How to judge roofing work

A roof is the one system that protects every other part of a building, which is why the way a contractor inspects matters more than the brochure. A thorough look covers flashing, penetrations, valleys and decking — not just the field of shingles — because that is where water actually finds its way in.

Roof lifespan depends more on installation quality and attic ventilation than on the material alone. Poor ventilation cooks shingles from underneath, and incorrect nailing patterns void many manufacturer warranties. The useful questions to ask any roofer are about process and sequence, not only price.

Typical lifespan ranges by roofing material (industry averages; actual life depends on climate, ventilation and installation quality)
Material	Typical lifespan	Notes
Asphalt shingle	15–30 years	Most common; ventilation strongly affects service life
Metal	40–70 years	Standing seam generally outlasts exposed-fastener panels
Clay or concrete tile	50–100 years	Underlayment usually needs renewal sooner than the tile
Slate	75–150 years	Weight requires adequate framing capacity
Single-ply membrane (flat)	20–30 years	Seams and terminations are the usual failure points

What customers say

We have used Pond Roofing Company in the past, and our latest experience with them was equally excellent! This time, we hired them for a dryer vent stack repair and replacement, and they did a fantastic job. From start to finish, the communication and execution were top-tier. The office staff scheduled the work promptly and conveniently, and the project was completed quickly and professionally. What we especially appreciated came after the job was done: we received a detailed report with photographs of both the old and new materials, followed by a meticulous inspection. Every person we interacted with—from scheduling and the estimator to the crew and the follow-up inspectors—demonstrated an incredible level of care and professionalism. It is rare to find a company this thorough. We are highly satisfied and will absolutely continue to trust Pond Roofing!

Everyone at Pond was so kind and thoughtful when it came to what we needed. Our home insurance company required a roof replacement and our sales experience with Nic made us select Pond over the other quotes we received. He didn't try to push us to over spend and any recommendations he made were provided without being pushy. He actually made recommendations on ways we could save money. On top of that, the day the crew came to complete the job, they noticed a fan pipe for our bathroom vent laying in our attic and installed it for us (no extra charge :)). Installation only took a day but they came twice to ensure the site was spotless after. I'll be recommending them in the future for any of my neighbors looking to replace their roof!

The people at Pond are good people who do good work. I wanted to replace two old steel patio door with a more efficient fiberglass door. Cameon made sure I was getting the right door. Jennifer worked with me to schedule time for precise measurements and when the weather was not being agreeable for installation she twice helped me reschedule. The installation crew (Marcus, Handerzon and Raul) were great about fixing pre-existing conditions to make sure the door had a good foundation. They spent the extra time to make sure the installation was done correctly. Would definitely recommend Pond as a company that will do the work right the first time.
