Should I do a full tear-off or add a layer over my existing shingles?

A full tear-off is the right call when existing shingles are curling, decking feels soft, or a second layer is already in place, since most jurisdictions limit roofs to two layers total. We strip everything to bare decking, inspect each panel, replace any damaged sheathing, then build the new system from scratch so underlayment and flashing bond correctly to a sound surface.

Does a roofing permit in Shrewsbury require a licensed contractor?

A building permit is required under Massachusetts 780 CMR for roofing work in Shrewsbury, and the Town's Building Inspector's Office handles all applications through an online permitting system. We hold MA HIC 205267 and manage the permit process on your behalf, with permit fees typically passed through as a line item in the written estimate.

What is included in an asphalt shingle job, and what costs extra?

We include tear-off and haul-away, deck inspection, underlayment, ice-and-water shield, flashing, drip edge, ridge and soffit ventilation components, shingle installation, cleanup, and a magnetic nail sweep. Structural decking beyond a small allowance, skylight unit replacement, gutter replacement, chimney masonry repair, and permit fees are typically separate unless specified in writing.

What shingle options are available beyond the standard three-tab?

We install four tiers: three-tab strip shingles at economy level; architectural laminates such as GAF Timberline, Owens Corning Duration, and CertainTeed Landmark at standard; premium designer laminates mimicking slate or shake; and impact-resistant Class 4 shingles. The right tier depends on budget, roof pitch, and how long you plan to stay in the home.

What workmanship warranty covers a new shingle roof?

We stand behind our workmanship with a 3-year warranty. If an issue is caused by our work, we'll return promptly to inspect it and make it right at no additional cost during the warranty period. Installed shingles also carry a separate manufacturer warranty tied to correct installation, which is why nail pattern, exposure, and underlayment lapping are checked at every stage.

How do I know if my decking needs replacement once the old shingles come off?

When decking is damaged, we identify soft spots, delaminated panels, and rot by walking the stripped surface before any new material goes down. Sheathing that flexes underfoot, shows water staining, or crumbles at nail holes is replaced rather than covered. The written estimate includes a small decking allowance, and any boards beyond that are documented and approved before work continues.

Do you install asphalt shingle roofing in Natick, Hopkinton, and surrounding MetroWest towns?

We serve the full MetroWest region, including Natick, Hopkinton, Holliston, Marlborough, Northborough, Grafton, Medfield, Millis, Medway, and surrounding communities in addition to Shrewsbury. A dedicated project manager coordinates scheduling and crew travel so the timeline in your estimate reflects the actual start date at your address.

Q: Which shingle grade is right for a New England roof?

Architectural laminate shingles are the standard choice for MetroWest homes because their dimensional profile sheds ice and water better than flat three-tab strips and their heavier mat resists the freeze-thaw cycling common here. We also install premium designer laminates and impact-resistant Class 4 shingles where hail exposure or HOA appearance requirements make them the better fit.

Asphalt shingle roofing for MetroWest homes

Seven Pines Home Improvement installs asphalt shingle roofing in Shrewsbury, MA, for single-family homes, typically $6 to $10 per square foot installed in 2026 and finished in one to five days depending on roof size. Services include full tear-off and replacement, ice dam prevention, roof flashing repair, roof decking replacement, gutter installation and cleaning, and flat roof repair.

An asphalt shingle roof is a full system, not just the shingles. It is the tear-off of what is failing, the deck underneath, the ice-and-water shield at the eaves, the underlayment over the field, and the flashing that seals every wall and chimney. Most of Shrewsbury's housing stock went up between 1970 and 1999, which means a lot of roofs out here are now on their second or third covering and running out of service life. If yours is curling, granule-bald, or leaking at a valley, this page covers what the work costs, how long it takes, and how to tell it was done right.

How we install an asphalt shingle roof: the seven steps

A simple ranch or small roof runs one day. An average single-family home with 20 to 25 squares takes one to two days. A large or complex roofline with multiple valleys and dormers runs three to five days. Weather moves the schedule, but a roof is never left open overnight. This is the order the work happens in.

