Flat Roofing Questions
Why does water remain on part of my flat roof?
Roof slope, drainage layout, a blocked outlet or a low area can contribute to standing water. Its location and how long it remains are useful details to share during the evaluation.
Can standard shingles be used on a low-slope roof?
Roofing products have slope requirements. A low-slope section may need a different system from the steeper roof beside it. The material should be selected for that roof area rather than chosen only to match appearances.
What should a flat-roof replacement estimate include?
It should identify the roof area, proposed material, preparation, removal, roof-deck work, drainage details and treatment of seams, edges and openings. That makes it easier to compare the actual work being proposed.
Can you replace a flat section next to a shingle roof?
Lioncrest reviews low-slope areas and their connections to adjoining roofing. Tell us whether the project is a porch, addition, garage or another roof section so the transition can be considered with the replacement.
What affects the price?
Roof area, access, existing layers, deck condition and the amount of edge, drainage and flashing work affect the scope. The selected roofing material also matters.
What workmanship coverage is available?
Roofing workmanship coverage is 5 years with Basic, 10 years with Preferred, and lifetime with Premier. Your proposal identifies the package, materials and scope.
