New Roof Systems for Lancaster Builds and Additions
Nothing on a new roof gets inspected again once it is covered. The drip edge, the ice membrane, the way the valley was set, the ventilation path through the soffit, all of it disappears under the finish within a day, and whoever owns the house lives with those decisions for the next quarter century. That is as true for an addition on an old Lancaster twin as it is for a house going up in East Hempfield.
This is roof installation as our Lancaster, PA office does it — the same crew, the same number, the same written estimate before anything starts.
Installation covers the whole assembly, not the part visible from the sidewalk. On a new house in Manheim or East Hempfield township, that means sheathing checked for fastening and spacing, drip edge, eave and valley membrane, underlayment, starter, field and ridge, in the sequence the manufacturer specification requires. On an addition to an older city home it means opening the existing roof at the tie-in rather than lapping over it. On a shop or equipment building it usually means metal over solid framing, with the ventilation path worked out before the first panel is set.
Two details decide whether a new roof lasts: what holds it down, and where the air goes. Fasteners have to land in the nailing zone and reach solid decking, which is a different calculation on fresh sheathing than on the old board decks common across the county. Drip edge goes under the underlayment at the eave and over it at the rake, so water is directed out rather than behind. Ventilation is designed as intake and exhaust together, with baffles at the eave holding insulation clear so the soffit path is not blocked the day the insulator arrives.
Builders get a scope that names the flashing, not just the shingle. Homeowners get the same free consultation, itemized estimate and written proposal, a start date we hold to, and a walkthrough with a magnet sweep and warranty documents at the end. Where we push back is on a plan that puts shingles on a slope too shallow to take them, and on any request to close in a roof before we have looked at the deck and the intake path. A warranty is only as good as the assembly beneath it, and an installation outside specification will not be honored.
Why Lancaster roofs are different
Building around Lancaster happens in two very different places at once. The corridors along Route 30 and Route 283 through Manheim and East Hempfield townships keep adding houses on open ground, where a long unbroken roof plane meets weather with nothing upwind of it. In the city and the older boroughs, most of the work is additions and rear ells squeezed between existing walls, tied into roofs framed a century ago. The same crew handles both, but not the same way.

Roof Installation in Lancaster
Roof Installation in Lancaster — common questions
Can you work to a builder's schedule?
Yes. We work from the framing plan and pitch, schedule against your dry-in date, and coordinate with the other trades so the roof is not what holds up interior work. The written proposal states what is included down to the flashing, which is where scopes usually disagree later. If the framing slips a week, tell us early and we will move rather than showing up to a roof that is not ready.
My addition has a cathedral ceiling. How does that get vented?
Not with a ridge vent alone. A ceiling with no attic above it needs a continuous air path from the eave to the ridge in every rafter bay, which means baffles installed against the sheathing and insulation held back from it. The alternative is a sealed assembly designed as such from the start. Either way the decision is made while the framing is open, because there is no convincing way to correct it afterwards.
Can you install a roof on a new shop or equipment building?
Yes, and metal is usually the sensible answer on that kind of structure. We set the panels, closures, ridge and eave details for the building rather than adapting a house detail to it, and we plan where condensation will go, since an unheated building with a cold panel above it can drip without a single leak. Standing seam and exposed-fastener options both work depending on the span and the budget.
Who handles permits and inspections?
Requirements come from the municipality, not from us, and we work to whatever your township or borough calls for. Tell us early if you are pulling permits so the paperwork lines up with the build schedule rather than pausing it. On new construction we can also provide certificates of insurance directly to your builder or lender before anyone gets on the roof.
How early should the roofer be involved in a build?
Earlier than most people call. The ventilation path, the valley method, the tie-in at an addition and any low-slope section all get easier and cheaper to resolve while the framing is still open and nothing is insulated. A five-minute conversation at framing stage regularly saves a change order later. Call the Grant Street office on (717) 912-9051 when the roof lines are drawn, not when the sheathing is going on.
