Fresh trusses, open sheathing and a builder asking when the roofer can start: that is the call we hear most. Metal Roofing in Bucks connects Mapleton builders and homeowners with independent local roofers who handle Roof Installation on new framing, additions, garages and sunrooms. Call once and get routed to a licensed and insured contractor who can plan dry-in around your framing and inspection dates.
There is nothing to tear off on a new build, but there is a lot more to coordinate. The sheathing has to pass a nailing inspection in many jurisdictions before anything covers it, the windows and siding crews are waiting on a dry box, and the electrician wants the attic closed in. When dry-in drags, exposed OSB swells at the seams and those edges can telegraph through finished shingles.
Additions bring a different headache. Where a new roof meets the existing house is the spot most likely to leak, often within the first winter. A garage roof that dies into a second-story wall needs step flashing woven behind the siding, a kickout flashing at the bottom and sometimes a cricket. Sunrooms and porches built at a low pitch sometimes fall below what shingles are rated for.
Expect the local roofer to ask about the plans, the pitch and the framer's timeline before giving a number. Roof Installation done right starts with the material matching the slope, the underlayment matched to the climate and a tie-in plan for any existing roof. The goal is a roof that gets installed once and is registered with the shingle maker properly from day one.
With a new build, a roofer who shows up on schedule and follows the install specs is worth more than a low number.
Most general contractors and construction lenders want a certificate of insurance on file before the roofer starts. The contractors we route you to are licensed and insured independent businesses. Request the certificate, confirm the license with your local office and check who is listed on the roofing permit or if it rides on the building permit.
Open sheathing is a countdown. Once you are on the line, the dispatcher connects you with a nearby contractor who does new-construction work, often for a site visit within days, depending on contractor availability. If the trusses are already set and weather is coming, the dispatcher will flag it so a quick underlayment dry-in can be discussed.
Expect a quote built from the roof plan, listing squares, pitch, valleys, underlayment, ice barrier, drip edge, starter, vents and penetrations. For additions, the tie-in is priced as its own line, since it includes cutting back and reworking part of the existing roof.
New-construction roofers bring roof jacks and planks for steep pitches, fall-protection anchors nailed into fresh trusses, coil nailers set for the shingle maker's nailing zone and a material lift or boom delivery to land bundles on the roof. For tie-ins, they also carry flat bars, hook blades and shears to open up the old roof cleanly.
These are the install details worth asking any contractor about before work starts.
Before underlayment goes on, the roofer should check the deck the framers left. Panels should be staggered, gapped about an eighth of an inch for expansion, supported with H-clips between trusses where required and nailed on the schedule the inspector expects. Missed nails and blowouts at the truss tops get fixed now, not after the shingles are down.
Asphalt shingles need at least a 2:12 pitch, and anything from 2:12 to 4:12 calls for doubled underlayment. Below 2:12, the roofer will usually point you toward a membrane such as modified bitumen or TPO, or a metal system rated for low slope. Getting this wrong on a porch or sunroom roof is a common source of slow leaks.
To tie an addition into an existing roof, the contractor cuts back the old shingles, weaves or laps new underlayment under the old, and runs ice and water shield across the joint. Where the new roof meets a wall, step flashing goes in course by course with a kickout at the bottom. Matching shingle color on an older roof is rarely perfect, so ask to see samples.
The order matters: drip edge at the eaves sits under the underlayment, while at the rakes it goes over. A factory starter strip with its sealant line along the eave keeps the first course from lifting, and running starter up the rakes helps in wind. These are small parts, but missing them is something the shingle maker can point to later.
Valleys can be open with exposed metal, closed-cut, or woven, and each shingle maker has its own rules. Closed-cut is the most common look on new homes. Open metal valleys move the most water and suit roofs where a big upper slope dumps into a smaller one. Woven valleys do not work with many thick laminated shingles.
Skylights go in with their own flashing kits or site-built curbs before shingling, not after. Plumbing vents, bath fan hoods and the furnace flue all need boots or flashing that match the pitch. The roofer should coordinate with the plumber and HVAC crew so nobody cuts a fresh hole through a finished roof.
This is the normal path from your call to a dried-in, finished Roof Installation.
Tell the dispatcher whether it is a new home, an addition, a garage or a sunroom, plus the pitch if you know it and where framing stands. That routes the call to a contractor who works new builds and tie-ins.
An independent roofer books a site visit, often within a few days, or reviews plans first if the framing is not up yet. They look at truss layout, sheathing, wall intersections and where the new roof meets the old.
You or your builder get a written quote based on the roof plan, with the tie-in, valleys and penetrations broken out. The roofer also gives a target dry-in date that fits the sheathing inspection.
After dry-in and shingling, walk the roof edges with the contractor, check the tie-in and wall flashing and confirm the roofing inspection passed. The contractor explains their workmanship terms and the manufacturer's coverage in writing.
These composite examples show what new-construction and addition calls tend to look like.
A builder had a custom home framed and sheathed, but the original roofer backed out a week before dry-in. Rain was forecast, and the windows and siding crews could not start until the box was closed. The independent contractor routed through the line got synthetic underlayment and drip edge down within days, then came back to shingle after the sheathing inspection passed.
A homeowner added an attached garage, and water kept showing up on the drywall where the garage roof met the two-story wall. The routed contractor pulled back the siding and found continuous L-flashing instead of step flashing, with no kickout at the bottom. The fix was individual step flashing, a kickout and a reinstalled siding course.
A sunroom addition had been framed at about a 1.5:12 pitch, and the plans called for shingles to match the house. The contractor explained that asphalt shingles are not rated below 2:12 and suggested a modified bitumen cap sheet in a matching color. The homeowner chose the membrane, and the roof has stayed dry where shingles would likely have failed.
These are composite examples of the kinds of calls we route, written to show how the process works. They are not individual customer reviews.
The best time is as soon as the deck is sheathed and inspected. Book the roofer when you order trusses, not after they are set. Even a quick underlayment dry-in protects the framing and lets windows, siding and interior trades keep moving while shingles get scheduled.
The contractor cuts back the existing shingles a few courses, laps new underlayment under the old, adds ice and water shield across the seam and weaves new shingles into the old field. Where the addition meets a wall, step flashing goes in with a kickout at the bottom. Ask how they plan to handle color match on older shingles.
Most asphalt shingles are rated for 2:12 and steeper, and from 2:12 to 4:12 the underlayment has to be doubled. Below 2:12, plan on a low-slope membrane like modified bitumen or TPO, or a metal panel rated for that slope. Check the pitch before framing if you can, since raising it later is costly.
Yes. Each manufacturer publishes install instructions covering nailing zone, nail count, underlayment, starter, ventilation and approved valley methods. Many also offer extended coverage only when their matching accessory components are used. Ask the contractor which product line they install and whether they will handle the registration paperwork.
Independent roofers who do new construction are used to working around other trades. Share the build schedule up front. They will coordinate material drops, dry-in dates and penetrations with the plumber, electrician and HVAC installer so nothing has to be cut through finished shingles later.
Weathered shingles rarely match brand-new ones. Bring the contractor any leftover bundles or labels from the original roof. On a separate garage or a rear addition, a close match is often fine. If it bothers you, ask about matching the roof plane that is most visible from the street.
