Roof replacement

What a new roof
costs in the Lehigh Valley.

The number, what moves it, and what happens on your property once the crew shows up.

The short version. A roof is priced by size and shape, so there's no single number that means anything. A simple ranch and a steep colonial with four dormers are different jobs. Most roofs go on in one day, and you get a written number before anyone touches anything.

Cost

What a new roof costs.

A roof is priced by size and shape, so a single number on a website would not mean anything. A simple ranch and a steep colonial with four dormers are different jobs.

Material prices have been moving month to month, so rather than publish a range that goes stale, the number you get is measured for your roof and written down before anyone touches anything. The inspection is free and there is no obligation attached to it.

What moves the price

Six things, roughly in order of how much they matter.

Size
Measured in squares, where one square is 100 square feet. It's the biggest single factor and it's the first thing measured.
Pitch
A steep roof needs staging, harnesses and more time. The same square footage can cost noticeably more.
Layers coming off
Two or three old layers means more tear-off labor and more dumpster.
Decking condition
Rotten plywood only shows up once the old roof is off. It gets priced per sheet so there are no surprises.
Complexity
Valleys, dormers, skylights, chimneys and turrets all add flashing work, and flashing is where roofs leak.
Material
Architectural asphalt is the common choice. Metal, synthetic slate and cedar shake all price differently.

A quote that arrives without someone measuring the roof isn't a quote, it's a guess. Ours comes after the inspection, in writing, with the decking allowance stated up front.

The job

Most roofs go on in a day

Most residential roofs go on in a single day. The crew shows up early, the old roof comes off, the new system goes on, and the property gets cleaned before anyone leaves.

Bigger or steeper roofs run into a second day. You'll know which one yours is before we start, not halfway through.

Step by step

What happens on your property.

The walk-around

Someone gets on the roof, measures it, photographs it, and checks the attic where it matters. You get told what's wrong, including if the answer is a repair rather than a replacement.

Day 0

Written number

A written quote with the system spelled out, the decking allowance stated, and financing options if you want them. No pressure and no expiring discount.

Within 48 hours

Protection goes down

Landscaping, siding, windows and AC units get covered before a single shingle comes off.

Morning of

Tear-off

Everything comes off down to the decking. Rot gets found here, and you get shown it before it's replaced.

Morning

The system goes on

Leak barrier in the valleys and along the eaves, deck protection, starter strip, Timberline HDZ, ridge cap and ventilation. That's a full system, and the system is what the warranty covers.

Afternoon

Cleanup and final walk-through

Magnet rolled over the whole property for nails, debris hauled, and a walk-through with you before the crew leaves. Perfection is demanded from the walk-around to the final walk-through.

Same day

What goes on the roof

The full GAF system.

Being GAF Master Elite means the whole system can be installed and warranted as one thing, rather than shingles from one place and everything underneath from wherever.

Shingle
GAF Timberline HDZ architectural asphalt, with the StrikeZone nailing area for install accuracy
Underneath
GAF leak barrier at valleys and eaves, roof deck protection across the field
Finish
Starter strip, ridge cap and balanced ventilation
Warranty
Golden Pledge: 50 years non-prorated on material defects, 25 to 30 years on workmanship, tear-off and disposal included. Terms set by GAF and vary by system.
Wind
Unlimited wind speed coverage when installed with six nails and starter strip
Algae
25-year limited warranty against blue-green algae discoloration

Straight answers

Questions we get asked

Do I need a full replacement, or will a repair do?

If the damage is in one area and the rest of the roof has life left, repair it.

Replacement makes sense when the roof is near the end of its life, when there's damage across multiple slopes, or when there are already two layers up there. If a repair is the right answer we'll say so, because a repair that holds for six years is a better outcome than a roof you didn't need.

How long does a roof replacement take?

Most residential roofs are done in one day.

Crews typically start around 6:30am and are cleaned up by late afternoon. Larger homes, steep pitches and complicated rooflines run into a second day. Weather can move a start date, and we'd rather move it than install in the wet.

Do I have to be home?

No, though most people like to be there for the final walk-through.

The crew doesn't need access to the inside unless there's attic work involved, and you'll know that in advance.

What happens if you find rotten decking?

You get shown it, and it's priced per sheet at a rate agreed before the job starts.

Nobody can see under the old roof until it's off, so any honest quote has a decking allowance in it. What you should never get is a surprise number invented on the day.

Can I finance a new roof?

Yes, through the HEARTH payment program.

It spreads the cost into monthly payments and takes minutes to check. It's worth doing before you decide on materials, because the difference between good and better is often smaller per month than people expect.

What if the damage came from a storm?

Then this may be an insurance claim rather than an out-of-pocket job.

Hail and wind damage is usually covered, and you'd pay your deductible instead of the full cost. That's a different process with its own timeline. Here's how a roof claim works.
