roof repair
SAME-DAY

Roof Repair

After we fix your roof, we send you before-and-after photos and a written warranty. If it leaks again from the same spot within 5 years, we come back free. That's the deal.

storm damage repair
LICENSED

Storm Damage Repair

Storm damage claims in Maryland have a 1-year filing window with most carriers. Don't wait. We'll inspect your roof, document the damage, and help you file before the deadline. If there's no damage, we'll tell you that too.

new roof installation
TOP RATED

New Roof Installation

A new roof installation starts with getting the specs right. Roof pitch determines your material options. Attic space determines ventilation needs. Local code determines underlayment requirements. We handle all of that before the first shingle goes on.

metal roofing
GUARANTEED

Metal Roofing

Standing seam metal lasts 40-60 years with practically zero maintenance. Higher upfront cost than shingles, but you'll never replace it again. Our Gambrills metal crews do residential and commercial.

shingle roofing
INSURED

Shingle Roofing

We install asphalt shingles from every major manufacturer. GAF, Owens Corning, CertainTeed, Atlas, Tamko, Malarkey, IKO. Each has different warranty tiers and price points. We walk you through the comparison without pushing one brand.

flat roofing
FREE ESTIMATE

Flat Roofing

We repair and install flat roofs on Gambrills homes, garages, commercial buildings, and additions. TPO for reflectivity, EPDM for budget, PVC for chemical resistance near restaurants and kitchens.

commercial roofing
SAME-DAY

Commercial Roofing

TPO is our most-requested commercial membrane in Maryland. Reflective, energy-efficient, and it welds together at the seams for a watertight bond. We install 60-mil and 80-mil systems with 15-20 year manufacturer warranties.

gutter installation
LICENSED

Gutter Installation

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Gambrills). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

roof inspection
TOP RATED

Roof Inspection

Infrared moisture scanning available for Gambrills commercial and flat roof inspections. Thermal imaging locates trapped moisture in the insulation layer without cutting core samples. We use Flir E8 cameras to map wet areas, then core sample only the suspect zones to confirm. Saves time, reduces disruption, and gives you a precise repair scope instead of a guess.

emergency roof repair
GUARANTEED

Emergency Roof Repair

After we tarp and secure your roof, we document everything for insurance purposes. Photos, measurements, damage descriptions. Your adjuster gets a professional report, not a handwritten note.

skylight installation
INSURED

Skylight Installation

We install, replace, and repair skylights in Gambrills homes. Fogged glass, cracked frames, persistent leaks around old skylights. We fix it all. Sometimes replacing a 20-year-old skylight is cheaper than trying to repair it.

Simple Process

How It Works

1

Schedule Your Inspection

Our inspector walks the roof looking at shingle condition, flashing integrity, vent function, and signs of moisture underneath. 30-45 minutes for most Gambrills homes.

2

Written Estimate

We price by the roofing square with all materials itemized. You'll see exactly what you're getting. Shingle brand, underlayment type, ventilation specs, flashing details.

3

Expert Installation

Crew shows up on time with all materials pre-staged. Tarps go down, old roof comes off, new roof goes on. Most Gambrills homes are done in a single day.

4

Final Walkthrough

Before we leave: magnetic nail sweep across the entire yard, driveway, and walkways. Dump trailer hauled off. Gutters cleaned out. Your property looks better than when we arrived.

"Needed emergency tarping after a tree hit our roof. They were there in about 3 hours. On a Saturday. Tarped the whole section, removed the branch, and had a crew out Monday morning for the repair."

"I got a new metal roof. Standing seam in charcoal. Not cheap, but it looks like a completely different house. Their metal crew clearly knows what they're doing. Seams are dead straight."

FAQ

Frequently Asked Questions

You get two warranties: one from the manufacturer on the materials and one from us on the workmanship. As a GAF Master Elite contractor, we can offer the Golden Pledge. That's 25 years on workmanship plus 50 years on the shingle. Owens Corning and CertainTeed have similar programs. Our own workmanship warranty is in writing and covers installation defects.

First: put a bucket or container under the drip. If there's a visible bulge in the ceiling, carefully poke a small hole to let water drain into a bucket. This prevents the ceiling from collapsing. Then call (877) 586-1316. We do emergency tarping and temporary leak stops within 24 hours. The permanent repair follows once conditions allow.

There's no single "best" shingle. It depends on what you need. For warranty coverage, GAF Timberline HDZ with Golden Pledge is the best in the industry. For wind resistance, Owens Corning Duration with SureNail locks down tight. For value, CertainTeed Landmark or IKO Cambridge give you solid performance at a lower price point. We carry all of them.

Depends on size, pitch, and materials. Average in Gambrills is $12,000-$16,000 for a standard residential replacement with architectural shingles. We price by the square and itemize everything so you can compare to other quotes. Free estimates. Call (877) 586-1316.

Poor ventilation causes premature aging. If your attic runs hot in summer and your shingles are curling at 15 years, bad ventilation is probably why. Missing shingles cause water intrusion and accelerate everything. We do a free inspection and give you a straight answer: repair, plan for replacement in 2-3 years, or replace now.
