Roofing built for the desert.

Downspout outlets, and the ground below them after a storm.

Shingles can shed granules as they weather. Wind-blown sand adds abrasion in the Coachella Valley, particularly along the San Gorgonio Pass corridor. An inspection checks whether the surface is wearing normally or exposing damaged shingles.

Flat and low-slope roofs, usually near a drain or behind a parapet.

Dust and sand can obstruct drains and scuppers. Low spots can also retain water even when outlets are clear. Check drainage and the roof surface before assuming a fresh coating will correct the problem.

Ridges, hips, and the first two courses above an eave or a rake.

Displaced tiles can expose underlayment and interrupt drainage. Wind requirements vary by site; Riverside County identifies several valley communities in a special wind region. Tile fastening, ridge details and edge conditions need an on-site assessment.

The middle of the field, and anywhere the sun lands longest.

The coating shields SPF from UV and weather. Thinning or exposed foam warrants an inspection of the coating, underlying foam and roof details. Recoating is appropriate only where the existing roof is suitable for it.

Ceilings, and the inside corners of exterior walls.

Summer thunderstorms can bring wind-driven rain to roof details that remain dry during lighter weather. Seasonal homes may hide the damage until an owner returns. Locate the entry point rather than treating the ceiling stain as the source.

Usually a valley, a penetration, or a flashing that has been sealed before.

A recurring leak may involve flashing, drainage or deteriorated underlayment beneath otherwise intact tile. The next assessment should establish why the earlier repair did not hold before another surface patch is proposed.
