Spring
Look over winter changes
From the ground, note missing or shifted shingles, sagging lines, damaged flashing, debris, or new water marks indoors. If you notice possible damage, ask a qualified roofing professional to inspect it.
Michigan roof care
A smarter roof maintenance guide for Michigan homeowners.
Learn what to check on an asphalt-shingle roof through Michigan’s seasons, what a homeowner can safely notice from the ground, and when GoNano roof rejuvenation may be an option for a roof that qualifies.
A homeowner’s starting checklist
- Look for changes from a safe ground-level view.
- Check inside after heavy weather for new water marks.
- Keep gutters and downspouts flowing safely.
- Record roof age, past work and visible concerns.
- Ask a qualified roofing professional if problems appear.
Michigan roofs experience cold winters, snow, rain, warm summers, strong winds and occasional hail. In Southeast Michigan, seasonal freeze-thaw swings make it useful for homeowners to keep a simple asphalt-shingle roof maintenance routine. The climate figures below provide local planning context from official NOAA/NCEI normals for Lapeer.
For local context, NOAA/NCEI 1991–2020 normals for the Lapeer wastewater-treatment station report 148.3 days per year with minimum temperatures at or below freezing and 34.4 inches of annual snowfall. Source: NOAA/NCEI climate normals.
Seasonal asphalt-shingle maintenance
What to look for throughout the year.
Summer
Notice sun and surface wear
Fading, brittleness, curling edges, moss, algae, or repeated granules in gutters are helpful observations to share. They do not determine treatment eligibility by themselves.
Fall
Prepare drainage pathways
Keep gutters and downspouts clear when it can be done safely from the ground. Have a qualified maintenance professional handle steep, high, or difficult access areas.
Winter
Stay off snow- and ice-covered roofs
Watch for new interior stains, heavy ice buildup, or roofline changes from the ground. For roof access or concerns, contact a roofing professional.
A roof-preservation option for qualifying shingles
Roof rejuvenation adds another option to a roof-care plan.
GoNano Roof Rejuvenation is a single application of treatment for asphalt-shingle roofs that qualify. Michigan Nano Roofing, your local certified GoNano distributor, reviews the roof and offers a treatment quote when the existing shingles may be suitable.
For a roof that qualifies, GoNano treatment may add 10–15 years of useful life and may offer potential savings of up to 80–85% compared with replacement. GoNano is one application and does not require scheduled five-year reapplication. Potential added service life and project savings vary with roof condition, product system, and quote scope. Michigan Nano Roofing can explain the current warranty terms for each application.

A closer look at common questions
Read roof clues without guessing at the diagnosis.
Are granules in the gutter a problem?
Some granule loss occurs as asphalt shingles age. Repeated or heavy accumulation, exposed asphalt, bald patches, curling edges, or several symptoms together are useful details for a roofing professional to evaluate. A ground-level view cannot establish whether a roof is suitable for GoNano treatment.
What about algae, moss, or dark roof streaks?
Organic growth and discoloration may relate to shade, moisture retention, debris, roof orientation, and nearby trees. Avoid pressure washing shingles or applying an unapproved cleaner. Ask a qualified roofing professional what is safe for the specific shingle manufacturer and roof condition.
Could hail or wind change the next step?
After severe weather, look for visible changes from a safe location. If shingles are missing, lifted, or leaking, a conventional roof repair provider should inspect the roof. GoNano is a preservation treatment for shingles that qualify, not an emergency repair or storm-damage fix.
How does roof age fit into maintenance?
Roof age provides context, but installation quality, ventilation, prior repairs, shingle design, sun exposure, and weather also matter. Two roofs installed in the same year may be in different condition. Keep any installation records and tell the roofing professional what you have observed.
GoNano’s single application
A roof review can open another path.
Michigan Nano Roofing applies one treatment to existing asphalt shingles that qualify. It is not scheduled for five-year repeat application.
GoNano materials describe potential 10–15 years of additional useful life on qualifying roofs and up to 80–85% potential savings compared with replacement. Outcomes and cost depend on product system, roof condition, access, and the written quote.

Enter your measured roof area for an early cost comparison, then compare the actual written GoNano quote with the replacement quote for the same roof.
Michigan roof maintenance FAQs
Common asphalt-shingle care questions
How often should I check my asphalt-shingle roof in Michigan?
From the ground, look over the roof after seasonal changes and notable weather. Check for visible missing, lifted, curling, or damaged shingles, worn flashing, and interior water marks. A roofing professional can inspect steep or hard-to-access roofs safely.
Does a roof rejuvenation treatment replace roof maintenance?
GoNano roof rejuvenation is one treatment for qualifying asphalt-shingle roofs. It complements routine upkeep such as gutter cleaning, ventilation care, and timely conventional roof repairs.
Can GoNano prevent ice dams?
Ice dams are related to attic heat loss, insulation, ventilation, and roof drainage. GoNano treats qualifying shingles; attic heat loss and ventilation are handled as separate home-maintenance issues.
What should I do if I find missing shingles or a leak?
Have a roofing professional review active leaks, missing shingles, or significant damage. Michigan Nano Roofing focuses on GoNano treatment for asphalt-shingle roofs that qualify.
Can I inspect the roof myself?
Observe from a safe spot on the ground; a roofing professional can handle close inspection of steep, wet, icy, or fragile roofs.
