Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

  1. 2)Lowest row of shingles loses tab adhesion early - The bottom edge of the first row of shingles provides an exposed place for the wind to catch and lift, and these shingles tend to loosen first. This means that the bottom row is also more likely to have damaged, broken shingles. Also,
    pressure washing the facia and gutters of a home will pop the tab
    adhesion of  the first row of shingles. Think of a pressure washer head as a “hand-held hurricane.”

  2. 3)Corroded or missing drip edge flashing - The metal drip edge flashing provides a sharp and angled edge for the water to drip off. Without it, some rainwater will tend to run backwards under the roofing.

  3. 4)Tree branches rubbing - Leaves rustling in a gentle breeze in your backyard is pleasant sound, unless some of them are on branches that are rubbing against the surface of the roof shingles. The brushing action removes the granules that protect the roof surface. This occurs most often near the edge of a roof.

  4. 5)Antennas - Cable companies require their customers to sign a waiver before they will bolt a satellite dish on the roof—and it’s usually near the edge—for a reason: the bolt penetrations leak.

  5. 6)Ice dams - While not a problem in our area, ice dams near the edge of a roof are a common source of leaks in colder climates. The melting ice at the bottom of the mass backs up under the shingles. To learn how prevent them, we suggest reading the blog post of a home inspector in the winter wonderland of Minnesota, Reuben Saltzman:

   To recognize when it’s time to replace your roof, go to our blog: How can I tell if the house needs a new roof?

   If you want to understand the difference between an “architectural” and a regular shingle roof, see our blog: What's the difference between an "architectural" and a regular shingle roof?

   To figure out why your roof is leaking, go to our blog: Why is my roof leaking?

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country. It is possible that important issues related to your area may not be covered here.
