New Roofs for the Information Philosophy Institute
G. F. Sprague proposal
This proposal is designed to provide durable, attractive, cost effective solutions to your:
Roofing Masonry Carpentry Metal Work Windows
PROJECT PREPARATION
Remove &:
Dispose Up To 1 Layers of Membrane(Flat Roof)
Dispose Up To 1 Layers of Masonry
Dispose Up To 1 Layers of Wood
Dispose Up To 1 Layers of Metal
There are no masonry, wood, or metal layers to be disposed of. There is a heavy 3-ply roof - roofing paper, asphalt (tar/bitumen), and gravel - underneath the EPDM membrane.
There is also the polyiso insulation layer mechanically attached by plates screwed through the tar and gravel.
Any additional layers will be removed at additional cost. The following proposal does
not include replacement of any defective framing, wood boards, masonry, siding,
insulation or other substrate materials that may be uncovered when the surface is
exposed. In the event defective wood boards are discovered, there will be an
additional charge for removal and replacement, not to exceed $9.95 per lineal ft. for
5/8” plywood or rough 3/4” boards. Replacement of any and all other substrate
materials to be priced separately. Replacement materials to replicate existing as
closely as possible per local suppliers current stock.
SUBSTRATE SURFACES:
Because the solar panels and their rack mounts will be attached to the roof boards, we want to secure them with 3-1/2 inch DeckMate decking screws, not nails, which can pull free with wind lift.
| IronRidge's Flat Roof Attachment is anchored to roof sheathing (and sometimes to rafters below) with 16 long screws. It is then capped with a large circular PVC membrane that can be heat welded or adhered to the roof. |
The integrity of your new / restored system depends on roof boards properly nailed to each rafter.
Over time, nails loosen and corrode. Each roof board will be re-nailed over the entire exposed
wood surface utilizing minimum 2 ¼” nails (existing nails to remain).
Low Slope Installation
Adhere Ice & Water Shield with: Grace
Areas of Work: Whole Membrane Roof
Additional Notes Insulation Board Installed
Additional Notes: If Option Selected
PERPENDICULAR WALL & FASCIA, ICE AND WATER PREPARATION
ICE AND WATER SHIELD:
GRACE ICE & WATER SHIELD® roofing membrane is used as an underlayment for
sloped roofs to resist water penetration due to water back-up behind ice dams or wind-driven rain.
It does not appear to be recommended for flat roofs.
A common roof leak problem in this geographic area is freezing ice in the gutters,
along the eave edge at valleys, penetration flashings, and transitions. Under certain
conditions this ice may expand up and under the roofing where it may melt when
exposed to attic warmth resulting in leaks. For double protection along the eave edge
it is recommended to fully adhere ice and water shield which is designed to stop any
expanding ice under the roofing from penetrating the deck, and infiltrating interior
spaces.
WOOD NAILER/UNDERLAYMENT/INSULATION
(Insulation systems pricing upon request. Not included in stated options.) Mechanically fasten new
pressure treated wood nailer at all open perimeter edges to accommodate new underlayment
insulation membrane. Mechanically fasten 1/2" HP high density fiberboard overlay substrates
utilizing FM approved fasteners and pattern to achieve I-90 (with roof removal) wind uplift
protection. You may elect to, or may be required to install additional insulation at additional cost.
The slope of the existing roof into the central drain is already adequate for roof drainage.
Tapered Insulation
Supply and install new custom tapered insulation system with HP fiber board overlay in an
attempt to create positive drainage. Contractor cannot guarantee roof drainage.
Mechanically Fasten: " .032 Aluminum
PERIMETER METAL
Termination of the new roof system to ensure the long-term watertightness from wind uplift,
protection provide control of water runoff and protect the underlying substrates. Install membrane
over edge cleats and penetrations flashings.
PERPENDICULAR WALL FLASHING/LOW SLOPE
Perpendicular Wall Flashing (low slope): Install membrane roofing to extend a minimum of 4" up the
walls, 18" up adjoining slopes. Install russ strip detail to prevent destructive bridging.
If new siding is required, there will be an additional cost.
ROOF DRAINS
Remove and properly dispose of any existing deteriorated drain, insert "sleeves.". Install new drain
bowl assembly integrated into the roof. Augment plumbing into the new roof set in a new drain by a
Ma licensed plumber specializing in roof related plumbing. Customer is responsible for detection
and correction of internal or augmenting plumbing.
FASCIA AND RAFTER PREPARATION:
Apply fresh coat of white paint to existing fascia board, add $7.78 per lineal foot. Replace fascia
with primed, back primed, as necessary. add $40.24 per lineal foot (slate tie-in may require
additional work adjustment at additional cost). Secure new rafter ends to existing as necessary,
add $83.83 per end. Composite board add $48.05 per lineal ft.
As per instructions, we propose to perform the following items of work:
Chimney is already down below roof, ready for new decking/sheathing..
Chimney Tear Down:
- Remove The Remaining Courses Of interior Chimney Down to 3rd Story
(interior Work to Be Contracted Outside our Scope)
- Install New Plywood Over Existing Penetration / Inspect for StructuralWork
- Ice and Water New Installed Board to Prepare For MembraneRoof Install
Inspect and Report:
- Customer is installing Solar to Roof Panel System Once Job Complete
- Inspect All Wood Below Membrane for Rot
- Inspect structure Beneath Plywood for any Additional Support
(Heavy Panels May Need More Supports)
- Inspect and Report for Additional Insulation Needed
(May work with Mass Save or other Customer Suppled Contractor for Insulation)
Per the attached scope and specification with the following options including:
