Spring is the best time to assess your roof in Boise. Winter freeze-thaw cycles, snow load, and ice events do their cumulative damage between November and March. Spring lets you find that damage while repair costs are still modest, before summer heat compounds any moisture that got in during winter, and before the contractor scheduling crunch of late spring and summer makes getting work done more difficult.
From the ground
Walk the full perimeter of your home and look for the following before getting any closer to the roof:
Missing or displaced shingles are visible from the street on most homes if you walk to different vantage points. A shingle that was lifted by ice or wind and didn't reseal may appear to lie flat but have broken adhesion underneath -- if you see any shingle that looks slightly lifted at a corner or edge, that's worth flagging for a closer look.
Granule accumulation at downspout splash zones is one of the most informative ground-level indicators. Some granule loss during a Boise winter is normal, but significant accumulation -- especially if the roof is under 20 years old -- points to accelerated wear. Compare what you see to what was there in previous springs if you can.
Gutters that appear to be pulling away from the fascia or sagging in sections were likely stressed by ice weight during winter. This affects drainage and, in severe cases, the structural attachment of the gutter system. Reattachment is a straightforward repair that's worth catching before the first heavy spring rains.
From the attic
The attic tells you what the roof exterior doesn't -- whether water actually got in. On a dry day, take a flashlight into the attic and look for:
Water stains or wet areas on the underside of the roof decking. Fresh stains will be darker; older ones may be brown or yellowish and appear dry even though they indicate past intrusion. Either warrants investigation.
Wet, compressed, or discolored insulation. Insulation that absorbed water during winter may appear dry by spring but has lost its R-value. Heavy compression of batt insulation in one area without corresponding compression elsewhere points to past moisture.
Daylight visible through any gaps around penetrations, at the ridge, or at the eaves. Any daylight from inside the attic is a problem.
When to call a professional
If you found granule accumulation, stains, or any evidence of water entry, a professional inspection is the next step. Blue Goat Roofing provides free estimates throughout Boise, Meridian, Nampa, Star, and Eagle. Even if you found nothing concerning, a professional inspection every two to three years -- or annually for roofs over 15 years old -- catches the early signs of failure that ground-level assessment misses.
