There is moss on my north-facing slope. Is that bad?

Yes — moss holds moisture against the shingle and accelerates granule loss. We treat with a zinc strip at the ridge that releases small amounts of zinc with each rain, killing moss before it takes hold. Affordable add-on at replacement time.

My roof is 22 years old and looks fine. Should I wait?

Probably not. Once a roof is over 20, you are inside the failure window. The first failure usually shows as a leak, and by then you have interior damage too. A free inspection will tell you whether you have 1 year or 5.

Littleton Roofing Truth Center

Roofing in Littleton, Arapahoe/Jefferson/Douglas County

Littleton's Historic Downtown is one of the most well-preserved in the metro. The surrounding neighborhoods — Columbine, Ken Caryl, Centennial — run older housing stock with original or once-replaced roofs that are overdue. Large tree canopies create moss and algae conditions and drop debris that clogs gutters and traps moisture. Littleton homeowners tend to be long-term residents who prioritize quality over price.

Before you call any roofer

Take wide-angle photos of your roof and gutters from the ground, dated.
Check your insurance policy's deductible and storm-damage timeline (usually 1 year in Colorado).
Get at least two written estimates — and walk away from anyone who pressures a same-day signature.
Verify the roofer carries general liability AND workers' comp insurance in Colorado.
Confirm the manufacturer warranty transfers with the home — most do, but ask in writing.
