How much does it cost to put a new roof on an Older RV?
A new roof may be all it takes to get your older RV into a useable condition.
So how much does it actually cost to put a new roof on an RV? The answer is about $350.00 per linear foot.
So if you have a 30' RV, 30 x $350 is $10,500.
RV Roof replacements cost so much because they are very labor intensive. RV Repair shops typically estimate the replacement costs per linear foot. Completing the estimate involves itemizing all the materials and labor costs.
Here at At Your Door RV Service we offer some great advantages over other shops:
First, we are strictly a mobile service so we do all repairs on site. That means you don't have to move into a hotel, tow/drive your rig to a far away shop. In most cases you can live in it while repairs are being performed.
Second, we use a much tougher 60 mil fiberglass imbedded TPO commercial roof membrane. If seams are required, we heat weld the seams making a one piece roof.
Most roof membrane damage is caused by driving under branches or other obstructions. The EPDM rubber or PVC roof membrane installed on most rigs is 0.029-0.040" thick with no reinforcing. It simply tears. That won't happen with our roof.
Here we have broken out some basic RV roof replacement costs.
Replace roof membrane labor:
1hr per linear foot
Replace Roof decking and Luan:
1hr per 4ft of roof (round up) – (ex. 33ft roof = 9 sheets/ 9hrs)
Required removals and installs (R&I) of old materials:
Front cap molding – 1.5hr
Rear cap molding – 1.5hr
Left and Right upper side (gutter) moldings – 2.5hr /each
Powered Awnings if required – 3hr each
Slide out toppers and manual awnings if required – 2hr each
Aluminum Radius- (per unit basis) –
*not all RV’s will have radius
Labor = 1hr per every 7ft
Roof decking- Luan (4×8’ sheets)
$25 per sheet
Replace roof membrane material costs :
21’ = $420
25’ = $500
30’ = $600
35’ = $700
40’ = $800
Sealants and adhesives-
5 gallons TPO Contact adhesive -$250
Additional Sealants for roof appliances and moldings (Lap and Pro Flex)- $15.00 each:
Plumbing vents – 1tube per vent
Satellite, skylights, fridge vents, solar panels, etc. – 3 tubes each
Roof A/C gaskets per A/C – $25.00 each
Aluminum Radius- (per unit basis) – not all units will have radius
Radius material = $5 per foot
Roof disposal – $20.00
Final detail – 2hrs
(This is includes covering coach and interior during replacement process, final clean up from dust and debris, as well as the final wash/ water test.)
So using this information and an average 40’ RV, this is what the estimate might look like:
Line Description Part Number Qty Price $ Labor
1 Roof Membrane 60 Mil TPO Fiberglass Imbedded 1 $800.00 40.0 Hrs
2 Luan Decking (4x8 Sheets) 10 $25.00 $250.00 10.0 Hrs
3 Aluminum Radius Left Side 40′ $5.00 $200.00 6.0 Hrs

5 TPO Roof Adhesive 5 Gal 1 $250.00
6 Additional Sealants And Adhesives (See Notes) 15 $15.00 $230.00
2 Plumbing Vents (1/2 Tube Each) = 1 Tubes
1 Satellite – 2 Tubes
1 Skylight – 3 Tubes
1 Frigde Vent – 3 Tubes
2 Roof Vents – (3 Tubes Each) = 6 Tubes
8 Front Cap Molding 1.5 Hrs
9 Rear Cap Molding 1.5 Hrs
10 Left Upper Side Molding/Gutter 2.5 Hrs
11 Right Upper Side Molding/Gutter 2.5 Hrs
12 Right Porch Awning (Electric) 3.0 Hrs
13 Left Slide Out Topper 2.0 Hrs
14 A/C Gaskets (2) 2 $25.00 $50.00
15 Roof Disposal 1 $20.00
16 Final Detail 2.0 Hrs
SUBTOTALS $2000.00 77.0 Hrs
Labor 77.0 hrs @ $ 150.00/hr $11,550.00
So for a 40’ RV roof replacement, it comes to about $14,000, or $350 per linear feet.
