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

What a pleasant experience Mario and his crew provided! Despite the distance to our home, Mario made sure the roofing job was done properly. Communications, job diagnosed, explained and completed as promised. We would recommend Delgados Roofing to assist you with your roofing needs, large or small!
Donna Pribyl

Mario worked with our HVAC contractor to complete a repair on our roof. He was easy to work with and gave us exact bids.. He had to make one small change during the process, and came to us directly with the exact amount that it would cost and told us exactly why we needed it. He took pictures of everything so we could see what the problems were and what we were paying for. He was extremely professional, and his crew was hard-working and prompt. They came exactly when they said they would, worked hard, and left the yard spotless when they were done. I would recommend Mario and Delgado roofing to anyone.
Rachel Murdock

I can't say enough good things about Delgado Roofing! They replaced my roof & gutters a week or so ago, and it was a great experience from beginning to end. The quote was comparable, changes were communicated quickly, and everyone on the crew was kind, friendly, and worked so hard. I'm so very appreciative ..
