Valley Stream's Housing Stock and Roof Characteristics
Valley Stream's development happened in three major waves, each producing distinct housing types with different roofing needs:
Pre-war colonials and Tudors (1920s-1940s). The Gibson, Hungry Harbor, and North Woodmere-adjacent sections contain Valley Stream's oldest homes. These Dutch colonials and Tudor-style houses have steep roof pitches (8/12 to 12/12), complex valley intersections, and often slate or early asphalt roofs. Many have been re-roofed multiple times. At 80-100 years old, some still have original wood skip sheathing underneath that needs evaluation during tear-off.
Post-war capes and ranches (1948-1960). The bulk of Valley Stream's housing — neighborhoods along Rockaway Avenue, Corona Avenue, and the blocks surrounding Valley Stream State Park — consists of cape cods and ranches built during the same suburban boom that produced Levittown. Standard 1,200-1,600 sqft footprints with simple rooflines. Many of these are now on their second or third roof.
Split-levels and raised ranches (1960s-1975). North Valley Stream and the areas east of the Southern State Parkway contain split-level and raised ranch homes with slightly more complex rooflines. These were built with the then-standard 3-tab shingles and plywood sheathing. Most are now at or past the end of their second roofing cycle.
Tree canopy and debris impact. Valley Stream has one of the densest mature tree canopies in Nassau County, particularly around Valley Stream State Park and the Hungry Harbor section. Large oaks, maples, and elms deposit leaves and branches that accumulate in valleys and behind dormers, creating conditions for moisture retention, moss growth, and accelerated granule loss. We recommend regular gutter cleaning and moss treatment to extend roof life in these heavily shaded neighborhoods.
Storm vulnerability. Valley Stream's position along the Southern State corridor and its relatively flat terrain make it vulnerable to wind damage during nor'easters. The village also experiences periodic flooding in low-lying areas near Hook Creek, which can drive moisture up through eaves and fascia if proper ice and water shield is not installed.
Valley Stream Permits and Building Codes
Valley Stream's permitting depends on which section you live in:
Village of Valley Stream. The incorporated village maintains its own building department. Roofing permits are required for full replacements. The village building department turnaround is typically 5-8 business days. The village requires contractor licensing verification and proof of workers compensation insurance.
North Valley Stream / unincorporated areas. Areas outside the incorporated village fall under the Town of Hempstead building department. Permit requirements are similar but the application process and turnaround (7-14 business days) differ.
Nassau County requirements. All roofing contractors working in Valley Stream must hold a valid Nassau County Home Improvement Contractor (HIC) license. Our license number is on every estimate and contract. We carry $2M general liability and workers compensation on every crew member.
We handle all permitting and inspections regardless of which jurisdiction your property falls in. No extra charge.

Reviews
Review 1: "The big storm in January ripped shingles right off our steep Tudor roof. Tom's crew had a tarp on it the same afternoon and did the full repair by Thursday. They also spotted two other areas that were about to fail and fixed those too. Fair price, no drama." — Mike T., Valley Stream · Emergency repair + GAF HDZ · 2025
Valley Stream Roofing — Common Questions
schema: FAQPage
Q: How much does a new roof cost in Valley Stream, NY? A: For a standard Valley Stream cape or ranch (1,200-1,600 sqft), a full roof replacement with architectural shingles runs $10,500-$14,500. Larger colonials (2,000-2,500 sqft) with steep pitches run $16,000-$22,000. Two-layer tear-offs add $1,500-$3,500. Storm damage repairs range from $800-$5,000 depending on extent.
Q: What roofing company serves Valley Stream, NY? A: LI Roofing Co. is a GAF Master Elite certified roofing contractor serving Valley Stream and all of southwestern Nassau County. We have completed 35+ jobs in Valley Stream since 2014. Our Melville base is about 25 minutes from most Valley Stream addresses.
Q: Do I need a permit for a roof replacement in Valley Stream? A: Yes. If you are in the incorporated Village of Valley Stream, you need a permit from the village building department (5-8 business day turnaround). If you are in unincorporated North Valley Stream, you need a permit from the Town of Hempstead (7-14 days). We handle all permitting and inspections at no extra charge.
Q: How does the tree canopy affect roofs in Valley Stream? A: Valley Stream's dense tree cover — especially near the state park and in the Hungry Harbor section — deposits leaves, branches, and organic debris on roofs. This debris retains moisture in valleys and behind dormers, promoting moss and algae growth that degrades shingles prematurely. We recommend annual gutter cleaning, periodic roof debris removal, and algae-resistant shingles (GAF HDZ with StainGuard Plus) for heavily shaded Valley Stream properties.
Q: Do you handle storm damage repairs in Valley Stream? A: Yes. We respond to emergency calls 24/7 and can typically get a tarp on a damaged roof the same day. We document all damage with photos and detailed scope for your insurance company, handle Xactimate paperwork, and work directly with your adjuster. We have completed dozens of insurance roofing jobs in Valley Stream following nor'easters and summer storms.
Q: What is the best roofing material for Valley Stream homes? A: For most Valley Stream homes, GAF Timberline HDZ architectural shingles are the ideal balance of durability, wind resistance, and value. For steep pre-war colonials, we sometimes recommend premium designer shingles that complement the architecture. For heavily shaded properties, algae-resistant options are important. Metal standing seam is the premium long-term choice for homeowners planning to stay 20+ years.
Q: How do I know if my Valley Stream roof needs replacement? A: Key signs: granule accumulation in gutters, curled or cracked shingles visible from the ground, dark streaks (algae), moss growth, daylight visible in the attic, ceiling stains after rain, or shingles missing after storms. If your Valley Stream home was built in the 1950s-60s and the roof was last replaced 20+ years ago, it is likely at or past end-of-life. We offer free inspections — call or text us a photo.
