How To Compare Re-Roof Estimates


Navigating the world of re-roofing estimates is no small feat. Many homeowners find the process daunting, confusing, and downright intimidating. It’s not uncommon to stare at two different estimates wondering why there’s such a significant difference in pricing. To simplify the complexity of comparing re-roof estimates, here are 14 crucial tips aimed to empower you and ensure you can make an informed decision.
1. Roof Measurements
Different roofing companies might measure in different ways. The accuracy of roof measurements can greatly impact material costs and labour charges. Always ask how they determined their measurements and ensure they’ve accounted for any unique structural aspects of your roof.


Understanding the various roofing terms can provide more clarity when comparing roof measurements from different companies.
2. Shingle Brand
Shingles differ vastly in terms of quality, durability, and price. When comparing estimates, ensure you’re comparing the same or similar brands. A cheaper estimate might use lower-quality shingles, while a pricier one could be factoring in a premium brand with a longer life expectancy.
3. Ridge Shingle Style
Ridge shingles not only enhance aesthetics but also protect the most vulnerable points of your roof. Are the estimates proposing standard ridge shingles or premium, high-profile options? This can influence both cost and durability.
4. Underlayment
This is your roof’s primary defense against water infiltration beneath the shingles. There are various types, from traditional felt to synthetic underlayments. Understand the benefits and drawbacks of each type and which one is being proposed in the estimates.
5. Ice & Water Shield
Especially crucial for colder climates, this adheres to the roof deck and provides added leak protection. It’s vital to compare where this is applied – just in the valleys and eaves or the entire roof? In colder climates, issues like ice dams can be a real threat, further emphasizing the importance of a proper ice & water shield.
6. Drip Edge
A properly installed drip edge ensures water is directed away from the fascia and deck edge, preventing potential rot. Materials can vary, with some being more durable and rust-resistant.
7. Wall Flashings

The type of metal used (aluminum, copper, or galvanized steel) and its thickness can impact the longevity and cost. Flashings need to be properly installed to prevent leaks at intersections and protrusions. The role of wall flashings cannot be emphasized enough; flashing plays a crucial role in maintaining the overall integrity of the roof.
8. Pipe Flashings
Ask about the material and design. A quality pipe flashing should have a proper seal to prevent leaks, and preferably UV-resistant properties to prolong its life.
9. Starter Shingles
Beyond aesthetics, they provide an additional layer of defense against wind uplift at the eaves. Verify if the estimates account for standard or enhanced starter shingles.
10. Number of Nails
It might seem trivial, but the number of nails used per shingle affects the roof’s resistance to wind and overall stability. Ensure contractors adhere to the manufacturer’s recommenquippingdations.
11. Ventilation
Adequate roof ventilation prevents heat and moisture buildup, which can cause damage over time. The benefits of proper roof ventilation extend from preserving the roof’s lifespan to maintaining the home’s internal temperature. Ensure the estimates cover the type, size, and number of vents being proposed.
12. Workmanship Warranty
This reflects a roofer’s confidence in their work. A longer warranty might suggest better quality, but always read the fine print. What scenarios are covered, and which ones are excluded?
13. Manufacturer Warranty
Beyond the general coverage duration, investigate the specifics. Does it only cover material defects? What about labour? Some premium shingles come with extended warranties, but there might be installation stipulations to validate such warranties.
14. Ask for Their Input
Engage each roofer in a detailed conversation. What challenges do they foresee with your roof? Are there any cost-saving alternatives or upgrades they would suggest given your home’s location and structure? Engaging with potential roofers is critical, and there are key questions that can help ensure you’re making an informed choice.
