What's covered

  • Roof Leak RepairWater rarely comes through the roof right above the stain on the ceiling. It runs along the deck or rafters first, so the repair starts with tracing it back: around chimneys, skylights, plumbing vents, valleys and wall joints, where flashing and sealant fail more often than the shingles themselves. The quote names the source, the repair and any wet or rotten decking that has to be replaced.
  • Shingle Roof ReplacementA replacement is more than new shingles. The old layers come off, the deck is checked and damaged boards are replaced, then ice and water membrane goes along the eaves and valleys, underlayment over the rest, new drip edge and flashing, and finally the shingles. Ventilation is part of the job too, because a hot, damp attic shortens the life of any roof. A good quote lists each of these items.
  • Roof InspectionsAn inspection covers the roof covering, flashing, vents and edges from outside, and the attic underside, insulation and signs of moisture from inside where access allows. It tells you whether the roof needs a repair now, can wait, or is near the end of its life. It is worth doing before buying or selling a home, after a major storm, or once a roof is around 20 years old.
  • Flat Roof Repair & ReplacementFlat and low-slope roofs are common on plexes, row houses, garages, additions and small commercial buildings. Most problems start at seams, penetrations, parapet walls and drains, or where water ponds. Depending on the condition, the fix may be a patch, a new layer over sound existing roofing, or a full tear-off with new insulation and membrane. The quote should explain which membrane is proposed and why.
  • Storm Damage RepairAfter high winds, hail or a fallen tree, the first job is to keep water out, usually with a secured tarp over the damaged area. Then the damage is documented with photos and repaired: lifted or missing shingles, cracked or bruised shingles from hail, bent flashing and broken decking. If you plan to file an insurance claim, contact your insurer early and keep the photos and written quote for your adjuster.
  • Flashing, Chimney & Skylight RepairMost roof leaks start where the roof meets something else: a chimney, a wall, a skylight, a dormer or a vent pipe. Old flashing corrodes, and sealant dries out and gets covered with more sealant instead of proper metal. A sound repair lifts the shingles around the joint, installs new step and counter flashing, and adds a cricket behind wide chimneys so water and snow do not collect there.
  • Ice Dam Prevention & Roof VentilationIce dams form when heat from the house melts snow on the upper roof and the water refreezes at the cold eaves. The water then backs up under the shingles and leaks into walls and ceilings. Chipping the ice off treats the symptom. The lasting fix combines balanced soffit and roof vents, air sealing and insulation in the attic, and ice and water membrane along the eaves.
  • Metal RoofingMetal roofs cost more up front than asphalt shingles but last longer and shed snow well. Standing seam panels hide their fasteners and suit houses and lower slopes. Exposed-fastener steel panels cost less and are common on garages, sheds and cottages. A proper quote covers the panel type and gauge, the underlayment, snow guards where snow could slide onto walkways or doors, and how edges and penetrations will be flashed.

How the work is handled

  • Repair Before ReplacePlenty of leaking roofs only need a repair. If a repair makes sense, the quote says so. If the roof is at the end of its life, you see why.
  • Written ScopeTear-off or overlay, decking, underlayment, flashing, ventilation, debris removal and disposal, all written down before any work starts.
  • Climate-Aware WorkSnow loads, ice dams, freeze-thaw, high winds and hail change what a roof needs. Local roofers take your area into account.
  • Clear OptionsWhen more than one approach can work, such as a repair, a new layer or a full replacement, you see the options and the trade-offs.
  • Homes and Small BuildingsHouses, cottages, plexes, row houses, small apartment buildings and small commercial roofs, sloped or flat.
  • Form Only, Your PaceSend the details when it suits you. Nobody calls you before you ask for a quote.

