Hail damage on asphalt shingles appears as dark, circular bruising or divots where granules have been knocked away — often compared to a ball-peen hammer strike. Missing granules expose the underlying asphalt to UV degradation. In St. Olaf, any hail event over 1 inch warrants a professional inspection. We provide written damage assessments for Clayton County homeowners.

Most standard residential roof replacements complete in one to two full working days. Larger or more complex roofs with multiple angles, steep pitch, or extensive decking repair can take three to four days.

The roof deck is the structural sheathing — typically plywood or OSB — that forms the surface the roofing materials are attached to. Deck condition is assessed during replacement and damaged sections are replaced before new materials are installed.

Curling is typically caused by moisture imbalance during manufacturing, improper installation, or advanced aging. Buckling is often caused by poor ventilation that allows moisture and heat to build up beneath the shingles.

The dark streaks commonly seen on asphalt roofs are caused by Gloeocapsa magma, an algae that feeds on the limestone filler in shingle granules. It's more common in humid climates and can be treated or prevented with algae-resistant shingles.

Yes. Moss retains moisture against the shingle surface, creating conditions that accelerate granule loss and binder degradation. Left untreated, moss can significantly shorten shingle service life, particularly in humid or shaded areas.

A drip edge is a metal flashing installed at the eaves and rakes of the roof to direct water away from the fascia and into the gutters. It's a code-required component on most new and replacement installations.

Walking on a roof requires proper footwear and technique to avoid damaging shingles and creating safety risks. Most homeowners should avoid roof access; a professional contractor or inspector can assess the roof safely.

Soffits are the underside finish panels of the eave overhang. They typically contain ventilation openings that allow intake air into the attic. Blocked or damaged soffits compromise the ventilation system that keeps roofing materials from degrading prematurely.

Fascia is the vertical board running along the lower edge of the roof at the eave. Gutters attach to it, and it protects the roof edge from moisture. Rotted or damaged fascia is often discovered during roofing inspections and may need to be replaced.

A valley is the V-shaped trough formed where two roof planes meet at a downward angle. Valleys channel concentrated water volume during rain events and are one of the highest-wear areas on any roof.

A ridge cap is the roofing material that covers the peak where two roof planes meet at the top. It must be properly installed with appropriate overlap and nailing to resist wind uplift at this exposed location.
