When felt roofing enters the decision
Felt may be considered for a new flat roof or renewal of an existing covering. Start with the roof requirements and the condition beneath. A leaking felt roof may still suit a local repair, so establish the problem before choosing full replacement.
Understand the specified felt system
Different felt specifications use different products and application methods. The layers and laps work with compatible edge and junction details. Ask the quotation to identify the proposed system rather than using a broad description that leaves the actual construction unclear.
Check the supporting roof build-up
The deck, falls and insulation need assessment alongside the covering. A new surface cannot correct every underlying issue. Clarify whether existing layers will be removed and what happens if opening the roof reveals damp or damaged supporting material.
Installation and quote considerations
Preparation, access and weather conditions affect installation. The selected application method also has its own safety requirements, which the contractor needs to plan for the site. Ask how occupied areas and adjoining materials will be protected.
Compare options and take the next step
Compare felt with EPDM and GRP using the same roof requirements and work scope. Provide the existing roof history and priorities. A clear quotation should include the edges, outlets and adjoining details, not just the area of covering.
Your questions, answered.
Are all felt roof systems installed the same way?+
No. Products and application methods vary, so the selected system must be identified.
Can a new felt system be installed over the old covering?+
Only where the existing roof and chosen system make that appropriate; it should not be assumed without assessment.
What should a felt roofing quote include?+
The specified system, preparation, supporting layers, details, access, removal where needed and any exclusions.