By climate

  • Long, cold winters with heavy snow and a short, warm summerHeavy snow loads and ice dams push water under shingles at the eaves, which is where most winter leaks start. Ask about ice and water membrane at the edges and attic ventilation in the quote, and book replacements for late spring through fall when shingles seal properly.
  • Wet maritime weather, salt air, many freeze-thaw cycles and storm-driven rain and snowWind-driven rain and storms lift shingles and test every flashing, and freeze-thaw keeps working small gaps open. Ask about high-wind nailing, sealed flashings around chimneys and vents, and an inspection after each major storm.
  • Four seasons: humid summers, cold winters with snow and repeated freeze-thawSummer heat ages shingles while winter freeze-thaw and the odd ice dam force water into weak spots. Fall inspections catch lifted shingles and cracked flashing before snow, and replacements go smoothest in spring or early fall on mild, dry days.
  • Hot, humid summers, mild winters, heavy storms and in coastal areas hurricanes; pests and mold all yearHeat, humidity and algae shorten shingle life, and hurricanes or hail can strip a roof in one storm. Ask about wind-rated installation, algae-resistant shingles and how the roofer documents storm damage, since demand spikes right after a major event.
  • Desert heat, strong sun and UV, dust, monsoon downpours, very little freezingExtreme sun cracks and curls shingles, dries out underlayment and breaks down flat roof coatings. Many roofers start before dawn in summer, and short, heavy monsoon storms reveal hidden leaks, so a pre-season inspection is worth asking for.
  • Dry, high-altitude climate with strong UV, big day-night swings, snow and freeze-thawStrong UV, hail and big temperature swings wear roofs faster than people expect, and snow at altitude brings ice dams. Ask about impact-resistant materials, ventilation to keep the deck cold, and scheduling around spring hail season.
  • Mild, wet marine climate: long rainy seasons, moss and moisture, little hard freezing near the coastMoss and constant moisture lift shingles and rot the decking underneath, more than heat or ice ever will. Moss removal and gutter clearing in fall help a lot, and replacements should be booked for the dry summer months when roofers can open the roof safely.
  • Dry summers and wet winters, wildfire smoke and ash, earthquakes, almost no snow on the coastDry summers age roofing and, in fire zones, embers can catch in debris-filled valleys and gutters. Ask about fire-resistant roofing and ember-resistant vents, and get leaks repaired before the first winter storms rather than during them.
  • Extreme cold, permafrost in places, very short building season and remote freightExtreme cold makes shingles brittle and roofs carry snow for most of the year, so the work window is short and busy. Book well ahead, confirm materials are shipped in time, and ask how the roof will be ventilated to stop ice buildup.

Every written quote covers

Questions

Do I need a new roof or just a repair?

It depends on the age and condition of the whole roof, not just the leak. A roof in decent shape with one failed flashing or a few blown-off shingles usually only needs a repair. Widespread curling, cracking or bald shingles, soft decking, or leaks in several places point toward replacement. The inspection should show you which one applies and why.

How much does a roof replacement cost?

It varies a lot. The price depends on the size and pitch of the roof, how many old layers come off, how much decking needs replacing, the material, the number of chimneys, skylights and vents, access, permits and disposal. A repair can be a small job, while a full replacement is a major project. The only reliable number is a written quote after an inspection.

How long does a roof last?

As a rough guide, asphalt shingles often last 20 to 30 years, flat roof membranes 15 to 30 years depending on the type, and metal roofs longer than both. Attic ventilation, installation quality, climate and maintenance can shorten or extend that.

Can new shingles go over the old ones?

Some building codes allow a second layer, but it hides the condition of the deck, adds weight and can shorten the life of the new shingles. A tear-off lets the roofer replace damaged decking and install new membrane and flashing properly. The quote should say which approach is proposed and why.

What should I do right after storm damage?

If water is coming in, move belongings away and catch the drips. Do not go up on the roof yourself. Take photos of the damage from the ground and from inside, contact your insurer if you plan to file a claim, and send a quote request so a local roofer can tarp and assess the roof.

Do you work on flat roofs?

Yes. Membrane roofs such as TPO, EPDM and modified bitumen, and older tar-and-gravel roofs on plexes, row houses, garages, additions and small commercial buildings. Mention the roof type in your email if you know it.

Do I need a permit?

Often for a full replacement, structural work or a change of roofing material, and rarely for small repairs. The rules depend on your municipality. A proper quote should say whether a permit is needed and who takes care of it.

How do I get a quote?

Email us your city, the service you think you need, and what you are seeing. A roofer who works in your area follows up to set up an inspection. Requesting a quote is free and there is no obligation to go ahead.
