Our Roof Replacement & Installation Services in Belmont
Full Roof Replacement
Most Belmont homes built in the 1950s-1970s are carrying roofs well past their designed lifespan. Wood shakes installed in the 1970s and 1980s are still common on upper-hill properties, and they often hide deteriorated underlayment beneath a surface that looks passable from the street. We strip to the deck, inspect for rot, and install a complete assembly - underlayment, flashings, ventilation - with no substitutions. On hillside lots, we bring specialized staging equipment that protects your gutters and landscaping. A full replacement on a typical Belmont split-level runs $22,000-$38,000 for asphalt shingles, $35,000-$55,000 for metal.
New Construction Roofing
Belmont’s remaining infill lots - particularly the steep parcels west of El Camino Real - demand roofing crews who understand hillside engineering. We coordinate with framers and general contractors to get the water-shedding details right at complex valleys and multi-plane intersections before the walls go up. Getting it right during construction means no callbacks, no torn-off shingles in the first storm, and a roof that matches the 40-50 year lifespan of the structure.
Asphalt Shingle Installation
Asphalt shingles remain the practical choice for most Belmont homeowners, and we install GAF, CertainTeed, and Owens Corning lines with proper ridge venting and ice-and-water shield at valleys. For north-facing slopes that stay damp until noon, we specify algae-resistant granules and recommend biennial moss treatment - a maintenance rhythm we’ve learned from watching shingles fail early on the fog-trapped hillsides. A standard architectural shingle roof on a 2,500-square-foot Belmont home runs $18,000-$28,000.
Metal Roofing
Metal roofing is gaining ground on Belmont’s hillside homes, and for good reason. It sheds moss, carries Class A fire ratings without added underlayment, and lasts 50-plus years in the marine climate. Standing seam and stone-coated steel both perform well on the complex rooflines common to 1960s contemporaries. We install IKO metal products with proper fastening patterns for wind exposure on exposed ridges. Expect $35,000-$55,000 for a full metal replacement, with energy savings and insurance discounts that offset the premium over time.

Trusted Brands We Service in Belmont
We are authorized installers for GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - seven manufacturer lines, no substitutions. For Belmont homeowners, this means we stock the correct ridge caps, matching shingles, and proprietary underlayments locally. When a north-facing slope needs a repair or a detached workshop needs matching materials, we don’t order and hope. We pull from inventory and get it done. Most asphalt shingle repairs and partial replacements are completed in a single visit.
Common Roof Replacement & Installation Problems We See in Belmont Homes
- Moss crust hiding decay. North-facing roof planes on Belmont hillside split-levels can develop a thick, root-bearing moss crust within five to seven years of a new install. The fog re-wets those slopes before they fully dry, and the moss traps moisture against wood shakes, causing hidden decay beneath a surface that still looks passable from the driveway.
- Complex rooflines shedding water wrong. The asymmetric, multi-plane designs of 1950s-1970s hillside homes create valleys and flashings that inexperienced crews detail poorly. Water finds the gap, and the first sign is a stain on a cathedral ceiling that nobody noticed until it spread.
- Steep-lot access damaging property. Belmont’s sloped lots require specialized staging - pump jacks, scaffolding, or boom equipment - that crews from flatter cities often don’t carry. We’ve seen gutters torn off and landscaping crushed by contractors who treated a 30-degree slope like a suburban ranch in San Carlos.
- Fire-rated assemblies skipped on permits. Many hillside parcels in Belmont fall within San Mateo County fire hazard severity zones. Class A fire-rated roofing assemblies are a legal requirement on re-roof permits, not just a recommendation. We’ve been called in to correct jobs where a previous contractor installed standard three-tab shingles and the homeowner faced a stop-work order.

FAQs - Roof Replacement & Installation in Belmont
Belmont’s hillside geography traps marine fog on north- and west-facing slopes well into midday, keeping roof surfaces damp far longer than on the flatter Peninsula floor below. This sustained moisture drives aggressive moss, lichen, and algae colonization that breaks down asphalt shingles and wood shakes from the surface down. We specify algae-resistant shingles for these exposures and recommend biennial moss treatment as standard maintenance. Call (877) 367-1429 to schedule an inspection - estimates are free.
Yes, if your parcel falls within a San Mateo County fire hazard severity zone - which includes many hillside properties west of El Camino Real. Class A fire-rated roofing assemblies are a legal requirement on re-roof permits in these zones, not merely a recommendation. We verify your parcel’s status during our initial inspection and specify compliant materials from GAF, CertainTeed, or Owens Corning lines. Call (877) 367-1429 and we’ll confirm your requirements before you commit to anything.
Yes. We bring specialized staging equipment for Belmont’s sloped lots - pump jacks, scaffolding, and hillside-rated safety systems - and our crews are trained in steep-access protocols that protect your gutters, landscaping, and structures. We replaced a 1970s wood-shake roof on a north-facing split-level on Alameda de las Pulgas, finding a thick moss crust hiding rotted underlayment. We installed Class A fire-rated GAF Timberline shingles and reinforced the detached workshop door opener with a heavy-duty LiftMaster spring because the homeowner wanted one trip, done right. That’s how we work. Call (877) 367-1429.
Architectural asphalt shingles with algae-resistant granules are the practical choice for most Belmont split-levels, offering cost balance and performance in the marine climate. For homeowners planning to stay 20-plus years, metal roofing eliminates moss concerns entirely and carries a Class A fire rating without added underlayment. The complex valleys on these homes demand experienced crews who get the flashing details right - material matters less than installation quality on a multi-plane roof. We’ll walk your specific roofline and recommend what fits your timeline and budget. Call (877) 367-1429 for a free estimate.
We start with algae-resistant shingles, proper ridge ventilation to reduce surface moisture, and zinc or copper flashing at the ridge that creates a mild runoff barrier. Then we recommend biennial professional moss treatment - not pressure washing, which damages granules, but a targeted application timed before the fall rainy season. This maintenance rhythm is standard for upper-hill Belmont properties; local roofers who work these streets build it into their service plans because we know the biology of these exposures in a way that a contractor based in Foster City simply wouldn’t. Call (877) 367-1429 to set up a treatment schedule.
