Now that we have finally had our first appreciable snowfall in the Rochester MN area we have to be on the lookout for Ice Dams. Ice dams are the result of snow melting on the roof due to poor insulation.
The electrical service drop is the point where the electrical service wiring enters the home. At this home inspection there was a rather lengthy span between the electrical pole and the service mast.
It’s Summer, and if you haven’t noticed yet, we have had a few storms. Once a storm has passed and it is safe to go outside, make a careful inspection of the exterior of your home and repair any minor damage that may have occurred.
As stated in the video, we had over 40 inches of snow here in Rochester during the month of December. Then to top it off we had above freezing weather and rain. This resulted in ice daming on most all homes in the area.
We had a lot of snow this past winter and apparently the load exceeded the design specifications of this garage roof. Or maybe deferred maintenance caught up with structure. Whatever the case, it appears this garage is near the end of it's useful life ;-).
Your home inspector saw this as I was passing by and couldn't resist stopping and taking a picture.
Ice dams can be a problem this time of year here in the Rochester MN area. Snow melts on the roof and freezes at the eaves leaving a dam. Continued melting will pool up behind the dam and has the potential to seep under your shingles, resulting in water damage to both the roof deck, as well as the walls and ceilings.
Sometime it doesn't hurt to maybe take a look at the roof after a storm. This might also explain the stain on the bedroom ceiling.
Here is a good example of a flat rubber roof that is part of an addition to a home. It was raining while I performed this inspection so I was able to see that there was a low area in the center of this roof.
It's coming up on Fall, and if you need a new roof on your home, now is the time to have one installed. Before you start, there are a few things you should know.
Climate changes in Southeast MN can cause gutters to pull away and leave gaps between the fascia board and gutter which will result in leakage and potential water damage. Leaking will allow roof water to accumulate near the foundation, and/or cause erosion issues.
Depending on their condition, old flashings can be reused when a roof is re-shingled. Your roofing contractor will be able to determine what is the best optionon whether to reuse or replace.
On this home inspection the sellers had disclosed that they had had a leak the previous winter and that the problem had been fixed by removing an ice dam and sealing at the roof to wall intersection.
Your doorbell rings and you aren't expecting company. You go to the door and there stands a salesman or contractor. It's that time of year here in the Rochester and Southeastern MN area where the roofing contractors show up after a storm, and the driveway sealers want to give you a deal on your driveway.
If your home has light colored shingles, you may notice black streaking, especially on the north facing side. In areas where there is less sunlight, you will tend to have more dampness. With dampness comes mildew and fungus growth. The best way to prevent mildew and fungus growth is to provide as much ventilation and sunlight as possible. Of course, this is easier said than done in some cases. Try to keep branches trimmed back on trees so that there is as much sunlight on the roof as possible.
There is no quick fix to mildew and fungus short of replacing the roof. I highly recommend that you hire a professional for cleaning your roof. Another option is to check with your local Rochester, or Southeastern MN building supply or hardware store for products that are designed to remove mildew. Make sure you follow all safety and health precautions when using any chemicals to treat a roof. Mildew removal products may affect paint, gutters, and plants, so again, make sure you follow all safety and application instructions.
Another product, which I have installed on my roof, is called Shingle Shield. This product consists of zinc strips that are placed under the edge of the shingles near the peak of the roof. Rain reacts with the zinc to create a chemical that will prevent the growth of mildew and fungus on your roof. Ever notice how white shingles remain white below metal roof flashings? Same concept with the zinc strips. Again, you should consult a professional roofer for installation of this product. It must be noted, that the zinc strips may not remove existing mildew and fungus. You may have to have your roof treated to remove existing mildew and fungus prior to installing the zinc strips.
If you are planning on replacing the roof on your home, you can also look into shingles that have mildew resistant chemicals built right into them. Or have the zinc strips installed with the new roof.
I usually discuss with my clients the importance of yearly roof maintenance. It's better to proactively identify and deal with potential problems before they become widespread. In many cases, if a problem is identified early and properly repaired, the extent and cost of the repairs will be significantly less than if problems were unattended.
