Every Elytra Shield Roof Health Score is computed from the six factors below, with the exact weights shown. We publish our math because a score you can’t inspect is just an opinion — and because you should be able to check our work.
Age relative to the ~25-year practical service life of asphalt shingles. Newer scores higher; nothing ages a score faster than the calendar.
How much of the protective granule layer remains. Granule loss exposes the asphalt beneath to direct sun and rain.
Whether shingles retain the suppleness that keeps them watertight, or have dried toward brittleness.
Past leaks, patches, and repairs. A clean history scores higher.
Attic intake and exhaust. Poor ventilation cooks shingles from below and shortens their life.
Hail, wind, and severe-weather exposure the roof has absorbed.
Strong condition — preservation protects existing value.
Aging normally — a likely preservation candidate.
Meaningful wear — candidacy depends on the specific factors.
Serious wear — replacement planning is often the honest recommendation.
Published in full, because the verdict should never be a mystery — or a mood.
Score 78+ with roof age 18 years or less (strong candidate), or 62+ with age 22 or less (good candidate, confirmed on-site).
Score 45–61, or a higher score outside the age gates — a closer evaluation before any recommendation is made.
Score below 45. Preservation is not the right path — your report says so in writing, and we don’t sell roofs.
No photo, no score. Every factor we rate must cite an inspection photo from your roof — a score without evidence is an opinion, and we don’t sell opinions.
Our inspectors are never paid on treatment sales. Nobody at Elytra Shield earns more when your roof scores lower. The score has one job: being right.
You always get the whole score. Overall number, every factor, every photo, and the written verdict — nothing held back, nothing “internal.” Roof type adjusts the final number slightly (different materials age differently), and that adjustment is shown too.
Every assessment ends in one of three written verdicts — preserve, monitor, or replace — and if the honest answer is replace, that’s what your report will say.
A real example from our methodology: an 8-year-old roof scoring 82 — no leaks, no failures, nothing dramatic — re-scored at age 12 after normal weathering and one hail season: 67. Granules washed a little each season, flexibility faded as oils evaporated, and the calendar did the rest. Fifteen points, without a single “problem.” That’s why a roof never scores higher than it does today.
Version history — v1.1 (July 2026): published verdict thresholds, inspector-pay integrity rule, no-photo-no-score rule, full-disclosure rule, and the worked aging example, following adoption of the internal Roof Health Score Standard v1. · v1.0 (July 2026): initial publication — factors, weights, bands. If we change the rubric, the change and the reason will be listed here — that’s what publishing a standard means.
