Roofing question
Posted on 8/4/20 at 5:19 pm

Got estimates from a couple roofers for some repairs. Roof in general is still good. There are some ridge cap shingles worn thin or with holes in them. Rather than replace the bad ones, I want to replace all of the ridge cap shingles because I think it will look better since otherwise the new won’t match the old.
One roofer wants to remove the old ones before putting the new, whereas the other roofer wants to place the new ridge caps directly over the old.
What are the advantages/disadvantages of each method?

Sounds like an easy solution to extend the life of your roof.
I would probably go for the remove the old, but either way would be ok.
Any difference in price?

Still awaiting the breakdown of the second estimate, but definitely cheaper to place over the old ones because less labor involved - but the cost difference won’t sway me either way. I just want whichever way is best.

"I just want whichever way is best."

Then have them remove the old ones first.
In the old days, roofers used to nail new shingles over the old ones instead of ripping them off.

How old is the roof? Pulling the ridge shingles from an older roof will probably cause some damage to the normal shingles. Covering the old ridge shingles with new ridge shingles, the roofer needs to use longer nails to hold the shingles and there is a greater chance of wind damage to the new ridge shingles

Roof is 17 years old. Roofer says it has a good 7+ years left in it aside from some minor repairs.

I get the part about possibly damaging adjacent shingles if pulling off the old ridge caps, but I’m not understanding why using longer nails to go over the old caps makes the new ones more susceptible to wind damage...

Longer nails are needed to go through the old shingles, but I see multiple layers of shingles on roofs and in my experience, they are more likely to sustain wind damage. I think it is easier for wind to get under the multiple layers of shingles, I assume this would be the same for ridge shingles

Remove the old ridge caps and go with vented ridge cap.
“A ridge vent is an important part of a home's roofing system. Installed at the peak of a sloped roof, the ridge vent allows damp, warm air to escape from the attic. A properly installed ridge vent increases energy efficiency and prolongs the life of your roof.”

I would assume he already has a roof ventilation system, you don't want to miz multiple roof vent systems, they counteract each other.

I got rid of my roof ridge vents and went the whirrley bird route. House is much cooler in the summer now. Roof vents help the heat escape but not like a whirrley bird or powered one
