Roofing & Exterior
A roof installed by hand, backed by a lifetime workmanship warranty, transferable when you sell. Slate, synthetic slate, architectural shingle, and standing‑seam metal across Maryland, Pennsylvania, and Delaware.
Why Diamond Elite
We started Diamond Elite to build the contracting practice we wished had existed when we needed one ourselves. Four principles run every job, from the first call through the final walkthrough.
Maryland sees freeze‑thaw winters and the occasional hurricane remnant in the same season. The wrong shingle on a steep pitch shows it within a year. We specify by climate zone and roof geometry, not by what the supplier had on the truck.
Every job is led by a foreman who has worked with us for years. We don't broker labor. The person who tears off your roof is the person who installs your new one.
Your community has architectural standards. We pull the file, draft the request, and submit on your behalf. Most homes in Hunt Valley, Columbia, Westminster, and Frederick County require it; we treat it as part of the job.
Lifetime workmanship on every full replacement, transferable once. Manufacturer system warranties up to fifty years. Written, registered, and on file before the dumpster leaves your driveway.
What we install
Owens Corning Duration is our most‑installed system: a 30 to 50 year architectural shingle that disappears into the architecture. CertainTeed Landmark and GAF Timberline HDZ also available on request.
For the older inventory across Roland Park, Frederick, and Lancaster: real slate restoration, DaVinci synthetic systems engineered to match the original profile, and full cedar replacements with copper valleys.
Tighter panel widths, hidden fasteners, and 24‑gauge steel or copper for the contemporary builds going up across Ellicott City, Frederick County, and Howard County. Engineered for snow load and wind uplift to Maryland code.
Documentation, adjuster meetings, scope advocacy. We work the claim so you don't have to.
6‑inch K‑style and half‑round seamless aluminum or copper. LeafGuard & Gutter Helmet certified installs.
James Hardie, LP SmartSide, and PVC trim restoration as part of any full exterior project.
Velux factory‑certified installation, including solar‑powered fresh air models with 30% federal tax credit eligibility.
The number‑one source of leaks on older Maryland homes. We rebuild flashing in lead and copper, not aluminum.
Ridge vent, soffit intake, and powered options. We balance the system before sign‑off, not after.
How we work
One call or one form. We confirm a 90‑minute window on your property, usually within the same week.
Drone imagery, attic inspection, ventilation analysis, photographed deficiencies. You keep the full report whether or not you hire us.
Samples brought to your driveway, held side‑by‑side against your existing roofline. No upsell pressure. No surprise change orders.
We pull the architectural review packet, fill it out, and submit. Most Maryland HOAs respond within ten business days; we coordinate the back‑and‑forth so you don't.
Tarps over every shrub, magnetic sweeps morning and evening, dumpster placed off your drive when possible. A typical replacement takes one to two working days.
We register your manufacturer system warranty, file the workmanship warranty, and walk every elevation with you before invoicing.

What clients tell us
The crew showed up at 6:45 am, had tarps and plywood down on every shrub before they touched the roof, and were gone by Tuesday afternoon. Two days. The yard was cleaner than when they started.
I'd interviewed three roofers. The other two told me what I wanted to hear. Todd told me my flashing was the actual problem and the shingles had another seven years. He saved me an unnecessary roof replacement and earned the next one.
Jessica answered every question we had, in plain English, the same day. The project itself was excellent, but the communication is what we'll tell our neighbors about.

Common questions
Most full asphalt replacements take one to two working days. Slate, synthetic slate, and standing‑seam metal projects run three to five days depending on roof area and complexity. We always confirm in writing before starting.
If wind, hail, or fallen tree damage is documented, most homeowners' policies in Maryland, Pennsylvania, and Delaware cover it. We perform the HAAG‑certified inspection at no cost, prepare the photographic and Xactimate scope, and meet the adjuster on site to advocate for the correct scope. There is no charge unless work proceeds.
Yes. We pull the file, complete the architectural change request, prepare sample boards, and submit on your behalf. Most Maryland HOAs respond within ten business days; we coordinate the back‑and‑forth so you don't.
Architectural (also called dimensional) shingles are the modern default: two‑layer laminate, 25 to 30 year service life. Luxury‑tier shingles (Presidential, Grand Manor, Camelot II) are heavier, multi‑layer, and visually closer to slate or shake. We sample both side‑by‑side against your existing roofline before you decide.
Tarps and plywood over every shrub, planter, and AC unit. Magnetic sweeps morning and evening for stray nails. Dumpster placement coordinated to avoid driveway pressure cracking. We walk the perimeter with you before we leave.
Lifetime workmanship on full replacements, transferable once. Manufacturer system warranties from 30 to 50 years depending on system. All warranty documents are registered with the manufacturer and emailed to you within seven business days of completion.
Yes. We work with GreenSky and Service Finance. Most projects qualify for 0% APR for 18 months or extended low‑APR terms. We provide application links once a scope is finalized.
We never tear off more area than we can dry‑in by end of day. If weather moves in unexpectedly, we tarp and pause. Re‑tarping is at no cost, and we do not charge for weather delays.
Book a roof survey
Most surveys are scheduled within the same week. The visit takes about ninety minutes on your property and produces a written report. The report is yours to keep, whether or not you decide to work with us.
