One of the older cities in the country, and it is built like it: brick rows, shared walls, and rear additions that were added a century after the front.
What Lancaster roofs are dealing with
On a row, the roof is one continuous plane crossing several properties, and the flashing at the party wall is the most common way water gets in.
North of the city the housing opens out into detached stock from the fifties onward, with shallow pitches and attics insulated long after they were framed.
Brick rows and twins in the city, where the roof is a continuous plane crossing several owners and the party wall rises through it. North of the city it opens out into detached stock from the fifties onward: shallow pitches, modest overhangs, and attics insulated decades after they were framed.
Not sure how much life is left up there? The roof age check walks the envelope part by part — which matters more here than a single number, because on metal the panel and the things holding it down age on different clocks.
Covering Lititz, Columbia, Ephrata and the rest of Lancaster.
- 1 The ridge cap. On metal it is a separate piece with closures under it. Blown snow finds the joint that was never closed.
- 2 The seams. A standing-seam roof lives at its seams and clips, not at its surface. The panel outlasts what holds it.
- 3 The valley. One channel taking what two slopes shed — and on the north side, holding snow long after the field is clear.
- 4 Where the ell meets the wall. A lower wing dying into the main house. Two roofs, one wall, and nobody sure whose seam it is.
- 5 The fasteners. Exposed screws through the panel, each with a rubber washer. The washers age; the screws work loose.
- 6 The eave. Drip edge, gutter, and the question every metal roof asks: where does a slab of snow go when it lets go?
When the work happens in Lancaster
Work runs from spring into late autumn, and on attached housing the street is an extra constraint. Container placement and protection for the neighbours on both sides have to be arranged, and in the denser wards that means a date rather than simply a van arriving.
What moves the price in Lancaster
On a row, the party wall flashing decides it — rebuilt metal outlives the covering, sealant does not, and the two prices are far apart. On the detached side it is the edge detail and the ventilation, because that is what produces ice every February and what a proper job corrects rather than covers.
On housing this old the price is settled underneath rather than on top. Five questions get there faster than comparing product brands, and if two or three quotes are already in hand, the quote comparison checklist puts them side by side:
- What is on the roof now, and does all of it have to come off?
- Is the sheathing solid, or spaced boards that need a new surface first?
- What is the per-sheet rate for decking, agreed before the roof is opened?
- Is the back wing specified separately from the front slope?
- Where does the snow go when it lets go, and what sits under that eave?
The work
Before you call anyone in Lancaster
A few questions come up on nearly every property in this valley, and the answers do not change from one borough to the next, so they are written once, in the guides — written for a market where the covering is as likely to be metal as shingle:
Why roofs struggle here
Six failures account for most of what gets reported in these three counties, and each one has its own page. Where a stain shows up inside is rarely below where the water came in.
