Gravel roof


I have a gravel roof that will be replaced with another gravel roof this summer. One of the bids said the old gravel will be re-used and new added where necessary. Another bid called for 100% new gravel. What is the preferred method and, if re-used, how is it cleaned?

Gravel roof


I hope this becomes an interesting thread because I'm in the same boat as you. 3/12 slope, 40'x30' footprint, tar and gravel, about 30yrs old, soon due for replacement. Looking into 2-ply or 3-ply systems, or any alternatives to what I have now, so have become a reader of this forum.

Where are you located, what climate zone, how old is your roof, any problems, have you been given an estimate?

Gravel roof


no reason not to reuse as much as possible in that situation,unless the gravel is moldy etc.
personally with that style roof I would look at IB Roofing systems,or Certainteed flintlastic,and with the 3 on 12(carlisle),you could even look at total waterproofing,add ventilation system,and shingles for longer life

Gravel roof


I decided to reuse the gravel. I've got guys screening it into buckets on the roof, sending the good gravel down to a barrel and, washing/rinsing in small buckets then dumping into large trash cans with drain holes. Anyone know the cost of gravel? I haven't priced gravel yet - don't know if I'm wasting time/money.

Very surprised you went back with BUR with gravel ballast.

Did your contractors offer mod bit or other options?

Get a price on new pea gravel (river rock). Local prices are transport driven.

I would be shocked if you could feed slave labor cheaper than buying new.
Your method is very labor intensive.

Now that you have your rocks scrubbed clean on the ground how is it going back up to the roof?

When you are ready the new gravel arrives in a lift truck that backs up to your roof line. walk board & wheel barrels take it from there.

That is a very good question. Have not thought about it.

I may be wasting time/money after all.

My roofers only bid on what I requested - a BUR with gravel. And, they are not doing the gravel cleaning.

Yes. A complete waste of time, labor, water to screen and clean the gravel.

Gravel roof


For the other readers of the thread ... Roofing God already mentioned it - www.IBroof.com

I'm always stunned by how cheap people can be when it comes to putting on a good roof.

I may be a fairly biased source - or not - depending on your perspective. I used to own/run a successful roofing company which did residential, commercial & government work.

In addition to that, I'm a computer consultant by trade (I got roped into roofing to help out my best friend).

So, I'm stunned by the idea of how to save money on a roof.

A few thoughts from a stranger:
  • If you're staying in your house for more than 4 years, invest in the best roof you can.
  • If it's a flat roof, the National Roofing Contractors Association says that after year 7 of an asphaltic roof, you'll need to do maintenance every year so that the roof lasts its 'full life'.
  • Even a BUR painted white gets up to 135+ degrees on a 95 degree day. A membrane roof - like IB - is usually 4-5 degrees hotter than the air...
  • IBs 50mil material will last longer than the BUR (gravel included) and there shouldn't be any maintenance.
  • The only time I'd consider gravel is when the roof is visible from everywhere (like your house is at the bottom of the hill)
  • Never overlay an old roof - ALWAYS tear off to the substrate
  • Never drop something to the ground which needs to be back up on the roof - the labor costs will outweigh any savings
The only gravel on a roof that you'd worry about being 'clean' is the gravel that your roofer embeds into the BUR (built up roof) - the rest of the gravel can be as moldy/dirty as you want.

Your roof protects your investment - it's not like a shrub out back. You want the best roof, and you want a competent roofer to do the work BECAUSE the wood substrate under the existing (dead) roof won't be looked at for another few decades. A lazy roofer, or a newbie homeowner will often overlook rot.

TVC15,

the real questions are how many squares? what is the price you are paying? Do you have any positive pitch on your roof?

can you attach any pic's ? what part of the world are you in?

really sounds like you are committed.

Avoid roofers who do not give you options, contractors who only sale one brand of materials, or one roofing system.

Avoid roofers who only give you a price on what you ask for, rather than giving you options.

You should attempt to get the best roofing system installed,
but saving money is ok also, just make sure you don't trade off quality for savings.

There is no such thing as a roof you can install and never look at again until the 20,30,40 year exspected life span is up,
but some will require less attention than others, so explore all options of suggested roofing systems for your type of roof structure.

In my area most every roofer i know gives free estimates, call 3 - 5 roofing contractors and get some choices.

Gravel roof


Response to Big Bob questions:

Squares: 14
Photo - attached
Location: Los Angeles, CA
Price: I have 5 bids for gravel BUR:
a) 4 ply - $6,000.00
b) 3 ply - $6,300.00
c) 4 ply - $5,800.00
d) 4 ply - $8,500.00
e) 3 ply - $4,500.00

I counted the base sheet #28 as a layer (ply). If I have
mis-applied the terminology, let me know.

So if you're still wondering what to do, why don't you use a cool roof?

Good luck.
