House with a gravel roof. Do you replace? Tell me everything.

[Manuel Sarabia]

I think the correct term is gravel roof. I've seen it on a lot of the old houses in my area. Anyways, have you bought a house with this type of roof? If so, do you replace or keep? Have you tried both and have seen a difference in value?

I am thinking you are talking about a flat roof with tar and gravel.  I live in New Mexico and we have a lot off flat roofs with tar and gravel.  If the roofs are maintained, the flat roofs will last 15 to 20 years before they need to be replaced  The best option is to get at least 3 roofing contractors to look at the roof and get their advice.  You have to be careful as there are contractors that will tell you it needs to be replaced regardless of the condition.

I was speaking with a roofing contractor a few days ago and he told me about a product called Gaycor.  They claim to seal a flat roof for 50 years.  I have not experience with the product but will look into it when I need my next flat top roof replaced.

Good Luck
