If repair after repair is not making sense anymore, a full tear-off and rebuild is usually cheaper over five years than another patch. We do asphalt, metal, and rubber from one local crew — most homes finish in one to three days, with a manufacturer lifetime warranty and financing if you want it.
A roof replacement is the largest single repair most York County homeowners ever pay for, and the wrong contractor can turn it into a headache that follows you for the next two decades. Cool Water Roofing has been replacing roofs across Hanover, Spring Grove, York, Dover, Glen Rock, and Red Lion since 2007. We are based in Spring Grove, PA — meaning the same crew that meets you for the estimate is the same crew that tears off your shingles, lays the new system down, and cleans up the driveway when it is done. No subcontractor handoff, no out-of-state sales rep, no surprises at the end.
If you have already had two or three repairs in the last few years, or your roof is nearing the 18-25 year mark on architectural shingles, this page is for you. Call (717) 823-6501 or use the form on the right and we will be at your house with a free in-person assessment, usually inside a week.
Most homeowners ask the wrong question. The right question is not "is my roof leaking?" — it is "is the underlying decking and felt still doing its job?" These are the signs we look for during the assessment, and the ones that usually push the math from repair to replace:
If you are not sure which side of that line you are on, start with a free roof inspection — we will tell you straight whether you can squeeze another five years out of it or whether replacement is the smarter spend.
The default choice on roughly nine out of ten York County homes. Modern architectural shingles carry a manufacturer-rated lifetime warranty, hold up to high winds along the I-83 corridor, and come in dozens of colors that look right against red brick, white siding, and stone. Most of our installs use GAF or Owens Corning systems, with the matching ridge cap, starter strip, and underlayment so the warranty actually transfers if you sell the house.
Metal lasts 40-50 years, sheds snow cleanly, and is the right call for low-slope additions, porch roofs, and detached structures. We install both standing-seam (concealed fasteners, premium look) and exposed-fastener panels (more affordable, very durable on outbuildings). Insurance carriers in PA increasingly favor metal because it does not lose granules in hail.
For low-slope sections that asphalt cannot drain — porch roofs, additions, and small commercial buildings — rubber membrane is the right answer. We hot-air weld the seams, run proper edge metal, and tie the rubber back into the steeper portion of the roof so the transition does not leak.
The honest answer: a complete tear-off is almost always the right call, and overlays only make sense in narrow situations. Here is the math we walk every homeowner through:
If you are getting quoted an overlay only because it is cheaper, ask the contractor what the warranty looks like and whether they would put their own roof under it. We almost always recommend tear-off — and we will tell you when the overlay actually does make sense (a one-layer roof, in great deck shape, on a budget).
Most architectural shingles ship with a "lifetime" warranty, but the warranty is only as good as the install. To get the full coverage on a GAF or Owens Corning system, the entire roof has to be installed with matching components — underlayment, ice-and-water shield, starter strip, ridge cap, and the right ventilation. We use the matched-component approach on every replacement so the warranty transfers cleanly to the next owner if you sell. We also stand behind our workmanship for ten years on top of the manufacturer warranty — if it leaks because of how we put it on, we come back and fix it on our dime.
We work with several outside lenders that specialize in roof replacement financing for York County homeowners. Approval and rates depend on credit and the lender, so we don't quote rates on a website — but plenty of our customers go that route, and we are happy to walk you through the application. The free in-person estimate has zero obligation either way: cash, financed, or insurance-claim, the price is the price, and you decide what works.
For a typical York County two-story with a single-layer asphalt roof, we are usually on and off the property in one to three working days. Larger or steeper homes, multi-layer tear-offs, or houses with significant deck rot can run a day or two longer. We pull permits, dump-truck the tear-off debris off your property the same day, and run a magnet through the lawn before we leave so the crew does not leave nails behind. Weather windows in spring and fall are the most predictable; summer storms occasionally push us a day, but we will not start a tear-off if the weather looks bad enough to expose the deck overnight.
The same things show up in nearly every Google review we receive: they showed up when they said they would, they cleaned up before they left, and the crew was polite to the family in the house. We are licensed in Pennsylvania (PA #PA18635), fully insured for liability and worker's comp, and we are the same Spring-Grove-based crew on every install — no rotating subcontractors. If you would like a current certificate of insurance before the job starts, we email it on request. To get on the schedule, call (717) 823-6501, or fill out the form and Brian or someone on the crew will be back in touch within one business day.
It depends on size, pitch, the number of layers being torn off, and the material you choose. After the in-person assessment we hand you an itemized written estimate — same-day or next-day — with a fixed price you can take to the bank. We do not quote ballpark numbers over the phone because every roof is different, and a phone quote always ends up being wrong.
For a typical York County two-story with a single-layer tear-off, we are usually on and off the job in one to three working days. Larger homes, steep pitches, multi-layer tear-offs, or significant deck rot can extend that by a day or two. Weather can also push the start date if a storm is coming — we will not strip a roof we cannot get back under cover the same day.
No. Once the estimate is signed and the materials are delivered, you can be at work or out of town and we will let ourselves on and off the property. We will keep you updated by text and call before any line item changes (for example, if we find unexpected deck rot under the old shingles).
We tarp the perimeter, set up plywood ramps and protection over flowerbeds and the AC condenser, and run a magnetic sweeper across the lawn and driveway before we leave. If we damage anything — gutters, fascia, a hosta in the wrong place — we make it right.
Yes. We work with outside lenders that specialize in roof replacement financing for PA homeowners. Approval and rates depend on the lender and your credit, so we do not publish rates on the website — but the application takes a few minutes and we are happy to walk you through it.
Yes, but the warranty depends on a matched-component install. To qualify for full coverage on systems like GAF or Owens Corning, the entire roof has to use matching shingles, underlayment, ice-and-water shield, starter strip, and ridge cap. We install that way on every replacement and we add a ten-year workmanship warranty on top of the manufacturer's coverage.
Yes — we install year-round in York County, including December and January, as long as the temperature, wind, and precipitation cooperate on the day of the install. Asphalt shingles need a minimum temperature to seal correctly, but we know the workarounds and we have replaced plenty of roofs in the cold months without compromising the warranty.
Yes. If a storm did the damage, we document what we see on the roof, sit in on the adjuster meeting when you want us there, and write the scope so it lines up with what the carrier will actually pay for. We do not charge extra for the claim help — it is part of the job.
"Brian and his team did an excellent job replacing our 20-year-old roof. His team worked hard on a bitter cold day in December and did a wonderful job cleaning up all of the debris."
"On time, very clean with drop cloths and other safety measures, and installed the roof during a period of high winds. Warranty, professionalism, and quality workmanship, from the free quote until completion, was outstanding."
"Derrick and his crew did a great job. They came recommended and didn't disappoint. Did my roof and gutters, took great care of my place, great communication, and excellent work."
Free in-person assessment, written itemized estimate, financing available. We answer the phone — usually on the first ring.
