourself, keep this information in mind and see if you can track down documentation from when the roof was installed.

How Much Does A Standard Garage Door Tuneup Cost And What Does It Include?

A garage door and opener servicing generally costs between $120-$150, but many companies will run door service specials periodically for less than $100.  

Routine garage door and opener service typically includes a comprehensive inspection of panels, hinges, bearing, cables, drums, track and opener for any irregularities. This also typically includes re-tensioning the springs for proper balance as well as making any adjustments to the door to make things run as smoothly as possible. A garage door technician should also check the opener limits and sensitivity to ensure safe operation.

How often should a garage door be maintained and why is routine maintenance important?

Garage door professional, Louis Wilson, of Ascent Garage Doors recommends that garage doors should be serviced annually or at least every other year in order to maintain proper spring balance and make sure there isn’t any progressive failure of components that could cause larger problems. 

Many people don’t realize it, but a garage door is the largest moving part of a home and can present safety issues if not properly serviced. Regular service greatly reduces the risk of large problems with your door coming off track, getting stuck, or even panels falling, which is a huge safety hazard.
