About Roofer
Ice, water, and weather barriers worth paying for
In cold climates a self-adhesive membrane along eaves and in valleys prevents leaks from ice dams and wind-driven rain. Synthetic underlayment over the rest of the deck resists tearing during installation. These are cheap upgrades that stop the most common leak paths, so ask which layers the roofer plans to install.
Site protection and clean-up standards
Roofing is messy and dangerous. Confirm the crew will protect driveways, gardens, and walls with tarps and plywood. A magnetic sweep for nails should happen every working day, not only at the end. Ask where the dumpster will sit, who pulls the permit, and how the property is left at close of each day.
Seasonal timing and weather windows
Most asphalt shingles need temperatures above 4 degrees Celsius to seal properly. Spring through early autumn is the busy season, so booking 4 to 8 weeks ahead is common. Off-season work may cost less, but cold or wet days will be cancelled, which can stretch a 3 day job into 2 weeks.
Documentation to keep after the job ends
Ask for a written invoice listing materials, quantities, and labour, plus photos of the deck before underlayment goes down. Keep the warranty papers, the shingle batch numbers, and the roofer's contact details in one folder. If you sell the home, this paperwork reassures buyers and protects the remaining warranty.
What a roofer actually does
A roofer installs, repairs and replaces roofing on houses. Work covers the underlay, battens, tiles or metal sheets, flashing, ridge pieces and gutter edges. They also check timber structure, ventilation openings and insulation below the surface. Most roofers handle pitched roofs, flat roofs and roof windows.
Asking about licences and insurance
Ask for public liability insurance with a minimum cover of 1 million currency units. Request proof of training or trade certification in roofing. Confirm workers are covered for working at height. A written quotation showing registration details protects you if damage or injury occurs during the job.
Understanding the quote structure
A proper quote breaks down labour, materials, scaffolding, waste removal and VAT. Watch for vague line items like roof repair lump sums. Ask whether timber replacement, new flashing and ridge mortar are included. A quotation valid for 30 days lets you compare offers fairly between contractors.
What can push the price up
Roof height above two storeys adds scaffolding cost. Chimney removal, skylight fitting or solar panel detachment raise labour time. Sourcing reclaimed slate or specific clay colours costs more than standard stock. Steep pitches above 45 degrees usually require extra harness setup and safety equipment.
The importance of flashing and valleys
Flashing seals joints where the roof meets walls, chimneys and dormers. Lead flashing lasts over 50 years if fitted correctly. Valleys channel high water volumes and wear out first, so check them yearly. Poorly soldered valley seams cause most leaks reported within 2 years of a new roof.
Warranty and after-service expectations
Reputable roofers offer a workmanship warranty of 5 to 10 years. Manufacturer warranties on tiles or membranes run 20 to 30 years. Keep the job photos and material data sheets. Schedule a roof check every 2 years and after storms above 50 km/h wind speed to catch loose ridge tiles.
