Architectural shingles
A layered profile creates a dimensional appearance. The selected product’s slope, fastening and accessory requirements still govern installation.

Shingle repair and replacement with the covering, flashing and protective layers planned together.
Shingles shed rain by overlapping down the slope. Starter, underlayment, edge protection and flashing handle the places where that pattern ends or changes. A new covering has to be installed with those details, rather than simply replacing the visible tabs.

An impact classification describes a product under a specified test. It does not make an installed roof hail-proof or settle insurance coverage or discounts.
Color changes the appearance of the whole roof. Profile and product selection also need to work with the roof’s slope, valleys, penetrations and ventilation.
A damaged section can be repaired when the replacement material fits and neighboring shingles can be worked without breaking. Widespread brittleness, damaged wood or repeated failures change the scope. A replacement removes the covering so the deck and new protective layers can be considered together.

No. A tested impact rating helps compare products under that test. Installation, the event and other roof components still affect the roof’s performance.
The city’s house-reroof FAQ requires complete tear-off and a single roofing layer. The permit guide explains that local requirement and links the city source.
