New Roof Installation in Exton, Built to Manufacturer Spec
A roof warranty is not a document, it is a set of conditions. The material carries a manufacturer warranty only if the assembly beneath and around it was built the way the manufacturer specified, and on new construction that is decided in a single day by people the homeowner never meets. Around Exton, where whole neighborhoods go up on a schedule, those decisions get made fast and are covered up faster.
This is roof installation as our Exton, PA office does it — the same crew, the same number, the same written estimate before anything starts.
Installation means the whole system: sheathing checked and fastened, drip edge, membrane at eaves and valleys, underlayment, starter along eaves and rakes, field, hips and ridge, and a ventilation path that genuinely connects intake to exhaust. We install on new houses, on additions to existing homes around Exton and Lionville, and on major renovations where a roofline is being changed rather than recovered. Where a design includes a low-slope porch, bay or connector, that section takes a membrane system instead of shingles, quoted as part of the same job.
Specification is not a slogan, it is a list. Fastener count and placement for the wind rating, driven flush rather than overdriven through the mat. Underlayment lapped in the required direction and dimension. Valleys built by one approved method along their whole length rather than switched halfway. Attic ventilation sized to the space it serves, with intake and exhaust in balance instead of a ridge vent and no way for air to enter. Get any of these wrong and the material warranty has an exclusion waiting in it, which nobody discovers until they try to use it.
Builders and renovation clients get a written scope naming the flashing, the underlayment and the ventilation, so none of it quietly leaves the job when budgets tighten. Homeowners get a free consultation, an itemized estimate, a proposal with a start date, and a walkthrough at the end with a magnet sweep and the warranty paperwork. All Pro is licensed, bonded and insured, carrying PA #PA052821, and certificates of insurance go to your builder or lender on request. What we will not do is install over a deck we have not inspected, or vent a roof on paper only.
Why Exton roofs are different
Building around Exton happens in the gaps. Preserved farmland and open space limit where new construction can go, so much of it is infill along Route 100 toward Lionville, or additions and renovations on lots developed decades ago. Those two situations create different roofs. A new house on open ground near the Chester Valley meets wind with nothing in front of it, while an addition on a shaded street in Malvern or Downingtown has to tie into framing somebody else built and then live under the same trees.

Roof Installation in Exton — common questions
How do you coordinate with our general contractor?
We quote from the drawings, hold a slot against the dry-in date, and put the flashing and ventilation detail in the written scope so there is no dispute about who was supposed to install what. Certificates of insurance go across before we mobilize. We also flag anything in the design that will cause trouble later, such as a low-slope connector detailed as shingle, while it is still cheap to change.
What actually voids a manufacturer warranty?
Installation outside the published instructions, most commonly. Too few fasteners or nails placed outside the nailing zone, inadequate ventilation, laying new material over an existing roof, or substituting components the specification does not permit. None of these are visible once the roof is finished, which is exactly why they happen. We install to the instructions and hand over the documentation so the warranty is something you can actually rely on.
How much ventilation does a new roof need?
It is calculated from the attic floor area, then split between intake and exhaust, with intake at least equal to exhaust. The practical version: continuous soffit intake protected by baffles, and continuous ridge exhaust, sized rather than assumed. Mixing exhaust types on one attic can short-circuit the airflow so the ridge pulls from a gable vent instead of the eaves, which achieves nothing at all.
Can you roof a renovation where the roofline is changing?
Yes, and that is where flashing detail matters most. New planes meeting old walls, changed pitches, and a dormer or connector added to an existing house all create junctions that did not exist before. We work with the framer so the tie-ins are built to be flashed properly rather than fixed afterwards, and we set the ventilation path for the new geometry rather than the old one.
Can a new roof be installed in winter?
Yes, with adjustments that a good installer plans for. Shingle sealant strips will not activate in the cold on their own, so vulnerable courses, rakes, eaves and ridge caps get hand-sealed. Material is kept warm before it goes up, since cold shingles crack when handled. New construction in this county continues through winter routinely; the work simply takes more care and slightly longer.
