We're near the water — what changes?
Exposed coastal sites carry higher design wind speeds and constant salt, and both change the specification rather than just the price: fastening patterns, what the roof assembly has to be rated for, which metals last and which stain within a season. Say you are on the shore in the first conversation. A specification written for an inland street does not survive on an open shoreline.
Wind is a fastening question first
Design wind speed is not weather; it is an input to the code. It rises as a site gets more exposed, and open water is the most exposed a site gets — there is nothing upwind to slow anything down, so a shoreline house takes the full load while a house four streets inland, behind other houses and trees, does not.
What that changes is not the brand of shingle. It is how many fasteners go into each one and where they land, whether the assembly has been tested and rated for the exposure, how the perimeter and the corners are treated — because the edges and the corners of a roof take far more uplift than the middle — and how the drip edge and starter course are secured. A roof that lifts almost never lifts in the field. It lets go at an edge and then unzips.
What your particular address requires is a question for the town's building department, and it is confirmed before a specification is written rather than after.
Salt does not stop
Wind is episodic. Salt is continuous, and it is the one that quietly decides how long things last.
It attacks fasteners first, because they are small and they are the thing holding everything else on. It attacks flashings, drip edge, vents, and any fixing that was chosen for price rather than for exposure. It stains: the wrong metal will run rust down a new roof within a season and no amount of cleaning brings it back.
It also punishes mixing metals. Put two dissimilar metals in contact, add salt water, and you have built a small battery that eats one of them. Fasteners, flashing and gutter should be chosen as a set, not one at a time by three different trades.
A specification written for an inland street does not survive on an open shoreline.
What to ask for on the specification
- The rating, named
- Not "wind resistant" but the actual rated assembly, and the fastening pattern that rating depends on. A rating only applies if the roof was installed the way the test was run.
- The metal, named
- For fasteners, flashings, drip edge and vents. Ask what happens to it in salt air and whether anything in the assembly is in contact with a different metal.
- Edges, corners and penetrations
- Where uplift concentrates and where salt gets in. Ask specifically how the perimeter is detailed rather than accepting a general answer about the roof.
- Underlayment and sealing
- The layer that matters once wind has driven rain sideways under something. Ask what goes down, over how much of the roof, and how it is lapped.
- Ventilation that does not let weather in
- Ridge and soffit venting on an exposed site has to breathe without admitting driven rain and snow. Not every vent designed for an inland roof does.
- What the manufacturer requires
- Material warranties are conditional on installation method, and the coastal method is often not the standard one. Ask what the manufacturer's instructions say for this exposure and get it in writing.
It is not only the roof
Whatever the wind and salt are doing to the roof, they are doing to everything else on that elevation.
Siding and trim on the weather side age at a different rate from the sheltered side of the same house, which is why one wall looks tired while the others look new. Windows and doors on an exposed elevation take driven rain at a pressure they were not necessarily specified for, and the flashing above them is doing more work than its counterpart round the back. Gutters and downspouts full of salt spray corrode from the inside.
So it is worth looking at the exposed elevation as one thing rather than replacing a roof and leaving the wall beneath it for another year. Water that gets past a wall detail ends up in the same sheathing the roof is nailed to.
Flood is a separate question from wind
People use "coastal" to mean one thing, and the rules treat it as two.
Wind is about what is above you. Flood is about where the ground is, and it comes with its own set of requirements — about elevation, about what may be built below a certain level, about what materials may be used there, and sometimes about whether a substantial improvement to an existing building triggers bringing more of it up to standard. Those rules are administered locally and they interact with insurance in ways that are worth understanding before you commit to a design, not after.
The town's building department is the place that answers this for your address. Ask early. It is a short conversation that occasionally changes the whole project.
What to say on the first call
That you are on the shore, and how exposed — open water in front of you, or a few streets back with houses in between. Those are genuinely different sites.
What has failed before, and where. A house tells you which elevation it minds about, and the history is usually more useful than any survey done on a calm day.
Whether anything is still letting water in. If it is, that is a phone call now rather than a form: (401) 405-8407.
Related questions
Do you do roofing?
Yes: repairs, replacements and new roofs, residential and commercial. A leak is worth looking at before it becomes a structural problem, so call rather than wait if water is already coming in.
What happens when the weather stops the work?
In New England it will, on anything exterior, and no honest schedule pretends otherwise. What you are owed is not a promise that it will not happen but a call when it does and a revised date — that is the difference between a delay and being left in the dark. There are also exterior materials that simply do not go down in the wet or the cold, which is a reason to wait rather than a reason to push.
Does my town need a permit for this?
Rhode Island permits at the town level — thirty-nine of them, each with its own forms, fees and review times — so the honest answer genuinely depends on where the property is and what is being done to it. Nobody can rule on your job from a web page, and it is worth being wary of anyone who tries. Tell the office the town and roughly the scope and you will get a straight answer for your situation.
I'm getting three quotes.
Sensible, and expected. The only thing worth insisting on is that all three are pricing the same scope: permits, disposal, which trades are included, and what happens when something unexpected turns up. Most of the gap between bids is a difference in what was left out, not a difference in what the work costs to do properly.
Do you guarantee your work?
Get it in writing before you sign, and be specific about which guarantee you mean. On the building side there are usually two, and they are not the same thing: the manufacturer's warranty on the material, and the contractor's own warranty on the workmanship — ask how long each runs and what voids it. On the accounting side the question to ask is what happens if a return has to be corrected, and who carries the cost of fixing it. The office puts its own terms to you on (401) 405-8407.
