It’s surprising how often I come across this issue when doing home inspections: metal flue pipes serving furnaces and water heaters that come in contact with roof sheathing and underlayment in the attic. When this occurs, it’s a very obvious safety issue.
This issue is especially common when roofs are replaced. Why? Contractors may neglect to appropriately cut back roofing materials during installation.
If you want to make sure your home doesn’t inspire David Byrne to write another song about burning structures, you’d be well-served to provide 1-inch of clearance, free and clear, around the flue pipe at all times. And again, this is especially important if you have had your roof recently replaced.
Tim Hance with All Islands Home Inspections shares a video of water intrusion in a crawl space from a recent home inspection. Water intrusion in crawl spaces is never okay, and should be dealt with by a qualified contractor as it can lead to structural issues and insect damage.
Tim Hance with All Islands Home Inspections shares a video of an uncapped chimney at a recent home inspection. In the past, chimney caps weren’t installed because people used their fireplaces all day/night as a source of heat; the constant updraft prevented water intrusion becoming an issue. Today, that’s not the case for most homeowners, so it’s really important to install chimney caps to prevent water intrusion that can lead to expensive damage. Thanks for watching!
Tim Hance discovered a “free-spinning” Jacuzzi tub faucet at a recent inspection on Orcas Island. If your faucet handle does this, typically the valve needs replacement; a plumbing contractor may very well advise simply replacing both faucets, especially if they’re older.
Tim Hance with All Islands Home Inspections discovers improperly installed roof coverings at a recent home inspection on Orcas Island. Without sufficient eave overlap, the underlying fascia trim, sheathing, and rafters are vulnerable to water and insect damage. Water and insect damage were presenting in many areas of this particular home. A qualified roofing contractor will likely advise the installation of a metal drip-edge flashing detail, installed under the roof coverings and overlapping the wood fascia board to help prevent water and insect damage; a roofing contractor may also want to improve the roof covering overlap/overhang as well.
Plumbing vent caps are installed during construction to pressure test the drain-waste-vent plumbing system before it’s filled with water and used regularly. Once the test is passed (e.g., the pipes hold pressure and don’t leak), these caps are supposed to be removed to ensure proper drainage within the home. This vent cap was discovered at a 1999 home on Orcas Island in the San Juan Islands. Surprisingly, I call this out all the time. If the vent has been abandoned, the cap is appropriate; but this usually isn’t the case. Usually, the plumbing contractor forgets to get back on the roof to remove caps. So, if you see caps, I’d remove them if the pipes aren’t abandoned.
Tim Hance with All Islands Home Inspections recently discovered unconventionally constructed trusses in a garage that have been cut at a home inspection on Orcas Island. Cutting trusses is expressly NOT ALLOWED as it can, and likely will, lead to structural settling and failure over time. In this case, the roof plane showed clear evidence of settling/sagging when viewed from the exterior; when I went inside, it was clear why the roof was settling. With an appropriate snow load, or with time, some of these trusses will likely crack and fail. In this particular situation, repair was difficult because the trusses were cut to accommodate large garage doors; the recommended interim solution was to install intermediate posts and beams, in the middle of the garage, to properly support the roof and allow for vehicle access and egress.
“Fogged” windows, or windows with condensation between glass panes, are commonly discovered at home inspections. From my perspective, it’s a cosmetic issue because the condensation between panes isn’t a water intrusion issue for the home’s health itself. Sure, you’ll lose some thermal efficiency when the window panes lose their seals, but it’s somewhat negligible in the grand scheme of things. In my experience, Realtors are about 50% successful in negotiating replacement of “fogged” windows in real estate transactions. The Seller typically takes the stance that the “fogged” windows were obvious when the offer was made. The Buyer, on the other hand, may take the position that (a) they didn’t notice the “fogged” windows or (b) they had no idea what it would cost to replace. If you have a significant number of fogged windows, replacement adds up quickly. Standard “fogged” windows typically cost $300-$500 each to replace; contractors can usually pop-out the old glass pane and install a new one, without having to encumber trim and siding elements. These pictures were taken at a recent home inspection on Orcas Island in the San Juan Islands.
