When Do You Need a Roof Replacement?

Age-Based Assessment

Most asphalt shingle roofs in Massachusetts and Rhode Island last 20-35 years depending on the shingle type and maintenance history. If your roof is:

• •**Under 15 years old:** Repairs are almost always the right answer
• •**15-25 years old:** Assess condition carefully - repair or replace depending on the extent of issues
• •**25+ years old:** Replacement is usually more cost-effective than ongoing repairs

Condition-Based Signs

• •Multiple areas of granule loss (bare spots visible on shingles)
• •Widespread curling, cupping, or cracking across multiple roof sections
• •Multiple leaks from different locations (indicates systemic failure)
• •Moss or algae growth that has penetrated the shingle surface
• •Sagging or soft spots indicating decking damage
• •Visible daylight from inside the attic

The "Repair vs. Replace" Calculation

A useful rule of thumb: if the repair cost exceeds 30% of a full replacement cost, replacement is the better investment. A new roof also resets your warranty coverage and eliminates the patchwork liability of a repaired old system.

Understanding Roof Replacement Costs

Cost Factors in Massachusetts

**Roof Size and Complexity**

Roofing is priced by the "square" (100 square feet). A simple 20-square roof costs significantly less than a complex 25-square roof with multiple dormers and intersections.

**Material Choice**

Material cost is typically 40-50% of total project cost. See our [FAQ on Massachusetts roof costs](/faqs/how-much-does-roof-replacement-cost-in-massachusetts/) for detailed pricing.

**Decking Condition**

If existing roof decking is damaged, replacement adds $70-$90 per sheet of plywood. This is often unknown until tear-off begins.

**Accessibility**

Steep roofs, multi-story homes, and difficult access situations require additional safety equipment and labor time.

**Local Permit Fees**

Massachusetts and Rhode Island municipalities charge permit fees ranging from $100-$500 for roofing projects. Roofing Doctors handles permit acquisition as part of every project.

Getting Accurate Estimates

Request at minimum three written estimates. Ensure each includes:

• •Full material specifications (manufacturer, product line, color)
• •Complete scope (tear-off, decking inspection, underlayment, drip edge, flashing)
• •Warranty coverage details
• •Payment schedule
• •Timeline and crew details

Be wary of estimates that are significantly lower than others - they often cut corners on materials or use unqualified crews.

How to Choose a Roofing Contractor

Required Credentials

Every Massachusetts and Rhode Island roofing contractor must be:

• •**Licensed:** Massachusetts Home Improvement Contractor (HIC) license required
• •**Insured:** Liability insurance ($1M minimum) and workers' compensation
• •**Local:** Established business with a local address and phone number

Preferred Qualifications

• •No local references or verifiable business history
• •Vague estimates without material specifications

What Happens During a Roof Replacement

Day 1: Tear-Off and Inspection

1. Crew arrives, sets up safety equipment and tarps to protect landscaping

2. Remove all existing roofing material down to the deck

3. Inspect decking for soft spots, rot, or damage - replace as needed

4. Report any unexpected findings to homeowner before proceeding

Day 1-2: Underlayment and Flashing

1. Install new drip edge at eaves

2. Apply ice and water shield at eaves (minimum 6 feet), valleys, and penetrations

3. Apply synthetic underlayment across remaining deck

4. Install new drip edge at rakes

5. Install or replace all metal flashing (step, valley, chimney, pipe boots)

Day 1-2: Shingles

1. Starter strip installation at eaves and rakes

2. Field shingle installation from eave to ridge

3. Ridge cap installation

4. Final inspection and cleanup

Cleanup and Final Walk-Through

• •Magnetic roller across lawn and driveway to collect nails
• •Debris removal and disposal
• •Final inspection of all flashing, ridge, and penetrations
• •Walk-through with homeowner to review completed work
• •Warranty documentation provided

After the Replacement: Maintenance and Warranties

Immediate Post-Installation

• •Do not walk on the new roof for 30 days (shingles need time to fully seal in heat)
• •Check gutters after the first rain for granule shedding (normal with new shingles)
• •Keep your warranty documentation in a safe place

Annual Maintenance

• •Visual inspection from ground level each fall
• •Clear gutters of debris each spring and fall
• •Trim overhanging branches to prevent abrasion
• •Schedule professional inspection every 3-5 years or after major storms

Understanding Your Warranty

Your new roof typically has two warranties:

1. **Manufacturer warranty** - Covers defects in roofing materials

2. **Contractor workmanship warranty** - Covers installation errors

With Roofing Doctors' GAF Master Elite or CertainTeed ShingleMaster certification, you get access to the highest tier of manufacturer warranty coverage available.
