A new roof in Claremont runs about $13,000 – $27,500 installed on architectural asphalt shingle and $24,000 – $58,000 on concrete tile, for the 25-square roof that is typical of houses here. Modelled figures rather than quotes. What actually moves a bill is layers, soft decking and access, and none of those three can be known from a desk. That is a national base cost multiplied by a regional index of 1.365 for this area, with the full range by covering set out below. Most houses here fall between 20 and 29 squares.
Installed ranges for Claremont
Here are the numbers. Read the method underneath them before treating any of them as a price. Impact-rated asphalt shingle in Claremont runs about $850 – $1,300 a square installed, or $17,000 – $37,500 for a roof of typical size here. Rated life 25 to 35 years. Class 4 rated. Often earns an insurance discount where hail is a factor. Clay barrel tile in Claremont runs about $1,700 – $3,200 a square installed, or $34,000 – $93,000 for a roof of typical size here. Rated life 50 to 80 years. Often salvaged and re-laid over new underlayment rather than replaced. Architectural asphalt shingle in Claremont runs about $650 – $950 a square installed, or $13,000 – $27,500 for a roof of typical size here. Rated life 25 to 30 years. The default choice on most American homes, and usually the right one. Every one of those figures is arithmetic, not an offer. The method is underneath.
The things that make two quotes differ
The material is the part everybody discusses and rarely the part that moves the number. Ridge and intake ventilation upgrade in Claremont: $601 – $2,419. The cheapest thing you can do to make the next roof last its full life. These are modelled figures, not quotes: a national base cost multiplied by a regional index of 1.365 for this area. Nobody can price a roof without looking at it, and the model does not pretend to. The one that most often bites is the one nobody can see until the old roof is off.
Where these numbers come from
What these figures are: arithmetic on a regional index. What they are not: quotes, averages of local jobs, or anything anybody has agreed to do. A typical single-family roof in Claremont works out at about 25 squares in this model, with most houses between 20 and 29 — a square being one hundred square feet of roof surface.
The housing stock, and what it means for a roof
Housing stock is the least glamorous local fact and the most useful one. Claremont has a population of about 36,139 across roughly 12 square miles of land, which works out at about 3,000 people per square mile. The coverings that actually turn up on houses in Claremont are asphalt shingle, concrete or clay tile, metal, and low-slope and flat sections. That is a statement about the housing here, not about your house — but it is what a roofer expects to find, and it is what a quote is priced against.
Layers, decking and the surprises in between
What is under the top layer is the real question, and the honest answer before the tear-off is "we will find out". Tear-off, per layer per square in Claremont: $152 – $278. Two old layers costs roughly twice what one does to remove and tip. Rotten decking, per sheet replaced in Claremont: $100 – $200. Only found once the old covering is off. Always budget for some.
Which material makes sense here
There is no best roofing material. There is a material that suits this climate, this housing and this budget, and the local half of that is the half that gets skipped. Ember and wildfire exposure in Claremont: Class A assemblies and closed-off vents matter more here than the colour of the shingle. Offshore wind events in Claremont: These winds are not constant, which is the problem. A roof gets nine quiet months and then one night at fifty miles an hour, and whatever was marginal goes. UV load and thermal cycling in Claremont: Sun is the main wear here. Asphalt loses its oils, underlayment goes brittle, and sealant beads shrink away from the flashing. The right answer is usually the boring one, chosen for a local reason.
About coverage in Claremont
Everything on this page is about Claremont specifically. The service itself is simple and worth stating plainly: it arranges quotes from up to three independent local roofing contractors and does not carry out roofing work.
