Diamond in the Sky Roofing is a licensed, bonded and insured roofing contractor based in San Marcos. Owner Duane Sibley has worked in roofing since 2015 and founded the company in 2020 to serve homeowners and businesses across San Diego County.
Wherever you are in the county, you get the same thing: a free inspection with photos, a clear written estimate, and the owner on the job. Call or text 760-410-2340. We offer 24/7 emergency service.

San Marcos (our home base), Escondido, Vista, Oceanside, Poway, Rancho Bernardo and 4S Ranch. Common work here: tile underlayment replacement, leak repair, full re-roofs and Class A fire-rated roofing for homes near open space.

Carlsbad, Encinitas, Solana Beach, Del Mar and Rancho Santa Fe. Salt air corrodes flashing and fasteners, so we focus on corrosion-resistant materials and careful flashing around skylights, chimneys and roof edges.

We serve homes and businesses throughout San Diego County, including the City of San Diego: residential tile, shingle and flat roofs, commercial low-slope roofs, skylights, and solar panel removal and reinstall during re-roofs.

We repair all types of roof damage on homes and commercial buildings, including leaks, cracked or slipped tiles, missing shingles, failed flashing and storm damage. Every repair starts with finding the real source of the leak, and you get photos of what we found.

When a roof is past repair, we replace it with materials suited to San Diego sun, salt air and fire zones: concrete and clay tile, architectural shingles and flat-roof systems. We handle permits and inspections, and on tile roofs we can often reuse good tiles and replace only the underlayment.

Homeowners get options that fit their home and budget, from tile underlayment replacement and shingle re-roofs to skylight replacement and Class A fire-rated roofing. You always get a clear written estimate before work begins.

We repair, maintain and replace low-slope and flat roofs for offices, retail centers, warehouses, restaurants and HOAs across San Diego County.


Storm damage or an active leak? We offer 24/7 emergency service across San Diego County, including emergency tarping and temporary repairs to stop water fast, followed by a permanent repair once it is safe.
Call or text 760-410-2340 any time.
