Tim Hance of All Islands Home Inspections documents handyman DIY repairs to a roof from a recent home inspection. Noted were displaced shingles, recently repaired and failed which, because they were displaced, I was able to tell there wasn’t a necessary tar paper underlayment installed. If you plan to conduct DIY repairs on your roof, please follow the installation instructions found on every package of roof shingles! Better yet, hire a roofing contractor.
If your roof isn’t too steeply pitched and has material that won’t be damaged by walking on it, AND you are mentally and physically fit to do so, carefully inspect it in good weather. Look for broken or missing shingles, missing or damaged flashing and seals around vent pipes and chimneys and damage to boards along the eaves. Shingle damage up-slope will often cause water damage far downhill. Check the chimney cap and screen and look down the flues for obstructions or animal nests. If you can’t or don’t want to get on the roof, you might want to use a ladder around the perimeter. Pay close attention to valleys and flashings; these are the primary leak-generators. Some simple, easy fixes now can prevent thousands of dollars of water damage later.
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.
Colored granules on your roof coverings are what protect the roof coverings themselves from the elements. This is why it’s important to NOT pressure wash your roof as doing so can lead to granular loss and reduce the roof’s life expectancy. In fact, I’ve seen newer roofs completely destroyed by pressure washing (treatment with zinc granules is the most common way to keep moss off your roof). Pictured here is substantial granular loss and exposed underlying fiberglass underlayment. These roof coverings were in poor condition, clearly due for replacement. This was discovered at a recent home inspection on Orcas Island in the San Juan Islands.
At a recent home inspection in Friday Harbor on San Juan Island, I discovered a substantial amount of corrosion presenting at standing seam metal roof coverings. Of course, rust and corrosion will only worsen over time with exposure to the elements, so I advised further evaluation by a qualified roofing contractor to make necessary repairs. Fortunately, there was no evidence (yet) of water intrusion to the interior at the time of inspection, but this is another great reason that it’s important to annually inspect and maintain your roof, even a metal roof.
Handyman roof repairs and displaced, missing roofing shingles were noted at a recent home inspection on Orcas Island in the San Juan Islands. Exposed nails and handyman repairs along with missing shingles put this roof system at clear risk of water intrusion. Amazingly, no evidence of water intrusion was presenting at the time of inspection. In this case, I recommended further evaluation by a qualified roofing contractor to make necessary repairs.

Your roof can be the second most expensive home repair/replacement you face (the foundation being first). As with most things in life, an ounce of prevention is worth a pound of cure. Weather allowing, November & December is as good time to perform a roof checkup to help diagnose potential problems early. Arm yourself with The National Roofing Contractors Association’s (NRCA’s) roof checkup guide for homeowners. Also, the NRCA can help point you to a reliable roofer. Click here for details.
Roof Help.com says, “There can be many reasons for a leak. Leaks can be the result of poor roof system installation, mechanical damage such as dropped screwdrivers or knives, plugged roof drains, roofing material failure, HVAC problems; the list goes on. The source of a leak can be quite distant from where it actually shows up…Chasing a leak isn’t always as easy as it would appear to be. When trying to locate a leak, use the following guidelines to assist you.”
Your roof leaks. You want to try repairs. Climbing a roof is hazardous. We recommend you call a professional. But, if you just have to try to DYI, AND if it is a minor leak AND you are fairly handy, agile, coordinated AND fit enough to get on your roof AND the roof is not too steep here are some considerations. Roof pitch or slope is a measure of the incline of a roof. So what is too steep? That’s a decision for you to make on a roof with a pitch LESS than 6. A pitch or slope of 6 means that the roof rises 6″ for every 12″ inward towards the peak (written as 6/12). A roof slope of 6/12 is equal to a 26.5 degree angle. More than this is too dangerous for an amateur DON’T try it!! Your local full service hardware store should be able help you to decide if you should try to repair your own roof. They should be able to give you a step by step approach, an explanation of materials needed and techniques used. We still think the best bet is to call a professional. Proceed at your own risk.