Scope	Typical range (2026)	What moves the number
Small roof, 10 to 15 roofing squares (simple ranch)	Lower end of $6 to $10 per sqft	Flat pitch and a single plane keep labor hours low. One existing layer to tear off and sound decking hold the price at the floor of the range.
Average single-family, 20 to 25 squares	Roughly $12,000 to $20,000	Roof area, pitch, number of valleys, dormers, and pipe penetrations. Tearing off two existing layers instead of one doubles demolition and haul-away labor.
Large or complex roofline, 30 or more squares with multiple valleys and dormers	$20,000 to $28,000 and above	Steep pitch, numerous planes and valleys, and any soft or delaminated sheathing discovered once the old roof is off. Shingle tier also moves the number: a designer laminate costs more than an architectural standard grade.
Partial or slope-specific re-roof	Priced by the slope	Square footage of the specific slope, how it integrates with the adjoining field, and whether the existing flashing at the perimeter can remain or must be replaced.
Decking replacement beyond the small allowance	Priced per panel on sight	Number of soft or delaminated panels discovered during tear-off. Documented and approved before work continues. Homes with a history of ice dam leaks often require more than the standard allowance.
Permit fee, Shrewsbury Building Department	Typically passed through as a line item	Set by the town based on project valuation. We manage the application under MA HIC 205267 and include the fee as a line item in the written estimate.

How much does asphalt shingle roofing cost in MetroWest, MA?

Asphalt shingle roofing in the MetroWest and Worcester County area typically runs $6 to $10 per square foot installed in 2026. A typical single-family tear-off and re-roof lands around $12,000 to $28,000, and the range is driven mostly by roof size, the number of existing layers being removed, and the number of valleys, dormers, and penetrations the crew has to flash and seal. Every project is measured and inspected on site before a written estimate goes out.

Which shingle grade is right for a New England roof?

For most Shrewsbury homes, architectural laminate shingles are the right grade for a New England roof. They carry a higher wind rating and a thicker weather layer than economy 3-tab strips, and they handle freeze-thaw cycling and wind-driven snow better. The tier you pick depends on budget, roof visibility, and how long you plan to stay in the home. Here are the four options we install.

3-Tab Strip Shingles

Three-tab shingles are the economy tier: a single-layer fiberglass mat with a flat profile and a standard wind rating. They meet code and perform reasonably on low-pitch roofs with clean drainage, but their lighter mat is more vulnerable to the uplift forces and ice-dam cycling that are routine across MetroWest winters. If budget is the primary driver and the roof is simple, they are a workable choice. If the home has a steep pitch, multiple valleys, or a history of ice dam damage, a heavier laminate is the better investment.

Architectural and Dimensional Laminate Shingles

Architectural laminates are the standard choice for Shrewsbury and Worcester County homes. Brands such as GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark are all in this tier. The two-layer construction produces a dimensional shadow line that reads better on traditional New England homes, and the heavier mat resists the freeze-thaw lifting that eventually de-tabs economy shingles. Most of our re-roofs use this grade because it balances cost, weather performance, and manufacturer warranty coverage at the right level for this climate.

Premium and Designer Laminate Shingles

Premium designer laminates are engineered to mimic the profile of slate or cedar shake without the weight or maintenance demands of those materials. They work well on high-visibility roofs where curb appeal is part of the project brief, on homes in HOA communities with appearance requirements, or where a homeowner wants a finished look that is noticeably distinct from standard laminate. Cost is higher than architectural grade, and the installation process is the same, so the upgrade decision is primarily aesthetic and resale-driven.

Class 4 Impact-Resistant Shingles

Class 4 impact-resistant shingles are tested to UL 2218 standards against steel ball impact and are the right specification where hail exposure is a concern or where an insurance carrier offers a premium reduction for their use. Some MetroWest homeowners also choose them on steep, high-pitch roofs where wind-driven debris is an ongoing hazard. The mat construction is heavier than standard architectural laminate, which adds some freeze-thaw resilience as well. If your carrier offers a discount, the payback period on the upgrade is often shorter than it looks on the estimate sheet.

Most homeowners we hear from are not sure whether they need a repair, a partial re-roof, or a full tear-off and replacement. That is exactly the conversation we are set up for. Marcony Araujo and Romero Araujo founded Seven Pines Home Improvement on a simple idea: give people honest information before they spend a dollar. We hold HIC #205267, back every shingle roof with a 3-Year Workmanship Warranty, and hand you a detailed written estimate after an on-site inspection, before any work begins. Asphalt shingle roofing in the MetroWest and Worcester County area typically runs $6 to $10 per square foot installed in 2026, and the only way to land on a number that reflects your actual roof is to have someone measure it in person.
